The night of the 13th Warren and Wright were moved by the rear to the left of Burnside.  The night was very dark and it rained heavily, the roads were so bad that the troops had to cut trees and corduroy the road a part of the way, to get through.  It was midnight before they got to the point where they were to halt, and daylight before the troops could be organized to advance to their position in line.  They gained their position in line, however, without any fighting, except a little in Wright’s front.  Here Upton had to contend for an elevation which we wanted and which the enemy was not disposed to yield.  Upton first drove the enemy, and was then repulsed in turn.  Ayres coming to his support with his brigade (of Griffin’s division, Warren’s corps), the position was secured and fortified.  There was no more battle during the 14th.  This brought our line east of the Court House and running north and south and facing west.

During the night of the 14th-15th Lee moved to cover this new front.  This left Hancock without an enemy confronting him.  He was brought to the rear of our new centre, ready to be moved in any direction he might be wanted.

On the 15th news came from Butler and Averill.  The former reported the capture of the outer works at Drury’s Bluff, on the James River, and that his cavalry had cut the railroad and telegraph south of Richmond on the Danville road:  and the latter, the destruction of a depot of supplies at Dublin, West Virginia, and the breaking of New River Bridge on the Virginia and Tennessee Railroad.  The next day news came from Sherman and Sheridan.  Sherman had forced Johnston out of Dalton, Georgia, and was following him south.  The report from Sheridan embraced his operations up to his passing the outer defences of Richmond.  The prospect must now have been dismal in Richmond.  The road and telegraph were cut between the capital and Lee.  The roads and wires were cut in every direction from the rebel capital.  Temporarily that city was cut off from all communication with the outside except by courier.  This condition of affairs, however, was of but short duration.

I wrote Halleck: 

NEAR SPOTTSYLVANIA C. H., May 16, 1864, 8 A.M.

MAJOR-GENERAL HALLECK, Washington, D. C.: 

We have had five days almost constant rain without any prospect yet of it clearing up.  The roads have now become so impassable that ambulances with wounded men can no longer run between here and Fredericksburg.  All offensive operations necessarily cease until we can have twenty-four hours of dry weather.  The army is in the best of spirits, and feel the greatest confidence of ultimate success. * * * * * * You can assure the President and Secretary of War that the elements alone have suspended hostilities, and that it is in no manner due to weakness or exhaustion on our part.

U. S. GRANT, Lieut.-General.
