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 hearing their words.

Having seen enough, we returned to Chattanooga; and in order to hurry up my command, on which so much depended, I started back to Kelly’s in hopes to catch the steamboat that same evening; but on my arrival the boat had gone.  I applied to the commanding officer, got a rough boat manned by four soldiers, and started down the river by night.  I occasionally took a turn at the oars to relieve some tired man, and about midnight we reached Shell Mound, where General Whittaker, of Kentucky, furnished us a new and good crew, with which we reached Bridgeport by daylight.  I started Ewings division in advance, with orders
