Next day the two armies lay in their trenches facing each other in grim silence. Grant determined again to turn Lee's right flank and get between him and Richmond. Lee divined his purpose before a single regiment had begun to march. Spottsylvania Court House lay on his right. The Confederate Commander hurried his advance guard to the spot and lay in wait for his opponent. The day of the 19th was spent by both armies in adjusting lines and constructing breastworks. These fortifications were made by digging huge ditches and on the top of their banks fastening heavy logs. In front of these, abatis were made by filling the trees and cutting their limbs in such a way that the sharp spikes projected toward the breasts of the advancing foe. While placing his guns in position General Sedgwick was killed by a sharpshooter's bullet--a commander of high character and fearless courage and loved by every man in his army. On the morning of the 10th Hancock attempted to turn Lee's rear by crossing the Po. The movement failed and he was recalled with heavy losses under Early's assault as he recrossed the river. Warren led his division in a determined charge on the Confederate front and they were mowed down in hundreds by Longstreet's men behind their entrenchments. They reached the abatis and one man leaped on the breastworks before they fell back in bloody confusion. General Rice was mortally wounded in this charge. On the left of Warren, Colonel Emory Upton charged and broke through the Confederate lines capturing twelve hundred prisoners, but was driven back at last with the loss of a thousand of his men. Grant made him a Brigadier General on the field. The first day at Spottsylvania ended with a loss of four thousand Union men. Lee's losses were less than half that number. The 11th they paused for breath, and Grant sent his famous dispatch to Washington: "I propose to fight it out on this line if it takes all summer." On the morning of the 12th Hancock was ordered to charge at daylight. Lee's lines were spread out in the shape of an enormous letter V. Hancock's task was to capture the angle which formed the key to this position. In pitch darkness under pouring rain his four divisions under Birney, Mott, Barlow and Gibbon slipped through the mud and crept into position within a few hundred yards of the Confederate breastworks. As the first streaks of dawn pierced the murky clouds, without a shot, the solid, silent lines of blue rushed this angle and leaped into the entrenchments before the astounded men in grey knew what had happened. So swift was the blow, so surprising, so overwhelming in numbers, the angle was captured practically without a struggle and the three thousand men within it were forced to surrender with every cannon, their muskets, colors and two Generals. It was the most brilliant single achievement of "Hancock the Superb."
