Co-Geeking

If you’re building an army to conquer the pre-modern world (or a fantasy world something like it), you might be tempted to include war elephants. At first glance, they seem like a great idea. Elephants are large, thick-skinned, strong, and intelligent, with long tusks and powerful trunks. Including them in your army is about as close as the real world gets to having dragons on your side. Well, I’m here to tell you that in most cases, they’re actually not such a great idea. (There are a few exceptions; I’ll get back to those later.)

Not all elephants are trainable. Three species of elephants survive in today’s world: Asian, African bush, and African forest. Asian elephants can be trained, but the African bush and forest elephants cannot. Several other species and/or subspecies of elephants once existed in various parts of Africa and Asia, but they went extinct in antiquity as a result of hunting and habitat loss. Elephants susceptible to domestication have historically been used in North Africa and Southeast Asia for labor, transport, and war.

Elephants do have their uses in war. They have been used as mobile platforms for archers and light artillery. They can also trample and gore enemy soldiers, and use their strength to help demolish the defenses of towns and fortresses under siege. Horses who have not been trained with elephants will not go near them, so war elephants can be good for disrupting enemy cavalry. Off the battlefield, they are good for carrying or dragging supplies and heavy pieces of baggage like siege weapons. Despite these uses, there are a number of serious problems with using elephants in combat.

We may as well start with the moral problem. Elephants do not breed well in captivity, and so most elephants used for labor or war must be captured as calves from the wild and trained into obedience, often using quite brutal methods. It goes without saying that this is a terrible thing to do to any creature, let alone such an intelligent and social animal, but if you’re already building an army for world domination, I assume you’re beyond such niceties as moral scruples, so let’s move on to the practical problems.

One big problem is that elephants are not naturally combative. Apart from males competing for mates, mothers defending their young, and occasional rogue elephants behaving abnormally, an elephant is much more likely to run away from danger than toward it. It takes extensive training to get an elephant to withstand the chaos of a battlefield, and even then it was a common practice in the past to feed war elephants fermented fruit to get them drunk before battle. Getting elephants drunk helps keep them aggressive, but it also makes them harder to control. There is a real risk that a sober elephant facing the clamor and commotion of a battle will turn and run away, or that a drunk one will ignore its driver’s commands and simply go on a rampage. Now, I know what you’re thinking—drunk rampaging elephants sound like an awesome weapon to unleash on your foes, but keep in mind that around half the soldiers on an average battlefield are going to be your own, and there’s no way to be sure that an out of control elephant will do more harm to your opponents than to you.

Another problem with war elephants is the cost. Elephants in the wild may eat up to 300 kilograms of forage per day. In captivity, eating a richer diet, elephants consume around 50 kg of grain and vegetables per day, more if they are doing heavy work. That amounts to at least 18,250 kg per year. Pre-industrial agricultural yields could vary widely with region, climate, and farming techniques, but at best you could expect around 500 kg of grain per hectare of farmland per year. That means you’d need about 36 hectares of land dedicated to feeding just one elephant. 1 square kilometer of farmland could, under the very best conditions, just barely maintain three elephants. If you have a big enough empire with a strong enough agrarian economy, this may sound like it’s worth it, but consider the opportunity cost. The same farmland could also support 100 soldiers for a year, who can be trained in any number of specializations, will (hopefully) not get drunk and turn on your own troops, and can be more useful in most situations than three elephants.

Now there are a few situations in which elephants can offer a real advantage in war. One is when you’re fighting forces who have never encountered them before. To the inexperienced foot soldier, an elephant is a huge, loud, monster with giant tusks and a disturbingly prehensile nose. Few inexperienced armies have the discipline to withstand their first sight of an elephant, and many have been known to run in panic in the face of an elephant charge. After a little experience, though, this advantage wears off. Those who have seen elephants a few times learn how to deal with them, by facing them with a dense hedge of pikes or aiming for their eyes, mouths, and the soles of their feet with javelins. The Carthaginian general Hannibal got one battle’s worth of use out of his elephants before the Romans figured out how to counteract them.

The other situation in which elephants can be useful is among warring peoples who all use and fight with elephants. In this case, since all sides know how difficult and expensive it is to maintain elephant forces, putting on a big display of elephants in the field serves as a show of force, demonstrating the resources and organizing capacity of your army, which may convince your opponents to come to terms rather than risk a battle. War elephants were historically used as battlefield showpieces in this way by the kingdoms of India and Southeast Asia, as well as the Hellenistic kingdoms formed from the breakup of Alexander the Great’s empire. Getting effective use of your elephants in such a case, however, requires a major investment of resources which might be more practically spent elsewhere.

In short, if you are bent on conquering the world, I don’t recommend using war elephants. For the occasional times when they would actually be useful, they aren’t worth the cost. (And brutalizing elephants is horrible.)
