During World War II, the Basalt Rock Company located south of the City of Napa on the Napa River, built 3 dozen salvage rescue tugs for the United States Navy. German prisoners of war were housed in a Camp Beale satellite prisoner of war camp near Yountville. The prisoners were utilized to supplement a dwindled able bodied agricultural labor force caused by the needs of the American war effort.
