During the 24th and 25th of June General Schofield extended his right as far as prudent, so as to compel the enemy to thin out his lines correspondingly, with the intention to make two strong assaults at points where success would give us the greatest advantage. I had consulted Generals Thomas, McPherson, and Schofield, and we all agreed that we could not with prudence stretch out any more, and therefore there was no alternative but to attack "fortified lines," a thing carefully avoided up to that time. I reasoned, if we could make a breach anywhere near the rebel centre, and thrust in a strong head of column, that with the one moiety of our army we could hold in check the corresponding wing of the enemy, and with the other sweep in flank and overwhelm the other half. The 27th of June was fixed as the day for the attempt, and in order to oversee the whole, and to be in close communication with all parts of the army, I had a place cleared on the top of a hill to the rear of Thomas's centre, and had the telegraph-wires laid to it. The points of attack were chosen, and the troops were all prepared with as little demonstration as possible. About 9 A.M. Of the day appointed, the troops moved to the assault, and all along our lines for ten miles a furious fire of artillery and musketry was kept up. At all points the enemy met us with determined courage and in great force. McPherson's attacking column fought up the face of the lesser Kenesaw, but could not reach the summit. About a mile to the right (just below the Dallas road) Thomas's assaulting column reached the parapet, where Brigadier-General Barker was shot down mortally wounded, and Brigadier-General Daniel McCook (my old law-partner) was desperately wounded, from the effects of which he afterward died. By 11.30 the assault was in fact over, and had failed. We had not broken the rebel line at either point, but our assaulting columns held their ground within a few yards of the rebel trenches, and there covered themselves with parapet. McPherson lost about five hundred men and several valuable officers, and Thomas lost nearly two thousand men. This was the hardest fight of the campaign up to that date, and it is well described by Johnston in his "Narrative" (pages 342, 343), where he admits his loss in killed and wounded as

Total …………. 808

This, no doubt, is a true and fair statement; but, as usual, Johnston overestimates our loss, putting it at six thousand, whereas our entire loss was about twenty-five hundred, killed and wounded.

While the battle was in progress at the centre, Schofield crossed Olley's Creek on the right, and gained a position threatening Johnston's line of retreat; and, to increase the effect, I ordered Stoneman's cavalry to proceed rapidly still farther to the right, to Sweetwater. Satisfied of the bloody cost of attacking intrenched lines, I at once thought of moving the whole army to the railroad at a point (Fulton) about ten miles below Marietta, or to the Chattahoochee River itself, a movement similar to the one afterward so successfully practised at Atlanta. All the orders were issued to bring forward supplies enough to fill our wagons, intending to strip the railroad back to Allatoona, and leave that place as our depot, to be covered as well as possible by Garrard's cavalry. General Thomas, as usual, shook his head, deeming it risky to leave the railroad; but something had to be done, and I had resolved on this move, as reported in my dispatch to General Halleck on July 1st:

General Schofield is now south of Olley's Creek, and on the head of Nickajack. I have been hurrying down provisions and forage, and tomorrow night propose to move McPherson from the left to the extreme right, back of General Thomas. This will bring my right within three miles of the Chattahoochee River, and about five miles from the railroad. By this movement I think I can force Johnston to move his whole army down from Kenesaw to defend his railroad and the Chattahoochee, when I will (by the left flank) reach the railroad below Marietta; but in this I must cut loose from the railroad with ten days' supplies in wagons. Johnston may come out of his intrenchments to attack Thomas, which is exactly what I want, for General Thomas is well intrenched on a line parallel with the enemy south of Kenesaw. I think that Allatoona and the line of the Etowah are strong enough for me to venture on this move. The movement is substantially down the Sandtown road straight for Atlanta.

McPherson drew out of his lines during the night of July 2d, leaving Garrard's cavalry, dismounted, occupying his trenches, and moved to the rear of the Army of the Cumberland, stretching down the Nickajack; but Johnston detected the movement, and promptly abandoned Marietta and Kenesaw. I expected as much, for, by the earliest dawn of the 3d of July, I was up at a large spy-glass mounted on a tripod, which Colonel Poe, United States Engineers, had at his bivouac close by our camp. I directed the glass on Kenesaw, and saw some of our pickets crawling up the hill cautiously; soon they stood upon the very top, and I could plainly see their movements as they ran along the crest just abandoned by the enemy. In a minute I roused my staff, and started them off with orders in every direction for a pursuit by every possible road, hoping to catch Johnston in the confusion of retreat, especially at the crossing of the Chattahoochee River.

I must close this chapter here, so as to give the actual losses during June, which are compiled from the official returns by months. These losses, from June 1st to July 3d, were all substantially sustained about Kenesaw and Marietta, and it was really a continuous battle, lasting from the 10th day of June till the 3d of July, when the rebel army fell back from Marietta toward the Chattahoochee River. Our losses were:

Killed and Missing Wounded Total
Loss in June Aggregate 1,790 5,740 7,530

Johnston makes his statement of losses from the report of his
surgeon Foard, for pretty much the same period, viz., from June 4th
to July 4th (page 576):
Killed Wounded Total
Total………… 468 3,480 3,948

In the tabular statement the "missing" embraces the prisoners; and, giving two thousand as a fair proportion of prisoners captured by us for the month of June (twelve thousand nine hundred and eighty-three in all the campaign), makes an aggregate loss in the rebel army of fifty-nine hundred and forty-eight, to ours of seventy-five hundred and thirty—a less proportion than in the relative strength of our two armies, viz., as six to ten, thus maintaining our relative superiority, which the desperate game of war justified.
