This regiment was organized at Stockton and at Benicia Barracks, from October 31 to December 31, 1861, to serve three years. The regiment was first commanded by Colonel Patrick Edward Connor. After the formation of the regiment at Stockton, four companies were sent to Humboldt County during the month of November, 1861.

It spent its entire term of service in the western United States. Its largest engagement was the Bear River Massacre or Battle of Bear River on January 29, 1863 in southeastern Washington Territory (present-day Franklin County, Idaho).

On the expiration of its term of service, the original members of the regiment (except veterans) were mustered out, and the veterans and new recruits were consolidated into a battalion of four companies on October 29, 1864, and was afterwards known as the Third Battalion of Infantry, comprising companies, A, B, C, and D. On December 9, 1865, Companies C and D were consolidated, leaving only three companies in the battalion. The battalion was finally mustered out July 27, 1866.
