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--8.3O 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.
The arrival of reinforcements here will be very encouraging to the men, and I hope they will be sent as fast as possible, and in as great numbers. My object in having them sent to Belle Plain was to use them as an escort to our supply trains. If it is more convenient to send them out by train to march from the railroad to Belle Plain or Fredericksburg, send them so.
I am satisfied the enemy are very shaky, and are only kept up to the mark by the greatest exertions on the part of their officers, and by keeping them intrenched in every position they take.
Up to this time there is no indication of any portion of Lee's army being detached for the defence of Richmond.
U. S. GRANT, Lieut.-General.
And also, I received information, through the War Department, from General Butler that his cavalry under Kautz had cut the railroad south of Petersburg, separating Beauregard from Richmond, and had whipped Hill, killing, wounding and capturing many. Also that he was intrenched, and could maintain himself. On this same day came news from Sheridan to the effect that he had destroyed ten miles of the railroad and telegraph between Lee and Richmond, one and a half million rations, and most of the medical stores for his army.
On the 8th I had directed Sheridan verbally to cut loose from the Army of the Potomac and pass around the left of Lee's army and attack his cavalry and communications, which was successfully executed in the manner I have already described.
