Speculative Fiction Writers Guide to War, part 18: War Costs Exercise 1–Food for the Army

Ready to calculate some war costs? This exercise breaks down how much it would take to feed fantasy troops based on a late medieval army–and how much it would cost in relevant currency.

Travis P here. In spite of the original date of this post, nothing we say has any direct connection to Valentine’s Day or romance (sorry!). Instead we’re continuing on with providing you a set of numbers you can use, if you ever chose to do so, in order to calculate what an army needs. My fellow Travis is leading the way this week:

Travis C here. As you saw last week, this topic is huge, and rather than try and combine informational content with illustration, we’re going to split things up for a bit. Travis P introduced us to food supplies over the ages. He covered a spectrum of periods and practices from ancient days till modern times and speculated upon futuristic scenarios in sciences fiction and fantasy environments.

This week, I want to build an example calculation using data that he provided along with some other resources. I’ll keep the story going as we discuss varying forms of supply and support, capital costs, and other cost-of-war-related themes. This post will accomplish two purposes: first, to give you a story context and second, to develop a relative cost estimate based on Travis P’s food post last week and how that might influence a story.

My entering assumptions:

Fantasy worlds are often modeled after the Middle Ages as we perceive them, ranging from the Dark Ages through the High Middle Ages. Because of the interesting data available for this time period, I used the time of the Hundred Year’s War, the 1415’s specifically. Several factors impact these calculations that don’t necessarily “scale,” but it was a place to start from. (Note that futuristic science fiction story worlds would be better modeled based on the needs of armies from our own times.)

Morning of the Battle of Agincourt, 25 October 1415, painted by Sir John Gilbert in the 19th century

For medieval warfare, two types of activity dominate: putting armies in the field, and castle warfare (i.e., occupation politics). For castle warfare, we have both a defensive mode, building castles to preserve or hold a condition, and an offensive mode where castles are used as a strong base of operations from which to launch expeditions. We’ll start with fielding an army.

The purpose of this exercise is to develop enough information about the logistics of an activity in warfare so my story can be told without the reader assuming unbelievable events and to see if the logistics of a war can be used to develop interesting plot points, tension, and conflict. This exercise might be a starting place if I were to write a military fantasy, but as we’ll see, this will be insufficient to satisfy the superfan of that genre.

When we get to it, we’ll base our currency off the English system and maintain similar relative values to the 1400’s:
1 pound (£1) = 20 shillings (20s)
1 crown = 5 shillings (5s)
1 shilling = 12 pence (12d for denarius)

Scenario: Lady Katie and the Mad King Crabcakes

The Queen of New Landia, the Lady Katie, is in trouble. The neighboring realm of Old Seaside has made a claim on the throne of her realm and rallied their banners to wage war against her own baronesses and herself. She has firm control of lands surrounding the capital city, Awesomeness, but her border with Old Seaside is relatively unprotected and vaguely defined by a forest. Wide rivers defend her remaining borders.

Rumors from her spies indicate the Mad King Crabcakes can field an army of 500 horse, 3000 foot, and 2000 archers plus attendants and that he plans to launch a major campaign within a year while testing New Landia’s defenses in the meantime. The strength of King Crabcakes’ forces drops significantly away from his stronghold on the coast, but there are at least 6 minor and 3 major fortifications between her border and King Crabcakes’ stronghold.

Clearly there’s a lot left missing, but let’s go with this until we need to create more. Lady Katie must face a hard choice to begin with: does she meet the Mad King in the field, or does she put up a strong defense through building or capturing castles? Either method will cost her time and money and she’s limited in both. She gathers her advisers to assess the situation. For this post, we will only look at the first of her options.

Fielding an Army

Like all good rulers, noble Lady Katie knows her baronesses and the condition of their lands. Clearly, Lady Katie needs to draw forces if she meets Crabcakes in the field. Her advisers suggest she wants at least a 10% greater force to assure victory, so she’s trying to field 550 horse, 3300 foot, and 2200 archers. Plus all the support services necessary to remain afield for no less than 6 months (we’ll assume the fighting season lasts 6 months and then, by traditional obligation, she allows vassals to return home, necessitating the length of the campaign.) We’ll exercise our endothermic assumptions by fielding a dozen sapient war wolves, and to further challenge our ectothermic assumptions, she gains access to a dragon to lock up her chances.

I think we’ll delve into this in future posts, but let’s make a couple of assumptions to get us an army to put in the field, and some conditions she and her advisers will consider when calculating the cost of food:

1) When we say 550 horse, we’ll assume 400 knights and 150 skirmishing-capable riders (for pickets, scouts, messengers, and skirmishing duties.) Each knight has at least two attendants (squire/pages) in the field, and three horses (a warhorse, a riding horse, and a pack horse). At this point, we’ll assume the attendants will not have their own mounts. The skirmishing force each require two horses for their duties.

Total knights: 400
Total attendants for the knights: 800
Total skirmishers: 150
Total number of horses: 1500 (we’ll un-conservatively assume a horse is a horse, of course. That’s not true, as a charger’s needs will vary compared to palfreys, coursers, and pack animals.)

Lady Katie gets these through her baronesses as a feudal obligation. We’ll discuss their cost later.

2) The 3300 foot come from various sources. Some are her standing forces that occupy her lands’ castles and fortifications, which she draws down to provide soldiers for the army (let’s assume 300 of them). 2000 will come from feudal obligations from her baronesses’ lands. Another 1000 will be paid soldiers from other lands performing as mercenaries. She’ll pay for these via scuttage that we’ll discuss when we talk wages. While the majority of these soldiers will travel afoot, some portion do have horses to be used for their unit’s obligations. Let’s assume that’s 5% of the non-garrison force.

Total foot soldiers: 3300 (1000 mercenaries)
Total number of horses: 150

3) The 2200 archers come from her land’s feudal obligations as well, as every person is expected to shoot on Sundays by tradition. Half of this force have horses (one per soldier) to enable rapid deployment across the battle space, the remainder are afoot.

Total archers: 2200
Total number of horses: 1100

So just the regular fighting forces, not logistics support or engineers or anything else (other than squires), we end up with:

Total soldiers to feed: 6850
Total horses to feed: 2750

How much food?

Let’s look at the horses first. We may revisit this topic, and I don’t intend to provide a rigorous analysis of horse use in combat at this point, but according to a World War I source on horse care, I’ll use a median value of 11 lbs of oats and 10 lbs of fodder for each horse every day (irrespective of type; clearly an incorrect assumption, but sufficient for now).

2750 horse x 11 lbs oats = 30,250 lbs per day
2750 horse x 10 lbs fodder = 27,500 lbs per day

At 2500 lbs per wagon drawn by a brace of oxen, that’s about 12 wagons a day for oats, and 11 for fodder if it’s not available. Let’s assume she wants to have the horses forage for fodder to the maximum extent possible to extend her supplies. If I use a simple assumption that we can look at in more detail later that an acre of grass can produce 2000 lbs of fodder in a year, with a 9 month season it can be relied on for fodder, we can consume about 7.5 lbs per day per acre without leaving the land decimated. Lady Katie’s horses could consume as much as 3700 acres per day (about 5.8 square miles per day). Historical accounts suggest swaths of up to 10 miles wide being destroyed by a passing army, and now we can understand why.

