The German auxiliary cruiser Widder (HSK 3), also known as Schiff 21 to the Kriegsmarine and Raider D to the Royal Navy, was originally built as a cargo ship named Neumark. Launched in 1929 at Howaldtswerke in Kiel, she was initially operated by the Hamburg America Line (HAPAG). In late 1939, the Kriegsmarine requisitioned her for conversion into a commerce raider, and she was extensively modified by Blohm+Voss before being commissioned as Widder on 9 December 1939. Widder’s notable service began with her sole raiding voyage in May 1940 under Korvettenkapitän Helmuth von Ruckteschell. She departed from Germany on 6 May 1940, heading to Bergen, Norway. During her voyage, she engaged in an hour-long surface gun battle with the British submarine HMS Clyde, which ended inconclusively. After sheltering in Sandsfjord, she resumed her mission, crossing the Arctic Circle on 15 May. On 21 August 1940, she sank the British steamer Anglo Saxon approximately 800 miles west of the Canary Islands, after which she refueled from the auxiliary ship Nordmark and navigated through the Denmark Strait. Over her five and a half months of operation, Widder captured and sank ten ships totaling 58,644 GRT. It is reported that she machine-gunned the crew of Anglo Saxon in their lifeboats, an act that led to war crimes charges against her captain. Following her raiding success, Widder returned to occupied France on 31 October 1940. However, due to persistent engine problems, she was deemed unsuitable for further commerce raiding and was reclassified as a repair ship, renamed Neumark. She played a significant role in repairing the battleship Tirpitz in 1943–44 while based in Norway. After the war, she entered British merchant service as Ulysses, was sold back to Germany as Fechenheim in 1951, and converted into a motor ship in 1954. Her maritime career ended when she was wrecked off Bergen in 1955 and subsequently scrapped. Widder was one of only two German auxiliary cruisers to survive the war after a single raiding voyage. Her captain, Helmuth von Ruckteschell, was among the few German naval commanders convicted of war crimes at war’s end. The vessel’s history reflects both her strategic role in wartime commerce interdiction and her complex post-war maritime legacy.
