KENNESAW MOUNTAIN, GA JUNE 27TH, 1864
Kennesaw Mountain, Ga., June 27, 1864. Armies of the Cumberland, Tennessee and Ohio. When Gen. Sherman transferred his line of operations from Pumpkin Vine creek to Allatoona and Acworth on June 4th, he rebuilt the railroad bridge over the Etowah river, established a base of supplies at Allatoona, and on the 9th occupied Big Shanty, the next railroad station south of Acworth. By that time Gen. Johnston, commanding the Confederate forces, had formed a new line along Brush, Pine and Lost Mountains, across the railroad in front of Marietta near Kennesaw mountain. Sherman began the investment of this position on the 1Oth with McPherson's Army of the Tennessee on the left, moving toward Brush mountain and Marietta Thomas, with the Army of the Cumberland occupied the center, moving against Pine and Kennesaw mountains; and Schofield, with the Army of the Ohio was on the right, operating against Lost mountain. Stoneman's cavalry covered the right flank and Garrard's the left, while McCook's cavalry division guarded the communications in the rear and the base at Allatoona. After two weeks of almost constant skirmishing, in which Johnston was forced to abandon Pine and Lost mountains and contract his lines about Kennesaw, Sherman determined to assault the Confederate position. In his report he says: "Upon studying the ground I had no alternative in my turn but to assault his lines or turn his position. Either course had its difficulties and dangers, and I perceived that the enemy and our own officers had settled down to a conviction that I would not assault fortified lines. All looked to me to outflank. An army to be efficient must not settle down to a single mode of offense, but must be prepared to execute any plan which promises success. I wanted, therefore, for the moral effect to make a successful assault against the enemy behind his breastworks, and resolved to attempt it at the point where success would give the largest fruits of victory. The general point selected was the left center, because if I could thrust a strong head of column through that point by pushing it boldly and rapidly two and one-half miles, it would reach the railroad below Marietta, cut off the enemy's right and center from its line of retreat, and then by turning on either part it could be overwhelmed and destroyed. Therefore, on the 24th of June, I ordered that an assault should be made at two points south of Kennesaw on the 27th, giving three days, notice for preparation and reconnaissance, one to be made near Little Kennesaw by General McPherson's troops, and the other about a mile farther south by General Thomas' troops."
The plan of assault was for Schofield on the right to threaten the enemy's extreme flank and at the same time make an attack at some point near the Powder Springs road. McPherson was to make a demonstration on his extreme left, then attack on the south and west of Kennesaw, while strong skirmish lines were to be ready to push forward and seize the crest if opportunity offered. In the center Thomas was to choose some point for his assault and mask his purpose by suitable demonstrations. The real points of attack, where Sherman hoped to break through the lines, were in front of Thomas and McPherson, Schofield movements being more for the purpose of inducing Johnston to weaken his right and center by sending troops to his left, as the action of Reilly's and Byrd's brigades along Olley's creek (q. v.) the day before had caused Johnston much concern, and it was believed that a vigorous demonstration on that part of his line would cause him to reinforce it at the expense of other portions. Accordingly at daybreak on the 27th Schofield sent Cameron's brigade of Cox's division across the bridge built by Byrd the preceding day, while Reilly deployed a portion of his brigade as skirmishers along the Sandtown road, planted a battery on the Confederate flank and under its fire forded the stream. Just as he pushed up the bank on one flank of the Confederate intrenchments Cameron came up on the other and after a brief skirmish the enemy broke and fled.
While these movements were in progress on the right Thomas and McPherson were perfecting their arrangements for the general assault. McPherson's batteries opened a rapid fire on the works at the south end of the ridge known as Little Kennesaw, and Thomas' artillery along the Burnt Hickory and Marietta road began sending in a storm of shot and shell against the intrenchments on Kennesaw. About 9 a.m. M. L. Smith's division of Logan's corps moved forward from McPherson's lines to the attack. Almost at the same instant Newton's division of Howard's corps and Davis' division of Palmer's also advanced on the Confederate works. Smith was met by a galling fire from three batteries and a line of infantry, but his men moved steadily forward and carried two lines of rifle-pits in the face of all opposition. The main line of works was found to be located along the crest of a rocky declivity that it was impossible to scale and the division fell back to the first line of rifle-pits taken, which position was strengthened and held.
Newton's division was formed in two columns, Harker's brigade on the right, Wagner's and Kimball's on the left, and preceded by a strong line of skirmishers advanced, driving in the enemy's pickets, through a tangled mass of undergrowth and fallen trees up to the very foot of the Confederate works, but were unable to carry them. Harker rallied his men and made a second assault, but fell mortally wounded. Wagner's brigade met with no better success and Kimball was then ordered to assault. His command moved forward gallantly to the foot of the works, but was met with such a stubborn resistance that it was compelled to fall back with heavy loss. Newton's pickets continued to hold the captured rifle-pits, where they were afterward relieved by Stanley s division.
Davis massed his troops in an open field in the rear of the Federal breastworks and about 600 yards from the line of works to be assaulted. The intervening ground was exceedingly rough, a good portion of it being covered with a dense undergrowth. Morgan's brigade was held in the Union trenches as a reserve and at the given signal the brigades of McCook and Mitchell sprang forward over their own works and dashed across the rough ground in the face of the enemy's fire. They reached the enemy's works, but, owing to the intense heat and the strenuous exertions in crossing the broken ground, were too much exhausted to mount the parapet to which their impetuous valor had carried them. McCook fell, dangerously wounded, and Col. Harmon of the 125th Ill assumed command of the brigade, but fell almost immediately. Col. Dilworth, of the 85th Ill., then took command and heroically led the brigade against the enemy, many of the men falling in the trenches on the threshold of victory. Mitchell's brigade moved in column parallel with McCook's and in its front a similar drama was being enacted. A problem now presented itself. To withdraw the troops was to receive the full effect of the enemy's unrestrained fire; to attempt a renewal of the assault was equally hazardous. Under the circumstances Davis recommended to Thomas that the position be held and the troops intrenched where they were. Thomas ordered this to be done and tools were immediately sent forward to the men. That night stronger works were thrown up and the division occupied a line of trenches only a few yards from those of the enemy. The Union losses in the attacks on Kennesaw mountain numbered about 2,500 in killed and wounded. Johnston admitted a loss of "over 500." The assault had failed of its purpose, but at every point of attack the Federal lines had been advanced and made permanent, proving a constant menace to the Confederate position. On the night of the 29th an attempt was made to drive Davis from his position, which was the closest to the enemy's lines, but it was repulsed. Under the circumstances Johnston had his engineer prepare a new line along the north side of the Chattahoochee river, crossing the railroad near Smyrna. On the night of the 28th he began the removal of his trains and on the night of July 2 the entire Confederate army evacuated Kennesaw mountain.
