James H. Carleton to E. A. Rigg, February 20, 1862
Maj. E. A. RIGG, First Infantry California Volunteers, Comdg. at Fort Yuma: MAJOR: The paymaster will be at your post with funds to pay the troops in the month of March. I am anxious to know the exact condition of your defenses; whether the 12-pounders have been received and are in position and whether you have ammunition for them before that is received which goes by Veck’s train. That you keep yourself in a state of preparation for immediate action and have spies and scouts to give you timely notice of the approach of an enemy, I can have no doubt. Much is expected from yourself and your command. The eyes of California are resting upon you. If you are attacked, a successful defense will give you all immense credit not only here but throughout the country. The Mojave expedition will not be delayed on account of the rebel forces reported as being in Arizona. Troops will move from here across the desert direct upon that route as soon as transportation can be gotten. Have all your packs in readiness, so that when your mules come you can move up the Colorado with a part of your present garrison if necessary. Can you get any Indian guides from your post to the Mojave Villages? I am, major,
very respectfully, your obedient servant,
Colonel First California Infantry, Commanding.
