Here, at "Bloody Lane" in the sunken road, was delivered the most telling blow of which the Federals could boast in the day's fighting at Antietam, September 17, 1862. In the lower picture we see the officers whose work first began to turn the tide of battle into a decisive advantage which the Army of the Potomac had every reason to expect would be gained by its superior numbers. On the Federal right Jackson, with a bare four thousand men, had taken the fight out of Hooker's eighteen thousand in the morning, giving ground at last to Sumner's fresh troops. On the Federal left, Burnside (at the lower bridge) failed to advance against Longstreet's Corps, two-thirds of which had been detached for service elsewhere. It was at the center that the forces of French and Richardson, skilfully fought by their leaders, broke through the Confederate lines and, sweeping beyond the sunken road, seized the very citadel of the center. Meagher's Irish Brigade had fought its way to a crest from which a plunging fire could be poured upon the Confederates in the sunken road. Meagher's ammunition was exhausted, and Caldwell threw his force into the position and continued the terrible combat. When the Confederates executed their flanking movement to the left, Colonel D. R. Cross, of the Fifth New Hampshire, seized a position which exposed Hill's men to an enfilading fire. (In the picture General Caldwell is seen standing to the left of the tree, and Colonel Cross leans on his sword at the extreme right. Between them stands Lieut.-Colonel George W. Scott, of the Sixty-first New York Infantry, while at the left before the tent stands Captain George W. Bulloch, A. C. S. General Caldwell's hand rests on the shoulder of Captain George H. Caldwell; to his left is seated Lieutenant C. A. Alvord.) [Illustration: BRIGADIER-GENERAL CALDWELL AND STAFF] [Illustration: SHERRICK'S HOUSE COPYRIGHT, 1911, PATRIOT PUB. CO.] In three distinct localities the battle waxed fierce from dawn to dusk on that terrible day at Antietam, September 17, 1862. First at the Federal right around the Dunker church; then at the sunken road, where the centers of both armies spent themselves in sanguinary struggle; lastly, late in the day, the struggle was renewed and ceased on the Sharpsburg road. When Burnside finally got his troops in motion, Sturgis' division of the Ninth Corps was first to cross the creek; his men advanced through an open ravine under a withering fire till they gained the opposite crest and held it until reënforced by Wilcox. To their right ran the Sharpsburg road, and an advance was begun in the direction of the Sherrick house. [Illustration: GENERAL A. P. HILL, C. S. A.]
