HMS Calypso (D61)

Calypso fought in the Second Battle of Heligoland Bight on 17 November 1917, when she and her sister ship Caledon were part of the force that intercepted Kaiserliche Marine (Imperial German Navy) minesweepers near the German coast. During the battle, Calypso's bridge was struck by a 5.9 in (150 mm) shell which killed everyone on the bridge including the captain and caused the accidental firing of a ready torpedo.^[4][5]

Calypso went to the rescue of the Greek royal family in 1922 after King Constantine of Greece abdicated and a military dictatorship seized power. The King's brother, Prince Andrew of Greece and Denmark was banished for life by a revolutionary court and was forced to flee with his family, which included his 18-month-old son Philip who would later become Prince Philip, Duke of Edinburgh.^[6] The British Government had received news of the situation, and dispatched Calypso to evacuate the family. They boarded with minimal possessions. Philip was carried on board in a cot made from an orange box. The family were taken to Brindisi, Italy, where they were put on a train to Paris.

On 2 November 1924, the destroyer HMS Venomous was steaming in the Grand Harbour upon returning to Valletta, Malta, from a cruise in the Western Mediterranean Sea when she accidentally rammed and sank a motorboat from Calypso. All four people aboard the motorboat were saved by a boat from the destroyer HMS Umpire.^[7][8]

During the early part of the Second World War, Calypso served with the 7th Cruiser Squadron on Northern Patrol duty as a blockade ship in the North Sea between Scotland and Iceland. On 24 September 1939, Calypso intercepted the German merchant ship Minden south of Iceland. The crew of Minden scuttled their ship before she could be captured. On 22 November, Calypso captured the German merchant ship Konsul Hendrik Fisser off Iceland. Following the sinking of the Rawalpindi on 23 November, Calypso was involved in the search for the German warships Scharnhorst and Gneisenau. In early 1940, Calypso was sent to Alexandria in the eastern Mediterranean.

Calypso was the first British naval vessel to be sunk by the Regia Marina in the Second World War. Two days after Italy declared war on Great Britain, Calypso was on an anti-shipping patrol against Italian ships travelling to Libya when she was struck by a torpedo from the Italian submarine Alpino Bagnolini (Capitano di corvetta (Lieutenant Commander) Franco Tosoni Pittoni [it]) about 50 mi (80 km) south of Cape Lithion in Crete in the Eastern Mediterranean at 00:59 on 12 June 1940. Thirty nine sailors from Calypso perished in the sinking.^[9] The majority of her survivors were rescued by the destroyer Dainty and taken to Alexandria.
