In the battle under the walls of Munda in Spain, against one of Pompey's sons, Caesar had eighty cohorts and eight thousand horsemen, about forty-eight thousand men. Pompey with thirteen legions had sixty thousand troops of the line, six thousand cavalry, six thousand light infantry, six thousand auxiliaries; in all, about eighty thousand men. The struggle, says the narrator, was valiantly kept up, step by step, sword to sword. [19] In that battle of exceptional fury, which hung for a long time in the balance, Caesar had one thousand dead, five hundred wounded; Pompey thirty-three thousand dead, and if Munda had not been so near, scarcely two miles away, his losses would have been doubled. The defensive works of Munda were constructed from dead bodies and abandoned arms. In studying ancient combats, it can be seen that it was almost always an attack from the flank or rear, a surprise action, that won battles, especially against the Romans. It was in this way that their excellent tactics might be confused. Roman tactics were so excellent that a Roman general who was only half as good as his adversary was sure to be victorious. By surprise alone they could be conquered. Note Xanthippe,--Hannibal--the unexpected fighting methods of the Gauls, etc. Indeed Xenophon says somewhere, "Be it agreeable or terrible, the less anything is foreseen, the more does it cause pleasure or dismay. This is nowhere better illustrated than in war where every surprise strikes terror even to those who are much the stronger." But very few fighters armed with cuirass and shield were killed in the front lines. Hannibal in his victories lost almost nobody but Gauls, his cannon-fodder, who fought with poor shields and without armor. Nearly always driven in, they fought, nevertheless, with a tenacity that they never showed under any other command. Thucydides characterizes the combat of the lightly armed, by saying: "As a rule, the lightly armed of both sides took to flight." [20] In combat with closed ranks there was mutual pressure but little loss, the men not being at liberty to strike in their own way and with all their force. Caesar against the Nervii, saw his men, who in the midst of the action had instinctively closed in mass in order to resist the mass of barbarians, giving way under pressure. He therefore ordered his ranks and files to open, so that his legionaries, closed in mass, paralyzed and forced to give way to a very strong pressure, might be able to kill and consequently demoralize the enemy. And indeed, as soon as a man in the front rank of the Nervii fell under the blows of the legionaries, there was a halt, a falling back. Following an attack from the rear, and a melee, the defeat of the Nervii ensued. [21] CHAPTER V MORALE IN ANCIENT BATTLE
