Appian of Alexandria Civil Wars 5.12.110

[110] When Octavius disembarked from his ship he slipped and fell, but arose without assistance. While he was yet laying out his camp, Pompeius made his appearance with a large fleet—an astounding spectacle, since Octavius believed that he had been beaten by Agrippa. Pompeius’ cavalry advanced at the same time, rivalling the fleet in rapidity of movement, and his infantry was seen on the other side. The forces of Octavius were terrified at finding themselves surrounded by enemies on three sides, and Octavius himself was alarmed because Messala could not join him. The cavalry of Pompeius assailed Octavius’ men while they were still fortifying their camp. If his infantry and his naval force had attacked simultaneously with the cavalry, Pompeius might have accomplished greater results, but, being inexperienced in war and ignorant of the panic among the troops of Octavius, and hesitating to begin a battle at the approach of nightfall, one part of his forces stationed themselves at the promontory of Coccynus, ¹ while his infantry, deeming it unwise to encamp near the enemy, withdrew to the town of Phœnix. ² Night coming on they went to rest, and Octavius’ soldiers finished their camp, but were incapacitated for battle by toil and want of sleep. They consisted of three legions, and 500 cavalry without horses, 1000 light-armed, and 2000 colonists serving as allies, but not enrolled, besides his fleet.