Since in today’s market, wheat is about twice as expensive as oats, I’m using this reference to estimate my cost of oats at 4d/bushel, and a bushel of oats is about 32 lbs, so my daily cost of oats is:
30,250 lbs x (1 bushel / 32 lbs) x (4d / bushel) = 3781d, or 315s or £16/day
= ~ £2900 for a 6 month campaign (I’ve also found references that suggest this could be at least twice as high!)

For the people, let’s start with the simpler scenario: humans.

Using Travis P’s estimates from last week, I made some simple estimates for how much a person will consume per day:
1 loaf of bread @ 800 grams (this is higher than necessary)
⅕ of a chicken @ ~150 grams
1 qt of ale
1 qt of milk
Modify the costs by a factor of 150% to account for error, any supplements like sauces, etc.
Modify that result again by 150% for the knights assuming they will eat better fare
Estimate this all weights in around 5.5 lbs/person/day

Based on a mix of 1300’s prices (which we will share later), that works out to:
0.3 pence for bread
0.4 pence for chicken
0.2 pence for ale
0.05 pence for milk (assume ¼ the cost of ale)
Total: 0.95 pence x 1.5 = 1.425d (let’s round to 1.5 pence per soldier per day)
And lastly, 1.5 pence x 1.5 = 2.25d for nobles and knights

So with our merry band of 6450 human soldiers and 400 knights, we get:

1.5d x 6450 soldiers = 9675d, or 806s, or £40.
2.25d x 400 knights = about £4.

Let’s round that to £45 per day. In 2019, that seems cheap. If I use a simple relative conversion though, we see it’s pretty significant: in modern times, a loaf of bread alone costs about £0.25, or 60 pence a loaf, compared to our 0.3 pence. So that army costs a modern estimate of £9000 per day, or £1.6 million for our 6 month campaign! And think of everything we didn’t factor in:
Transport of the foodstuffs
Actual variability in the menu we purchased
Preparation, cooking, serving, clean-up
Any of our camp followers and support staff
Whether that food is immediately available when we want it

I want to check my math here and use a different measure, from a resource we will share in a future post:
Price in 1380 to feed each member of a household: lord, 7d; esquire, 4d; yeoman, 3d; and groom, 1d.

400 knights x 7d = 2,800 pence/day
6,450 soldiers x 3d = 19,350 pence/day (I lumped my squires into the yeoman category)
= 22,150d, 1,845s, £92/day (about twice what I estimated first)
= £16,600 for a 6 month campaign!

I’ll assume the higher amount for now to be conservative.

Endothermic Creature Calculation

Dire Wolves (an extinct species of very large wolf). Source: US National Park Service

Bear in mind that our standard Medieval figures only apply to creatures who actually lived in the medieval era. So how do we account for fictional creatures, like Lady Katie’s war wolves? I think we’ve got two possible approaches. She’s bringing a dozen in the field with her, and let’s say they weight in around 200 lbs (a little larger than the extinct species of dire wolves that once lived on Earth). The first thing we could do would be to scale up the average consumption of the closest living animal to our fictional creature, in this case a real wolf: our war wolf is a little more than 100% larger, and wolves consume around 10 lbs of meat per day (not necessarily in a single day though), so we can assume the war wolves will need twice that amount.

12 war wolves x 20 lbs meat/day = 240 lbs of meat per day

Based on assumptions about cows that follow, I can anticipate 1 cow lasting 3 days, so we need another 60 cows for a cost of about £25 for the campaign to feed the wolves. Alternatively, I could use Travis P’s recommendation on BMR and attempt to scale the caloric intake for our war wolves. Since the 200 pound figure I’ve been using equals about 90 kilograms, a BMR for a war wolf would amount to approximately 90 kilograms ^.75, but such a figure is so general that it would have the wolf wind up with the same approximate BMR as a 200 pound human!

While a war wolf weighs in near the size of a large man, for whom Travis P listed a figure of 2,500 calories per day as a reasonable calorie per day intake, my sense is a wolf will have higher caloric intake than a man. Travis P may have accounted for this by mentioning that creatures with higher metabolisms use more calories per hour than creatures with lower metabolisms. One way we would know if a creature has a higher metabolism is if its internal body temperature were higher than a human beings. Is that the case for wolves? According to one online source, the answer is no, because humans and wolves have the same internal body temperature, 37° C / 98.6° F.

The other way Travis P may have accounted for this was by mentioning that while humans rarely exceed more than twice BMR while active, many other creatures have a much higher multiple for their BMR when energetic. He stated the BMR for a healthy adult human male is “about” 1800 calories–let’s round up to 2000 for simplicity. A human working hard may double that caloric intake a day or possibly even go over double by a significant degree, but an active wolf may go much higher, perhaps as high as 4 to 5 times that amount, based on a comment Travis P made in the previous article. That would mean a war wolf would use approximately between 8,000 and 10,000 calories per day.

Based on the figure of approximately 1,100 calories in a pound of meat from the list of Colonial rations in last week’s post, that would mean a war wolf would require between 7 and 10 pounds (3.2 and 4.5 kg) per day of meat. Which is about half the figure obtained from the simpler calculation based on what wolves eat per day, though that figure came from a source that may have referenced what wolves eat when given the chance as opposed to their minimum needs.

In any case we now have two figures, one pointing at a minimum of about 10 pounds a day and the other at 20. To conservatively ensure we have enough food, we’ll use the figure of 20 lbs of meat per day.

Ectothermic Creature Calculation

Since in the story world of Lady Katie a dragon is an endothermic creature rather than an animal with a minimum BMR like a wolf, the kind of calculation we just did won’t really work here. Thankfully Travis P gave us some relief when considering ectothermic creatures. Since they cannot regulate their internal body temperature and rely on the environment, we have some thumb rules for how to calculate their caloric intake. We’ll use those estimates to gauge our dragon’s consumption costs.

I’ll approach this the simpler of two ways: using the example of the 300-some kg crocodile Travis P gave (as opposed to more thorough calculations using his breathing rates). I also will assume out of that 6 month campaign that the dragon is lazy (for which I will use the SMR for 10° C /50° F that Travis P gave) and active for 3 months (for which I will use the SMR for 30° C / 86° F), respectively. If it were our crocodile:

3 months x 30 days/month x 180 calories/day = 16,200 calories
3 months x 30 days/month x 720 calories/day = 64,800 calories
81,000 calories (the sum) x ~720 calories/300 grams of meat = 194.4 kg, or about 430 lbs.


Now for my crocodile-to-dragon conversion: I’ll assume a 15 tonne (15,000 kg) dragon based on Naomi Novik’s Temeraire series and assume that caloric intake scales directly. Our crocodile weighs in at the upper end of the scale at 390 kg, so:

430 lbs of meat x (15,000 kg / 390 kg ) = ~16,500 lbs of edible meat

From my earlier reference, a good cow costs about 9s and we’ll assume I get ⅔ of the ~1300 lbs average weight of a range cow down our dragon’s gullet.

Number of cows for the six months = 16,500 lbs / 867 lbs/cow = 19 cows
Cost of cows = 9s/cow x 19 cows = 171s or about £8.5

In practice, this looks like 1 cow every 9 days or so. I suspect Lady Katie’s dragon will exert more energy because he will be more active in combat and require a full cow per day (if I were a dragon I wouldn’t work for any less).

