James H. Carleton to W. Scott Ketchum, October 15, 1861

Maj. W. Scott KETCHUM, Commanding at San Bernardino :

MAJOR: Agreeably to instructions received from Colonel Wright, U. S. Army, I have ordered Maj. Edward E. Eyre, First Cavalry California Volunteers, with three companies of that regiment to San Bernardino to relieve the force under your command so as to enable you to march [to] San Pedro. Please do me the favor to give to Major Eyre the many useful hints as to the management of affairs in the vicinity of Bernardino which your experience there may suggest. I count confidently on your kindness in this regard. The major will have to hire a private physician. Pray inform him who the best man is that can be employed. Judge Winston’s train, which goes out with Major Eyre, you can have to transport the baggage of your troops to San Pedro. J shall send an ambulance to San Bernardino with some of the sick of the cavalry. This ambulance can be used as transportation for Dr. Randle, ordered to join Colonel West at Chino Ranch.

Respectfully, your obedient servant,
