Credit River - Shipwreck Series

Glowworm
 April 8, 1940



There are many shipwrecks around the world. Some very famous and others not so. Each however has it’s own story to tell. As you travel along the Credit River doing this series of caches, we have highlighted a number of these shipwrecks. During low water levels on these parts of the Credit River, you need to be careful in a canoe or kayak so as you don’t wind up in your own shipwreck. Besides the many large rocks along the way, there are also some other obstacles such as dams which should be avoided. All of the geocaches in this series have been placed by tubing, inflatable boat or on foot by walking in the water along the Credit River. Whichever way you choose to search for these caches, use caution and common sense.

Glowworm
HMS Glowworm (H92) was a G-class destroyer built for the Royal Navy in the mid-1930s. During the Spanish Civil War the ship spent part of 1936 and 1937 in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. Glowworm was transferred from the Mediterranean Fleet shortly after the beginning of World War II to the British Isles, to escort shipping in local waters. In March 1940, she was transferred to the Home Fleet, just in time to participate in the opening stages of the Norwegian Campaign. On 8 April 1940 Glowworm encountered German destroyers transporting troops to invade Norway in Operation Weserübung. The destroyers attempted to disengage while calling for help from the heavy cruiser Admiral Hipper. Glowworm was heavily damaged by Admiral Hipper, but still attempted to torpedo the German ship. The two ships collided, which broke the bow off Glowworm, and she sank shortly afterwards.

Upon commissioning she was assigned to the 1st Destroyer Flotilla of the Mediterranean Fleet. 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 on her voyage to Aden later that month. During night exercises on 16 May 1939, Glowworm collided with her sister, HMS Grenade, and was forced to put into Alexandria for temporary repairs. She received permanent repairs in Malta between 23 May and 24 June.

Glowworm was in Alexandria when World War II 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, HMS Grafton, and HMS Greyhound. 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.

On 5 April Glowworm was part of the escort of the battlecruiser HMS Renown, along with her sisters Greyhound, HMS Hero, and HMS Hyperion. 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.

On the morning of 8 April 1940 Glowworm was on her way to rejoin Renown when she encountered the German destroyers Z11 Bernd von Arnim and Z18 Hans Lüdemann in the heavy fog before 08:00 a.m. The destroyers were part of a German naval detachment, led by the heavy cruiser Admiral Hipper, on its way to land troops at Trondheim as part of the German invasion of Norway (Operation Weserübung). Glowworm opened fire and the German destroyers attempted to disengage, signalling for help. The request was soon answered by Admiral Hipper which spotted Glowworm at 09:50. Hipper initially had difficulty in distinguishing Glowworm from von Arnim, but opened fire eight minutes later at a range of 8,400 metres (9,200 yd) with her 20.3-centimetre (8.0 in) main guns. Glowworm was hit by Hipper's fourth salvo and she started making smoke. She turned into her own smoke in an attempt to break visual contact with Hipper, but the cruiser's radar-directed guns were not affected by the smoke. When the destroyer emerged from her smoke the range was now short enough that the cruiser's 10.5-centimetre (4.1 in) could fire. Glowworm's radio room, bridge, and forward 4.7-inch gun were all destroyed, and she received additional hits in the engine room, the captain's day cabin, and finally the mast. As this crashed down, it caused a short circuit of the wiring, causing the ship's siren to start a banshee wail. At 10:10 Lieutenant Commander Gerard Broadmead Roope, fired five torpedoes from one mounting at a range of 800 metres (870 yd), but all missed because Captain Hellmuth Heye had kept Hipper's bow pointed at Glowworm throughout the battle to minimize his risk from torpedoes. The destroyer fell back through her smoke screen to buy time to get her second torpedo mount working, but Heye followed Glowworm through the smoke 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 Heye ordered a hard turn to starboard to reduce the range and possibly ram the destroyer. Hipper was slow to answer her helm and Glowworm struck the cruiser just abaft the anchor. The collision broke off Glowworm's bow and the rest of the ship scraped along Hipper's side, gouging open several holes in her hull and destroying her forward starboard torpedo mounting. One German sailor was knocked overboard by the collision. Hipper took on some 500 tonnes (490 long tons) 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.

Admiral Hipper hove to in order to rescue her man overboard and Glowworm's survivors. The German sailor was not found, but 40 British sailors were recovered, although at least six later died of their wounds. Lieutenant Ramsay, the senior surviving officer, told his rescuers that neither the helm nor the emergency rudder were manned when the ships collided so the destroyer's turn towards Hipper was probably accidental. German accounts only mention four torpedoes fired by Glowworm, but British accounts say all eight were fired. This was confirmed by photographic evidence taken after the collision showing all of her torpedo tubes empty.

Glowworm's commanding officer, Lieutenant Commander Roope, who drowned when he could no longer hang on to a rope whilst being pulled up the side of the cruiser, was posthumously awarded the Victoria Cross, thus becoming the first VC recipient of the Second World War. The award was justified, in part, by the recommendation of Captain Heye, who wrote to the British authorities via the Red Cross, giving a statement of the valiant courage Lt Cdr Roope had shown when engaging a much superior ship in close battle. Lieutenant Ramsay was also awarded the DSO. Both awards were made after the end of the war.
