Grant, with the armies under General George H. Thomas, W. T. Sherman, and Joseph Hooker, November 25, 1863, drove Bragg from his perch on Missionary Ridge and to a precipitate retreat, and the Army of the Tennessee under Sherman subsequently relieved Burnside, besieged at Knoxville by Longstreet, thus closing the campaigns of 1863 in the West about the time they closed in the East. Soon thereafter rumors were current that Grant was to be promoted to chief command of all the Union armies. A law passed Congress February 29, 1864, reviving the grade of Lieutenant-General, and President Lincoln, the next day, appointed Ulysses S. Grant to the office, and the Senate, the succeeding day, confirmed the appointment. March 10, 1864, Halleck was relieved from duty as General-in-Chief, and became thereafter Chief of Staff of the Army. Grant was, the same day, assigned by the President, "pursuant to the act of Congress, to command the Armies of the United States," headquarters of the Army to be in Washington, and "with General Grant in the field." Grant established his field-headquarters at Culpeper Court-House, March 26, 1864, and remained with the Army of the Potomac until Appomattox came. Just prior to his joining the Army of the Potomac, March 23, 1864, it was reorganized, the First and Third Corps being broken up as separate organizations, and the troops composing them distributed to the Second, Fifth, and Sixth Corps, they retaining their former corps badges. Hancock resumed command of the Second Corps. Warren was assigned to command the Fifth. Carr was transferred to the Second. The Third Division, Third Corps, became the Third Division of the Sixth (Sedgwick's) Corps, the old Third Division of the Sixth being consolidated with its other divisions.
General H. Prince was assigned to command the Third Division of the Sixth. The Second Brigade (Keifer's) of this division, with the 126th Ohio (Colonel Smith) and the 67th Pennsylvania (Colonel Staunton) added, was placed under the command of General David A. Russell,(11) but he was soon transferred to another command, and Colonel B. F. Smith for a time succeeded him. Major-General James B. Ricketts, before April 30, 1864, relieved General Prince, and thereafter the Third Division of the Sixth Corps was known as "Ricketts' Division."
Much bad feeling existed on the part of Generals French, Sykes, Newton, and others over the breaking up of their commands and their being relieved from field duty. The consolidation of divisions and brigades in the corps retained, also caused much discontent, and excited jealousies towards the organizations from the disbanded corps which took their old designations. This was the second time troops I commanded had this experience. While in camp or on marches an officer may become disliked by his men, but a great battle in which he does his duty will always restore him to popularity. The Third Corps badge was a diamond; the Sixth a Greek cross. The Third Division for a time adhered to the diamond, but later, wore both proudly, and finally rejoiced alone under the Greek cross.
The Army of the Potomac was for the first time reduced to three corps. There was, however, belonging to this army, a large artillery reserve, not attached to any corps, but under a chief, General Henry J. Hunt; also a cavalry corps, consisting of three divisions and a reserve brigade, which Major-General Philip H. Sheridan was assigned (April 5, 1864) to command.(12) To each corps was attached an artillery brigade. This army, like any other well-appointed one, also had (each with a chief officer) its Commissary, Quartermaster, Ordnance, and Medical Departments; also a Provost-Guard, consisting of a brigade of infantry and a regiment of cavalry under a Provost Marshal-General;(13) also Signal and Engineer Corps, and other minor and somewhat independent organizations, such as body-guards to commanding generals, pioneers, pontoniers, etc.
The Army of the Potomac, thus organized, commanded, and appointed, with the new commander of all the armies of the Union with it, now awaited good weather to enter upon the bloodiest campaign civilized man has ever witnessed.
