Published: On 27 May 1941, HMS Dorsetshire sent the following signal to the commander-in-chief of the Home Fleet: “Torpedoed Bismarck both sides before she sank. She had ceased ring, but her colours were still flying.” Advertisement So ended the German battleship Bismarck’s only operational sortie, which had begun from the Polish coastal city of Gotenhafen (modern-day Gdynia) just over a week before. The dramatic story has been told and retold in books, documentaries, a feature film – and even a country and western song. But the truth remains, perhaps, the most compelling account of all. Bismarck was launched in February 1939. Weighing in at over 50,000 tons when fully loaded, she displaced more than any other European battleship in service; she was fast, well-protected and heavily armed. When Burkard von Müllenheim-Rechberg joined Bismarck in June 1940 as fourth gunnery officer and personal adjutant officer to the ship’s captain, Ernest Lindemann, he was fully trusting of her capabilities. “I had supreme confidence in this ship,” he wrote in his memoirs. “How could it be otherwise?”
