Major General H. W. HALLECK:

There is no reasonable doubt that the enemy have passed through Rockville. Negroes and citizens so report, and trains moving to the northwest during the night. A negro reports that their advance passed Rockville at daylight this morning.

Major-General AUGUR,

Fort Stevens, D. C.:

General Wright's forces should immediately move out on the river road from Tennallytown, and Gillmore follow as soon as possible. Fifteen hundred more of the Nineteenth Corps are coming up, and I have ordered them to be supplied as soon as landed. Cavalry should move up River road to reconnoiter and report; also cavalry on the south side should move up and ascertain the condition of affairs on that side.
