excepting by this garrison. I submit to you if the forces at Sharpsburg should not be at Martinsburg. Guerrillas are known to be in the Valley and in Loudoun County. White and Mosby were at more and Ohio Railroad in Frederick County. There seems to be a want of co-operation on our part, which enables this contemptible body of irregulars to exist notwithstanding the presence on our part of four times their force. Last night I was summoned to the aid of Captain Means, at Point of Rocks, by these forces. I am confident that proper active co-operation only is required to bring them to grief. Cavalry is much needed at Harper's Ferry.

Col A. J. Alexander,
Chief of Staff Corps:
I have been compelled to move closer to the river than I wished, on account of water. The whole division is now within a mile of the bridge, on both sides of the railroad. The rebel pickets are within 1 1/2 miles of the division. Yesterday was a very severe day upon men and horses. I myself am worthless.
