HMS Polyanthus was a Flower-class corvette of the Royal Navy. She was launched on 30 November 1940 from Leith Docks on the Firth of Forth, at an estimated cost of £55,000.[1][2] Polyanthus was sunk by the German submarine U-952 using new German weapons technology on 20 September 1943 about 1,000 miles southwest of Reykjavík during convoy escort duty in the Battle of the North Atlantic.[3][4][5]
Background
[edit]Flower-class corvettes like Polyanthus serving with the Royal Navy during World War II were different from earlier and more traditional sail-driven corvettes.[6][7][8] The "corvette" designation was created by the French in the 19th century as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.[9] During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design.[10] The generic name "flower" was used to designate the class of these ships, which – in the Royal Navy – were named after flowering plants.[1]
War duty and sinking
[edit]Although designed for quick and cheap construction, Polyanthus and ships like her in the Flower class were operative in convoy escort during the Battle of the North Atlantic.[11] The primary mission of protection against U-boats saw Polyanthus active in several transatlantic convoys in the early part of the war. By late 1943, the Kriegsmarine were using an acoustic homing torpedo - known to the Allies as a GNAT - which they hoped would reverse the changing tide of war, favouring the Allies in the Atlantic.[12]
On the night of 19–20 September 1943, two westbound Convoys ONS18 and ON 202 were facing frequent U-boat engagements, calling Polyanthus to their aid in the wake of several setbacks, including the near destruction of HMS Escapade and HMS Lagan.[12] After successfully driving away U-238, Polyanthus was ordered to rescue the crew from the escort HMCS St. Croix, recently sunk by U-305. Whilst under the command of Lieutenant John Gordon Aitken RNR, Polyanthus was sunk by U-952 using a GNAT before any rescue could be effected.[3][13] At least 7 officers and 77 crew were lost with Polyanthus among them Lt Graham Shepard. The only known survivor drowned within days at the hands of another U-boat attack on the ship that rescued him, HMS Itchen.[3]
