HMS Ivanhoe (D16)

The ship was ordered from Yarrow Shipbuilders at Scotstoun on 30 October 1935 under the 1935 Naval Programme. The ship was laid down on 12 February 1936 and launched on 11 February 1937^[8] as the second Royal Navy warship to carry the name.^[9] Ivanhoe was completed on 24 August 1937 and cost £259,371 excluding items supplied by the Admiralty such as guns and communications equipment.^[8] She was assigned to the 3rd Destroyer Flotilla in the Mediterranean Fleet upon commissioning and participated in training exercises with the French Navy from December to January 1938. The ship was forced to leave these exercises prematurely as she had problems with the tubes in her superheaters, that were replaced at Malta from 15 January – 19 March. Afterwards, Ivanhoe was transferred to Gibraltar where she patrolled Spanish waters enforcing the policies of the Non-Intervention Committee until the end of the war. She was in Cartagena from February to March 1939 to protect British citizens and interests as foreigners, Republican troops and their supporters evacuated the city.^[10]

Ivanhoe was in transit between Alexandria and Malta when the Second World War began in September 1939 but she was in Plymouth on 14 September as the 3rd Destroyer Flotilla had been transferred to the Western Approaches Command for escort duties.^[10] Together with her sisters, Inglefield, Intrepid, and Icarus, the ship sank the German submarine U-45 on 14 October.^[11] She was refitted at Sheerness Dockyard and converted to a minelayer from 14 November to 13 December. Ivanhoe was transferred to the specialist minelaying 20th Destroyer Flotilla on 12 December and laid her first minefield, along with the other three ships of the flotilla, at the mouth of the Ems estuary on the night of 17/18 December. Another minefield was laid on the night of 2/3 January 1940 by Ivanhoe and Intrepid and they then laid a series of anti-submarine minefields later in the month.^[12] The ship replaced her guns and torpedo tubes at Portland from 27 January to 3 February and resumed her former duties.^[10]

In early April, Ivanhoe and three other destroyer minelayers were escorted by the 2nd Destroyer Flotilla as they laid mines as part of Operation Wilfred, an operation to lay mines in the Vestfjord to prevent the shipment of Swedish iron ore from Narvik to Germany. The mines were laid on the early morning of 8 April, before the Germans began their invasion, and the destroyers joined the battlecruiser HMS Renown and her escorts after they each laid their 60 mines. The ship was present during, but played no significant part in, Renown's brief Action off Lofoten with the German battleships Scharnhorst and Gneisenau on 9 April.^[13] Later in the month, the ship carried troops of the 15th Infantry Brigade to Åndalsnes. Ivanhoe then loaded mines and laid a minefield in the approaches to Trondheim, together with Icarus and Impulsive, on the night of 29/30 April.^[14][15]

After a boiler cleaning (7–15 May) Ivanhoe, Esk, and Express, laid 164 mines off the Hook of Holland on the night of 15/16 May. Three German minesweepers were sunk by this minefield on 26 July. Three nights later, the same three ships, reinforced by Intrepid, Impulsive, and the auxiliary minelayer Princess Victoria laid a minefield off the Dutch coast. Princess Victoria struck a German mine on the voyage home and was sunk; the destroyers rescued the ship's survivors. They laid five more minefields off the Dutch coast before the end of the month.^[16] On 29 May, the ship was transferred to the Dunkirk evacuation effort and ferried 930 troops to Dover that day. She also took aboard the crew of the badly damaged destroyer Grafton and then scuttled Grafton. She was withdrawn from the evacuation on 30 May as too valuable to risk, but this decision was reversed the following day and Ivanhoe evacuated 1,290 men to Dover.^[17] On the morning of 1 June, already having loaded troops, the ship was attacked off Dunkirk harbour by German aircraft. Two bombs missed to port and starboard, but the third detonated above the upper deck and flooded the two forward boiler rooms. The bomb killed 26, including five soldiers, and wounded many others.^[10] Most of the troops and wounded were taken off by the minesweeper Speedwell and the destroyer Havant.^[18] No. 3 boiler room was still operable and the ship reached Dover under her own power.^[10]

Repairs at Sheerness lasted until 28 August and she was converted back into a minelayer at Immingham from 28 to 31 August as she was transferred back to the 20th Destroyer Flotilla. That night, she sailed with Intrepid, Icarus, Esk and Express to lay a minefield off the Dutch coast, north of Texel. Express hit a mine in a new German field that night and had her bow blown off. Ivanhoe closed to assist her and struck another mine shortly afterwards. The explosion knocked out her power for several hours, but the ship was able to raise steam by 01:45 on 1 September. She reached a speed of 7 knots (13 km/h; 8.1 mph) while steaming backwards to lessen the stress on her damaged bow. However, about 04:00, either her propellers fell off or her propeller shafts fractured, and she lost all speed. Around 08:00, four motor torpedo boats arrived; three of these loaded all but 37 men of the ship's crew while the fourth stayed with the destroyer to recover the remaining crewmen. Ivanhoe continued to take on water and started to list. Early in the afternoon, she lost all power to her pumps and the captain ordered the ship abandoned after opening her valves to speed her sinking. Shortly afterwards, Ivanhoe was discovered and damaged by a German aircraft, but still did not sink. She had to be scuttled by a torpedo fired by the destroyer Kelvin later in the afternoon.^[19] The ship quickly sank afterwards at position 53°26′42″N 03°45′24″E / 53.44500°N 3.75667°E / 53.44500; 3.75667.^[10]
