Appian of Alexandria Civil Wars 2.13.88

[88] Caesar remained two days at Pharsalus after the victory, offering sacrifice and giving his army a respite from fighting. Then he set free his Thessalian allies and granted pardon to the suppliant Athenians, and said to them, How often will the glory of your ancestors save you from self-destruction? On the third day he marched eastward, having learned that Pompey had fled thither, and for want of triremes he essayed to cross the Hellespont in skiffs. Here Cassius came upon him in mid-stream, with a part of his fleet, as he was hastening to Pharnaces. Although he might have mastered these small boats with his numerous triremes he was panic-stricken by Caesar’s astounding success, which was then heralded with consternation everywhere, and he thought that Caesar had sailed purposely against him. So he extended his hands in entreaty from his trireme toward the skiff, begged pardon, and surrendered his fleet. So great was the power of Caesar’s prestige. I can see no other reason myself, nor can I think of any other instance where fortune was more propitious in a trying emergency than when Cassius, a most valiant man, with seventy triremes, fell in with Caesar when he was unprepared, but did not venture to come to blows with him. And yet he who thus disgracefully surrendered to Caesar, through fear alone, when the latter was crossing the straits, afterward murdered him in Rome when he was at the height of his power; by which fact it is evident that the panic which then seized Cassius was due to the fortune by which Caesar was uplifted. ¹
