C. Julius Caesar, Gallic War

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.
