HMCS Huntsville (K499) Castle class Corvette. Built by Ailsa Shipbuilding Co. Ltd., Troon, Scotland, she was laid down and launched as HMS Woolvesey Castle K461. On completion she was transferred to the RCN and commissioned as HMCS Huntsville on 6 Jun 1944, on the Clyde. She worked up at Stornoway early in July and joined EG C-5 at Londonderry later that month, leaving on 11 Aug 1944 for ONS.248, her first convoy. In Nov 1944 Huntsville missed a convoy while under repair in Halifax and acted as local escort to one convoy from St. John’s to New York – seemingly the only ship of her class to visit there. Rejoining the Atlantic convoy cycle in Dec 1944, she left Londonderry for the last time on 16 Apr 1945, to meet ON.297. In May 1945 she commenced refit at Halifax, completed in Aug 1945, and in Sep 1945 she was placed in reserve. Paid off for disposal on 15 Feb 1946 at Halifax, and sold that year, she entered service in 1947 as SS Wellington Kent. Renamed Belle Isle II in 1951. Following a collision near Trois-Rivieres., Quebec, on 19 Aug 1960, she grounded and burned out.

HMCS Kincardine (K490) Castle class Corvette. Laid down and launched as HMS Tamworth Castle, she was, on completion, transferred to the RCN and commissioned at Middlesbrough on 19 June 1944 as HMCS Kincardine. After working up at Tobermory and Stornoway she arrived at Londonderry late in Aug 1944 to join EG C-2 but had to return to her builder’s for repairs. Returning to Londonderry in mid-Sep 1944, she remained on local duties until 02 Oct 1944, when she left to join ON.257, her first convoy. HMCS Kincardine served as an ocean escort for the remainder of the war, leaving ‘Derry for the last time at the beginning of Jun 1945. Briefly allocated to HMCS Cornwallis for training in Jul 1945, she then underwent a minor refit at Liverpool, Nova Scotia. She was placed in maintenance reserve at Halifax in Oct 1945, and then she was paid off there on 27 Feb 1946. Later that year she was sold to the French government and resold in 1947 to Moroccan interests, to be renamed Saada.

HMCS Leaside left St. John’s in Jun 1945 for Esquimalt, where she was paid off for disposal on 16 Nov 1945. Sold in 1946 to the Union Steamship Co., Vancouver, she was converted to a coastal passenger vessel and renamed Coquitlam. In 1950 she was renamed Glacier Queen. In 1970 she stripped in anticipation of becoming a floating restaurant but the plans for the restaurant fell through and she was left as a hulk. The hulk sank in Cook Inlet, Alaska, on 8 Nov 1978, but was raised and towed to sea and scuttled in Jan 1979.
