SM U-90 was a Type U 87 u-boat of the Imperial German Navy during World War I.[4]
The commander, Walter Remy, was noted for making regular stops at the very remote UK island of North Rona for provisions, including fresh mutton. On 15 May 1918 the submarine shelled the British Royal Navy wireless station on Hirta in St Kilda, Scotland.
On 31 May 1918, U-90 torpedoed and sank USS President Lincoln. The ship was a former Hamburg America Line steamer of the same name seized by the United States and employed as a troop transport. From the U.S. Navy crew that abandoned the sinking vessel, U-90 captured Lieutenant Edouard Izac, eventually taking him to Germany. Izac would later escape German captivity and report to the US Navy about German submarine movements.
