FORT MONROE, May 7, 1863.

General GORDON, Yorktown:

(To be sent on board the Spaulding the moment she arrives.)

The cavalry will have gone ere you reach Yorktown. Push on to your destination. General Keyes has gone on to send off the cavalry at once to destroy the railroad bridge of which I spoke, and will see to the landing till you arrive. He will command the movement at present. I hope to be up by 3 p. m. After you left I found it was necessary to push up rapidly. A float for temporary wharf, materials for repairing the old one, intrenching tools, and all necessary supplies have gone. I am anxious that you should reach the point of landing as soon as the mass of your division.

JOHN A. DIX,

Major-General.
