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withdrawn.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.

Burnside on the left had got up to within a few hundred yards of
Spottsylvania Court House, completely turning Lee's right. He was not
aware of the importance of the advantage he had g
