Birney was now moved to the high ground overlooking the river crossings built by our troops, and covered the crossings. The second assault was repulsed, again with severe loss to the enemy, and Barlow was withdrawn without further molestation.
General T. G. Stevenson was killed in this move.
Between the lines, where Warren's assault was to take place, there was a ravine grown up with large trees and underbrush, making it almost impenetrable by man. The slopes on both sides were also covered with a heavy growth of timber. Warren, before noon, reconnoitred his front twice, the first time with one and the second with two divisions. He was repulsed on both occasions, but gained such information of the ground as to induce him to report recommending the assault.
Wright also reconnoitred his front and gained a considerably advanced position from the one he started from. He then organized a storming party, consisting of twelve regiments, and assigned Colonel Emory Upton, of the 121st New York Volunteers, to the command of it. About four o'clock in the afternoon the assault was ordered, Warren's and Wright's corps, with Mott's division of Hancock's corps, to move simultaneously. The movement was prompt, and in a few minutes the fiercest of struggles began. The battle-field was so densely covered with forest that but little could be seen, by any one person, as to the progress made. Meade and I occupied the best position we could get, in rear of Warren.
Warren was repulsed with heavy loss, General J. C. Rice being among the killed. He was not followed, however, by the enemy, and was thereby enabled to reorganize his command as soon as covered from the guns of the enemy. To the left our success was decided, but the advantage was lost by the feeble action of Mott. Upton with his assaulting party pushed forward and crossed the enemy's intrenchments. Turning to the right and left he captured several guns and some hundreds of prisoners.
Mott was ordered to his assistance but failed utterly. So much time was lost in trying to get up the troops which were in the right position to reinforce, that I ordered Upton to withdraw; but the officers and men of his command were so averse to giving up the advantage they had gained that I withdrew the order. To relieve them, I ordered a renewal of the assault. By this time Hancock, who had gone with Birney's division to relieve Barlow, had returned, bringing the division with him. His corps was now joined with Warren's and Wright's in this last assault. It was gallantly made, many men getting up to, and over, the works of the enemy; but they were not able to hold them. At night they were withdrawn. Upton brought his prisoners with him, but the guns he had captured he was obliged to abandon. Upton had gained an important advantage, but a lack in others of the spirit and dash possessed by him lost it to us. Before leaving Washington I had been authorized to promote officers on the field for special acts of gallantry. By this authority I conferred the rank of brigadier-general upon Upton on the spot, and this act was confirmed by the President. Upton had been badly wounded in this fight.
