SIR: I have received a telegraphic dispatch Nicodemus, to the effect that Colonel Carleton, with 500 California Volunteers, was on this side of the Pima Villages on the 7th of May, moving in the direction of the Mesilla Valley, I wish you to advance a portion of your command,say 1,000 men, if you have the means of moving and supplying that number, in the direction of Santa Barbara, open a communication with Colonel Carleton, if possible, and hold yourself in readiness to support him if he should be advancing on this side of Tucson. Unless it should be absolutely necessary, in order to support Colonel Carleton, I do not with the command moved into the Mesilla Valley until I have the means of subsisting them there.
