When he saw all his men in flight, he tore off his riding cloak, and drawing his sword, rushed among the fugitives, hoping either that they would be ashamed and turn back or that he might himself perish with them. Some, indeed, did stop when they saw him in this attitude, and turned back; and brought in this way face to face with the men following them, they cut down not a few of them, supposing them to be Albinus' men, and they routed all their pursuers. At this juncture the cavalry under Laetus came up from one side and completed their victory. Laetus, it appears, so long as the struggle was close, had merely looked on, hoping that both leaders would perish and that the soldiers who survived on either side would give the supreme power to him; but when he saw that Severus' side was prevailing, he also took a hand in the business.