Cost of cows for the dragon = 6 months x 30 days/month x 1 cow/day x 9s/cow = 1,620s or ~£80

Total Cost for 6 Months Afield

Let’s wrap this up and do a quick analysis:

Total food costs:
Soldiers: £16,600 (I’m going with our higher end estimate for conservatism)
Horses: £2,900
War wolves: £25
Dragon: £80

Total £19,605

Again, remember that Lady Katie has paid no wages, hired no combat support, nor provided for any form of logistics to get this food to the army, and this assumes she allows the horses to forage for fodder every day. This is therefore an estimate based on the cost of food alone, not including anything else.

This feels like a long nerded-out math problem that has little direct relevance to us as authors. I certainly don’t suggest that we all need to have spreadsheets capable of doing this math, nor that we must be highly accurate when doing it. You are all likely great Googlers and can do research relevant to your story. But some things stand out in my mind:

The cost/horse (£1.05/horse) for food is lower than the cost/person (£2.50/person). This surprised me, and gave me a rough estimate that a horse-born soldier costs about 40% more than a foot soldier to support (in cost of food alone). It’s also much lower than £80/dragon but comparable to £2.08/war wolf.

Changes in food sources, especially access to grazing for horses and good range cows for dragons, can have a significant impact on the food budget; no surprise there.

Assuming a wagon can carry ~2500 lbs of goods, this army needs at least 20 wagons to support the horse feed alone, and nearly 13 to support the soldier’s food per day. Once we factor in drovers and teamsters, I have an entire storyline just related to the potential transportation of foodstuffs.

Inflation will impact these figures, so I should have some measure of relative worth to compare to. We’d call this something like useful purchase power, which we will address in a future post.

Any of those can be exploited for world building exposition or for a unique plot point. Maybe even a great secondary character like the drover for wagon number 17. We’ll keep delving into Lady Katie’s fictional war as we explore paying for her soldiers and later with the costs of castle warfare.

According to the Label

While the label of “a creative” is in one way too vague, it is in another too exclusive.
| Feb 13, 2019 | 5 comments |

There is nothing categorically wrong with labels. Labels are short-hand descriptions, a fast and easy method of classification – much like words. There is nothing wrong with labels just as labels. But labels, like everything else in this world, can go wrong. Some labels are active lies; others (not nearly so bad) are so insufficient they create more confusion than clarity, or so vague they are almost useless in conveying information.

Which brings us to the label “a creative”. As you know, this word (recently converted from an adjective to a noun) has become a popular self-label in recent years. It’s thrown out in blog posts, claimed in profiles. It appears to be roughly synonymous with “artist” – not by definition but by use (one senses that the “creatives” are not accountants).

The primary failing of this label is that it lacks a clear and specific definition. If you tell me that you’re a creative, I believe you, but I don’t know what you mean by it. Are you a musician, a writer, a painter, an actor? Or is it less a single talent or pursuit and more a way of thinking? Let me put it this way: An artist is defined by what he does (art). Is a creative likewise defined by what he does, or is he defined by what he is (creative)? I don’t know. I don’t understand the label.

I’ve poked around the Internet and discovered eloquent and elaborate definitions of what a creative is; these people aren’t pulling definitions out of a Dictionary. Some people understand the label. But they don’t always understand it the same. If they were operating out of a Dictionary, we would have a simple and reigning definition. But since they are instead spilling four hundred words to define a creative as they understand one to be, the meaning of the label is fluid. And the usefulness of a label is inversely proportional to the fluidity of its meaning.

While the label of “a creative” is in one way too vague, it is in another too exclusive. The label is generally applied to people who are creative in an artistic sense, but there are a thousand other ways to be creative. A person who can take a recipe off the Internet and make it twice as good is creative. People who come up with new and better operating procedures, that engineer or programmer or CEO who can see the way around the obstacle – they are all creative. Whoever first invented the assembly line was very creative. By God’s many and marvelous gifts, the world is overrun by creative people. A label for creatives that acknowledges only one kind of creativity is flawed; it encourages a false distinction, an unhelpful delineation between us and them.

Labels matter – because they are categories, because they are descriptions in brief, because they share the fundamental purpose of all words: to build a bridge. It is important, then, to choose your labels carefully. Before adopting, or bestowing, a label, we must consider what information the label conveys, and what judgments it implies.

Enclave, Thomas LockeIt’s been 50 years since the Great Crash and what was once America is now a collection of enclaves, governed on the local level and only loosely tied together by the farce of a federal government. Catawba, one of the largest and most affluent enclaves in the southern states, is relatively stable and maintains a successful business of trade with nearby enclaves, including the one at Charlotte Township. But when a new vein of gold is found beneath the feet of those in Catawba, it’s only a matter of time before trouble finds them.

Now the future of Catawba may be in the hands of an untried 21-year-old trader named Caleb. And Caleb knows that if his secret were ever to come out, he would never see another dawn.

For those who may have missed Sarah’s winning entry, here it is again:

By Sarah Duffy

The guard would never let me enter if he knew what I was planning.

The airport inspector and guard would never let me enter if he knew what I was planning—and hiding.

Right now I was being screened such at customs, for metals or explosive devices. What the airport inspector didn’t know was that a Bible was stashed away in the false bottom of my carry-on bag.

In this country it was illegal to import Bibles. It was illegal to be a Christian. It was even illegal to own a Bible. That’s why I was helping my friend Edward smuggle Bibles.

I held my breath as the airport inspector looked me over, hoping and praying he wouldn’t find me out. Or my secret. He patted me down and used his metal detector. Nothing. No metal, no explosive devices, nothing. He grunted.

“Go ahead, ma’am,” he said. “You’ve got nothing illegal on you.”

I smiled and moved ahead. I was through all customs, all inspectors, now all I had to do was figure out a plan and get the Bible to Edward.

Suddenly someone rushed across the airport, someone I knew and recognized.


The worst enemy of the Christians. He was known for hunting Christians down, reporting them to the authorities, and worse. I knew someday God would bring him to justice, but right now I was terrified and thinking that day would never come.

“Don’t let her get away!” Amir shouted. “She’s carrying a Bible!”

Immediately the inspector officer rushed after me and caught hold of me. Amir stood by, smirking.

“Explain yourself,” the officer demanded.

“I have nothing to explain,” I said, “except I’m doing the will of my Father in Heaven.”

I looked up and our eyes met, mine boring into Amir’s. Right then and there I knew he was sorry he’d betrayed me.

Standing Up to the YA Fantasy Impuritans

As Christians and as fantasy fiction fans, we have a duty to stand up to bullies, including the “Impuritans.”
| Feb 8, 2019 | 38 comments |

You have probably heard by now about Amelie Wen Zhao, the Chinese immigrant who pulled her YA fantasy nove, Blood Heir, after being set upon by Twitter piranha.

Zhao based the invented world in her novel on her own experience growing up on mainland China. In China today, slavery is a concern, especially for young women, who are in danger of being kidnapped and sold to men who cannot otherwise find wives, due to China’s one-child policy. So Zhao included indentured servants and human trafficking as a plot issue in her novel.

