considerable loss, although the three combined numbered less than 6,000 muskets; casualties were 60 killed and 315 wounded. By this time the divisions had become so reduced in numbers that a reorganization of the corps became necessary, and so the regiments in White's Division were transferred to the divisions of Potter and Willcox. Under this arrangement Willcox's Division was numbered as the 1st; Potter's, as the 2nd; Ferrero's black troops were designated as the 3rd Division. But in December, Ferrero's Division was permanently detached, and most of his regiments were transferred to the newly organized XXV Corps, which was composed entirely of black troops. General Ferrero himself was assigned to a provisional command at Bermuda Hundred. 1865 The vacancy caused by detaching Ferrero's Division was filled by six new regiments of Pennsylvanians on one-year enlistments, organized into a division of two brigades, the command of which was given to General John F. Hartranft. This division rendered gallant service at Fort Stedman, and Hartranft added to his laurels by the ability displayed at that critical juncture. The morning report for March 31, 1865, showed a corps strength of 18,153, "present for duty, equipped," and 36 pieces of light artillery. With this force the IX Corps entered upon the final campaign, taking a prominent part in the storming of Petersburg, April 2, 1865, which resulted in the evacuation of Richmond and the downfall of the Confederacy. The corps was not only among the foremost in this brilliant assault, but its flags were the first to wave over the public buildings of Petersburg. This was the last battle in which the corps participated, and on July 27, 1865, the IX Corps was officially disbanded.
