ORP Piorun (G65)

ORP Piorun was an N-class destroyer used by the Polish Navy during the Second World War. The name is Polish for "Lightning".

History
The ship was built by John Brown & Company of Clydebank, Glasgow. She was laid down in July 1939, launched on 7 May 1940 and completed on 4 November 1940. Initially commissioned into the Royal Navy as HMS Nerissa, she was later transferred to the Polish Navy as a replacement for the destroyer ORP Grom, which had been lost off the Norwegian coast on 4 May 1940.

Piorun was based in Great Britain and commanded by Commander Eugeniusz Pławski. Between 13 and 15 March 1941, while undergoing repairs in John Brown's shipyard, she took part in the defence of Clydebank against air raids by the Luftwaffe. A memorial to the crew of the ship was later erected in Clydebank.

Bismarck action
On 22 May 1941, Piorun, with ships of the British 4th Destroyer Flotilla (HMS Cossack, HMS Maori, HMS Sikh and HMS Zulu), commanded by Captain Philip Vian, provided additional escort to troop convoy WS8B en route from Glasgow to the Indian Ocean. On 25 May, Vian's destroyers (including Piorun) were detached from the convoy to join the search for the German battleship Bismarck.

Piorun took part, along with the British destroyers, in the search for the Bismarck (she was the first of the destroyers to spot the German ship). She joined in the shadowing of and torpedo attacks on the Bismarck during the night before Bismarck was sunk, and at one point Piorun charged at Bismarck by herself, exchanging fire for half an hour, although neither side scored any hits. According to one report (detailed at the Auschwitz I exhibition, Oświęcim, Poland), Pławski transmitted the message "I am a Pole" before commencing fire on the Bismarck. This manoeuvre and the subsequent withdrawal caused Piorun to lose contact with the Bismarck. Piorun was very low on fuel, so at 5 am, she was ordered home before she had used her torpedoes. Pławski was reluctant to leave the area and ignored Vian's order for an hour before returning to the UK.

Subsequent activity
She subsequently operated in the Mediterranean, taking part in Operation Halberd, one of the Malta convoys and Operation Husky, the invasion of Sicily. In 1944 she was transferred to the Home Fleet.

Piorun took part in Operation Deadlight, and took part in the sinking of the captured German Type XXI submarines U-2329, U-2334, U-2335, U-2337, U-2350 and U-2363.

She was returned to the Royal Navy in 1946, as HMS Noble and scrapped in 1955.