Only, in her fantasy world, it was magic powers, rather than skin color, that fueled the discrimination that decided who ended up as a slave.

It was this that—of all things—that upset her attackers.

Nearly every fantasy or science fiction book I read as a child had basically this same theme—that prejudice would be different in an alien culture, and by viewing it from afar, we can learn to overcome it in ourselves. And yet, this very premise is what Zhao’s attackers denied. They condemned her for allowing slavery to be about anything but skin color.

They actually said this.

Other attacks

Zhao is not the only author to be so attacked recently. Laurie Forrest and Keira Drake both suffered similarly before the release of their books. The publicity from the media reaction catapulted Forrest’s book, The Black Witch, to greater success, but Drake was not so lucky. She delayed her book, The Continent, rewriting sections, but she did not benefit from the publicity and her series is struggling.

All three of these authors were attacked for writing the very kind of books that were most praised only a few years ago.

Speculative fiction without speculation?

Speculative fiction is the art of speculating about the world through fiction. How can such an art exist, if no one is allowed to write about anything  except exactly what they know from their every day experience?

Science fiction’s grand master, Gene Wolfe, addressed this subject when he wrote:

Science fiction’s fictional people are hard to make believable because they are likely to be remote from the writer’s experience. Who has known a Martian? A starship captain? A woman who has published scientific articles intended to prove that she is not a human being? If the writer cannot empathize with people who do not yet exist—and may never exist—he must stay out of science fiction.

His comments remain true today. Without empathy for others—the ability to imagine the life and experience of someone unlike ourselves—we cannot enjoy speculative fiction.

Hitting close to home

As an author, who is also the mother of a Chinese girl, this story hit me particularly hard. I immediately ordered Blood Heir on Amazon, hoping that a show of support from the public might convince Zhao to change her mind about canceling the book. Alas, I have since received word from Amazon that the book has been pulled.

Blood Heir, Amelie Wen ZhaoZhao’s story is doubly painful, because I, too, spent decades pursuing my dream before I was finally published by Tor in 2009. So Zhao’s comments on the topic from her blog broke my heart.

On a recent Skype session with my parents, my mother told me in tears that, when I was around 8 years old, I said to her one day: “Mama, I want to be an author!” And she gently sat me down and told me the reality. That so few authors make it — and fewer, still, make it big. That many still struggle on in pursuit of their dream. That I have to decide whether I want a life of comfort — one that my parents have gifted me — or a life of uncertainty, potential financial duress, and, very possibly, never having my books see the day of light.

I chose. For my entire life, I’ve prepared myself for a career in finance, telling myself it was the more realistic choice, that success stories for authors came true once in a blue moon and that dreams were something only Cinderella’s fairy godmother could grant with a wave of her wand.


This young woman’s life dream has been robbed by bullies.

The Impuritans

These modern bullies form mobs that exhibit as much moral outrage as the Victorians or Puritans of old, but they lack the one thing that redeemed the older groups: virtue.

The Victorians and the Puritans may be known for moralizing, but many of their members legitimately tried to live up to the high moral standards they proposed. One might say that they had the virtues of their vices. This new movement has all of their arrogance but none of their morality.

Because of this, some have started referring to these frothing, outrage mobs as Impuritans. Where the Puritans used peer pressure in an attempt to enforce morality, these modern Impuritans attempt to bully people into accepting sinful behaviors.

A Christian’s duty

As a writer and a mother, this story appalls me, but as a Christian, our duty must go beyond merely being appalled.

As Christians, we have a duty to stand up to bullies, especially if they are urging us to commit sins and accept false, non-Christian moral codes. In the Bible, the penalty for yielding to bullies was surprisingly severe. Upon leaving Egypt, the Israelites had been told that they would be led to a Promised Land, running with milk and honey. Moses sent a few ahead to spy out what lay ahead. What they discovered was a land running with milk and honey, but the people living there looked menacing. The spies feared the locals much as we might fear standing up to a bully.

The spies returned and told the Hebrews that the land was full of unbeatable giants. Only one told the truth about what he had seen, a man named Caleb, but the people did not listen to Caleb. They quailed in fear and begged not to have to face these giants.

God’s response? He condemned the entire tribe to wander in the desert for forty years, until the current generation of adults had died. Those who had given into their fear were denied entrance to the Promised Land. When they finally were allowed to enter,  Caleb, the one who told the truth, was still as strong, at 85, as he had been—the gift God gave him for his truthfulness.

Standing firm

If we modern Christians give way to this mob mentality of immorality and outrage, rather than standing up to those who abuse the truth, we could lose our promised land. America has been a promised land in many ways—a place of freedom and human dignity. These benefits have been vanishing in recent years, not because some tyrant has taken them from us with bayonets, but because we are ceding the willingly, due to the insistence of the Impuritans.

Amelie Wen Zhao has had her promised land, the happy future she had envisioned since she was eight years old, snatched from her. If we continue to allow this to happen, we, too, may find that we have lost ours.

We must take a stand against immoral mob mentality if we want to be able to continue to practice Christianity, much less enjoy speculative fiction, in the years to come.

Speculative Fiction Writers Guide to War, part 17: War Costs: Food per Fighter

If you ever wanted to calculate how many supplies your fictional army needs, your numbers start with how much food per single war fighter per day. We’ve got the numbers here–for both humans and non-humans!

Travis P here. Since Travis C did an excellent job giving an overview of the costs of war essential to providing for a military, I think it’s time to give the math-lovers out there some hard data that can actually be used in formulas to make generate specific data on what an army might need, starting with the most basic possible cost of war–the cost of putting food in the bellies of war fighters. Which starts with a look at how much food per day a war fighter needs. You as a writer may never need these resources, but if you ever do, we’ve compiled some data to indicate just how much food it takes to keep an army fighting in the field. (Note this post wound up being longer than normal, but I’ve used bold text to highlight key ideas for those who will skim this article rather than read every word.)

The place to start with this kind of analysis is based on historical data, what real world armies have already done and then to expand from there to discussion of imaginary armies composed of fighters who are literally not of this world. We’ll also in future installments cover some of the issues regarding what it takes for a nation to produce sufficient food, which relates to the transportation of food and other supplies. Which will segue nicely into future posts that will provide some formulas that relate to transportation (and more).

How Much Food Per Human War Fighter

The first numerical summary I’ll share here of how much food an army needed per day was from the records of the Colonial Army prior to US independence from Great Britain (1775). What they listed as their daily needs surprised me in its last item (source, a US Army Quartermaster piece entitled The History of Rations):

Credit: Savoring the

l6 oz. beef  (probably salted)(about 1100 calories) (193 grams)

18 oz. flour  (about 900 calories) (510 grams)         

1.4 oz. rice  (about 150 calories) (40 grams)

16 oz. milk   (about 300 calories) (454 grams)

1 qt. spruce beer (about 450 calories) (907 grams/ml)

Total: roughly 3,000 calories per day (caloric value of food varies according to exact type, which is partially unknown), weighing 5 pounds 10 ounces or 2.56 kilograms. While the beef, flour, rice, and beer could be stored over a long period of time, the milk would have to have come from fresh-milked cows, due to a lack of refrigeration at that time.

