As the remnants of Hooker's command sought shelter under the cover of powerful Federal batteries in front of East Woods, a new threat faced the Confederates. Mansfield's XII Corps, which had encamped more than a mile to the rear of Hooker during the night, had marched at the sound of Hooker's opening guns. At 7:30 a.m., almost an hour and a half later, Mansfield's force was approaching from the north in heavy columns. | As the remnants of Hooker's command sought shelter under the cover of powerful Federal batteries in front of East Woods, a new threat faced the Confederates.
