James H. Carleton to E. A. Rigg, April 22, 1862

Maj. E. A. RIGG, First Infantry California Vols., Comdg. Fort Yuma, Cal.: MAJOR: Since writing to you yesterday circumstances have rendered – it necessary to delay Winston’s train in reaching Yuma some two or three days, so you can have Shirland and McDonald’s train await above Fort Yuma, where there is good grass or hay abundant, and rest until further orders. Send Cremony to the same point on his arrival to await Winston’s train. I shall perhaps be at Fort Yuma as soon as Cremony. I wish you to send two loads of hay out upon the desert to the points where it is most needed, to be kept exclusively for the use of Shinn’s light battery as it comes on. He will have 125 horses and mules. I am, major,

very respectfully,
