Cæsar, seeing that Ariovistus persisted in shutting himself up in his camp and intercepting his communications, sought to re-establish them, chose an advantageous position about 600 paces (900 mètres) beyond that occupied by the Germans, and led thither his army drawn up in three lines. He kept the first and second under arms, and employed the third on the retrenchments. The spot on which he established himself is perhaps the eminence situated on the Little Doller, to the north of Schweighausen. Ariovistus sent thither about 16,000 of his light troops and all his cavalry, to intimidate the Romans and impede the works. Nevertheless, the third line continued them, and the two others repelled the attack. The camp once fortified, Cæsar left in it two legions and a part of the auxiliaries, and took back the four others to the principal camp. The two Roman camps were 3,600 mètres distant from each other.
Hitherto Cæsar had been satisfied with drawing out his troops and backing them upon his retrenchments; the next day, persisting in his tactics (instituto suo) of trying to provoke Ariovistus to fight, he drew them up at a certain distance in advance of the principal camp, and placed them in order of battle (paulum a majoribus castris progressus, aciem instruxit). In spite of this advanced position (ne tum quidem), Ariovistus persisted in not coming out. The Roman army re-entered the camp towards midday, and a part of the German troops immediately attacked the small camp. Both armies fought resolutely till evening, and there were many wounded on both sides. Astonished at seeing that, in spite of this engagement, Ariovistus still avoided a general battle, Cæsar interrogated the prisoners, and learnt that the matrons charged with consulting destiny had declared that the Germans could not be conquerors if they fought before the new moon.225
Battle against the Germans.
VIII. Next day, leaving a sufficient guard in the two camps, Cæsar placed all his auxiliaries in view of the enemy, in advance of the smaller camp; the number of the legionaries being less than that of the Germans, he sought to conceal his inferiority from the enemy by displaying other troops. While the Germans took these auxiliaries for the two legions which occupied the lesser camp, the latter left it by the Decuman gate, and, unperceived, went to rejoin the other four. Then Cæsar drew up his six legions in three lines, and, marching forward, he led them up to the enemy’s camp (usque ad castra hostium accessit). This offensive movement allowed the Germans no longer the choice of avoiding battle: they quitted their camp, descended into the plain,226 drew up in line, by order of nations, at equal intervals – Harudes, Marcomanni, Suevi, Triboces, Vangiones, Nemetes, and Sedusii; and, to deprive themselves of all possibility of flight, inclosed themselves on the sides and in the rear by a circuit of carriages and wagons, on which they placed their women: dishevelled and in tears, these implored the warriors, as they marched to the battle, not to deliver them in slavery to the Romans. In this position, the Roman army faced the east, and the German army the west, and their lines extended over a space now partly covered by the forest of Nonnenbruch.227
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 boat235 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.
The report of this glorious exploit having spread beyond the Rhine, the Suevi, who had come to its banks, returned home. The Ubii, who dwelt near the river, pursued their terrified bands, and slew a considerable number of the fugitives.
Cæsar, having concluded two great wars in one single campaign, placed his army in winter quarters among the Sequani rather sooner than the season required – at the beginning of September – and left them under the command of Labienus. He then left, and went to hold the assemblies in Cisalpine Gaul.237
Observations.
IX. There are several things worthy of remark in this campaign: —
1. The resolution taken by Cæsar to gain possession of Besançon, and thus to anticipate Ariovistus. We see the importance which he attaches to that military position as a point of support and of supply.
2. The facility with which a whole legion transforms itself into cavalry.
3. The judicious use which Cæsar makes of his light troops (alarii), by assembling them in mass, so that the enemy should believe in a greater number of legions.
4. Lastly, this singular circumstance, that the third line, which serves as reserve and decides the fate of the battle, receives from young P. Crassus, and not from the general-in-chief, the order to attack.
The dates of the principal events of this year may be indicated in the following manner: —

WAR AGAINST THE BELGÆ
League of the Belgæ. Cæsar advances from Besançon to the Aisne.
I. THE brilliant successes gained by Cæsar over the Helvetii and the Germans had delivered the Republic from an immense danger, but at the same time they had roused the distrust and jealousy of most of the nations of Gaul. These conceived fears for their independence, which were further increased by the presence of the Roman army