Note that the members of the Colonial Army often enough did not receive this much food. But this list, even though a bit idealized, took into account the higher calories a person needs when marching from battlefield to battlefield, a number significantly higher than the roughly 2000 calories per person that’s considered an ordinary caloric intake in our time. The variety of food reflects a rudimentary understanding of nutrition–spruce beer, made from a brew that included fresh spruce tree needles, was intended to prevent scurvy (which it did because the needles added a certain amount of Vitamin C to the beer). (Spruce beer was the surprise item on this list, because I’d never heard of it before!)

Note also that the average size of a Colonial soldier was less than a modern American–and smaller people on average require fewer calories. A modern US Army MRE (Meal Ready to Eat) has approximately 1250 calories, so three per day would equal 3750 calories, which is a more appropriate calorie count for larger people. More on MREs and calories per size a bit later.

To further illustrate the issue of people needing a different number of calories in accordance with the work they perform, let’s look at the German rationing system for food during WWII (cited in the Wikipedia article Garrison Ration).

The Germans used 4 different levels of allotments for food, based on how hard they perceived a person was working and how much food they needed. Note this system was based on a number of scientific measurements. The food supplied was specific to what Germany was able to produce, but it covered all nutritional needs for their military well–even at the lowest calorie level, these were not starvation rations (sadly the Germans applied starvation rations elsewhere).

Ration I (Verpflegungssatz I) was for troops committed to combat, for those that are recuperating from combat, and for troops stationed in Norway north of 66° N. Latitude (because living in extreme cold requires a higher caloric intake).
Ration II (Verpflegungssatz II) was for occupation and line-of-communication troops.
Ration III (Verpflegungssatz III) was for garrison troops within Germany.
Ration IV (Verpflegungssatz IV) went to military office workers and nurses within Germany.

(Note under some circumstances, such as a soldier being very large, or extreme cases of long marches, the calorie intakes listed would be insufficient–but the system did work for most people under most circumstances.)

More ancient sources that list rations are, not surprisingly, not as nutritionally balanced. According to the online source Alimentarium, during the time of the early Roman Empire, each Roman soldier was allotted 2 Roman pounds (1 pound 5 oz or 657.8 grams) per day of bread, plus an unknown amount of meat, olive oil, and sour wine. Salt and the kinds of fruits that would stave off scurvy are not included in this daily ration at all. Though we should note that Roman soldiers ate fruits when available. (Romans always ate from local cuisine in addition to what they were rationed.)

The Romans would march with cows and wagons full of bacon, grain, olive oil, and sour wine as part of their baggage train. An individual soldier might carry some hard biscuits, bacon, and sour wine on his person, but most of the food was provided for the entire army at once, based to a large extent on what the local civilian economy supplied. Which was to a certain extent how all ancient and many medieval armies operated. Food supply was for the entire army, not really for soldiers as individuals. Without cooks (almost always civilians until WWI) to process the food, the army would go hungry.

The reason this was true was because of spoilage. Fresh food doesn’t usually keep for very long but live animals obviously don’t normally get eaten by bacteria due to their own immune systems (fresh milk will clearly not keep long, but if you keep the milk cows with you, you can provide fresh milk on a continual basis). Certain foods like grain or flour resist bacteria because they are dry. Dry cheeses also resist bacteria and have been used to supply some ancient and medieval armies (olive oil, while not dry, contains no water and as a result resists bacteria). Alcohol also resists bacteria and was for a long time in various forms part of the supply ration for many militaries (a ration of rum was common for colonial-era navies–a ration of whiskey was allotted to the men of the Lewis and Clark expedition).

Another advantage of alcohol as food supply is that some types, such as beer and wine, have water within them, which means they can help supply the body’s need for hydration. Whiskey and rum cannot do that effectively on their own, but when mixed with water, they serve as a purifier for water, since many ancient water sources were contaminated with bacteria or other microorganisms that alcohol kills. (While this article is barely touching on the issue of hydration, please note that military operations requiring a lot of marching may require on average about 6 liters, or 6 quarts, of water or other liquid containing water, per day.)

Pastoral nomad warriors of the past, who were able to sustain themselves off their herds, would simply drive the herd with them if going into a battle that would take a long time (and leave the herd in a safe place if going on a raid). Though of course the professional armies in world history have been supported by sedentary agricultural production. Since most agricultural nations have primarily produced grain (whether that be wheat, barely, oats, rice, or corn/maize) and secondarily livestock along with the fact that grain at least needs to be boiled in water if not baked into bread to be edible, while livestock needs to be slaughtered, butchered, and cooked to be edible, that meant that soldiers mostly could not carry their own food on their person. They were either dependent on what they could obtain from the civilian economy (which, especially if they were invading enemy territory, probably meant stealing from civilians) or soldiers required an entire army camp apparatus to provide their food. Or some of both.

Since it’s possible for soldiers to be cut off from the field kitchen feeding them or it may be necessary for them to spend extended periods of time away from such a kitchen in a combat operation (this can happen to sailors, too, but is not nearly as common at sea), militaries over time have worked to make rations more compact and easier to carry on a person in combat. An early step in this direction came in the late Eastern Roman Empire, a.k.a the Byzantine Empire, which eventually changed its philosophy on supply (along with the introduction of the Theme system). Each individual soldier was required to supply himself with 20 days of food, usually in the form of grain. The Byzantines carried a paximadion, a hand mill, to grind their own grain to make a rough bread that was their primary sustenance in battle, a bread the soldiers would make themselves, providing them a measure of independence in food supply that didn’t exist for most armies of their time.

It wasn’t until World War I that it became possible to feed a soldier a complete set of rations while separated from a field kitchen. That’s because of the invention of canning (“tinning” in the UK) allowed food of sufficient nutritional value to be stored in a way that would keep it safe from spoilage.  World War II also used canned (tinned) foods for soldiers who could not easily be fed in field kitchens.

Freeze dried food. Credit: Backdoor survival

Post-World War II, the practice of freeze-drying food, which actually had been pioneered by the Incas in South America (circa the 1400s), provided the most compact form of food currently known. With freeze-dried food, it’s possible to carry 3000-4000 calories per day at a weight of only 1.5 to 2 pounds per day (680 – 907 grams). (Of course you still have to add water.)

While freeze-dried food is the most compact form of food in common use, many militaries have moved away from using it, because freeze-dried food isn’t particularly tasty and in wartime, the supply of water isn’t guaranteed and may have to be carried by soldiers–so you might as well include the water in the food in the first place. In fact, the infamous US Army ration of modern times, the “Meal Ready to Eat,” (MRE) is “ready” because it ISN’T freeze-dried (though some early versions of MRE’s included some freeze-dried food, none do now).

Generally, a MRE contains the following items (from


  • Entree – the main course, such as spaghetti or beef stew

  • Side dish – rice, corn, fruit, or mashed potatoes, etc.

  • Cracker or bread

  • Spread – peanut butter, jelly, or cheese spread

  • Dessert – cookies or pound cakes

  • Candy – M&Ms, Skittles, or Tootsie Rolls

  • Beverages – Gatorade-like mixes, cocoa, dairy shakes, coffee, tea

  • Hot sauce or seasoning – in some MREs

  • Flameless Ration Heater – to heat the entree

  • Accessories – spoon, matches, creamer, sugar, salt, chewing gum, toilet paper, etc.

