July 21st Hood had transferred Hardee's Corps and two Divisions of Wheeler's Cavalry to our rear, going around our left flank, Wheeler attacking Sprague's Brigade of the Sixteenth Army Corps at Decatur, where our trains were parked. At daylight, Stewart's and Cheatham's Corps and the Georgia Militia were withdrawn closer to Atlanta, and placed in a position to attack simultaneously with Hardee, the plan thus involving the destroying of the Army of the Tennessee by attacking it in rear and front and the capturing of all its trains corraled at Decatur. Hardee's was the largest Corps in Hood's Army, and according to Hood there were thus to move upon the Army of the Tennessee about 40,000 troops.
Hood's order of attack was for Hardee to form entirely in the rear of the Army of the Tennessee, but Hardee claims that he met Hood on the night of the 21st; that he was so late in moving his Corps that they changed the plan of attack so that his left was to strike the Seventeenth Corps. He was to swing his right until he enveloped and attacked the rear of the Seventeenth and Fifteenth Corps.
Hood stood in one of the batteries of Atlanta, where he could see Blair's left and the front line of the Fifteenth and Seventeenth Corps. He says he was astonished to see the attack come on Blair's left instead of his rear, and charges his defeat to that fact; but Hardee, when he swung his right and came out in the open, found the Sixteenth Corps in line in the rear of our Army, and he was as much surprised to find us there as our Army was at the sudden attack in our rear. The driving back by the Sixteenth Corps of Hardee's Corps made the latter drift to the left and against Blair, – not only to Blair's left, but into his rear, – so that what Hood declares was the cause of his failure was not Hardee's fault, as his attacks on the Sixteenth Corps were evidently determined and fierce enough to relieve him from all blame in that matter.
Historians and others who have written of the Battle of Atlanta have been misled by being governed in their data by the first dispatches of General Sherman, who was evidently misinformed, as he afterwards corrected his dispatches. He stated in the first dispatch that the attack was at 11 a. m., and on Blair's Corps, and also that General McPherson was killed about 11 a. m. The fact is, Blair was not attacked until half an hour after the attack upon the Sixteenth Corps, and McPherson fell at about 2 p. m. General Sherman was at the Howard House, which was miles away from the scene of Hardee's attack in the rear, and evidently did not at first comprehend the terrific fighting that was in progress, and the serious results that would have been effected had the attack succeeded.
The battle began within fifteen or twenty minutes of 12 o'clock (noon) and lasted until midnight, and covered the ground from the Howard House along the entire front of the Fifteenth (Logan's) Corps, the Seventeenth (Blair's) on the front of the Sixteenth (which was formed in the rear of the Army), and on to Decatur, where Sprague's Brigade of the Sixteenth Army Corps met and defeated Wheeler's Cavalry – a distance of about seven miles.
The Army of the Tennessee had present on that day at Atlanta and Decatur about 26,000 men; there were 10,000 in the Fifteenth Army Corps, 9,000 in the Sixteenth Corps, and 7,000 in the Seventeenth. About 21,000 of these were in line of battle. Three Brigades of the Sixteenth Corps were absent, the Sixteenth Corps having 5,000 men in a single line which received the attack of the four Divisions of Hardee's Corps, Hardee's left, Cleburn's Division lapping the extreme left of Blair and joining Cheatham's Corps which attacked Blair from the Atlanta front; and, according to Hood, they were joined by the Georgia Militia under General Smith. Extending down the line in front of the Armies of the Ohio and the Cumberland, Stewart's Corps occupied the works and held the lines in front of the Army of the Cumberland. The Sixteenth Army Corps fought in the open ground; the Fifteenth and Seventeenth behind intrenchments.
Where I stood just at the rear of the Sixteenth Army Corps, I could see the entire line of that corps, and could look up and see the enemy's entire front as they emerged from the woods, and I quickly saw that both of my flanks were overlapped by the enemy. Knowing General McPherson was some two miles away, I sent a staff officer to General Giles A. Smith, requesting him to refuse his left and protect the gap between the Seventeenth Corps and my right, which he sent word he would do. Later, as the battle progressed, and I saw no movement on the part of General Smith, I sent another officer to inform him that the enemy were passing my right flank, which was nearly opposite his center, and requested him to refuse his left immediately, or he would be cut off. This officer (Lieutenant D. Sheffly, who belonged to the Signal Corps, and acted as my aide only for the time being) found, on reaching Smith, that he was just becoming engaged; that he had received orders to hold his line, with a promise that other troops would be thrown into the gap.
My second messenger, Lieutenant Sheffly, returning over the road upon which McPherson was a few minutes later shot dead, met the General on the road with a very few attendants, and turned to warn him of his dangerous position, assuring him that the enemy held the woods and were advancing. The General paying no heed to the warning and moving on, my aide turned and followed him. They had proceeded but a short distance into the woods when a sharp command, "Halt," was heard from the skirmish-line of the rebels. Without heeding the command, General McPherson and his party wheeled their horses, and at that moment a heavy volley was poured in, killing McPherson and so frightening the horses that they became unmanageable and plunged into the underbrush in different directions. My aide became separated from the General and the rest of the party, and was knocked from his horse by coming in contact with a tree, and lay for some time in an unconscious condition on the ground. As soon as he was sufficiently recovered he returned on foot to me, having lost his horse and equipments. Of General McPherson he saw nothing after his fall. His watch, crushed by contact with the tree, was stopped at two minutes past 2 o'clock, which fixed the time of General McPherson's death.
General McPherson could not have left his point of observation more than a few minutes when I detected the enemy's advance in the woods some distance to my right, and between that flank and General Blair's rear. Fuller quickly changed front with a portion of his brigade to confront them, and pushing promptly to the attack captured their skirmish-line and drove back their main force. Upon the persons of some of these prisoners we found McPherson's papers, field-glass, etc., which conveyed to me the first knowledge I had of his death; or, rather, as I then supposed, of his capture by the enemy; and seeing that the papers were important I sent them by my Chief of Staff with all haste to General Sherman.
General McPherson, it seems, had just witnessed the decisive grapple of the Sixteenth Corps with the charging columns of the enemy, and, as probably conveying his own reflections at that moment, I quote the language of General Strong, the only staff officer present with him at that critical time:
The General and myself, accompanied only by our orderlies, rode on and took positions on the right of Dodge's line, and witnessed the desperate assaults of Hood's army.
The Divisions of Generals Fuller and Sweeney were formed in a single line of battle in the open fields, without cover of any kind (Fuller's Division on the right,) and were warmly engaged. The enemy, massed in columns three or four lines deep, moved out of the dense timber several hundred yards from General Dodge's position, and after gaining fairly the open fields, halted and opened a rapid fire upon the Sixteenth Corps. They, however, seemed surprised to find our infantry in line of battle, prepared for attack, and after facing for a few minutes the destructive fire from the Divisions of Generals Fuller and Sweeney, fell back in disorder to the cover of the woods. Here, however, their lines were quickly reformed, and they again advanced, evidently determined to carry the position.
The scene at this time was grand and impressive. It seemed to us that every mounted officer of the attacking column was riding at the front of, or on the right or left of, the first line of battle. The regimental colors waved and fluttered in advance of the lines, and not a shot was fired by the rebel infantry, although the movement was covered by a heavy and well-directed fire from artillery, which was posted in the woods and on higher ground, and which enabled the guns to bear upon our troops with solid shot and shell, firing over the attacking column.
It seemed impossible, however, for the enemy to face the sweeping, deadly fire from Fuller's and Sweeney's Divisions, and the guns of the Fourteenth Ohio
