I Corps had been so significantly damaged at Gettysburg that, when the Army of the Potomac was reorganized in March 1864, its surviving regiments were dispersed to other corps. After an eight-month leave of absence, much of it spent inspecting colored troops on duty in the Mississippi Valley, Wadsworth was named commander of the 4th Division, V Corps, composed of troops from his old division and that formerly led by Maj. Gen. Abner Doubleday. This speaks well for his performance at Gettysburg, because a number of his contemporaries were left without assignments when the army reorganized or were sent to minor assignment elsewhere.
