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.

The Humber-class monitors were three large gunboats under construction for the Brazilian Navy in Britain in 1913. Designed for service on the Amazon River, the ships were of shallow draft and heavy armament and were ideally suited to inshore, riverine and coastal work but unsuitable for service at sea, where their weight and light draft reduced their speed from a projected twelve knots to under four. The class comprised Humber, Mersey and Severn. All three were taken over by the Royal Navy shortly before the outbreak of the First World War and were commissioned as small monitors. All three saw extensive service during the war and were sold in 1919.

HMS Taurus was an R-class destroyer which served with the Royal Navy during World War I. Ordered from Thornycroft in 1915 and launched in 1917, the vessel operated as part of the Harwich Force until the end of hostilities. Shortly after entering service, Taurus formed part of the destroyer shield for the Royal Navy's bombardment of Ostend that successfully sank the German destroyer S20. After the War, the destroyer was reduced to the Reserve Fleet and sold to be broken up in 1930.
HMS Satyr was an R-class destroyer which served with the Royal Navy during the First World War. Launched on 27 December 1916, Satyr joined the Harwich Force under the command of Commander Hubert de Burgh. In 1917, the destroyer formed part of a force protecting the monitors Erebus and Terror in their bombardment of Ostend. As part of this action, Satyr, along with sister ships Taurus, Sharpshooter and Torrent, sank the German destroyer S20. After the war, the ship served with the Torpedo School at the Devonport. In 1923, the Navy decided to retire many of the older destroyers in preparation for the introduction of newer and larger vessels and Satyr was sold to be broken up on 16 December 1926.

HMS Rowena was an R-class destroyer which served with the Royal Navy during World War I. Launched on 1 July 1916, the ship operated as part of the Grand Fleet as part of a destroyer flotilla hunting for German vessels that were attacking convoys in the North Sea. Although there were many reported sightings, no submarines were sunk. After the conflict, the vessel was transferred to the Navy’s establishment at Portland to help in the development of anti-submarine warfare, which ultimately helped in the Battle of the Atlantic. Rowena did not, however, see the fruit of this labour. After twenty years of service, the destroyer was retired and sold to be broken up on 27 January 1937.
