Telegram To General J. Hooker.

Washington, D. C. May 8, 1863. 4 P.M.

MAJOR-GENERAL HOOKER:

The news is here of the capture by our forces of Grand Gulf—a large and very important thing. General Willich, an exchanged prisoner just from Richmond, has talked with me this morning. He was there when our cavalry cut the roads in that vicinity. He says there was not a sound pair of legs in Richmond, and that our men, had they known it, could have safely gone in and burned everything and brought in Jeff Davis. We captured and paroled 300 or 400 men. He says as he came to City Point there was an army three miles long (Longstreet's, he thought) moving toward Richmond.

Muroy has captured a despatch of General Lee, in which he says his loss was fearful in his last battle with you.