Each MRE provides an average of 1,250 calories (13 percent protein, 36 percent fat, and 51 percent carbohydrates) and one-third of the Military Recommended Daily Allowance of vitamins and minerals.
Each MRE weighs between 18 and 26 ounces depending on the specific meal (510 to 740 grams), so an entire day’s provisions would weigh between 3 pounds 6 ounces (1.53 kg) and 4 pounds 14 ounces (2.22 kg). Which is heavier than freeze-dried food, but not a great deal and they are easier to consume.

Futuristic food is not likely to get any more efficient than freeze-dried/MRE-style meals. Star Trek fans may cite the replicator at this point–which can transform energy, which in theory weighs nothing, into food. This would seem to be the ultimate way of making food lightweight, right? Of course, speculative fiction authors are of course free to invent what they want; however, you should be aware that a food replicator is an unrealistic type of technology.

Directly transferring energy into food (Star Trek replicator style) would use a lot of energy. More than you might imagine–that is, if a replicator is truly thought of as directly converting energy into food. That process would be covered by the formula E=MC^2, or to flip that around for creating mass, M=E/C^2. Since “C” is the speed of light and that’s about 300,000 kilometers per second (186,000 miles/sec) that means C^2 is “only” roughly 90,000,000,000,000,000 (9×10^16). Which means if you decide to make 1 kilogram worth of spruce beer in your replicator (because you’re curious what it would taste like) (one kilogram, by the way, is about what the US Colonial ration of one quart of spruce beer would weigh), assuming 100% efficiency of the energy to matter transfer, it would take you a mere 90,000,000,000 megawatts to produce that one kilogram of spruce beer. And since by one online source, the entire United States uses about 317,000,000 megawatts per month, it would only take a “mere” 23 years 8 months of all the electric production of the entire United States (as it currently is) to produce enough power to quench your curiosity about what spruce beer tastes like.

Yeah, I don’t see energy-to-matter food replicators happening. Not ever–even if a future society mastered the technology, it seems incredibly wasteful. That’s the kind of thing you’d save for rare engine parts made of out platinum or whatever other very rare mineral. You wouldn’t waste such a technology on food production. Even an advanced food generator that would allow you to replace cooks would make more sense if it used actual matter that’s already around instead of generating it directly from energy. Why not have a kind of advanced digital printer for a replicator instead, that could squirt together food components from a bank of proteins, fats, sugars, starches, and liquids to make your custom food? Much more practical! Though maybe not as tasty…but note that while this sort of technology would allow you to replace field kitchens, it would do nothing to make field rations any smaller.

So any realistic version of a future society will include them needing to pack and supply field rations as much as past ones have done. (In fact, even Star Trek itself at various times references the existence of field rations!)

Of course a story set in a fantasy world can have magical rations. The Lord of the RIngs features Lembas Bread, a bread baked by elves (no, not Keebler elves! 😉 ) that tastes sweet and when in use, one small loaf will provide enough energy for one person for an entire day. The exact weight of a Lembas loaf is unknown, but it does weigh something. Let’s estimate half a pound (227 grams) per Lembas loaf–that means Lembas Bread at maximum is only about 4 times more efficient than freeze-dried food. Though Lembas may have the additional benefit of reducing thirst, note that even an army of elves would have to think about how much Lembas they need versus how much they can carry–and for a long campaign, even magical bread would require wagons of some kind to move it.

And of course one would have to consider the resources required to make Lembas or other magical food. Please understand I’m not saying good worldbuilding requires you to calculate all of these things out in every case. But nothing should be free in a story world. Not even magic. You should consider the fact that an army marching to war, even a magical army, will need to plan how it’s going to feed itself when you create your story world. (Of course, spells that generate food from non-food–say rocks into bread–could be one way to solve this issue.)

Food Per Non-Human War Fighter

Ok, we’ve talked about the amount of food a human warrior has needed and various means to supply it. But what if we don’t want to write humans? How much food will a non-human need?

While androids/robots may sustain themselves with mostly energy and a small supply of replacement parts (including replacement hydraulic or lubricating fluid if applicable) and while we can imagine more exotic aliens who perhaps lay out in the sun to gain energy from photosynthesis or magical creatures who derive energy from proximity to crystals or similar notions, these kinds of creatures will be the exception in most stories.Because most inhabitants of speculative fiction stories will need to eat food, just like we do. And while some aliens/magical creatures might be able to consume food humans would get no nutritional value out of, it’s generally useful to think of these beings as eating food the way we do, but needing different amounts.

There are two basic factors that influence how much food a creature needs to survive. The first is metabolic rate, i.e. how much a creature burns per hour at rest. The second is size, with larger creatures needing more food in general than small ones. With the important caveat that larger creatures almost always have lower metabolic rates than smaller ones, so while an elephant may need much more food than a mouse, each bit of tissue in the mouse is actually using far more energy per period of time than the same amount of elephant tissue. While it is true that an elephant eats much more food than a mouse, in proportion to its weight, a mouse burns more calories in proportion to its body weight than an elephant, nearly 12 times as much. So however many mice it would take to weigh as much as an elephant, that number would eat far more than an elephant does!

As explained in an article by Khan Academy, our planet has two kinds of creatures, endothermic (they produce their own heat) and ectothermic (their body temperature matches their surroundings). Birds and mammals are endotherms and pretty much everything else is an ectotherm (note most but not all dinosaurs are now considered to have been endotherms).

Lizardmen vs. Chaos. Credit: Warhammer Wiki

Ectotherms: A pure ectotherm’s metabolism is defined as a Standard Metabolic Rate (SMR)–and the thing is that this rate changes with temperature. So the SMR of any cold-blooded (ectothermic) creature is like an algebraic variable that has a different range for every species–a range and not a fixed value. When it’s colder outside an ectotherm moves slower and uses less calories. When it’s warmer, an ectotherm moves faster and uses more calories. Since an ectotherm is not using its own energy to raise or lower its internal body temperature, it uses much less energy overall than an endotherm, at times as little as 10% of an endotherm’s energy needs. So your army of lizard men can probably skip their breakfast…and carry far fewer supplies…but they are gonna march super slooooow in the morning…though they might get hungry in the afternoon after a quicker pace marching in warm sunlight.

Since the baseline food consumption of an ectotherm is a variable by temperature (not to mention activity), it will be difficult to account for it fully in this post. To provide some means to account for the effect of size alone on ectotherm metabolism, I’ll make reference to an academic paper that says the relationship of size of crocodiles to its SMR is SMR = 1.01 M^0.829 at the standard temperature of 30°C (86°F) (where M=equals weight in kilograms). For many readers this equation will not be meaningful. The following diagram will be better:

An unfortunate thing about this chart is it measures metabolism in oxygen consumption per minute. It’s possible to convert that to calories but the conversion factor itself is, in truth, a variable. But about 5 calories (we’re talking “calories” as the term is discussed with food and diet, which are actually “kilocalories” in scientific talk) equal one liter of oxygen consumed. But a really big crocodile weighing around 300 kg / 660 lb. uses about 1/10 liter of oxygen in a minute. Which means in ten minutes it burns 1 liter or uses 5 calories energy or 30 cal per hour. That means in a day, doing absolutely nothing, a big (300 kg) crocodile needs 720 calories to stay alive (at 30 degrees C). Since it can get that much from around 300 grams of meat (10.5 ounces), the food needs of any ectotherm/reptilian are very, very low as long as they aren’t doing anything (and are significantly lower when it’s colder outside!).

