Life of Constantine

The van, however, of the enemy, unable to resist the emperor's first assault, threw down their arms, and prostrated themselves at his feet. All these he spared, rejoicing to save human life. But there were others who still continued in arms, and engaged in battle. These the emperor endeavored to conciliate by friendly overtures, but when these were not accepted he ordered his army to commence the attack. On this they immediately turned and betook themselves to flight; and some were overtaken and slain according to the laws of war, while others fell on each other in the confusion of their flight, and perished by the swords of their comrades.
