when he learned on the way that the road beyond the Gap was not practicable, and received information during the day from headquarters indicating the presence of the enemy in the Cove, he decided to change his route. He asked and received the advice of General Thomas regarding it, and adopted one that required crossing Lookout Mountain into Lookout Valley, a march down it to the road to Stevens's Gap, and then up the Mountain again and through the Gap to the other side. While an air-line from Alpine to Thomas's position would not exceed twenty-five miles, by his roundabout route McCook marched nearly sixty miles.

It cannot be denied, however, that the loss of three days by him delayed the execution of the concentrating movement correspondingly, and might have proved fatal.

Bragg affirmed that, having become satisfied of the failure
