the latter was already in motion down the Chickamauga. General McCook himself, however, was already at the foot of Stevens Gap on the evening of the 16th, when he reported the whereabouts of his divisions to the general headquarters. He was as ignorant as the other corps commanders of the doings of the enemy.