To get a handle on how much temperature affects ectotherm metabolism, let me include a chart from The Biology Place. The chart applies to a specific organism, but shows the general trend for ectotherms to use more energy with higher temperature up to a certain point, above which high temperature causes the ectotherm to begin to shut down–and need to cool off. Note that at 40°C (104°F) an ectotherm uses twice as much resting energy as at 30 C (86°F), but that at 10°C (50°F) it uses only 25% of the energy at 30°C…so our crocodile from above only needs about a measly 180 calories per day to stay alive at 10 C/50 F. This probably would also be true for reptilian humanoids, if such a thing were to actually exist. They can’t warm themselves, but their need for food when their activity is minimal is very, very low! (Of course, when actively moving over an extended period, they need to eat much more.)

Endotherms: Calculating the food needs of an endotherm is actually somewhat easier. An endotherm has a Basal Metabolic Rate (BMR) that reflects the basic amount of energy it needs to regulate its body temperature. That means, laying around, doing nothing, an endotherm burns a certain minimum amount of calories just to stay warm. That number of calories can be thought of as a fixed minimum number per species, though it increases per muscle mass of an individual (which is why human men, who usually have more muscle mass than women, burn more calories per day). 

Note that while this post will not provide a specific formula to track it, it’s true that the BMR is higher for creatures prone to heat loss by living in a cold climate (including humans needing more calories in a cold zone than a warm one). As one scholarly article said, “All other things being equal, a polar mammal living at −10°C has a body temperature ∼2·7°C warmer and a BMR higher by ∼40% than a tropical mammal of similar size living at 25°C.” Polar land animals would have to eat 40% more (in their environment).

Likewise, you may not realize it, but living in water causes sea mammals to lose heat much faster than land mammals. While fat under the skin helps slow their heat loss, the BMR of any given sea mammal is much higher than a land mammal of the same size. One study showed at least some species of dolphins weighing around 1oo kg/220 lbs to use about 1 liter per minute of oxygen when resting.  Since there are 1,440 minutes in a day, times our rough conversion factor of 1 liter of breathed O2 equaling 5 calories, that means a dolphin of that size (100 kg) and species needs 7,200 calories per day just to stay warm–ten times as much food as a 300 kg crocodile at 30 degrees C. Note a 100 kg human male at rest uses about 2,500 calories a day–a dolphin of the same size to stay warm in water uses nearly three times as much energy and so needs to eat three times as much food. (Merpeople would need to eat a lot!)

While scientific studies note a relationship between a creature’s internal body temperature and its base metabolism–a higher body temperature indicates a higher metabolism–usually this factor is something scientists ignore. They often calculate typical BMR based on the mass of a creature alone, as this generally accounts for observed caloric intake needs. Roughly speaking, though there are variations among orders of mammals and birds (the most important variation being sea mammals and extreme cold weather mammals as already noted, but it’s also true that creatures with bigger brains burn more calories at rest than smaller animals), it’s generally true that the BMRM^0.75 (where mass equals weight in kilograms–for small mammals and birds this number is more like BMR = M^0.67).

What that math relationship looks like on a chart I’ll show you from an article taken from the Journal of Experimental Biology: Note that the bottom of the chart tracks mammals while hibernating or “torpid”–i.e. many mammals can enter a state where their metabolic rate plunges and they use far less calories than normal (when they are “entheric,” as the chart puts it).

An important point to remember on the subject of calculating how much a mammal (or likewise an alien or demi-human) needs to eat is that having to work can greatly increase the amount of calories a living creature will need, beyond the BMR. Human beings rarely double our BMR (the BMR for an average sized American woman is estimated at 1,400 per day and 1,800 for the “average” man), yet for most living creatures who live in the wild, doubling their BMR is the minimum they do on a daily basis. Some animals use up to six times their BMR when active (to give one example, while a dolphin may need roughly 7,000-8,000 calories per day resting, they on average need up to 33,000 calories per day in the wild!) Whether your non-human species typically does between 1.5 and 2 times BMR like a human or 4 to 5 times BMR like a dolphin has to do with how active your species is–if they are using 4 to 5 times as much energy as their BMR, they would pretty much be moving constantly, like dolphins do.

Ok, I’ve given a lot of data here as resources. It may not be immediately clear how to apply this data to world building, but Travis C is going to step in next week to help you put it all together. 🙂

Travis C here. I’ve watched Travis P develop this section through the week, building in detail upon detail of good stuff! Rather than pile on more this week, our next installment will work through an example using Travis P’s research and some of my own to show how a story might evolve via each of our Cost of War considerations.

Stay tuned next week as I unpack Lady Katie’s war against the Mad King Crabcakes as she fields a fantasy army!

Are All Fandoms Created Equal?

How are sports and fictional fandoms alike? How are they different?
| Feb 6, 2019 | 1 comment |

There is a particular meme that always shows up twice during the year. You can see the meme below, where Spock is pondering the logical fallacy of looking down on sci-fi/fantasy conventions and cosplay while bearing less ill will to the equally silly/awesome/childish/dedicated/what-have-you devotion of football fans to their respective teams. This meme always makes the rounds when football season kicks off in late August and shows up again during the NFL playoffs, intensifying right around the Super Bowl. This is obviously a sore subject for many people on both sides, but since I’m not firmly rooted in either one, I’ll just throw my two cents out there.

I don’t consider myself an “avid” fan of anything. There are some fictional realms that I really enjoy, as well as some sports that I watch regularly. Yet I’ve never been to a convention and I don’t own any figurines, comics, or collectibles. I did see all three LOTR movies on opening night and numerous times afterwards (the movie tallying scene in Clerks 2 was a hoot) and I know a fair amount about Star Trek, though I can’t say that Star Wars holds my attention for long. I’ve been to a number of sports games but I have never been to a professional football game, and although I am a long-suffering fan of my hometown Atlanta Falcons, I don’t own any memorabilia or jerseys. I do watch football whenever it is on TV and I’ve been getting embarrassed in my neighborhood fantasy football league for a couple of years now. I know a good bit about the game, as well as baseball and basketball. However, I don’t live for these sports, just as I don’t “geek out” whenever a new Star Wars or Harry Potterverse movie trailer drops.

So now you know my (lack of) geek or sports cred, let’s examine the meme at hand. First, are these two fandoms anything alike? What do they share in common? Well, the fans spend exorbitant amounts of money on all manner of entertainment and merchandise related to their particular fandom. They wear uniforms to identify with their tribes. People who “don’t get it” think they’re weird. Their significant others are tired of competing against the fandom for affection. And no matter what you say or do or think, you’ll never convince them that your fandom is better than theirs.

How are sports and scifi/fantasy fandoms different? I suppose the biggest difference would be that one is based in reality while another is not. I don’t mean this to be derogatory, but this is a simple fact. Everything that sports fans idolize and cheer for are done by real people in the real world. Their “superheroes” don’t save the world or stop evil villains (at least, not in the traditional sense) but they fight against physics, physiology, psychology, age, the environment, and most importantly, other people who are very similar to them and who want the same thing. Fictional fandoms are based entirely on imaginary people, creatures, and worlds, and while they may be as complicated or perhaps even more so than our reality, there are far less limits in these realms.

