My men were fatigued from their fighting to-day, and ammunition exhausted. I have therefore concluded to halt for the night, recruit men and horses, get ammunition and provisions, so as to push out at the first dawn of day. I shall leave two regiments to patrol from the right of the army to the river.

Having no appliances for the destruction of bridges, would it not be well to send me a half dozen barrels of powder and some slow match. If you do so, it should be here before 3.30 a. m. My officers and men have behaved with great gallantry this afternoon. Colonel McIntosh deserves promotion as one of the most competent brigade commanders in the army.

I am, sir, very respectfully, your obedient servant,

J. H. WILSON,

Brigadier-General.

Major General A. A. HUMPHREYS,

Chief of Staff, Army of the Potomac.
