James H. Carleton to R. Drum, U. S. Army, February 7, 1862
Maj. R. ©. DRUM, U. S. Army, Assistant Adjutant-General, San Francisco, Cal. :
MAJOR: I understood from Captain Kirkham that at or about this time a brig would leave San Francisco laden with Government stores for Fort Yuma. Please do me the favor to let me know the name of this brig and with what cargo she is laden. This information is important to my movements, as I shall have an expressman leave Fort Yuma to notify me of the arrival of the vessel at the mouth of the Colorado; and I can tell exactly the state of the supplies for the Mojave expedition when her cargo comes to hand. I think it would be well for Colonel Bowie to be here at as early a day as practicable to discipline his regiment, five companies of which are now at Camp Latham.
Respectfully, your obedient servant,
Colonel First California Volunteers, Commanding.
