General Reynolds' division, seizing Shellmound, captured some boats, and from these and material picked up prepared the means of crossing at that point, and General Brannan prepared rafts for crossing his troops at the mouth of Battle Creek.
The laying of the pontoon bridge at Caperton's Ferry was very handsomely done by the troops of General Davis, under the directions of General McCook, who crossed his advance in pontoons at daylight, driving the enemy's cavalry from the opposite side. The bridge was ready for crossing by 11 a.m. the same day, but in plain view from the rebel signal stations opposite Bridgeport.
The bridge at Bridgeport was finished on the 29th of August, but an accident occurred which delayed its final completion till September 2.
THE MOVEMENT ACROSS THE RIVER
was commenced on the 29th and completed on the 4th of September, leaving the regular brigade in charge of the railroad and depot at Stevenson until relieved by Major-General Granger, who was directed, as soon as practicable, to relieve it and take charge of the rear.
General Thomas' corps was to cross as follows: One division at Caperton's and one at Bridgeport, Reynolds at Shellmound in boats, and one division at Battle Creek on rafts. All were to use the bridge at Bridgeport for such portions of their trains as they might find necessary, and to concentrate near Trenton, and send an advance to seize Frick's or Cooper's and Stevens' Gaps on the Lookout Mountain, the only practicable routes leading down the mountains into the valley called McLemore's Cove, which lies at its eastern base and stretches northeastwardly toward Chattanooga.
General McCook's corps was to cross two division at Caperton's Ferry, move to Valley Head, and seize Winston's Gap, while Sheridan was to cross at Bridgeport as soon as the bridge was laid and join the rest of his corps near Winston's, by way of Trenton.
General Crittenden's corps was ordered down the Sequatchie,leaving the two advanced brigades under Hazen and Wagner, with Minty's cavalry, and Wilder's mounted infantry to watch and annoy the enemy. It was to cross the river, following Thomas' corps at all three crossings, and to take post on the Murphy's Hollow road, push an advance brigade to reconnoiter the enemy at the foot of Lookout, and take post at Wauhatchie, communicating from his main body with Thomas on the right up the Trenton Valley and threatening Chattanooga by the pass over the point of Lookout.
The cavalry, crossed at Caperton's and a ford near Island Creek, were to unite in Lookout Valley, take post at Rawlingsville, and reconnoiter boldly toward Rome and Alpine.
These movements were completed by McCook's and Crittenden's corps on the 6th, land by Thomas' corps on the 8th of September. The cavalry for some reason was not pushed with the vigor nor to the extent which orders and the necessities of the campaign required. Its continual movement since that period and the absence of
Major-General Stanley, the chief of cavalry, have prevented a report which may throw some light on the subject.
The first barrier south of the Tennessee being crossed, the enemy was found firmly holding the point of Lookout Mountain with infantry and artillery, while our force on the north side of the river
