e 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.

The condition of the roads was such that nothing was done on the 17th.
But that night Hancock and Wright were to make a night march back to
their old positions, and to make an assault at four o'clock in the
morning. Lee got troops back in time to protect his old line, so the
assault was unsuccessful. On this day (18th) the news was almost as
discouraging to us as it had been two days before in the rebel capital.
As stated above, Hancock's and Wright's corps had made an unsuccessful
assault. News came that Sigel had been defeated at New Market, badly,
and was retreating down the valley. Not two hours before, I had sent
the inquiry to Halleck whether Sigel could not get to Staunton to stop
supplies coming from there to Lee. I asked at once that Sigel might be
relieved, and some one else put in his place. Hunter's name was
suggested, and I heartily approved. Further news from Butler reported
him driven from Drury's Bluff, but still in possession of the Petersburg
road. Banks had been defeated in Louisiana, relieved, and Canby put in
his place. This change of commander was not on my suggestion. All this
news was very discouraging. All of it must have been known by the enemy
before it was by me. In fact, the good news (for the enemy) must have
been known to him at the moment I thought he was in despair, and his
anguish had been already relieved when we were enjoying his supposed
discomfiture, But this was no time for repining. I immediately gave
orders for a movement by the left flank, on towards Richmond, to
commence on the night of the 19th. I also asked Halleck to secure the
cooperation of the navy in changing our base of supplies from
Fredericksburg to Port Royal, on th
