 When the III Corps was discontinued in the spring of 1864, its 1st Division, which had once been Joe Hooker's command, became the 4th Division of the II Corps, now commanded by Mott.The III Corps veterans were not happy with the disappearance of their outfit and morale consequently suffered.The division was driven from the field in panic during the fighting in the Wilderness, and both II Corps commander Maj. Gen Winfield Hancock and 1st Division commander Maj. Gen Francis Barlow held an extremely low opinion of them.
