ALEXANDRIA DEPOT, September 24, 1863.

(Received 10 p.m.)

Hon. E. M. STANTON,

Secretary of War:

SIR: I thank you for the caution. I saw the necessity of being silent on the subject referred to in your dispatch. In consequence of the insufficiency of the side track where the Eleventh Corps is now located, General Howard will march the troops to Manassas Junction. This arrangement will facilitate matters very much. This morning about 11 o'clock a band of 21 mounted guerrillas made a dash at our wood teams, about 13 miles from Alexandria, on the line of the road, capturing 9 mules, and wounding and capturing a sergeant of the guard.

Very respectfully, &c.,

D. C. McCALLUM,

Colonel, &c.

BALTIMORE, September 24, 1863.

Your telegram of 8 p.m. yesterday+ has been referred for answer to Major-General Hooker. Willard's Hotel, who has been placed in command of the Eleventh and Twelfth Corps.
