The barbarians, upon perceiving the design of the Romans, sent forward their cavalry and charioteers, a class of warriors of whom it is their practice to make great use in their battles, and following with the rest of their forces, endeavored to prevent our men landing. In this was the greatest difficulty, for the following reasons, namely, because our ships, on account of their great size, could be stationed only in deep water; and our soldiers, in places unknown to them, with their hands embarrassed, oppressed with a large and heavy weight of armor, had at the same time to leap from the ships, stand amid the waves, and encounter the enemy; whereas they, either on dry ground, or advancing a little way into the water, free in all their limbs in places thoroughly known to them, could confidently throw their weapons and spur on their horses, which were accustomed to this kind of service. Dismayed by these circumstances and altogether untrained in this mode of battle, our men did not all exert the same vigor and eagerness which they had been wont to exert in engagements on dry ground.
When Caesar observed this, he ordered the ships of war, the appearance of which was somewhat strange to the barbarians and the motion more ready for service, to be withdrawn a little from the transport vessels, and to be propelled by their oars, and be stationed toward the open flank of the enemy, and the enemy to be beaten off and driven away, with slings, arrows, and engines: which plan was of great service to our men; for the barbarians being startled by the form of our ships and the motions of our oars and the nature of our engines, which was strange to them, stopped, and shortly after retreated a little. And while our men were hesitating [whether they should advance to the shore], chiefly on account of the depth of the sea, he who carried the eagle of the tenth legion, after supplicating the gods that the matter might turn out favorably to the legion, exclaimed, "Leap, fellow soldiers, unless you wish to betray your eagle to the enemy. I, for my part, will perform my duty to the commonwealth and my general." When he had said this with a loud voice, he leaped from the ship and proceeded to bear the eagle toward the enemy. Then our men, exhorting one another that so great a disgrace should not be incurred, all leaped from the ship. When those in the nearest vessels saw them, they speedily followed and approached the enemy.
The battle was maintained vigorously on both sides. Our men, however, as they could neither keep their ranks, nor get firm footing, nor follow their standards, and as one from one ship and another from another assembled around whatever standards they met, were thrown into great confusion. But the enemy, who were acquainted with all the shallows, when from the shore they saw any coming from a ship one by one, spurred on their horses, and attacked them while embarrassed; many surrounded a few, others threw their weapons upon our collected forces on their exposed flank.
