Unknown to R. W. Kirkham, April 11, 1862

Capt. R. W. KIRKHAM, Acting Assistant Adjutant-General, San Francisco, Cal.: CAPTAIN: Inclosed herewith please find copies of Major Riggs letters + to these headquarters, which will give the general the last

intelligence from Fort Yuma. Send down some belts for the repair of White’s mill at the Pima Villages. Please order Captain McAllister to send down by return boat a good supply of percussion caps. I am afraid to depend on the tape-primers altogether. Majors Woods and Drum left for Fort Yuma April 9,1862. Lieutenant-Colonel West with five companies is now passing the Yuma desert. (See my instructions to that officer which went up by the last boat). Colonel Bowie doubtless reaches Camp Wright to-day. Two companies more leave that camp for Fort Yuma as soon as practicable after Colonel Bowie’s arrival, and two companies of cavalry and Shinn’s battery will leave Camp Drum for Temecula en route to Fort Yuma this week. This leaves at Camp Drum Major Fergusson and one company of cavalry to escort the funds, which I confidently look for on the return boat. Unless the teamsters are paid a part of their wages at least they will quit. I must have money. I can revolutionize Sonora with coin as against the secession scrip, even admitting Sibley to have the country, which he is not understood to have. If you could send down the Indian goods named in my list of December I could buy all of White’s wheat back, which the secessionists seem to have distributed among the Indians. Send all funds, whether subsistence or quartermaster’s, to Lieutenant Hammond, who will wait at Camp Drum with Major Fergusson to receive them. Please leave none of this business undone for still another boat. The weather is getting hot, and time now is of immense value. Send 100 tons of barley to San Pedro, and say 20,000 rations of subsistence, but no more until estimated for. I am, captain,

very respectfully, your obedient servant,
