At six o'clock the advance was ordered. The enemy were taken by surprise and fled after a brief resistance. General Rodes's men pushed forward with great vigor and enthusiasm, followed closely by the second and third lines. Position after position was carried, the guns captured, and every effort of the enemy to rally defeated by the impetuous rush of our troops. In the ardor of pursuit through the thick and tangled woods, the first and second lines at last became mingled and moved on together as one. The enemy made a stand at a line of breastworks across the road at the house of Melzi Chancellor, but the troops of Rodes and Colston dashed over the entrenchments together and the flight and pursuit were resumed and continued until our advance was arrested by the abatis in front of the line of works near the central position at Chancellorsville. It was now dark, and General Jackson ordered the third line, under General Hill, to advance to the front and relieve the troops of Rodes and Colston, who were completely blended, and in such disorder, from their rapid advance through intricate woods and over broken ground, that it was necessary to reform them. As General Hill's men moved forward, General Jackson, with his staff and escort, returning from the extreme front, met his skirmishers advancing, and in the obscurity of the night were taken for the enemy and fired upon. Captain J. K. Boswell, chief engineer of the corps and several others were killed and a number wounded. General Jackson himself received a severe injury and was borne from the field. He was taken to the Chandler house, at Guiney's station, in Caroline county, where, notwithstanding everything possible was done for him that loving hearts could do or medical skill could suggest, he died on the 9th of May. Amid the sorrow and tears of the Southern people he was laid to rest at his home in Lexington, Virginia. General Jubal A. Early had been left at Fredericksburg to watch General Sedgwick, and had been instructed, in the event of the enemy withdrawing from his front and moving up the river, to join the main body of the army. This order was repeated on the 2nd, but by some mistake General Early was directed to move unconditionally. Leaving Hays's brigade and one regiment of Barksdale's at Fredericksburg, he moved with the rest of his command towards Chancellorsville. As soon as his withdrawal was perceived the enemy began to advance, and General Early returned to his original position. The line to be defended by Barksdale's brigade extended from the Rappahannock, above Fredericksburg, to the rear of Howison's house, a distance of more than two miles. The artillery was posted along the heights in rear of the town.
