Franz Sigel to Robert E. Lee, July 5, 1864

(Via Frederick, Md. Received 3.25 p. m.) Before my troops arrived at Harper’s Ferry, General Weber at 6.30 p. m. yesterday evacuated Harper’s Ferry to occupy Maryland Heights. My troops arrived at Sandy Hook at 8 p. m., and took position on Maryland Heights, the cavalry remaining at or near everton. It wasordered toward Point of Rocks to operate against the enemy that crossed there. The enemy that attacked Harper’s Ferry was of Ewell’s corps, so reported by Generat Weber; the strength not developed. About 7,000 of the enemy occupied Martinsburg after our evacuation, and a force of rebel cavalry crossed at Williamsport yesterday. I have sent the train from Martinsburg to Frederick, as it could be of no use to us nearer to Harper’s Ferry after its evacuation. No stores of any kind were lost at Harper’s Ferry. We have sufficient subsistence stores and ammunition—the former for twenty days. Further information will be promptly forwarded.

F. SIGEL,
