CUMBERLAND, MD., April 17, 1864-11. 30 p. m.

(Received 10. 50 a. m., 18th.)

Brigadier General J. A. RAWLINS,

Chief of Staff:

Please inform the general that General Sigel has telegraphed to General Crook for some information, but cannot obtain it before morning, as the wires are down. Soon as the information is received General Sigel will telegraph in full. General Sigel reports that he needs at once at least 2,500 horses for the old regiments, and soon as available some 4,000 for the new and veteran regiments. If the 2,500 cannot be obtained at once it will materially cripple the anticipated movement. General Sigel asks if something cannot be done. His chief quartermaster has asked the Cavalry Bureau for permission to pay $153 and to purchase a portion of mares at proper prices.

Lieutenant-Colonel and Aide-de-Camp.
