BALTIMORE MD., June 17, 1863.

Brigadier General B. F. KELLEY,

New Creek, W. Val:

Can you have the track between New Creek and Cumberland repaired, or without it go down upon Imboden? Some portion of the raid may, perhaps, go over the mountains south of you, or Imboden may take the National road. Averell should leave a watch at the gap south of Grafton, and a nucleus of his command at Grafton, with means of transportation by railroad or land between.

ROBT. C. SCHENCK,

Major-General.

BALTIMORE, MD., June 17, 1863-7 p. m.

Major-General HALLECK:

Imboden, with his forces, may intend to push across through Uniontown, Pa., by the National road to Wheeling. I am looking to that, among other contingencies. There should be a gunboat at Wheeling, one also at Parkersburg, and one on the Kanawha. While Averell keeps the nucleus of his command for concentration at Grafton, I have directed that he shall have cavalry watching the passes westward through the mountains at Beverly and elsewhere. I have instructed Kelley, at New Creek, to look after Imboden.

ROBT. C. SCHENCK,

Major-General.
