Colonel C. G. SAWTELLE,

Quartermaster, Washington, D. C.:

General Stoneman will cross to-morrow at Edwards Ferry. His supplies must be sent by canal to that point or near by, where the boats can be unlocked into the Potomac and cross to the turnpike at Goose Creek. See that the clothing, forage, and subsistence is forwarded. Send clothing as fast as possible to our depots higher up, as will be indicated by me. Forward your supplies by the readiest and most expeditions routes.

Captain Thomas has a list of much clothing yet to be sent. Blankets, shoes, stockings, pants, tents, &c., are first wanted.
