Transferred to the RCN: 08 Jun 1944

Fate: Sold to Uruguayan navy in 1946. Paid off in 1975. Final disposition unknown.


Laid down as HMS Rising Castle K398, she was built by Harland & Wolff Ltd., Belfast, Ireland. After completion, in the midst of a dockyard strike, she was transferred and commissioned into the RCN on 08 Jun 1944 as HMCS ARNPRIOR K494 (renamed on the day she was commissioned). After working up at Tobermory she joined EG C-1 at Londonderry in August, leaving on 19 Aug 1944 to join her first convoy, ONM.249. ARNPRIOR was continuously employed as an ocean escort for the balance of the war. At the beginning of Jun 1945, she left Greenock for St. John's, where she underwent a two-month refit, and from September was based at Halifax. She was paid off there on 14 Mar 1946, and sold later that year to the Uruguayan Navy, which renamed her Montevideo and operated her as a training ship until 1975. (Mcpherson / Burgess - Ship's of Canada's Naval Forces 1910-1981)

The following paragraph from a letter written by A/LCdr, Stuart Thom, dated 29/5/45 held in the National Library and Archives Canada, gives an account of the Arnprior's convoy duty:  "It was not our good fortune to participate in any spectacular engagements with the enemy, but during the course of our 14 North Atlantic convoys, not one ship was lost. On no occasion ... did we miss a sailing date because of some defect and we never failed to finish a voyage on schedule". (Researched by / Courtesy of Gary King)