This is where I have to disagree with Mr. Spock. If you ask a sports fan why he or she is wearing the jersey of their favorite player and the fan responded, “Because he is so AWESOME! He can jump over mountains and lift three tons and run a forty in two seconds and he never needs to sleep and he eats twenty steaks a day!”, people would probably back away slowly. Yet these characteristics would not be out of place at all at a superhero convention where people dress up as Superman or the Flash or Captain Marvel. Now, wearing a jersey or a costume imparts no powers nor brings the wearer any closer to their idol, but there is something to be said for idolizing reality rather than fantasy. You CAN meet your real-life sports hero. You CAN directly benefit from their community charity. You CAN possibly even play with or against them someday. However, the closest we’ll ever get to meeting a real-life superhero is shaking hands with the actor or actress who portrays them on screen.

Yet this speaks to the power of imagination. Superman isn’t a real person, but the idea of Superman has inspired millions and has helped many people through difficult times, as well as spawned countless livelihoods. Removing Spider-Man from the world would leave a bigger hole than if Tom Brady was suddenly erased (did I say that out loud?). So while cosplay and fantasy conventions are certainly more “nerdy” than sports, they are no more and no less stupid. It’s all what we make of it.

What a great contest our 2019 Winter Writing Contest is. We’ve had wonderful entries—a considerable number which received double-digit thumbs up! Now it’s time to announce our finalists!

Just a reminder. This is NOT a popularity contest. We really do want to acknowledge writers who have honed their skills and demonstrated their ability in this little exercise. So, those who vote in the poll, please be sure you read all three of the finalist entries and give a fair assessment.

Special thanks to all who entered and all who gave their feedback in the preliminary round. We had some that came so close to making the finals—it was hard for me to follow the rules for the contest and include only three in this poll.

We’ve also had a number of excellent, helpful comments, so hopefully you all who entered gained some insight into your writing. I hope the challenge has encouraged and inspired all the writers.

So here, in alphabetical order by last name, are your 2019 Spec Faith Winter Writing Challenge finalists:

  • Sarah Daffy
  • Jay DiNitto
  • L. G. McCary.

All that’s left is to select the winner, and that’s also in the hands of our visitors. Choose from these finalists and vote in the poll at the end of this post for the one entry you think is best.

The entry receiving the most votes will be the winner, and the author will receive a $25 e-gift card from either Amazon or B&N. (In case of a tie, I’ll draw for the winner).

Voting will last until midnight (Pacific time), Sunday, February 10.

And now the finalists’ entries:

The guard would never let me enter if he knew what I was planning.

The airport inspector and guard would never let me enter if he knew what I was planning—and hiding.

Right now I was being screened such at customs, for metals or explosive devices. What the airport inspector didn’t know was that a Bible was stashed away in the false bottom of my carry-on bag.

In this country it was illegal to import Bibles. It was illegal to be a Christian. It was even illegal to own a Bible. That’s why I was helping my friend Edward smuggle Bibles.

I held my breath as the airport inspector looked me over, hoping and praying he wouldn’t find me out. Or my secret. He patted me down and used his metal detector. Nothing. No metal, no explosive devices, nothing. He grunted.

“Go ahead, ma’am,” he said. “You’ve got nothing illegal on you.”

I smiled and moved ahead. I was through all customs, all inspectors, now all I had to do was figure out a plan and get the Bible to Edward.

Suddenly someone rushed across the airport, someone I knew and recognized.


The worst enemy of the Christians. He was known for hunting Christians down, reporting them to the authorities, and worse. I knew someday God would bring him to justice, but right now I was terrified and thinking that day would never come.

“Don’t let her get away!” Amir shouted. “She’s carrying a Bible!”

Immediately the inspector officer rushed after me and caught hold of me. Amir stood by, smirking.

“Explain yourself,” the officer demanded.

“I have nothing to explain,” I said, “except I’m doing the will of my Father in Heaven.”

I looked up and our eyes met, mine boring into Amir’s. Right then and there I knew he was sorry he’d betrayed me.

The guard would never let me enter if he knew what I was planning.

That’s precisely why I told him my intentions.

“Eye’m going t’sh-to steal,” I, in my drunken rake’s disguise, declared with exaggerated slur, “that thing, right there. Thank you v’ry much!”

It worked! Lisette heard my final words, our predetermined cue. A small section of the floor molding rose, on the far side of the display room, revealing the narrow passageway. A mechanic’s creeper then glided out on well-oiled casters.

I unsteadily pointed at my target: the telluric electronal harvester, humming quietly behind the guard. It burnished bright with newly manufactured metallic curves and subtle, decorative illuminations. Naturally, it levitated, needlessly; my brother was ostentatious with “his” inventions as they were display at our annual Von Barger Estate Fair.

Lisette—my blessed, willing, diminutive, long-suffering, task-runner—slid out from the darkness of the hidden room. Brother’s architectural cleverness was my opportunity.

“You d’serve a dance, my friend!” I announced to the guard, and ersatz step shook my limbs.

Lisette lithely slid onto the creeper and wheeled underneath the harvester, deactivated the correct section of casing to reveal the electronal hopper and its wiring, quickly sketched out my proprietary schematics, and slid back into the passageway in just under a minute.

“Thank ye v’ry much fer yer time, sir!”

I belched, produced a silver ducat from my pockets, and flipped it over to the guard. It fell lamely onto the carpet in front of him. I doffed my hat and left down the hall, among the other fair-goers.

By this time tomorrow, the other Von Barger son will receive a very obnoxious series of tele-scripts and sketches that revealed my successful little reconnaissance and recovery mission. Our little prank war continues!

The guard would never let me enter if he knew what I was planning.

I glanced at the hallway behind me. The research wing of the Library of Congress wasn’t as pretty as the reading room.

I smiled and opened my backpack.

“Check-in is on the left,” he said, poking in my bag with a plastic baton. “Sign in and leave your ID. You’ll have to throw that out.” He pointed at the box of cheese crackers.

“I just bought it!” I whined.

He rolled his eyes. “Don’t open it and leave it in your bag.”

The receptionist at check-in was barely paying attention. I handed her the fake ID, deposited my backpack in the locker, and sat in the cubicle with the only blind spot in the room. The flattened cracker box concealed in my hoodie poked my ribs.

The book came protected in a white archival box. It was smaller than I expected. I caught my breath as I opened it with white-gloved hands. Despite its size, it felt heavy, as if history added weight to its pages. I could barely believe I held the diary of the daughter of the most famous psychologist in history. She had written her name on the inside cover in spidery ink: Anna Freud.

I turned the fragile pages to the day I was looking for. It was blank but for one phrase.

Gestern festgenommen. “Arrested yesterday.”

I couldn’t believe I was holding what the Gestapo were so desperate to find. The diary fit perfectly in the cracker box. The receptionist was clearly woozy from handling my ID card and handed me my backpack without a word. She would be snoring in moments.

The ancient bottle of reagent was waiting in my hotel room to reveal what was inscribed on the rest of that blank page. Now I had to make it out the door.
