HMS Grenadier (T334): The Trawler That Pulled Thirty Men From the Atlantic

Built From a Fishing Boat Design

HMS Grenadier was built by Cook, Welton & Gemmill at Beverley, ordered on 7 February 1942, laid down on 13 June 1942 and launched on 26 September that year, a 750-ton Military-class anti-submarine trawler based on prewar fishing vessel designs, the kind of quick, practical adaptation the Royal Navy relied on heavily to fill the desperate wartime shortage of escort vessels.

Powered by a steam reciprocating engine developing 1,000 indicated horsepower for a modest top speed of 11 knots, she carried a single four-inch gun on her forecastle, six 20mm anti-aircraft guns, two heavy machine guns and depth charge throwers and racks, a crew of 40 officers and men working a properly no-frills little warship.

She entered service on 10 February 1943 under the command of Acting Skipper Lieutenant Arthur George Day, RNR.

Convoy Escort and Anti-Submarine Patrols

HMS Grenadier spent 1943 working up with anti-submarine exercises at Tobermory that March alongside HMS Mutine, HMS Rhododendron and the Dutch submarine HrMs O 10, and off Lough Foyle that October with HMS H 33, two of the Royal Navy's principal training grounds for exactly this kind of escort work, before taking on genuine operational convoy duty that June and July, escorting convoy MKS 16 from Gibraltar as part of the wider combined SL 132/MKS 16 convoy operation, arriving Liverpool on 22 July.

Through March 1944 she conducted a further round of anti-submarine exercises off Stornoway alongside HMS United and HMS Lancer, the steady, repetitive training and patrol work that made up the bulk of a wartime trawler's life, rarely making headlines but essential to keeping the sea lanes safe.

A Rescue in the War's Final Weeks

HMS Grenadier's most dramatic moment came on 16 March 1945, with the war in Europe entering its final weeks, when she rescued 30 survivors some three nautical miles off Neist Point on the Isle of Skye from the merchant vessel Inger Toft after she was torpedoed by the German submarine U-722, a notably welcome piece of good news amid the last, still dangerous phase of the Battle of the Atlantic, when U-boats remained capable of inflicting real losses right up to the German surrender. U-722 herself did not get to enjoy her success for long, sunk just eleven days later, on 27 March, by depth charges from the frigates HMS Fitzroy, HMS Redmill and HMS Byron, a piece of rough justice Grenadier's rescued survivors would surely have appreciated.

A Postwar Career at Sea

HMS Grenadier concluded her active naval service in late 1945 and was sold to mercantile owners on 10 April 1946, continuing to work at sea under civilian ownership as the renamed trawler Thuringia (GY 321) for another two decades, before finally being scrapped at Dunston-on-Tyne on 30 October 1966, closing out the career of a small, purpose-built wartime trawler that had spent her active years doing the patient, unglamorous work of convoy escort, and, when it mattered most, pulling drowning sailors out of the Atlantic.
