SMS Cormoran (II) was a German armed merchant raider active during World War I, originally built as the Russian merchant vessel Ryazan in 1909 at the Schichau shipyard in Elbing, Germany. Designed for North Pacific routes, the vessel served as a passenger, cargo, and mail carrier before her capture. On August 4, 1914, the German light cruiser SMS Emden seized Ryazan southeast of Korea, and she was taken to Kiautschou, a German colony, for conversion into a raider. Her conversion involved transferring her armaments from the older SMS Cormoran, a shallow-draft cruiser that had previously operated in the Pacific. Rechristened SMS Cormoran II, the vessel departed Qingdao on August 10, 1914, and patrolled the South Pacific, engaging in commerce raiding. Her operations were curtailed when Japan entered the war, forcing her to seek refuge at Apra Harbor, Guam, on December 14, 1914. Stranded with limited coal and lacking sufficient provisions, the ship's crew burned much of her woodwork to sustain her boilers, and the US authorities, under diplomatic strain, refused to supply additional coal beyond a token amount. This led to a prolonged standoff lasting nearly two years, during which the crew were treated as guests and gained local notoriety. Following the US declaration of war on Germany on April 6, 1917, the US Navy moved to seize the vessel. On April 7, 1917, as American authorities attempted to take control, the crew of Cormoran scuttled her by detonating an explosive device hidden in the coal bunker. The explosion caused debris to scatter across Apra Harbor, and most of her roughly 370 crew were rescued, with seven dying in the incident. The event marked the first violent action of the US in WWI, with the first shots fired by US forces against Germany. The wreck of SMS Cormoran rests 110 feet below the surface near Guam, leaning against the Japanese cargo ship Tokai Maru. The site has historical significance, being listed on the National Register of Historic Places, and is a popular diving location. The ship's bell is preserved at the US Naval Academy Museum, and the site continues to serve as a memorial and a reminder of early US involvement in WWI maritime history.
