It is especially good also to have an understanding of warfare. For I have also often wondered why outcomes in armed conflicts vary, and that whereas the Greeks have as a result been defeated by the Romans and the Persians by the Greeks, even so the Persians have never been defeated by the Romans; instead the nations of inner Asia are boasting of freedom and persist in asserting equality with us. So in allowing myself to consider this question, I found that the cause is neither superior generalship nor overall military power (for in war, no account is taken of numbers by the valiant), but rather the armament and the form of the military equipment.
Thus Africanus began the section of the Kestoi concerning military matters. By the time he wrote the Kestoi between 227 and 231 Rome had been fighting the Parthians in the east on and off for 280 years with little success. During Africanus’ own lifetime Septimius Severus sacked the the Parthian capital of Ctesiphon but just as quickly withdrew. His successors Caracalla and Macrinus had diminishing success in their attempts to keep the Parthians at bay. The situation became even worse in 224 when Ardashir I overthrew the Parthians, established the new Sassanid dynasty, and announced his intention to restore the borders of the ancient Achaemenid Empire.
War was clearly imminent, and when Africanus dedicated the Kestoi to the young emperor Alexander Severus it seems he intended the sections on military matters to serve as advice for the emperor or any other Roman military officer for the coming war.
His views were simply stated: War is decided by training, technology, and tactics. Superiority in all three will ensure victory. While this may seem obvious in the age of high-tech war, this was not always the case, and in the ancient world it was much more common to see fighting spirit and morale as the keys to victory rather than weapons technology. But Africanus seems to have been there, and done that, either on Sepitimius Severus’ campaign in 198, or Caracalla’s invasion in 216, or both. The gritty, down to earth viewpoint of the foot soldier seems to have been quite familiar to him, and we can surmise that he was possibly a junior officer.
In his chapter titled “armaments,” he noted that the Greeks fought with heavy armor and long spears. Their soldiers wore strong helmets with a leather liner on the inside that provided extra padding, greaves, breastplates and carried large round shields which attached to the forearm with two straps. With so much armor, they could only run short distances, but that was enough to run under the arrows of Persian armies and fight at close range.
The Romans, on the other hand, wore tighter-fitting helmets without the leather liner, and tying the cheek protectors made it difficult to turn the head. They wore chain mail instead of heavier scale armor, and their shields were tall and oblong and held by one hand, which made covering the shoulder difficult. But the Romans defeated the Greek phalanxes, because their lighter armor made them more agile and gave them more endurance, while Greek armor left their necks exposed to a quick slice or thrust by the longer Roman swords.
Yet as Africanus noted, “[those who have] been constantly victorious over the Greeks seldom defeated those who had been continually defeated by the Greeks.” In his estimation, Roman soldiers were too quick to lock their shields into a testudo formation and attempt to ride out the Parthian arrow attacks. “Truly such a habit is impractical,” argued Africanus, for while “one stands untouched, distressed by sun and toil, the barbarians in relay [are] attacking and withdrawing again, while by means of attacking successively, the nations are taking rest.” Furthermore,
Roman helmets were too tight-fitting and made it difficult for soldiers to duck to avoid an arrow or slingstone. They were also prone to throw their javelins in one mass shower, “expending ten of them on once chance kill.” Their spears were far too short for holding off a charge from heavily armored Persian cataphracts who carried twenty-foot lances.
To solve this, he recommended that Roman troops be given Greek style helmets and breastplates, and longer spears, and trained to fight with individual initiative as well as in units. They should also be trained to charge the Persians immediately to get underneath the trajectory of their arrows rather than hiding under their shields trying to wait them out.
Persian armies relied on cavalry, and Roman armies fighting the Persians would also need a lot of cavalry. Africanus spent much of his chapter on military affairs discussing the proper care and training of horses. The Parthians trained their horses to remain silent in battle so as not to give away an ambush, and Africanus suggested the Romans should do the same. He also gave recipes for number of noxious potions whose smell startled horses and made them dump their riders.
But by far the greatest threat to Roman cavalry and infantry came from the Sassanid war elephants, and Africanus discussed in detail how to fight them. “An elephant in combat makes the impression of a mountain,” he wrote. “It overturns, it hurls down, it smashes, it annihilates, and it does not disdain at all anyone lying in its way…it overthrows the one who makes a stand, the one who flees it seizes, the one who falls it tramples, the horseman it terrifies, and the charioteers it hits from its tower.” Since horses are terrified of elephants, cavalry should be kept far away from them. Instead, Africanus recommended the use of archers firing burning arrows. Once the wooden tower on the elephant’s back was set on fire, the terrified beast would throw it off.
