the battle of Chickamauga that he feared they could
not be got out of their trenches to assume the offensive; that
Bragg had detached Longstreet with a considerable force up into
East Tennessee, to defeat and capture Burnside; that Burnside was
in danger, etc.; and that he (Grant) was extremely anxious to
attack Bragg in position, to defeat him, or at least to force him
to recall Longstreet. The Army of the Cumberland had so long been
in the trenches that he wanted my troops to hurry up, to take the
offensive first; after which, he had no doubt the Cumberland army
would fight well. Meantime the Eleventh and Twelfth Corps, under
General Hooker, had been advanced from Bridgeport along the
railroad to Wauhatchee, but could not as yet pass Lookout Mountain.
A pontoon-bridge had been thrown across the Tennessee River at
Brown's Ferry, by which supplies were hauled into Chattanooga from
Kelly's and Wauhatchee..

Another bridge was in course of construction at Chattanooga, under
the immediate direction of Quartermaster-General Meigs, but at the
time all wagons, etc., had to be ferried across by a flying-bridge.
Men were busy and hard at work everywhere inside our lines, and
boats for another pontoon-bridge were being rapidly constructed
under Brigadier-General W. F. Smith, familiarly known as "Baldy
Smith," and this bridge was destined to be used by my troops, at a
point of the river about four miles above Chattanooga, just below
the mouth of the Chickamauga River. General Grant explained to me
that he had reconnoitred the rebel line from Lookout Mountain up to
Chickamauga, and he believed that the northern portion of
Missionary Ridge was not fortified at all; and he wanted me, as
soon as my troops got up, to lay the new pontoon-bridge by night,
cross over, and attack Bragg's right flank on that part of the
ridge abutting on Chickamauga Creek, near the tunnel; and he
proposed that we should go at once to look at the ground. In
company with Generals Thomas, W. F. Smith, Brannan, and others, we
crossed by the flying-bridge, rode back of the hills some four
miles, left our horses, and got on a hill overlooking the whole
ground about the mouth of the Chickamauga River, and across to the
Missionary Hills near the tunnel. Smith and I crept down behind a
fringe of trees that lined the river-bank, to the very point
selected for the new bridge, where we sat for some time, seeing the
rebel pickets on the opposite bank, and almost
