The morning of the 12th opened foggy, delaying the start more than half an hour.

The ground over which Hancock had to pass to reach the enemy, was ascending and heavily wooded to within two or three hundred yards of the enemy's intrenchments. In front of Birney there was also a marsh to cross. But, notwithstanding all these difficulties, the troops pushed on in quick time without firing a gun, and when within four or five hundred yards of the enemy's line broke out in loud cheers, and with a rush went up to and over the breastworks. Barlow and Birney entered almost simultaneously. Here a desperate hand-to-hand conflict took place. The men of the two sides were too close together to fire, but used their guns as clubs. The hand conflict was soon over. Hancock's corps captured some four thousand prisoners among them a division and a brigade commander twenty or more guns with their horses, caissons, and ammunition, several thousand stand of arms, and many colors. Hancock, as soon as the hand-to-hand conflict was over, turned the guns of the enemy against him and advanced inside the rebel lines. About six o'clock I ordered Warren's corps to the support of Hancock's. Burnside, on the left, had advanced up east of the salient to the very parapet of the enemy. Potter, commanding one of his divisions, got over but was not able to remain there. However, he inflicted a heavy loss upon the enemy; but not without loss in return.
