HEADQUARTERS FIFTH CORPS,
Near Sharpsburg, Md., October 5, 1862--8 p. m.

Brigadier General R. B. MARCY,

Chief of Staff, Headquarters Army of the Potomac:

GENERAL: It is reported to me that the enemy has planted two guns on the opposite bank of the Potomac within range of our batteries, and so posted as to sweep the ford. Also that their infantry has occupied the woods beyond the ford. To-morrow morning I shall take steps to obtain full information in the matter. Meanwhile every precaution will be observed to prevent any possibility of surprise. I have no doubt but that the movement is made with the design of preventing our cavalry from crossing the ford, as it has been in the habit of doing.

Very respectfully, your obedient servant,

F. J. PORTER,

Major-General, Commanding.
