This battalion was organized at Franklin, Texas, under the command of Major Joseph Smith, between November and December, 1864, by consolidating the veterans of the 1st Regiment California Volunteer Infantry, into two companies, which became Companies A and B, and consolidating the companies of the 5th Regiment California Volunteer Infantry into five companies, which became Companies C, D, E, F, and G, of the battalion. On March 16, 1865, a Company F was broken up for the purpose of distributing the men among the other companies, due to the difficulty in obtaining recruits to keep up all the companies to the minimum required by law. The same order directed Colonel Rigg to assume command with the rank of Lieutenant-Colonel, with headquarters at Fort Craig. The battalion was mustered out in September 1866. When this battalion was mustered out in September 1866, officers and members who wished to be mustered out in California were consolidated into a company, under Captain William F. French, First Lieutenant Robert Edmiston, and Second Lieutenant William Oman and marched to the Presidio, San Francisco, where they arrived December 28, and were mustered out on December 31, 1866. The men of this company mustered out at the Presidio were accounted for in the individual record as having been "discharged at San Francisco, December 31, 1866, by final muster out of the regiment."
Company D: Mustered out at Los Pinos, N. M., September 15, 1866.
Company E: Mustered out at Los Pinos, N. M., September 15, 1866.
Company F: Formed at Las Cruces, New Mexico, November 30, 1864. Disbanded at Fort Cummings, March 16, 1865. Soldiers distributed to other companies.
Company G: Mustered out at Los Pinos, N. M., September 15, 1866.
* January 1866. While six men of the company were performing daily duty—cutting wood for this garrison at Oak Grove, about five miles distant, on the seventeenth instant—they were surprised and fired upon by Apache Indians. The number of Indians was estimated at about forty or more. Four men were killed, and two escaped — Privates John H. Matthews and Nathaniel B. Goldsberry, the latter with an arrow wound in his hip. Private Matthews displayed exemplary courage in defending himself, as well as virtually saving the life of Goldsberry, who was scarcely able to render any defense. One Indian was killed and indications showed others wounded.
