By order of General Meade, I have just assumed command of the defenses of Maryland Heights and vicinity. Can you inform me whether I am to regard myself as in your department and to report to you direct?

Lieutenant Colonel C. G. SAWTELLE,
Acting Chief Quartermaster:

COLONEL: I have the honor to inform you that there are at present 400 dismounted men in camp here; 200 men are expected to-day, and no doubt many more will reach here in a few days from the surrounding country. I think, therefore, that 700 will cover all that will be required to be mounted here.

HDQRS. U. S. FORCES (LATE MILROY'S DIVISION), Sharpsburg, Md., July 18, 1863.

Brigadier General S. WILLIAMS,
Assistant Adjutant-General, Army of the Potomac:

GENERAL: Up to 8 o'clock this morning no general officer had reached Hagerstown. I am still acting under the original orders. Is this correct? General Kelley has crossed at Cherry Run. Fitzhugh Lee, with a force of cavalry, infantry, and artillery, supposed to number 5, 000, was at Shepherdstown yesterday. I was prepared for him, but he kept out of range. I notified General Kelley.

AND'W T. McREYNOLDS,
