Richd. C. Drum to George S. Evans, June 18, 1862

Lieut. Col. GEORGE S. EVANS, Second Cavalry California Volunteers, Camp Latham, Cal.: SIR: The superintendent of Indian affairs for the southern district of California is at this time on a visit to the Indian reservations in his district. Should he call upon you for a force to remove intruders from the reservations, the general commanding the department desires you to send a party from your command sufficiently strong for that purpose. You will direct the officers in charge of any detachments to report for instructions to the superintendent.

Very respectfully, your obedient servant,
