James H. Carleton to R. C. Drum, March 29, 1862

Mai, R. C. DRUM, U.S. Army, Assistant Adjutant-General, San Francisco, Cal. : MAJOR: Ishall send the two mountain howitzers now at Camp Latham to the sub-depot to be established at the Pima Villages. They are nearly destitute of ammunition of all kinds, save some forty-eight rounds of spherical case-shot, and, say, ten roundsof canister. I need for them an adequate supply of fixed ammunition, consisting of shells, spherical case-shot, and canister, with fuses, friction-tubes, portfires, Se. Please order this ammunition down on the return Senator, and write to me that you have done so, that I may know it is on board when the boat comes.

Very respectfully, your obedient servant,
