we should have captured half his army and all his artillery and
wagons at the very beginning of the campaign.

Such an opportunity does not occur twice in a single life, but at
the critical moment McPherson seems to have been a little cautious.
Still, he was perfectly justified by his orders, and fell back and
assumed an unassailable defensive position in Sugar Valley, on the
Resaca side of Snake-Creek Gap. As soon as informed of this, I
determined to pass the whole army through Snake-Creek Gap, and to
move on Resaca with the main army.

But during the 10th, the enemy showed no signs of evacuating
Dalton, and I was waiting for the arrival of Garrard's and
Stoneman's cavalry, known to be near at hand, so as to secure the
full advantages of victory, of which I felt certain. 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. At the same time, May 14th, I dispatched
General Garrard, with his cavalry division, down the Oostenaula by
the Rome road, with orders to cross over, if possible, and to
attack or threaten the railroad at any p
