Cornwall, formerly known as Cornwall Station, was an unincorporated community in Contra Costa County, California, before it was absorbed into the City of Pittsburg. It was located 7.25 miles (11.67 km) east-southeast of Baypoint and 1 mile (1.6 km) south of downtown Pittsburg, at an elevation of 39 feet (12 m) ASL.The area appears to have been named after Pierre Barlow Cornwall, an early California pioneer and president of the Black Diamond Coal Mining Company at nearby Nortonville, California from 1872 to 1904. Cornwall sprung up at the intersection of two railroads, the Black Diamond Coal Mining Railroad and the San Pablo and Tulare Railroad (the latter became part of the Southern Pacific system in 1888). The coal railroad crossed the San Pablo and Tulare line using an overhead trestle.A post office operated at Cornwall Station from 1881 to 1888. Cornwall post office operated from 1890 to 1911.The Cornwall area, together with the nearby town of Black Diamond, was officially renamed "Pittsburg" on February 11, 1911, which may explain why the Cornwall Post Office stopped operations in that same year.

Camp Stoneman was a United States Army facility located in Pittsburg, California. It served as a major troop staging area for and under the command of the San Francisco Port of Embarkation (SFPOE). The camp operated during World War II and the Korean War. The camp opened May 28, 1942 as a staging point for units deploying to the Pacific Ocean theater of World War II. The camp was named after George Stoneman, a cavalry commander during the American Civil War and Governor of California. It was decommissioned as a military post in 1954. The camp had a railroad track across the north side for receiving and shipping men. Late in the war the SFPOE experimented with embarking troops directly aboard a Liberty ship at the camp but that was not successful due to difficulties of large ship navigation to the camp. Next to the track, there were many buildings with loading docks, many of which were still there in 2017 along Bliss Avenue. There were seven barracks areas, each consisting of nine blocks (3 x 3) surrounding a mess hall. In addition to being a staging area for troops in transit, the Pacific Coast Transportation Corps Officer Training School was located at the camp. The camp also housed prisoners of war with the Italian Service Unit of the 18th Italian Quartermaster Service Company, which was based at the camp.
