GENERAL ORDERS, No 174 WAR DEPARTMENT, Adjutant General’s Office, Washington, April 22, 1*64. Employment of Cavalry organizations not mounted. Cavalry organizations which cannot immediately be supplied with horses, will be armed and employed temporarily as Infantry. They may be used to guard depots and railroads, or be assigned to Infantry brigades in the field. When regiments so assigned are partially mounted, the horses will be transferred to others. Commanders of departments and separate armies are authorized to dismount and employ as Infantry any Cavalry regiment which has been neglectful or wasteful of its horses, or has proved inefficient in the field, and transfer its horses to others. The proportion of Cavalry to be temporarily converted into Infantry will not exceed forty per cent, of any command, unless it be found that the remaining sixty per cent, cannot be kept efficiently mounted. order of the Secretary of War: E. D. TOWNSEND, Assistant Adjutant General. Official : Assistant Adjutant General,
