Célpont: a Royal Oak

In the darkness of the night, on the 13th of October 1939, German submarine U-47 surfaced in Scapa Flow and crept slowly towards HMS Royal Oak. When the submarine was close enough, the commander of the U-boat, Günther Prien, had given orders to fire torpedoes. The battleship had no chance in this duel and very quickly started to sink. 833 men, including Rear-Admiral Henry Blagrove, died on board HMS Royal Oak.
