Hooker's Twentieth Corps was at once moved down to within easy supporting distance of McPherson; and on the 11th, perceiving signs of evacuation of Dalton, I gave all the orders for the general movement, leaving the Fourth Corps (Howard) and Stoneman's cavalry in observation in front of Buzzard-Roost Gap, and directing all the rest of the army to march through Snake-Creek Gap, straight on Resaca.

The roads were only such as the country afforded, mere rough wagon-ways, and these converged to the single narrow track through Snake-Creek Gap; but during the 12th and 13th the bulk of Thomas's and Schofield's armies were got through, and deployed against Resaca, McPherson on the right, Thomas in the centre, and Schofield on the left.

Johnston, as I anticipated, had abandoned all his well-prepared defenses at Dalton, and was found inside of Resaca with the bulk of his army, holding his divisions well in hand, acting purely on the defensive, and fighting well at all points of conflict.

A complete line of intrenchments was found covering the place, and this was strongly manned at all points.

On the 14th we closed in, enveloping the town on its north and west, and during the 15th we had a day of continual battle and skirmish.
At the same time I caused two pontoon-bridges to be laid across the Oostenaula River at Lay's Ferry, about three miles below the town, by which we could threaten Calhoun, a station on the railroad seven miles below Resaca.
