HMS M27 was a First World War Royal Navy M15-class monitor. She was also served in the British intervention in Russia in 1919, and was scuttled in the Dvina River on 16 September 1919.
Intended as a shore bombardment vessel, M27's primary armament was a single 9.2 inch Mk VI gun removed from the Edgar-class cruiser HMS Theseus. [1] In addition to her 9.2 inch gun she also possessed one 12 pounder and one six pound anti-aircraft gun. She was equipped with a four shaft Bolinder two cylinder semi-diesel engine with 560 horse power that allowed a top speed of eleven knots. [2] The monitor's crew consisted of sixty nine officers and men.
HMS M27 ordered in March, 1915, as part of the War Emergency Programme of ship construction. She was laid down at the Sir Raylton Dixon & Co. Ltd shipyard in March 1915, launched on 8 September 1915, and completed in November 1915.
M27 served with the Dover Patrol from December 1915 to December 1918. In early 1916, M27 had her main 9.2in gun removed, as it was required for artillery use on the Western Front, and a QF 6-inch (150 mm) MK I/II gun from HMS Redoubtable was fitted in lieu. This was later replaced by a 6-inch (152.4 mm) MK VII gun.
M27 next saw service, along with five other monitors (M23, M25, M31, M33 and HMS Humber), which were sent to Murmansk in May 1919 to relieve the North Russian Expeditionary Force. Prior to departure to Russia, M27 had her main armament replaced by a BL 4-inch (101.6 mm) triple Mk IX gun, and her 12pdr (76mm) QF Mk 1 gun replaced by a QF 3-inch (76 mm) AA gun.
In June, 1919, M27 moved to Archangel and her shallow draught enabled her to travel up the Dvina River to cover the withdrawal of British and White Russian forces. M27 and her sister ship M25 were unable to be recovered when the river level fell and were scuttled on 16 September 1919 after running aground.
The M29 class comprised five monitors of the Royal Navy, all built and launched during 1915.
HMSM33 is an M29-class monitor of the Royal Navy built in 1915. She saw active service in the Mediterranean during the First World War and in Russia during the Allied Intervention in 1919. She was used subsequently as a mine-laying training ship, fuelling hulk, boom defence workshop and floating office, being renamed HMS Minerva and Hulk C23 during her long life. She passed to Hampshire County Council in the 1980s and was then handed over to the National Museum of the Royal Navy in 2014. A programme of conservation was undertaken to enable her to be opened to the public. HMS M33 is located within Portsmouth Historic Dockyard and opened to visitors on 7 August 2015 following a service of dedication. She is one of only three surviving Royal Navy warships of the First World War and the only surviving Allied ship from the Gallipoli Campaign, the other being the Ottoman minelayer Nusret, preserved in Çanakkale.
HMS Cordelia was a C-class light cruiser built for the Royal Navy during World War I. She was one of six ships of the Caroline sub-class and was completed at the beginning of 1915. The ship was assigned to the 1st and 4th Light Cruiser Squadrons (LCS) of the Grand Fleet for the entire war and played a minor role in the Battle of Jutland in mid-1916. Cordelia spent most of her time on uneventful patrols of the North Sea. She served as a training ship for most of 1919 before she was recommissioned for service with the Atlantic Fleet in 1920. The ship was placed in reserve at the end of 1922 and was sold for scrap in mid-1923.
