on the high ground beyond, strongly intrenched,
with two good pontoon-bridges finished, and was prepared, if
necessary, for an assault by the whole Confederate army. The same
day Garrard's cavalry also crossed over at Roswell, drove away the
cavalry-pickets, and held its ground till relieved by Newton's
division of Howard's corps, which was sent up temporarily, till it
in turn was relieved by Dodge's corps (Sixteenth) of the Army of
the Tennessee, which was the advance of the whole of that army.

That night Johnston evacuated his trenches, crossed over the
Chattahoochee, burned the railroad bridge and his pontoon and
trestle bridges, and left us in full possession of the north or
west bank-besides which, we had already secured possession of the
two good crossings at Roswell and Soap's Creek. I have always
thought Johnston neglected his opportunity there, for he had lain
comparatively idle while we got control of both banks of the river
above him.

On the 13th I ordered McPherson, with the Fifteenth Corps, to move
up to Roswell, to cross over, prepare good bridges, and to make a
strong tete-du-pont on the farther side. Stoneman had been sent
down to Campbellton, with orders to cross over and to threaten the
railroad below Atlanta, if he could do so without too much risk;
and General Blair, with the Seventeenth Corps, was to remain at
Turner's Ferry, demonstrating as much as possible, thus keeping up
the feint below while we were actually crossing above. Thomas was
also ordered to prepare his bridges at Powers's and Paice's
Ferries. By crossing the Chattahoochee above the railroad bridge,
we were better placed to cover our railroad and depots than below,
though a movement across the river below the railroad, to the south
of Atlanta, might have been more decisive. But we were already so
far from home, and would be compelled to accept battle whenever
offered, with the Chattahoochee to our rear, that it became
imperative for me to take all prudential measures the case admitted
of, and I therefore determined to pass the river above the
railroad-bridge-McPherson on the left, Schofield in the centre,
and Thomas on the right. On the 13th I reported to General Halleck
as follows:

All is well. I have now accumulated stores at Allatoona and
Marietta, both fortified and garrisoned points. Have also three
places at which to cross the Chattahoochee in our possession, and
only await General Stoneman's return from a tr
