Camp Reynolds, Angel Island State Park, Angel Island, Marin County, CA

Significance: Following the admission of California to the Union in 1850, all of the islands in San Francisco Bay, including Angel Island, were reserved for 'public purposes' by the U.S. government. The outbreak of the Civil War in 1861 gave new urgency to the defense of the bay. Although no military activity occurred on Angel Island until 1863. In August of that year the U.S. Army corps of engineers surveyed the island for artillery battery locations, and construction began shortly thereafter on the batteries and associated quarters. On 12 September, Company B of the 3rd artillery occupied the newly established Camp Reynolds on Angel Island.
