HMS Glowworm (H92)

Glowworm displaced {{convert|1350|LT|t|lk=on}} at standard load and {{convert|1883|LT|t}} at deep load. The ship had an overall length of {{convert|323|ft|m|1}}, a beam of {{convert|33|ft|m|1}} and a draught of {{convert|12|ft|5|in|m|1}}. She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of {{convert|34000|shp|lk=on}} and gave a maximum speed of {{convert|36|kn|lk=in}}. Steam for the turbines was provided by three Admiralty 3-drum water-tube boilers. Glowworm carried a maximum of {{convert|470|LT|t}} of fuel oil that gave her a range of {{convert|5530|nmi|lk=in}} at {{convert|15|kn}}. The ship's complement was 137 officers and men in peacetime.Whitley, pp. 107–08

The ship mounted four 45-calibre 4.7-inch (120 mm) Mark IX guns in single mounts. For anti-aircraft defence Glowworm had two quadruple Mark I mounts for the 0.5 inch Vickers Mark III machine gun. She was the test ship for the new quintuple torpedo tube mounts for British 21 inch torpedo torpedoes. One depth charge rail and two throwers were fitted; 20 depth charges were originally carried, but this increased to 35 shortly after the war began.English, p. 141

Glowworm was ordered from the yards of John I. Thornycroft and Company, at Woolston, Hampshire on 5 March 1934 under the 1933 Construction Programme. She was laid down on 15 August 1934 and launched on 22 July 1935. She was completed on 22 January 1936 at a total cost of £248,785, excluding government-furnished equipment like the armament.English, pp. 89–90 Upon commissioning she was assigned to the 1st Destroyer Flotilla of the Mediterranean Fleet. Between 10 August and 9 September 1936, together with {{HMS|Grafton|H89|2}}, she escorted the yacht Nahlin as King Edward VIII cruised the eastern Mediterranean.{{cite news |title=The King's Holiday |url=https://www.britishnewspaperarchive.co.uk/viewer/bl/0000540/19360806/301/0008 |access-date=21 May 2023 |work=The Scotsman |issue=29077 |date=6 August 1936 |location=Edinburgh |page=8 |via=British Newspaper Archive}}

Glowworm patrolled Spanish waters during the Spanish Civil War, enforcing the edicts of the Non-Intervention Committee until she had a refit at Portsmouth between 27 May and 8 June 1937. The ship returned to the 1st Destroyer Flotilla in the Mediterranean after her brief refit. Glowworm returned to Portsmouth for a longer overhaul between 7 June and 25 July 1938 and escorted the ocean liner SS Strathnaver between Malta and Alexandria during the Munich Crisis in September 1938. She then escorted the light cruiser {{HMS|Arethusa|26|2}} on her voyage to Aden later that month.English, p. 95 During night exercises on 16 May 1939, Glowworm collided with her sister, {{HMS|Grenade|H86|2}} and was forced to put into Alexandria for temporary repairs. She received permanent repairs in Malta between 23 May and 24 June.English, p. 96

Glowworm was in Alexandria when the Second World War began in September 1939. In October the flotilla was transferred to the Western Approaches Command and Glowworm sailed for the UK on 19 October with her sisters {{HMS|Gallant|H59|2}}, Grafton, and {{HMS|Greyhound|H05|2}}. They arrived at Plymouth on 22 October and were deployed in the South Western Approaches. Glowworm carried out convoy escort duties and anti-submarine patrols until 12 November when she was transferred to the 22nd Destroyer Flotilla, based at Harwich, for North Sea patrol and escort duties. On 22 February 1940 she was hit by the Swedish ship Rex in fog whilst at anchor off Outer Dowsing. Glowworm suffered significant structural damage and was under repair at a commercial dockyard in Hull until late March. On completion of the repairs, she was transferred back to the 1st Destroyer Flotilla of the Home Fleet, rejoining the flotilla at its base at Scapa Flow on 20 March.English, pp. 96–97

