SMS Greif was a German cargo steamship constructed with a steel hull, originally named Guben, and owned by the German-Australian Line (DADG) in Hamburg. She had a gross register tonnage (GRT) of approximately 4,962, reflecting her size and cargo capacity. In 1915, during World War I, she was converted from a merchant vessel into a merchant raider at the Kaiserliche Werft Kiel, a major German naval shipyard, and commissioned into the Imperial German Navy as SMS Greif on 23 January 1916. The vessel's service history is marked by her engagement in wartime raiding activities. Under the command of Fregattenkapitän Rudolf Tietze, Greif departed from the Elbe port of Cuxhaven on 27 February 1916. Her mission was cut short when, on 29 February 1916, she was intercepted in the North Sea by the Royal Navy’s armed merchant cruiser Alcantara. To conceal her identity, Greif was disguised as the neutral Norwegian vessel Rena, heading for Tønsberg, Norway. Despite this, she was detected and engaged. The confrontation was fierce; Greif hoisted the German battle ensign and opened fire on Alcantara, which responded with six 6-inch guns and two 3-pounders. During the battle, Alcantara was struck amidships by a torpedo from Greif, and a shell exploded her ready ammunition, causing further damage. Both ships slowed significantly, and after about 40 minutes of combat, Greif’s crew abandoned ship. Alcantara sank first, while Greif was later sunk by the British light cruiser Comus and destroyer Munster, who arrived to finish the engagement and rescue 120 German survivors. The battle resulted in the loss of approximately 187 Germans and 72 British sailors. The encounter underscores Greif’s role as a wartime commerce raider and highlights her brief but notable service in the German Imperial Navy’s efforts during World War I.
