HMS Ivanhoe was an I-class destroyer built for the Royal Navy in the mid-1930s. During the Spanish Civil War of 1936–1939, the ship enforced the arms blockade imposed by Britain and France on both sides as part of the Mediterranean Fleet. Before the start of World War II, the ship was modified so that she could be used to lay mines by removing some of her armament. Ivanhoe was transferred to Western Approaches Command shortly after the war began and helped to sink one German submarine in October 1939. She was converted to a minelayer while undergoing a refit in November–December and laid minefields in German coastal waters as well as anti-submarine minefields off the British coast until she was reconverted back to her destroyer configuration in February 1940. Ivanhoe reverted to her minelaying role during the Norwegian Campaign in April 1940 and then laid a number of minefields off the Dutch coast during the Battle of the Netherlands in May. The ship participated in the Dunkirk evacuation until she was badly damaged by German aircraft on 1 June. On her first minelaying mission after her repairs were completed, she struck a German mine and had to be scuttled on 1 September 1940 during the Texel Disaster.
HMS Express was an E-class minelaying destroyer built for the Royal Navy in the early 1930s. Although assigned to the Home Fleet upon completion, the ship was attached to the Mediterranean Fleet in 1935–36 during the Abyssinia Crisis. During the Spanish Civil War of 1936–39, she spent considerable time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict.
HMS Western Isles was a command ship of the Royal Navy during World War II, serving as the flagship of the Anti-Submarine Training School at Tobermory on the Isle of Mull under Vice Admiral Gilbert Stephenson. Launched in 1902 as the Dutch Batavier Line passenger ship Batavier IV, after the war she served in the Royal Netherlands Navy as the training ship Hr. Ms. Zeearend. She was decommissioned in 1970, and scrapped in 1972.
The Romanian Navy is the navy branch of the Romanian Armed Forces; it operates in the Black Sea and on the Danube. It traces its history back to 1860.
The E and F-class destroyers were a group of 18 destroyers built for the Royal Navy during the 1930s. The ships were initially assigned to the Home Fleet, although they reinforced the Mediterranean Fleet during the Italian invasion of Abyssinia of 1935–36 and enforced the Non-Intervention Agreement during the Spanish Civil War of 1936–1939. After the beginning of the Second World War in August 1939, the E-class ships were mostly assigned to escort duties under the Western Approaches Command, while the Fs were assigned to escort the ships of the Home Fleet. Between them they sank four German submarines through March 1940 while losing only one ship to a submarine.
HMS P41 was a Royal Navy U-class submarine built by Vickers-Armstrong. She was transferred to the exiled Royal Norwegian Navy before completion and renamed HNoMS Uredd. She and one of the B-class in 1940 have so far been the only Norwegian submarines to have been sunk.
HNoMS Tyr was a Gor-class Rendel gunboat built for the Royal Norwegian Navy at Karljohansverns Verft Naval Yard in Horten. She was laid down in 1884 and launched in 1887 with build number 67. Tyr was one of a class of two gunboats - the other ship in her class being HNoMS Gor. Gor and Tyr can be seen as improved Vale-class gunboats, of 290 tons instead of the 250 tons standard for that class.
HMAS Bungaree was an auxiliary minelayer of Royal Australian Navy (RAN), serving during World War II. The ship was built as a cargo vessel for the Adelaide Steamship Company by Caledon Shipbuilding & Engineering Company at Dundee, and launched in 1937. The ship operated in Australian waters and was requisitioned by the RAN in October 1940. Decommissioned on 7 August 1946 and returned to her owners on 5 November 1947, she was sold in 1957 and renamed Dampier. She was then sold in 1960 and renamed Eastern Mariner and while operating in South Vietnamese waters she struck a mine on the Saigon River and was sunk on 26 May 1966. She was salvaged by a Japanese company and subsequently scrapped in 1968.
HNoMS Otra was an Otra-class minesweeper built in 1939 for the Royal Norwegian Navy. Captured by the Germans during the 1940 invasion of Norway and renamed Togo, she was returned to the Norwegians in 1946. Otra remained in service until being sold for scrapping in 1963.
