First Infantry California Vols., Comdg. at Fort Yuma, Cal. :

MAJOR: I have ordered Major Fergusson to send Pishon’s company

of the First Cavalry California Volunteers to report toyou. Twowagons lefthereto-day with plank for the repairs of Indian Well. These will proceed on directly to Fort Yuma to be used in trausporting supplies up to where McCleave and Cailoway and Pishon are to operate. Get the cavalry and mules up the river on grass without delay, so that not a straw of hay or kernel of corn more than absolutely necessary may be consumed this side of the Pima Villages. If McCleave is successful in the demonstration which he may make on Tucson, he can get a plenty of forage and beef there and from Sonora. To-morrow fifteen wagons laden with ammunition, provisions, &c., will leave San Pedro for Fort

Have every string drawn to the utmost and you will accomplish wonders. But again, keep your own counsels.

respectfully,
