+After the death of General Reynolds, General Hancock was assigned to the command of all the troops on the field of battle, relieving General Howard, who had succeeded General Reynolds. General Gibbon, of the Second Division, assumed command of the corps. These assignments terminated on the evening of July 1. Similar changes in commanders occurred during the battle of the 2d, when General Hancock was put in command of the Third Corps, in addition to that of his own. He was wounded on the 3d, and Brigadier General William Hays was assigned to the command of the corps.
