HMS Royal Oak

HMS Royal Oak was a Revenge class battleship, most famous for her destruction by U-47 while at anchor in Scapa Flow in 1939. She had been laid down in January 1914, and entered service in May 1916, making her one of the newest ships to take part in the battle of Jutland. There she formed part of the main Grand Fleet, taking part in the two brief battleship clashes.

Although the Revenge class ships were retained after the First World War, they were not as highly regarded as the Queen Elizabeth class ships, and so did not benefit from extensive modifications. The Royal Oakwas modified in 1922-24, when she was given anti-torpedo bulges. In 1934-36 her deck armour was improved.

At the start of the Second World War, the Royal Oak was part of the Home Fleet, based at Scapa Flow. On the night of 14 October 1939, U-47 commanded by Gunther Prien, managed to get past the anti-submarine defences of Scapa Flow. He fired two salvoes of torpedoes at the Royal Oak. Only one torpedo from the first salvo hit, causing a small explosion. Onboard the Royal Oakthis was believed to have been an internal explosion, and the flammable stores were flooded. However, three or four torpedoes from the second salvo hit, ripping the bottom out of the ship. She sank in ten minutes, with the loss of over 800 lives. Amongst them was Rear-Admiral H. E. C. Blagrove. Prien returned to a hero's welcome in Germany, which included a triumphal procession through Berlin. Just as in 1914, the British fleet was forced to abandon Scapa Flow while its defences were improved.
