Ordered in March 1915,launched in May and commissioned in June must constitute something of a record for a warship but that was the beginning for the M29 Class Monitor HMS M33.She grossed 580 tons,a draught of 5'11",a top speed of 9.6knots and compliment of 72.Her armament was 2x6"guns,a 6pound Hotchkiss gun and 2xMaxim machine guns.Her first action was supporting the landings at Suvla Bay in the Gallipoli Campaign but it was during the Russian Revolution where she achieved fame.She sailed to Murmansk in 1919
to relieve the North Russian Expeditionary Force and then to Archangel to cover the withdrawal of the British/White Russian force and in sailing up the Dvina River her 2x6"guns had to be removed and transported by cart so shallow was the river.She decomissioned at Chatham later in
1919 and in 1925 was converted to a coastal minelayer and renamed HMS MINERVA.She can be seen today near to HMS Victory in Portsmouth Dockyard.
