boats, and under cover of night float by the pickets of the enemy at the north base of Lookout, down to Brown’s Ferry, then land on the south side and capture or drive away the pickets at that point.  Smith was to march with the remainder of the detail, also under cover of night, by the north bank of the river to Brown’s Ferry, taking with him all the material for laying the bridge as soon as the crossing was secured.

On the 26th, Hooker crossed the river at Bridgeport and commenced his eastward march.  At three o’clock on the morning of the 27th, Hazen moved into the stream with his sixty pontoons and eighteen hundred brave and well-equipped men.  Smith started enough in advance to be near the river when Hazen should arrive.  There are a number of detached spurs of hills north of the river at Chattanooga, back of which is a good road parallel to the stream, sheltered from the view from the top of Lookout.  It was over this road Smith marched.  At five o’clock Hazen landed at Brown’s Ferry, surprised the picket guard, and captured most of it.  By seven o’clock the whole of Smith’s force was ferried over and in possession of a height commanding the ferry.  This was speedily fortified, while a detail was laying the pontoon bridge.  By ten o’clock the bridge was laid, and our extreme right, now in Lookout valley, was fortified and connected with the rest of the army.  The two bridges over the Tennessee River—­a flying one at Chattanooga and the new one at Brown’s Ferry—­with the road north of the river, covered from both the fire and the view of the enemy, made the connection complete.  Hooker found but slight obstacles in his way, and on the afternoon of the 28th emerged into Lookout valley at Wauhatchie.  Howard marched on to Brown’s Ferry, while Geary, who commanded a division in the 12th corps, stopped three miles south.  The pickets of the enemy on the river below were now cut off, and soon came in and surrendered.

The river was now opened to us from Lookout valley to Bridgeport.  Between Brown’s Ferry and Kelly’s Ferry the Tennessee runs through a narrow gorge in the mountains, which contracts the stream so much as to increase the current beyond the capacity of an ordinary steamer to stem it.  To get up these rapids, steamers must be cordelled; that is, pulled up by ropes from the shore.  But there is no difficulty in navigating the stream from Bridgeport to Kelly’s Ferry.  The latter point is only eight miles from Chattanooga and connected with it by a good wagon-road, which runs through a low pass in the Raccoon Mountains on the south side of the river to Brown’s Ferry, thence on the north side to the river opposite Chattanooga.  There were several steamers at Bridgeport, and abundance of forage, clothing and provisions.
