Richd C. Drum to James H. Carleton, March 14, 1862

Col. JAMES H. CARLETON, First Infantry California Volunteers,

SIR: Your disposition of the forces in the southern district is approved by the general commanding the department. The general court-martial requested in your letter of the 11th instant will be convened at as early a day as practicable. The general desires you to submit to the judge-advocate such charges of a capital nature as are in your possession. The activity and zeal displayed by Major Rigg at Fort Yuma are highly commendable, and show a knowledge of his business rarely to be found in an officer whose experience is so limited,

Very respectfully, your obedient servant,
