His position was in a field near a farm-house, where the Rebels had thrown up a square redoubt, which they had abandoned. From the farm-house to the woods west of it there was a rail-fence. Hancock threw out his skirmishers towards Fort Magruder, beyond the farm-house. Wheeler's battery was brought up and placed upon a knoll near the house. The Fifth Wisconsin and Forty-Third New York were stationed west of the house behind the fence. The Forty-ninth Pennsylvania was placed behind the house. Two companies of the Sixth Maine held the abandoned redoubt, while the other companies of that regiment were placed in support of the battery. Two brigades of Rebels marched out from the forest into the field. Wheeler's battery opened with shells. The Rebels were half a mile distant, but, notwithstanding the fire, they moved steadily and rapidly over the intervening space. The skirmishers which had been thrown out from Hancock returned to the lines. The Rebels were near enough for canister, and the six pieces of cannon threw it into the advancing line. The Rebel cavalry dashed upon the Fifth Wisconsin, but only to lose a dozen men and horses. The infantry were close upon Wheeler, who covered the hillock with a murky cloud. Suddenly his fire ceased, then with whip and spur and shout the pieces went to the rear and took a new position and opened again. The regiments by the fence fell back and closed up in closer order. The Rebels again advanced, and the musketry began. The fight was at short range. The battery fired shell, canister, and shrapnel, and made terrible havoc. Hancock saw that the moment for decisive action had come. He waved his cap to his troops. The officers along the line understood the meaning of the signal. They spoke but one magical word. The men, as if animated by an electric impulse, moved towards the enemy. Their bayonets became a gleaming, glittering, bristling, moving hedge. They broke into a run. Each man felt the enthusiasm of the moment. They heeded not the deadly volleys, but went on through the storm, with a cheer louder than the roar of the battle. The Rebels did not wait to receive the blow, but fled in confusion from the field. It was a glorious moment. Berry at that instant was throwing in a living barrier against the flood which had swept Hooker back. The battle was won. Night came on. It had rained through the day, and the men, victorious at last, lay down to sleep upon the field, while the Rebels fled towards Richmond, leaving several cannon, many wagons, and several hundred of their wounded in Williamsburg. The total Union loss was two thousand two hundred and eighty-eight. The loss to the Rebels was from two thousand five hundred to three thousand. "Our loss amounted to about two thousand five hundred," says the chaplain of the Fourth Texas.
