Phocion

However, when their sea-coast was being devastated by Micion, who landed at Rhamnus with a horde of Macedonians and mercenaries and overran the adjacent territory, Phocion led the Athenians out against him. And as they marched, men would run up to their general from all sides and show him what to do. He was advised to seize a hill here, to send his horsemen around thither, or to make his attack upon the enemy there. O Heracles, said Phocion, how many generals I see, and how few soldiers!

Again, after he had drawn up his men-at-arms, one of them went out far in advance of the rest, and then was stricken with fear when an enemy advanced to meet him, and went back again to his post. Shame on thee, young man, said Phocion, for having abandoned two posts, the one which was given thee by thy general, and the one which thou didst give thyself. However, he attacked the enemy, routed them utterly, and slew Micion himself together with many others.
