Cap Arcona, named after Cape Arkona on the island of Rügen, was a large German ocean liner built for the Hamburg Südamerikanische Dampfschifffahrts-Gesellschaft ("Hamburg-South America Line"). She carried passengers and cargo between Germany and the east coast of South America, and in her time was the largest and quickest ship on the route.In 1940 the Kriegsmarine requisitioned her as an accommodation ship. In 1942 she served as the set for the German propaganda feature film Titanic. In 1945 she evacuated almost 26,000 German soldiers and civilians from East Prussia before the advance of the Red Army. Cap Arcona's final use was as a prison ship. In May 1945 she was heavily laden with prisoners from Nazi concentration camps when the Royal Air Force sank her, killing about 5,000 people; with more than 2,000 further casualties in the sinkings of the accompanying vessels of the prison fleet; SS Deutschland and Thielbek. This was one of the biggest single-incident maritime losses of life in the Second World War.
