The seaport and the shipyard both witnessed several air raids by the Allies from 1943 onwards, but suffered little damage. Gotenhafen was used during winter 1944–45 to evacuate German troops and refugees trapped by the Red Army. Some of the ships were hit by torpedoes from Soviet submarines in the Baltic Sea on the route west. The ship sank, taking about 9,400 people with her – the worst loss of life in a single sinking in maritime history. The seaport area was largely destroyed by withdrawing German troops and millions of encircled refugees in 1945 being bombarded by the Soviet military (90% of the buildings and equipment were destroyed) and the harbour entrance was blocked by the German battleship that had been brought to Gotenhafen for major repairs.
