HMS Unison
HMS "Unison" (P43) was a Royal Navy U-class submarine built by Vickers-Armstrong at Barrow-in-Furness, and part of the third group of that class. She is the only craft of the Royal Navy to have borne the name "Unison". Prior to receiving the name, she carried the pennant number "P43" and was unofficially known as "Ulysses." Career. "Unison" spent most of her wartime career in the Mediterranean, where she sank the Italian merchants "Enrichetta", "Marco Foscarini" and "Terni", the Italian sailing vessels "Luigi Verni", "Carlo P." and "Angela", the German coaster "Jaedjoer" and the Italian  tanker "Zeila". She also damaged the Italian tanker "Pozarica", and unsuccessfully torpedoed the Italian merchant "Chisone" and a medium-sized tanker identified as the Italian auxiliary "Cerere". She took part in operation Harpoon, when she torpedoed an Italian cruiser force composed of the light cruisers and without hitting any target on 13 June 1942. On 2 August 1943 "Unison" was fired on in error by the American tanker "Yankee Arrow" off Cape Bon, causing damage to her pressure hull, although she was able to return to dock at Bizerte under her own power. The attack killed the officer of the  watch, and severely injured three other crew members, including her captain, Lieutenant Anthony Daniell DSO DSC. She was transferred to the Soviet Navy on 26 June 1944, and renamed "V3". She spent five years in Soviet service, being returned in 1949 and scrapped at Stockton in May 1950. During War Week, March 1942, HMS "Unison" was adopted by the people of Ashby-de-la-Zouch. Both the rural district council and the urban district council of Ashby were later presented with plaques commemorating their support for the vessel and her crew. These plaques were recently discovered, reunited and presented to  Ashby de la Zouch museum to be put on display.
