Kentucky for two months, during which it served as an army of occupation. In June it was ordered to the support of Ulysses S. Grant, who was then besieging Vicksburg, and proceeding there promptly, it participated in the investment of the city, although not under fire. Upon the surrender of Vicksburg, Parke's two divisions joined the main army in its movement on Jackson, Mississippi, and became engaged in the fighting there, with a loss of 34 killed, 229 wounded, and 28 missing; total, 291. The 1st Division was then under command of Brig. Gen. Thomas Welsh, General Willcox having been assigned to duty in Indiana. The Vicksburg Campaign had been a costly one for the Corps, not due to battle casualties, but to disease. Among those who succumbed to the deadly malaria of the Vicksburg camps was General Welsh, who, soon after, went home to die. The corps left Mississippi in August, 1863, and returned to Kentucky, where, after a short rest, it joined in Burnside's advance into East Tennessee, a movement that had already commenced. The two divisions were now reduced to about 6,000 men. General Parke having been made chief of staff of the Army of the Ohio, General Potter succeeded to the command of the corps, with Brig. Gen.

This was followed by the occupation of Knoxville and the gallant defense against James Longstreet's besieging forces, terminating December 4, in the defeat and withdrawal of the enemy. Overland Campaign General Willcox resumed command of the corps on January 17, 1864, relieving General Potter; on January 26, Parke relieved Willcox, who then took command of the 2nd Division. General Burnside was again assigned to duty as commander of his old corps, which was ordered to Annapolis, Maryland, for reorganization. In April, the corps was composed of the four divisions of Thomas G. Stevenson, Potter, Willcox, and Ferrero, the latter division being composed wholly of African-American troops. The corps numbered 19,331 present for duty, with 42 pieces of field artillery; but this number was soon increased, the morning reports of May 10 showing a strength of 32,708. In addition to the four divisions, with their two batteries each, there was a
