HEADQUARTERS FIFTH CORPS, Union Mills,
June 30, 1863-6. 30 p. m.

General S. WILLIAMS:

Barnes and Ayres are here. I expect the artillery soon. Crawford cannot get here to-night, and I have directed him to march till dark, and encamp between Frizellburg and this place. No enemy about. Stuart, Fitz. Lee, and Hampton staid last night at the house of a Mr. Shriver, who owns the mill at this place. They left here this morning between 4 and 10 a. m., some toward Hanover and some toward Littlestown, but I take it all have gone toward Hanover. Their force is said to be about 5, 000, with six guns. They are taking horses, &c. General Crawford's men must have marched to-day in the neighborhood of 25 miles. I have not had the corps concentrated since leaving Fredericksburg. My troops are very foot-sore and tired. My aide, Lieutenant [George T.] Ingham, bears this dispatch.

I am, sir, respectfully,

GEO. SYKES,

Major-General, Commanding.
