Cæsar, still more to animate his soldiers, determined to give them witnesses worthy of their courage, and placed at the head of each legion either one of his lieutenants or his quæstor.[228] He led the attack in person, with his right wing, on the side where the Germans seemed weakest. The signal given, the legions dash forward; the enemy, on his side, rushes to the encounter. On both sides the impetuosity is so great that the Romans, not having time to use the _pilum_, throw it away, and fight hand to hand with the sword. But the Germans, according to their custom, to resist an attack of this kind, form rapidly in phalanxes of three or four hundred men,[229] and cover their bare heads with their bucklers. They are pressed so close together, that even when dead they still remain standing.[230] Such was the ardour of the legionaries, that many rushed upon these sort of tortoises, tearing away the bucklers, and striking the enemies from above.[231] The short and sharp-pointed swords of the Romans had the advantage over the long swords of the Germans.[232] Nevertheless, according to Appian, the legions owed their victory chiefly to the superiority of their tactics and the steadiness with which they kept their ranks.[233] Ariovistus’s left did not resist long; but while it was driven back and put to flight, the right, forming in deep masses, pressed the Romans hard. Young P. Crassus, commander of the cavalry placed at a distance from the thick of the battle, and better placed to judge of its incidents, perceived this, sent the third line to the succour of the wavering legions, and restored the combat. Soon Ariovistus’s right was obliged to give way in its turn; the rout then became general, and the Germans desisted from flight only when they reached the Rhine, fifty miles from the field of battle.[234] They descended, no doubt, the valley of the Ill as far as Rhinau, thus retracing a part of the road by which they had come. (_See Plate 4._) Cæsar sent his cavalry after them; all who were overtaken were cut to pieces; the rest attempted to swim across the river, or sought safety in boats. Among the latter was Ariovistus, who threw himself into a boat[235] he found attached to the bank. According to Plutarch and Appian,[236] 80,000 men perished in the combat and during the pursuit. Two of the wives of the German king experienced the same fate; one was a Sueve, the other a Norician. Of his two daughters, one was killed and the other taken prisoner. Cæsar says that, as he himself pursued the enemy with his cavalry, he experienced a pleasure equal to that given by victory when he recovered, first Procillus, loaded with a triple chain, and who had thrice seen the barbarians draw lots whether he should be burnt alive or not, and, subsequently, M. Mettius, both of whom, as we have seen, had been sent by him as messengers to Ariovistus.