However, a terrified elephant was even more of an indiscriminate killing machine than a battle-trained one. “I personally am of the opinion, however, that it is better to neither stand up to the elephant at the outset nor to come in close with this manifold danger, but rather to anticipate its threats, its charges, its battles, and its falls,” wrote Africanus. Even better than the flaming arrows were iron caltrops. The army could feign a retreat and bury the sharp iron spikes in the sand behind them. Walking into this early minefield, the elephants would step on the spikes, and in the end “either in its suffering, it destroys those who are trying to relieve its incurable pain, or unable to stand it, collapses in a heap.”
Africanus may have learned about caltrops at the Battle of Nisibis in 217. There, Macrinus’ Roman forces made a tactical retreat and buried the sharp iron spikes in the sand behind them. Parthian cavalry mounted on horses and camels trod on the spikes and threw their riders. The Roman infantry then turned back and finished off the dismounted, lightly armored riders in hand-to-hand combat.
His interest in elephants is all the more intriguing because the Parthians do not seem to have used them. It was the Sassanids who reintroduced war elephants, but when Africanus was writing the Romans had not yet encountered a Sassanid army. In fact, it is not at all clear that the Sassanids used elephants in battle against the Romans until the mid fourth century. But Africanus seems most concerned with practical advice, and it seems strange that he would describe a threat that had not been seen for hundreds of years. But elephants were linked to the Sassanid kings from the very beginning; stories about the rise of Ardashir mentioned a vision his grandfather saw a vision of a man riding on a white elephant, symbolizing power and kingship. It seems more likely that Africanus had some sort of intelligence about Sassanid affinity for elephants and that they were possibly training them for use in war. Anticipating that Roman troops would have to fight them, he consulted the history books to find out how to do it.
Africanus had some other suggestions for training and tactics. Trenches made effective barriers against cavalry charges. Mathematical formulas were given for calculating the heights of walls and the width of rivers. Recipes were given for combustible chemicals that could be applied to enemy siege weapons in the middle of the night and would then burst into flame in daylight. Somewhat more strange were his designs for “intercepting sound” by digging a hole and covering it with a cloth. He claimed that a man standing in the hole could hear distant sounds not normally audible to the human ear. Other seemingly batty ideas probably worked just fine if people thought they would work. If you think that wearing a dead bat around your neck will keep you awake when on late night guard duty, it will. If you think eating a fighting rooster the night before a battle, in Africanus’ words “makes the one eating it heir to its own invincibility, and migrates along with its military prowess to the man,” it will.
But battlefield tactics were only part of the equation. Africanus advocated a war strategy to take advantage of all the weaknesses of the Persian armies. “With them,” he wrote, “the marshaling of an army is makeshift, and means are limited, depending instead on booty from a surprise attack. They bring with them rations measured in days, and a fixed number of missiles also; when they are used up, flight is foreordained.” Persian armies were not professional but were made up of noblemen and ordinary civilians called up for military service. The lack of a rigorous logistics element in Persian armies made them vulnerable to certain strategies, he argued. “What then, is the point in confronting an enemy onslaught, when, if I wait them out, I will see them chased down by the time they have appointed for themselves? Starvation descends upon them the day after time runs out, their meager provisions having been used up to no end.”
To defeat a citizen army Africanus advocated total war. His recommendations are sometimes shocking. In his section titled “On the Destruction of Enemies,” he advocated avoiding battle whenever possible and instead targeting the means for keeping an army in the field:
Time first of all, and attrition, starvation and deadly pestilence must especially be deployed against the barbarians…Let us see if we might even keep them from fleeing in starvation; let annihilation overcome them without the use of the sword, and death without battle. Let us defeat them with the air as an ally and water as our support, with the elements let us arm ourselves against them. I am commander of a secret battle array. The battle I am waging is in the shadows. Let every adversary fall down, when he breathes, thirsts for a drink, or eats. I make everything his peril.
He advocated avoiding battle whenever possible and harassing the enemy with night raids to prevent sleep and weaken an opponent. The enemy’s fields were to be plowed with salt or seeded with poisonous hellebore. Fruit trees in enemy country should be cut down. “For me, more to be commended is one who orders the destruction of everything that grows in abundance,” he argued. The goal was “total annihilation.” Read the rest of this page »
