You must keep the cavalry scouting in your front. Send to Frederick, and communicate with General Stahel. He was directed to keep you advised of what is going on in your front. My headquarters will be here to-night, and I will move up all the corps together, so as to concentrate at Middletown or in that neighborhood. Yours, &c.,

Major-General REYNOLDS:

I arrived at this place this afternoon, and have made the following disposition of my troops: I have one brigade and one section of artillery at Crampton's Pass, patrolling thoroughly on the other side, but without meeting with any enemy whatever; they are supported by one brigade and two sections of artillery of the Eleventh Corps. I have one regiment in South Mountain Pass, patrolling in that vicinity, but without meeting any of the enemy. One brigade and two sections of artillery are at Middletown, and two regiments about 2 miles from this place, on the road leading toward Lewistown. As was stated by telegraphic dispatch of last evening, there is no enemy in the neighborhood of any of the gaps, nor do they seem to have any intention of coming this side. There was a small force of rebel cavalry at Boonsborough this morning, but there are none of them there now. The whole rebel army is marching toward Harrisburg. Ewell's whole corps passed thorough Hagerstown and Smithsburg last Tues-
