These brigades occupied the summit of the mountain.

General Carter L.
Stevenson was in command of the whole.

Why any troops, except artillery with a small infantry guard, were kept on the mountain-top, I do not see.

A hundred men could have held the summit--which is a palisade for more than thirty feet down--against the assault of any number of men from the position Hooker occupied.
The side of Lookout Mountain confronting Hooker's command was rugged, heavily timbered, and full of chasms, making it difficult to advance with troops, even in the absence of an opposing force.

Farther up, the ground becomes more even and level, and was in cultivation.
