[95] September,¹ and was also added to the Fifteenth Corps, becoming the Fourth Division. The four divisions having been concentrated at Memphis, moved thence to Chattanooga, where they participated in the battles of Lookout Mountain and Missionary Ridge, November 23-25, 1863. General Frank P. Blair was in command of the corps, General Sherman having been promoted, October 27, 1863, to the command of the three corps composing the Army of the Tennessee. The four divisions of the Fifteenth Corps were commanded at Missionary Ridge by Generals Osterhaus, Morgan L. Smith, John E. Smith,²and Hugh Ewing. The losses of the corps in that battle, and in the minor actions connected with it. aggregated 295 killed, 1,402 wounded, and 292 missing; total 1,989. After this battle the corps marched to the relief of Knoxville, arriving there December 6, 1863, two days after Longstreet's retreat. The corps then returned to Chattanooga, moving thence into Northern Alabama, where it went into winter quarters.

Under command of General Logan, it was actively engaged on the Atlanta campaign of 1864; its division commanders were Generals Osterhaus, Morgan L. Smith, John E. Smith, and Harrow. The Third Division (John E Smith's) garrisoned points on Sherman's line of communication, and so was not present with the advancing columns. After the fall of Atlanta, Harrow's (4th) Division was consolidated with the others, and its place was taken by Corse's Division of the Sixteenth Corps. General Corse, with a provisional command from the Fifteenth Corps, made the famous defense of Allatoona Pass, an affair remarkable for the courageous, desperate fighting of commander, officers and men.

On the 12th of November, 1864, the corps started with Sherman's Army on the march through Georgia to the sea. General Logan being absent, the corps was under the command of General Osterhaus; the four divisions were commanded by Generals C. R. Woods, Hazen, John E. Smith, and Corse. They contained 60 regiments of infantry, and 4 batteries, the infantry numbering 15,894, present for duty; it was the largest corps in the Army that marched to the sea.

The Army of the Tennessee, under General Howard, formed the right wing of Sherman's Army as it marched through Georgia on its way to the sea, and was composed of the Fifteenth and Seventeenth Corps, only, that part of the Sixteenth Corps--2 divisions — which had served with the Army of the Tennessee on the Atlanta campaign having been consolidated with the two other corps. Although the three other corps in Sherman's Army marched uninterrupted to the sea, the Fifteenth had a brisk engagement at Griswoldville, in which Walcutt's Brigade, of Woods' Division, repelled a determined attack; and, again, upon reaching the sea, Hazen's Division was the one selected for the storming of Fort McAllister.

Savannah was evacuated December 21, 1864, after a short siege, and on the 1st of February, Sherman's Army started on its grand, victorious march through the Carolinas. General Logan having returned, he was again in command of his corps, which now numbered 15,755, infantry and artillery. It encountered some fighting in forcing disputed crossings at some of the larger rivers, and captured Columbia, S. C., General C. R. Woods' Division occupying the city at the time it was burned. The corps was also in line at the battle of Bentonville, N. C., March 19, 1865; but General Slocum had won a substantial victory with his wing of the Army, and but little fighting, comparatively, devolved upon the Army of the Tennessee.

Johnston's Army having surrendered April 26th, time corps continued its northward march, and, arriving at Washington May 20th, participated in the Grand Review of May 24, 1865. It proceeded, June 2d, to Louisville, Ky., and in the latter part of that month the Second Division was ordered to Little Rock, Ark., where it served with the Army of Occupation. The organization was discontinued August 1, 1865.
