The first military base established in Los Angeles County was a temporary base established in San Pedro in 1846 by U.S. Navy Commodore Robert F. Stockton, commanding the U.S. Frigate Congress. Stockton landed at San Pedro and put ashore U.S. Marines and naval personnel to capture San Pedro and then march on to capture the Pueblo Los Angeles. Later determining that San Pedro was not then the ideal base for a naval vessel, Stockton moved his base to San Diego.
