the enemy was
dispersed from our front, or even after the battle for this purpose was
begun. Hooker's orders, therefore, were designed to get his force past
Lookout Mountain and Chattanooga Valley, and up to Missionary Ridge. By
crossing the north face of Lookout the troops would come into
Chattanooga Valley in rear of the line held by the enemy across the
valley, and would necessarily force its evacuation. Orders were
accordingly given to march by this route. But days before the battle
began the advantages as well as the disadvantages of this plan of action
were all considered. The passage over the mountain was a difficult one
to make in the face of an enemy. It might consume so much time as to
lose us the use of the troops engaged in it at other points where they
were more wanted. After reaching Chattanooga Valley, the creek of the
same name, quite a formidable stream to get an army over, had to be
crossed. I was perfectly willing that the enemy should keep Lookout
Mountain until we got through with the troops on Missionary Ridge. By
marching Hooker to the north side of the river, thence up the stream,
and recrossing at the town, he could be got in position at any named
time; when in this new position, he would have Chattanooga Creek behind
him, and the attack on Missionary Ridge would unquestionably cause the
evacuation by the enemy of his line across the valley and on Lookout
Mountain. Hooker's order was changed accordingly. As explained
elsewhere, the original order had to be reverted to, because of a flood
in the river rendering the bridge at Brown's Ferry unsafe for the
passage of troops at the exact juncture when it was wanted to bring all
the troops together against Missionary Ridge.

The next day after Sherman's arrival I took him, with Generals Thomas
and Smith and other officers, to the north side of the river, and showed
them the ground over which Sherman had to march, and pointed out
generally what he was expected to do. I, as well as the authorities in
Washington, was still in a great state of anxiety for Burnside's safety.
Burnside himself, I believe, was the only one who did not share in this
anxiety. Nothing could be done for him, however, until Sherman's troops
were up. As soon, therefore, as the inspection was over, Sherman
started for Bridgeport to hasten matters, rowing a boat himself, I
believe, from Kelly's Ferry. Sherman had left Bridgeport the night
of the 14th, reached Chattanoog
