HDQRS. ENGINEER DEFENSES, DEPT. OF N. VIRGINIA,
July 4, 1863.
Colonel J. F. GILMER,
Chief of Engineers:
COLONEL: Yesterday I sent you my correspondence about getting free negroes from Richmond. It is desirable to urge this matter, as I deem it important to fill up the gap on Mechanicsville road on intermediate line as soon as possible. A prompt action of the city authorities, constables, &c., would undoubtedly in a day or two secure us upward of 500 negroes, if not more.
Very respectfully, your obedient servant,
W. H. STEVENS,
Colonel of Engineers.
ENGINEER BUREAU, July 4, 1863.
Respectfully referred to the honorable Secretary of War with and earnest recommencdation that His Excellency the Governor, the mayor, vigorous defense of Richmond, should the enemy attempt an advance in force on this city. The gap in the best line of defense near the crossing of the Mechanicsville road should be closed at the earliest day possible. Brigadier-General Jenkins is putting his soldier on fatigue duty; so are other commanders, but all the labor that can be had is wanted.
J. F. GILMER,
Colonel of Engineers and Chief of Bureau.

You will have them loaded with as many of the wounded as they will carry, and let them give out to every one that they are going gack with the wounded and for ammunition. You will also have three days' cooked rations for all the men of your command provited to-night to be carried in their haversacks, and retain enough wagons to carry one day's more, which you will carry.
