general left; and McCook's
division was held somewhat in reserve, about Marietta and the
railroad. On the 10th, having occasion to telegraph to General
Grant, then in Washington, I used this language:

Since July 28th Hood has not attempted to meet us outside his
parapets. In order to possess and destroy effectually his
communications, I may have to leave a corps at the railroad-bridge,
well intrenched, and cut loose with the balance to make a circle of
desolation around Atlanta. I do not propose to assault the works,
which are too strong, nor to proceed by regular approaches. I have
lost a good many regiments, and will lose more, by the expiration
of service; and this is the only reason why I want reenforcements.
We have killed, crippled, and captured more of the enemy than we
have lost by his acts.

On the 12th of August I heard of the success of Admiral Farragut in
entering Mobile Bay, which was regarded as a most valuable
auxiliary to our operations at Atlanta; and learned that I had been
commissioned a major-general in the regular army, which was
unexpected, and not desired until successful in the capture of
Atlanta. These did not change the fact that we were held in check
by the stubborn defense of the place, and a conviction was forced
on my mind that our enemy would hold fast, even though every house
in the town should be battered down by our artillery. It was
evident that we most decoy him out to fight us on something like
equal terms, or else, with the whole army, raise the siege and
attack his communications. Accordingly, on the 13th of August, I
gave general orders for the Twentieth Corps to draw back to the
railroad-bridge at the Chattahoochee, to protect our trains,
hospitals, spare artillery, and the railroad-depot, while the rest
of the army should move bodily to some point on the Macon Railroad
below East Point.

Luckily, I learned just then that the enemy's cavalry, under
General Wheeler, had made a wide circuit around our left flank, and
had actually reached our railroad at Tilton Station, above Resaca,
captured a drove of one thousand of our beef-cattle, and was strong
enough to appear before Dalton, and demand of its commander,
Colonel Raum, the surrender of the place. General John E. Smith,
who was at Kingston, collected together a couple of thousand men,
and proceeded in cars to the relief of Dalton when Wheeler
retreated northward toward Cleveland. On the 16th another
