Unknown to E. A. Rigg, April 10, 1862

Maj. E. A. RIGG, i Commanding at Fort Yuma, Cal.: MAJOR: I have just ordered Major Coult with Roberts’ and Ford’s companies of infantry, with two mountain howitzers and with two wagon loads of hospital stores, to proceed from Camp Wright without

a delay and report to you at Fort Yuma. The transportation which accompanies this command will doubtless be fourteen wagons, which you will doubtless need at the fort or in advance of the fort. Otherwise return such as are not needed to Camp Wright. I have ordered a new hospital tent, poles, &c., to be sent. These will be forwarded to Lieutenant-Colonel West by the first opportunity. Major Woods, with funds to pay your troops, and Major Drum, to inspect your post and command, left here to-day for Fort Yuma. Yourself and West are too good soldiers not to have spies watching and reporting upon every movement of an enemy, let him be where he may, within 200 miles of you. I am very anxious to hear the result of Calloway’s and Pishon’s enterprise. I am very anxious to hear that the brig Rice has arrived. There is no doubt but Major Drum will find your post in the finest possible order, and everything about it neat and clean, and all your defenses in first-rate order.

Respectfully, your obedient servant,
