HEADQUARTERS DEFENSES OF WASHINGTON,
September 11, 1862.
Commander-in-Chief, U. S. Army:
GENERAL: I have the honor to inclose to you a synopsis from the reports of the 10th instant of the forces in and near Washington for its defence. I t is as near to the exact strength as "reports" will bring us. The aggregate is probably somewhat larger than the actual number of troops ready for duty.
I have the honor to be, with much respect, your obedient servant,
N. P. BANKS,
