Benicia Arsenal

The Benicia Arsenal and Benicia Barracks were part of a large military reservation located next to Suisun Bay in Benicia, California. For over 100 years, the arsenal was the primary US Army Ordnance facility for the West Coast of the United States.

In 1847 a 252-acre parcel of land adjoining the Benicia city limits on the east was acquired for a military reserve. First occupation of the post was on April 9, 1849, when two companies of the 2nd Infantry Regiment set up camp to establish Benicia Barracks, which also housed the 3rd Artillery Regiment. In 1851, after the urging of General Persifor F. Smith, the first Ordnance Supply Depot in the West was established in Benicia. In 1852 it was designated Benicia Arsenal. Notable military personnel who were stationed there during this time include Ulysses Grant, Edward Ord, and Joseph Hooker, among others.
