Lieutenant-Colonel RICHMOND,
Assistant Adjutant-General:

COLONEL: I have the honor to report that there was very little picket-firing in my front last night. The Twenty-fourth New York Cavalry and Fifty-first Pennsylvania are withdrawn from the lines, and will furnish details for pickets, &c.

[General BURNSIDE:]

Very respectfully,
O. B. WILLCOX,

Brigadier-General.
