The regiment was organized at Stockton and Benicia Barracks from October 31 to December 31, 1861, to serve three years.

During July, 1862, Colonel Connor was sent, with his regiment, to the District of Utah, where it remained for the balance of its term of service.

The regiment's officers were presented with a silk national flag by H. B. Underbill inside the Agricultural Hall in Stockton on 23 February 1862.
