Black Diamond Steamship Company

Black Diamond Steamship Company (BDSC) operated passenger and cargo liners from New York City to Rotterdam and Antwerp. It was founded by J.E. Dockendorff in 1919, and named the American Diamond Line by the United States Shipping Board. The company was profitable in the 1920s and early 1930s. Prior to the United States' entry into World War II, the nation's neutrality policy ended much of the lines trade. Dockendorff stepped down as a principal executive in 1934, selling the only one of the company's 21 ships not owned by the government: New Britain, which he had bought in 1918. During World War II the company sold most of its American Diamond Line ships and moved to charter shipping with the Maritime Commission and War Shipping Administration. During the war, the Black Diamond Steamship Company operated Victory ships and Liberty ships. These ships were operated by their own crews; the US Navy supplied United States Navy Armed Guards to man the deck guns and radio. The most common armament mounted on these merchant ships were the MK II 20mm Oerlikon autocannon and the 3"/50, 4"/50, and 5"/38 deck guns. After the war there were many surplus ships and much competition. Black Diamond Steamship Company continued to operate after the war, but finally closed in 1955.



American Diamond Lines
American Diamond Line was started at the end of World War I in 1919, by the United States Shipping Board. American Diamond Lines became a subsidiary of Black Diamond Steamship Company in 1920, a profitable company in the 1920s and early 1930s that operated 20 ships. In 1929 the American Diamond Line was put up for sale. Two companies lobbied the US Shipping Board for American Diamond Lines: Black Diamond Shipping Corporation and the Cosmopolitan Shipping Company. The lobby and appeals were taken all the way to President Herbert Hoover. Then in 1931 the Shipping Board sided with Black Diamond Steamship Corporation, which purchased back American Diamond Lines. Due to the USA's neutrality in early war years, American Diamond Lines charted some of its ships to foreign-flag shipping companies in order to continue its European trade. American Diamond Lines was not able to get Government subsidies post World War II and declined, closing in 1955 as part of Black Diamond Steamship.