On 5 April Glowworm was part of the escort of the battlecruiser {{HMS|Renown|1916|2}}, along with her sisters Greyhound, {{HMS|Hero|H99|2}}, and {{HMS|Hyperion|H97|2}}. The ships covered the mine laying operation in Norwegian waters, Operation Wilfred. On 7 April, Glowworm was detached from the task force to search for a man lost overboard.Haarr, pp. 65–66

On the morning of 8 April 1940 Glowworm was on her way to rejoin Renown when she encountered the German destroyers {{ship|German destroyer|Z11 Bernd von Arnim||2}} and {{ship|German destroyer|Z18 Hans Lüdemann||2}} in the thick fog before 8:00 a.m. The destroyers were part of a German naval detachment, led by the heavy cruiser {{ship|German cruiser|Admiral Hipper||2}}, on its way to land troops at Trondheim as part of Operation Weserübung, the German invasion of Norway. Glowworm opened fire and the German destroyers attempted to disengage, signalling for help. The request was soon answered by Admiral Hipper and Glowworm was spotted at 09:50. Hipper had difficulty in distinguishing Glowworm from von Arnim but opened fire eight minutes later at a range of {{cvt|8400|m}} with the {{convert|20.3|cm|adj=on}} main armament.Haarr, 2009, p. 93

Glowworm was hit by Hipper{{'}}s fourth salvo and she made smoke and turned into it but the cruiser's radar-directed guns were not affected by the smoke. When the destroyer emerged from the smoke the range was short enough for the cruiser's {{convert|10.5|cm|adj=on}} guns to open fire. Glowworm{{'}}s radio room, bridge, and forward 4.7-inch gun were destroyed and she received more hits in the engine room, the captain's day cabin and the mast. As the mast fell it caused a short circuit of the wiring and the ship's siren turned on.Haarr, 2009, p. 93

At 10:10, Lieutenant Commander Gerard Roope fired five torpedoes from one mounting at a range of {{cvt|800|m}}. The torpedoes missed because Captain Hellmuth Heye had kept Hipper{{'}}s bow pointed at Glowworm to minimize the risk from torpedoes. The destroyer fell back through her smokescreen to buy time to get her second torpedo mount working but Heye followed Glowworm to finish her off before she could fire the rest of her torpedoes. The two ships were very close when Hipper emerged from the smoke, and Roope ordered a hard turn to starboard to ram the cruiser. Hipper was slow to answer her helm and Glowworm struck the cruiser just abaft of the anchor.Haar, pp. 91–95

The collision broke off Glowworm{{'}}s bow and the rest of the ship scraped along Hipper{{'}}s side, gouging several holes in the cruiser's hull, destroying her forward starboard torpedo mounting, and one of her sailors was lost overboard. Hipper took on some {{cvt|500|t}} of water before the leaks could be isolated but was not seriously damaged. Glowworm was on fire when she drifted clear and her boilers exploded at 10:24, taking 109 of her crew with her.Haar, pp. 91–95

Admiral Hipper hove to and began to rescue survivors. The German sailor was not found but forty British sailors were recovered, although at least six later died of their wounds. The senior surviving officer, Lieutenant Ramsay, told his rescuers that neither the helm nor the emergency steering was manned when the ships collided. German accounts only mention four torpedoes fired by Glowworm but British accounts say all ten were fired. This was confirmed by photographic evidence taken after the collision showing empty torpedo tubes.Haar, pp. 94–95, 431 Roope drowned when he could no longer hang on to a rope whilst being pulled up the side of the cruiser.Haarr, p. 96

Roope posthumously was awarded the Victoria Cross, becoming the first VC recipient of the Second World War.Haarr, p. 96 The award was justified, in part, by the recommendation of Heye, who wrote to the British authorities via the Red Cross, stating the dauntless courage Roope had shown when engaging a much superior ship at short range. Ramsay was awarded the DSO; the awards were made after the end of the war.[https://www.thegazette.co.uk/London/issue/37170/supplement/3557 London Gazette]