HNLMS Zwaardvisch (S814) was the lead ship of the Royal Netherlands Navy's Zwaardvisch-class submarine, which was based on the British T class. The submarine was originally ordered as HMS Talent (P322) and built by Vickers Armstrong, Barrow. It served mainly in the Pacific against the Japanese during the war, operating under both British and US operational command in Ceylon and Australia. In 1950, the vessel was renamed HNLMS Zwaardvis. She was sold and broken up for scrap in 1963.
HMS Esk was an E-class destroyer built for the Royal Navy in the early 1930s. She was designed to be easily converted into a fast minelayer by removing some guns and her torpedo tubes. Although assigned to the Home Fleet upon completion, the ship was attached to the Mediterranean Fleet in 1935–36, during the Abyssinia Crisis. During the Spanish Civil War of 1936–1939, she spent considerable time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. Esk was converted to a minelayer when World War II began in September 1939, and spent most of her time laying mines. During the Norwegian Campaign of April–June 1940, the ship laid mines in Norwegian territorial waters before the Germans invaded, but was recalled to home waters to resume her minelaying duties in early May. During one such sortie, Esk was sunk during the Texel Disaster on the night of 31 August 1940, when she ran into a newly laid German minefield.
HMS M29 was a Royal Navy M29-class monitor of the First World War. The ship was constructed by Harland & Wolff, in Belfast and launched on 22 May 1915, she was completed in June 1915. During World War I, the monitor served in the Mediterranean Sea at the Battle of Jaffa in 1917 and took part in operations in support of British and White Russian forces in the White Sea during the Russian Civil War in 1919. The ship was then converted to a minelayer and renamed HMS Medusa in 1925. In 1941 Medusa was converted to a repair and depot ship and was renamed HMS Talbot, then renamed HMS Medway II in 1944. In 1946, the vessel was sold for scrap.
The Douwe Aukes class were two minelayers of the Royal Netherlands Navy. The two ships were built at the Gusto shipyard in Schiedam. Construction began in 1919 and was completed in 1922. Built to serve in the Dutch territorial waters, both ships were still in service during the Second World War and they both escaped to the United Kingdom, HNLMS Douwe Aukes on 14 May and HNLMS Van Meerlant on 18 May 1940. Both vessels were transferred to the British Royal Navy. Van Meerlant was sunk by a mine in 1942 while in British service. Douwe Aukes was returned to the Royal Netherlands Navy following the war and was used as a depot ship until sold for scrap in 1962.
The Hydra class were two minelayers of the Royal Netherlands Navy, built to serve in the Dutch East Indies and Dutch territorial waters in Europe. The construction of the ships began in 1910 and was completed in 1912. The ships were built by the navy yard (Rijkswerf) in Amsterdam. Both ships were still in service during the Second World War. Only Medusa escaped to the United Kingdom, however. Hydra was lost after the ship was fired on by an anti-tank weapon. The minelayer sank in the waters off Zeeland.
HMS Latona was an Abdiel-class minelayer of the Royal Navy. She served briefly during the Second World War, but was sunk less than six months after commissioning.
HNLMS Douwe Aukes was a minelayer of the Royal Netherlands Navy. She was built in the Gusto shipyard at Schiedam as the lead ship of the Douwe Aukes class, and one of her early commanders was Eugène Lacomblé.
HNLMS Van Meerlant was a minelayer of the Royal Netherlands Navy built in the Gusto shipyard at Schiedam as part of the Douwe Aukes class.
HNLMS Willem van der Zaan (ML-2/N82/F824/A880) was a minelayer of the Royal Netherlands Navy that was commissioned only days before the start of World War II in September 1939. She served in England, in the Netherlands East Indies, and as a convoy escort in the Indian Ocean before returning to The Netherlands in 1945. She then served again in the Netherlands East Indies and Dutch West Indies until 1950 when she was rebuilt and reclassified as a frigate. From 1961 she was used as an accommodation and repair ship until struck in 1970 and sold for scrap. She was named in honour of the 17th century Schout-bij-nacht Willem Van Der Zaan.
The Hydra class were a class of three paddlewheel steam sloops of the British Royal Navy. They saw active service variously in the Baltic during the Crimean War, against Ottoman forces in Syria and against slavers in West Africa. Latterly Hydra and Hecate were used for survey in the Mediterranean, the Pacific, Australia and the Atlantic, and thus their names were re-used for the Hecla-class survey vessels in the late 20th century. Two of the class were broken up after more than twenty-five years of service, and Hecla was sold for commercial use in 1863.
