Brigadier-General.

Major-General HALLECK,

General-in-Chief:

Scouting parties went both yesterday and to-day from Point of Rocks within 1 1/2 miles of Leesburg, and report no enemy. A citizen at the point, from Leesburg, spoke of a rumor such as you name. I can learn of no crossing or attempt; certainly none this side of the Monocacy.
