Appian of Alexandria Civil Wars 4.14.112

[112] As the camp was in a strong position it was guarded by only a few men, for which reason Antony easily overcame them. Cassius’ soldiers outside the camp were already worsted, and when they saw that the camp was taken they scattered in disorderly flight. The victory was complete and alike on either side, Brutus defeating the enemy’s left wing and taking their camp, while Antony overcame Cassius and ravaged his camp with irresistible courage. There was great slaughter on both sides, but by reason of the extent of the plain and the clouds of dust they were ignorant of each other’s fate. When they learned the facts they recalled their scattered forces. Those who returned resembled porters rather than soldiers, and did not at once perceive each other nor see anything clearly. Otherwise either party would have flung down their burdens and fiercely attacked the others carrying off plunder in this disorderly fashion. According to conjecture the number of killed on the side of Cassius, including slave shield-bearers, was about 8000 and on the side of Octavius double that number. ¹
