As Menes gathered the men to discuss his possible next step, he breathed a sigh of relief as he looked around to see that fortunately, none of the top-level commanders had been killed or captured in this horrific loss.

Or else they would suffer just as Perseus's cavalry had suffered.
But for now, relieved at having avoided capture, the commanders had to turn their focus on solving the problem at hand.
