Bragg's movement must involve Buckner's and ensure the junction of the two corps. Buckner had been on the left bank of the Hiawassee River two days only when, on the 7th of September, he received orders to start out at once on the road to the south. Bragg gave him at the same time a rendezvous in McLemore's Cove. Marching over forty-four miles in eight-and-forty hours, Buckner arrived on the 9th on the banks of the Chickamauga, and posted himself a few miles above Polk's corps on Anderson's farm, between Gordon's Mills and Crawfish Spring; Forrest had ordered Pegram's division to defend as long as possible the banks of the Tennessee from Harrison to Chattanooga and to cover the retreat of the army. He himself had proceeded with Armstrong's division into the valley of the Chattooga, where Wheeler was just arriving from another direction. To the three divisions of cavalry thus collected was assigned the task of delaying McCook's march.

Rosecrans, shut up within a narrow valley, did not yet suspect the movements executed by his adversaries behind the high wall which separated him from them. Having found Bragg in force on the 7th before Summertown, he concluded therefrom that Bragg intended to hold his ground in Chattanooga. As he could not approach him directly, he resolved to threaten his communications by driving the heads of the columns in his centre and on his right beyond the mountains upon the roads which intersect the Dalton and Atlanta Railway. In the morning Negley was occupying Frick's Gap and Stevens' Gap; on the 9th, some time in the day, he was going beyond the slopes of Missionary Ridge and posting himself in McLemore's Cove, at Rodgers' farm, near to the banks of the Chickamauga. Baird was coming to take his place in the defiles, so as to be in a position to support Negley, but the two other divisions of the Fourteenth corps did not leave Trenton, where they had been for the last three days. A like movement was simultaneously accomplished by General McCook. On the 8th he was massing his corps in the vicinity of Valley Head, and the two brigades of Carlin and Heg of Davis' division were occupying the eastern side of Winston's Gap. Stanley, having resumed the command of the cavalry which had crossed at Caperton's Ferry on the 29th of August, was crossing Lookout Mountain and penetrating
