Chapter 24
Caesar, when he observes this, draws off his forces to the next hill, and sent the cavalry to sustain the attack of the enemy. He himself, meanwhile, drew up on the middle of the hill a triple line of his four veteran legions in such a manner, that he placed above him on the very summit the two legions, which he had lately levied in Hither Gaul, and all the auxiliaries; and he ordered that the whole mountain should be covered with men, and that meanwhile the baggage should be brought together into one place, and the position be protected by those who were posted in the upper line. The Helvetii having followed with all their wagons, collected their baggage into one place: they themselves, after having repulsed our cavalry and formed a phalanx, advanced up to our front line in very close order.
Chapter 25
Caesar, having removed out of sight first his own horse, then those of all, that he might make the danger of a11 equal, and do away with the hope of flight, after encouraging his men, joined battle. His soldiers hurling their javelins from the higher ground, easily broke the enemy's phalanx. That being dispersed, they made a charge on them with drawn swords. It was a great hinderance to the Gauls in fighting, that, when several of their bucklers had been by one stroke of the (Roman) javelins pierced through and pinned fast together, as the point of the iron had bent itself, they could neither pluck it out, nor, with their left hand entangled, fight with sufficient ease; so that many, after having long tossed their arm about, chose rather to cast away the buckler from their hand, and to fight with their person unprotected. At length, worn out with wounds, they began to give way, and, as there was in the neighborhood a mountain about a mile off, to betake themselves thither. When the mountain had been gained, and our men were advancing up, the Boii and Tulingi, who with about 15,000 men closed the enemy's line of march and served as a guard to their rear, having assailed our men on the exposed flank as they advanced [prepared] to surround them; upon seeing which, the Helvetii who had betaken themselves to the mountain, began to press on again and renew the battle. The Romans having faced about, advanced to the attack in two divisions; the first and second line, to withstand those who had been defeated and driven off the field; the third to receive those who were just arriving.
