return to Contents List    


Canadian Pacific Passenger Liner requisitioned on 28th August 1939 and hired for use as an Armed Merchant Cruiser. The ship was to have been named METAPEDIA but was later renamed MONTCLARE. She was ordered from John Brown at Clydebank and launched on 18th December 1921. Her machinery was provided by Harland and Wolff and on completion she was deployed for cross-Atlantic passenger trade. Details of her tonnage and machinery as well as her armament during naval service are given in the General Description information for Armed Merchant Cruisers, This ship was converted for deployment as an Armed Merchant Cruiser and retained her mercantile name which had not previously been borne by an RN ship. She carried out trade protection duties until 1943 when she was purchased outright by the Admiralty and selected for further use as a Depot Ship for destroyers. The ship then underwent an extensive conversion for her new role and was allocated for service in the Pacific.. On return to UK after the end of hostilities she was again converted to suit the support of submarines and served in the Clyde until 1955 when she was placed in Reserve until being sold in 1957 for demolition.
