Gallic War

When Caesar was not more than twelve miles distant from the enemy, the embassadors return to him, as had been arranged; who meeting him on the march, earnestly entreated him not to advance any further. When they could not obtain this, they begged him to send on a dispatch to those who had marched in advance of the main army, and forbid them to engage; and grant them permission to send embassadors to the Ubii, and if the princes and senate of the latter would give them security by oath, they assured Caesar that they would accept such conditions as might be proposed by him; and requested that he would give them the space of three days for negociating these affairs. Caesar thought that these things tended to the self-same point [as their other proposal]; [namely] that, in consequence of a delay of three days intervening, their horse, which were at a distance, might return; however, he said, that he would not that day advance further than four miles for the purpose of procuring water; he ordered that they should assemble at that place in as large a number as possible, the following day, that he might inquire into their demands. In the mean time he sends messengers to the officers who had marched in advance with all the cavalry, to order them not to provoke the enemy to an engagement, and if they themselves were assailed, to sustain the attack until he came up with the army.

But the enemy, as soon as they saw our horse, the number of which was 5000, whereas they themselves had not more than 800 horse, because those which had gone over the Meuse for the purpose of foraging had not returned, while our men had no apprehensions, because their embassadors had gone away from Caesar a little before, and that day had been requested by them as a period of truce, made an onset on our men, and soon threw them into disorder. When our men, in their turn, made a stand, they, according to their practice, leaped from their horses to their feet, and stabbing our horses in the belly and overthrowing a great many of our men, put the rest to flight, and drove them forward so much alarmed that they did not desist from their retreat till they had come in sight of our army. In that encounter seventy-four of our horse were slain; among them, Piso, an Aquitanian, a most valiant man, and descended from a very illustrious family; whose grandfather had held the sovereignty of his state, and had been styled friend by our senate. He, while he was endeavoring to render assistance to his brother who was surrounded by the enemy, and whom he rescued from danger, was himself thrown from his horse, which was wounded under him, but still opposed [his antagonists] with the greatest intrepidity, as long as he was able to maintain the conflict. When at length he fell, surrounded on all sides and after receiving many wounds, and his brother, who had then retired from the fight, observed it from a distance, he spurred on his horse, threw himself upon the enemy, and was killed.

After this engagement, Caesar considered that neither ought embassadors to be received to audience, nor conditions be accepted by him from those who, after having sued for peace by way of stratagem and treachery, had made war without provocation. And to wait until the enemy's forces were augmented and their cavalry had returned, he concluded, would be the greatest madness; and knowing the fickleness of the Gauls, he felt how much influence the enemy had already acquired among them by this one skirmish. He [therefore] deemed that no time for concerting measures ought to be afforded them. After having resolved on those things and communicated his plans to his lieutenants and quaestor in order that he might not suffer any opportunity for engaging to escape him, a very seasonable event occurred, namely, that on the morning of the next day, a large body of Germans, consisting of their princes and old men, came to the camp to him to practice the same treachery and dissimulation; but, as they asserted, for the purpose of acquitting themselves for having engaged in a skirmish the day before, contrary to what had been agreed and to what indeed, they themselves had requested; and also if they could by any means obtain a truce by deceiving him. Caesar, rejoicing that they had fallen into his power, ordered them to be detained. He then drew all his forces out of the camp, and commanded the cavalry, because he thought they were intimidated by the late skirmish, to follow in the rear.

Having marshalled his army in three lines, and in a short time performed a march of eight miles, he arrived at the camp of the enemy before the Germans could perceive what was going on; who being suddenly alarmed by all the circumstances, both by the speediness of our arrival and the absence of their own officers, as time was afforded neither for concerting measures nor for seizing their arms, are perplexed as to whether it would be better to lead out their forces against the enemy, or to defend their camp, or seek their safety by flight. Their consternation being made apparent by their noise and tumult, our soldiers, excited by the treachery of the preceding day, rushed into the camp: such of them as could readily get their arms, for a short time withstood our men, and gave battle among their carts and baggage wagons; but the rest of the people, [consisting] of boys and women (for they had left their country and crossed the Rhine with all their families) began to fly in all directions; in pursuit of whom Caesar sent the cavalry.
