Appian of Alexandria Civil Wars 2.10.63

[63] Pompey sent letters to all the kings and cities magnifying his victory, and he expected that Caesar’s army would come over to him directly, conceiving that it was oppressed by hunger and cast down by defeat, and especially the officers because apprehensive of punishment for their bad conduct in the battle. But the latter, as though some god had brought them to repentance, were ashamed of their fault, and as Caesar chided them gently and granted them pardon, they became still more angry with themselves and by a surprising change demanded that they should be decimated according to the law of their country. When Caesar did not agree to this they were still more mortified, and acknowledged that he had been shamefully treated by them. They cried out that he should at least put the standard bearers to death because they themselves would never have run away unless the standards had turned in flight first. Caesar would not consent to this, but he reluctantly punished a few. So great was the zeal excited among all by his moderation that they demanded to be led against the enemy immediately. They urged him vehemently, beseeching and promising to wipe out their disgrace by a splendid victory. Of their own accord they visited each other in military order and took an oath by companies, under the eye of Caesar himself, that they would not leave the field of battle except as victors. ¹
