Sure enough, as indicated by the change of commanders, the enemy was about to assume the offensive. On the 20th he came out and attacked the Army of the Cumberland most furiously. Hooker's corps, and Newton's and Johnson's divisions were the principal ones engaged in this contest, which lasted more than an hour; but the Confederates were then forced to fall back inside their main lines. The losses were quite heavy on both sides. On this day General Gresham, since our Postmaster-General, was very badly wounded. During the night Hood abandoned his outer lines, and our troops were advanced. The investment had not been relinquished for a moment during the day.
During the night of the 21st Hood moved out again, passing by our left flank, which was then in motion to get a position farther in rear of him, and a desperate battle ensued, which lasted most of the day of the 22d. At first the battle went very much in favor of the Confederates, our troops being somewhat surprised. While our troops were advancing they were struck in flank, and their flank was enveloped. But they had become too thorough veterans to be thrown into irreparable confusion by an unexpected attack when off their guard, and soon they were in order and engaging the enemy, with the advantage now of knowing where their antagonist was. The field of battle continued to expand until it embraced about seven miles of ground. Finally, however, and before night, the enemy was driven back into the city (*26).
It was during this battle that McPherson, while passing from one column to another, was instantly killed. In his death the army lost one of its ablest, purest and best generals.
Garrard had been sent out with his cavalry to get upon the railroad east of Atlanta and to cut it in the direction of Augusta. He was successful in this, and returned about the time of the battle. Rousseau had also come up from Tennessee with a small division of cavalry, having crossed the Tennessee River about Decatur and made a raid into Alabama. Finally, when hard pressed, he had come in, striking the railroad in rear of Sherman, and reported to him about this time.
The battle of the 22d is usually known as the Battle of Atlanta, although the city did not fall into our hands until the 2d of September. Preparations went on, as before, to flank the enemy out of his position. The work was tedious, and the lines that had to be maintained were very long. Our troops were gradually worked around to the east until they struck the road between Decatur and Atlanta. These lines were strongly fortified, as were those to the north and west of the city--all as close up to the enemy's lines as practicable--in order to hold them with the smallest possible number of men, the design being to detach an army to move by our right and try to get upon the railroad down south of Atlanta.
On the 27th the movement by the right flank commenced. On the 28th the enemy struck our right flank, General Logan commanding, with great vigor. Logan intrenched himself hastily, and by that means was enabled to resist all assaults and inflict a great deal of damage upon the enemy. These assaults were continued to the middle of the afternoon, and resumed once or twice still later in the day. The enemy's losses in these unsuccessful assaults were fearful.
During that evening the enemy in Logan's front withdrew into the town. This now left Sherman's army close up to the Confederate lines, extending from a point directly east of the city around by the north and west of it for a distance of fully ten miles; the whole of this line being intrenched, and made stronger every day they remained there.
In the latter part of July Sherman sent Stoneman to destroy the railroads to the south, about Macon. He was then to go east and, if possible, release our prisoners about Andersonville.
