The Western Metropolis was a notable wooden side-wheel steamship constructed in 1863 at the Atlantic Marine Railway Company shipyard in Red Hook, Brooklyn. Measuring 290 feet in length with a beam of 40 feet and a depth of hold of 23 feet, she displaced approximately 2,250 tons. Her hull was entirely built of oak, reflecting the robust construction typical of the era. Propelled by side-mounted paddlewheels powered by a walking beam steam engine—originally used in ships on the Great Lakes—her engine featured a 76-inch diameter cylinder and a 12-foot stroke, and was installed in her by the time of her launch. Initially built to support Union military logistics during the American Civil War, Western Metropolis was chartered by the Union Army’s quartermaster corps in December 1863. She was unarmed but demonstrated resourcefulness by capturing a Confederate blockade runner, Rosita, in January 1864 near Key West. Throughout her wartime service, she transported troops, horses, and wounded soldiers, notably serving as a hospital ship equipped with lifts for non-ambulatory patients and staffed by doctors and nurses, carrying thousands of wounded from battles such as those at Newport and Alexandria. Her service also included participation in the first assault on Fort Fisher, where she transported Union troops. Post-war, she undertook trans-Atlantic voyages, making five crossings and bringing thousands of Northern European immigrants to the United States. She also engaged in commercial trade, carrying cotton, grain, and manufactured goods between New York, New Orleans, and Europe. In 1866, she underwent refits, including the installation of feathering paddlewheels designed to improve fuel efficiency, but these proved costly and problematic, with many paddle blades breaking during trials. She was subsequently sold to the North American Lloyd Line, operated by the Ruger Brothers, who attempted trans-Atlantic service with her. However, her paddlewheels continued to cause issues, leading to several repairs and a series of short-lived voyages. Later, she entered service with the Merchants' Line, primarily transporting cargo and passengers between New York and New Orleans until 1875. Her career was marred by mechanical failures, including a cracked shaft in 1871 and repeated engine troubles. Her engine was eventually removed in 1878 when she was sold to Charles Delameter of the Delameter Iron Works, after which her ultimate fate remains unknown. Western Metropolis's long and varied career exemplifies the transitional period of maritime technology during and after the Civil War, highlighting both her logistical importance and the challenges of aging maritime technology.
