CHAPTER XVIII.
ATLANTA CAMPAIGN--BATTLES ABOUT ATLANTA JULY, 1864.
As before explained, on the 3d of July, by moving McPherson's entire army from the extreme left, at the base of Kenesaw to the right, below Olley's Creek, and stretching it down the Nickajack toward Turner's Ferry of the Chattahoochee, we forced Johnston to choose between a direct assault on Thomas's intrenched position, or to permit us to make a lodgment on his railroad below Marietta, or even to cross the Chattahoochee.

Of course, he chose to let go Kenesaw and Marietta, and fall back on an intrenched camp prepared by his orders in advance on the north and west bank of the Chattahoochee, covering the railroad-crossing and his several pontoon-bridges.

I confess I had not learned beforehand of the existence of this strong place, in the nature of a tete-du-pont, and had counted on striking him an effectual blow in the expected confusion of his crossing the Chattahoochee, a broad and deep river then to his rear.

Ordering every part of the army to pursue vigorously on the morning of the 3d of July, I rode into Marietta, just quitted by the rebel rear-guard, and was terribly angry at the cautious pursuit by Garrard's cavalry, and even by the head of our infantry columns.

But Johnston had in advance cleared and multiplied his roads, whereas ours had to cross at right angles from the direction of Powder Springs toward Marrietta, producing delay and confusion.
