October 10, 1862-2 p. m.

Brigadier-General MARCY,

Chief of Staff, army of the Potomac:

Major Linton reports from Cherry Run that the rebels are crossing into Maryland at McCoy's Ferry. A refugee reports the force at 16,000, probably exaggerated. I have directed Major Linton to ascertain the strength and composition of the force. Reports to the same effect come from Hancock. Cox's brigade will be got off from there to-night if nothing happens to the road, I have a line of cavalry pickets nearly completed, extending from New Creek to cherry Run, from McReynolds' command, and from McCoy's Ferry to Falling Waters, from my own. One the other side, I have scouts hovering about, to whom I shall turn my attention as soon as I can

get the picket lines well extended.
