He was taught in a rough school; for the early campaigns in which he took part were waged against the gallant generals and splendid soldiery of the British King.

By experience he had grown to add caution to his dauntless energy.

Once, after the battle of Brandywine, when he had pushed close to the enemy, with his usual fearless self-confidence, he was surprised in a night attack by the equally daring British general Grey, and his brigade was severely punished with the bayonet.

It was a lesson he never forgot; it did not in any way abate his self-reliance or his fiery ardor, but it taught him the necessity of forethought, of thorough preparation, and of ceaseless watchfulness.

A few days later he led the assault at Germantown, driving the Hessians before him with the bayonet.
