[Illustration: BATTLE OF WILLIAMSBURG. 1 Hooker. 2 Hancock. 3 Sumner. 4 Longstreet. 5 Hill. 6 Fort Magruder. 7 Williamsburg.] General Hooker's skirmishers, as soon as they saw the enemy, dashed on and drove them across the ravine, and approached within musket-shot of the fort. The artillery in the fort opened with a rapid fire of shells, but the skirmishers concealed themselves in the underbrush, and gave so deadly a fire that they silenced the guns. No gunner could show his head without getting a ball through it. General Hooker formed his division in line of battle. His first brigade was commanded by General Sickles, and was composed of the First, Second, Third, Fourth, and Fifth Excelsior regiments from New York. His second brigade, General Grover's, was composed of the First and Eleventh Massachusetts, Second New Hampshire, and Twenty-sixth Pennsylvania. The third brigade was composed of the Fifth, Sixth, Seventh, and Eighth New Jersey regiments, and was commanded by Colonel Starr,--in all, about eight thousand men. The First Massachusetts had the left of the line, then the Second New Hampshire, Eleventh Massachusetts, with the Twenty-sixth Pennsylvania on the right. The other brigades did not arrive till nearly noon. They formed on the left of Grover's brigade, towards the mill-pond. The Rebel force in position behind the forts is supposed to have been about thirty thousand, commanded by General Longstreet. A Rebel officer states that it numbered not over twenty-five thousand.[18] [Footnote 18: Battle-Fields of the South, by an English Officer in the Confederate Army. London.] During the forenoon but a small force confronted General Grover's brigade, but in the afternoon dark columns appeared south of the fort, and, advancing down the ravines, crossed the stream above the mill-pond. They attacked General Hooker's left wing in great force. The skirmishers were driven in. Bramhall's battery came into position as the enemy advanced. "Shell with short fuses!" shouted the captain to his gunners. The shells exploded in, around, and above the advancing columns, which still kept coming on. The musketry began,--quick and sharp volleys; yet the lines came on, across the open space, through the woods. "Canister and spherical case!" was the order to the gunners. The cannon spouted a deadly fire, filling the air with terrible hail. The Rebel lines were checked. Foiled in the attack upon the center, they advanced once more upon the left flank, and the contest went on with increasing fury, like the rising of a winter tempest. Grover and Sickles held their ground tenaciously, but were forced back inch by inch and step by step.
