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  At night they were withdrawn.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 gained, and I, being with the troops where the heavy fighting was, did not know of it at the time.  He had gained his position with but little fighting, and almost without loss.  Burnside’s position now separated him widely from Wright’s corps, the corps nearest to him.  At night he was ordered to join on to this.  This brought him back about a mile, and lost to us an important advantage.  I attach no blame to Burnside for this, but I do to myself for not having had a staff officer with him to report to me his position.

The enemy had not dared to come out of his line at any point to follow up his advantage, except in the single instance of his attack on Barlow.  Then he was twice repulsed with heavy loss, though he had an entire corps against two brigades.  Barlow took up his bridges in the presence of this force.

On the 11th there was no battle and but little firing; none except by Mott who made a reconnoissance to ascertain if there was a weak point in the enemy’s line.

I wrote the following letter to General Halleck: 

NEAR SPOTTSYLVANIA C. H., May 11, 1864—­8.30 A.M.

MAJOR-GENERAL HALLECK, Chief of Staff of the Army, Washington, D. C.

We have now ended the 6th day of very hard fighting.  The result up to this time is much in our favor.  But our losses have been heavy as well as those of the enemy.  We have lost to this time eleven general officers killed, wounded and missing, and probably twenty thousand men.  I think the loss of the enemy must be greater—­we having taken over four thousand prisoners in battle, whilst he has taken from us but few except a few stragglers.  I am now sending back to Belle Plain all my wagons for a fresh supply of provisions and ammunition, and purpose to fight it out on this line if it takes all summer.
