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. [4] 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.

Contents

Captured during the German invasion of Norway, she was pressed into service in an attempt to mine Sognefjord. After attacks by Norwegian aircraft and ships she took no further part in the conflict. After the war she was returned briefly to the Royal Norwegian Navy then entered civilian service in a number of roles over the years.

Characteristics

The main gun of the ship was 7.8m meters long, [5] or about a quarter of the length of the whole vessel. In addition she was armed with three revolving guns for closer ranges.

Shortly before the First World War, Tyr was rebuilt as a minelayer. During this rebuild, the heavy gun was replaced with a more modern 12 cm breech-loader, and one of the 37 mm guns was replaced with a more potent 76 mm gun. After the heavy gun and ammunition were removed, she could carry 55 mines.

By 1940, two Madsen machine guns had been added for anti-aircraft purposes. [6]

Service

German invasion of Norway

Mining the Bergen approaches

On 9 April 1940, the day of the German invasion of Norway, the commander of Lerøy guard district, Captain F. Ulstrup, received a message informing him that German warships had forced their way past the small Lerøy Fort on their way towards Bergen. Captain Ulstrup immediately boarded Tyr and sailed out to mine the Lerøyosen approaches to the south-western Norwegian city. At 0130hrs the Norwegian minelayer began mining the stretch of water between Lerøy island and Sotra, putting out seven mines right before the German invasion flotilla arrived at Lerøyosen. Making good her escape Tyr placed another sixteen mines in the Vatlestraumen approaches north of Bergen. [7] [8]

Due to a built-in time delay the Lerøyosen mines were not active when the German warships passed over them. However by the time the supply fleet of the German forces in the Bergen area started coming into Lerøyosen late in the evening the mines were ready. [7] The first ship to hit the mines was the 4,297 ton supply ship Sao Paulo, [7] [9] [10] which sank with a great loss of both lives and materiel at 2300hrs, 9 April. As the mine barrier had now been discovered the Kriegsmarine needed to sweep the Lerøyosen but had no dedicated minesweepers in the area. In an improvised reaction to the mines the invaders sent out the naval trawlers Schiff 9 and Cremon, [10] together with two launches from the depot ship Karl Peters. The improvised minesweeper force entered the mine barrier in the evening of 10 April and began clearing the mines. At 1925hrs Schiff 9 struck a mine and went down in between one and two minutes. At 19.30 hours as Cremon tried to rescue survivors she too blew up together with one of the two launches.

Later on 27 April the 8,500 ton German merchant ship Liege was sunk by one of the mines. The 4,601 ton German steamer Johann Wessels was damaged by one of the mines on 5 May 1940. [9] Three days later, on 8 May 1940, the 1,151 ton German-controlled Danish steamer Gerda hit a mine and sank. [11] All in all the Germans lost three supply ships, two naval trawlers and a launch sunk by mines laid by Tyr. [12]

Guarding the southern sea lane

After laying her mines Tyr resumed guarding the southern sea lane to Bergen and soon met up with German naval forces. Off the island of Skorpo she had a clash with an E-boat, neither vessel being hit. Tyr then withdrew behind the cover of Forstrøno island, but was chased down by a further three German E-boats. After a brief fight Tyr drove the enemy ships off, damaging one of the German vessels severely with a 37 mm shell. [12]

Norwegian Campaign

To the Hardangerfjord, change of command

Later in the Norwegian Campaign, on 16 April, Tyr moved to Uskedal in Ytre Hardangerfjord, where her captain became the commander of the newly created Hardangerfjord naval district. The second-in-command, Sub-Lieutenant K. Sandnæs, took over the minelayer. While in the Hardangerfjord she took part in the Battle of Uskedal in the early hours of 20 April.

Battle of Uskedal

From her anchorage south of Uskedal Tyr first damaged an E-boat and then, with her 12 cm main gun, put a large hole below the waterline of the armed trawler Schiff 18 forcing her to be beached to avoid sinking. At 05.30 a.m. the battle turned against the Norwegians as another trawler, Schiff 221 landed more troops at Trones which advanced on Uskedal from a new direction. All the while during the battle Tyr was providing naval gunfire support from her position in the Storsund midway between Uskedal and Herøysund, bombarding the Germans with high explosive shells. Even though she came under heavy machine gun fire from German troops, Tyr helped the Norwegian land forces hold their ground until taken by surprise by the sudden arrival of the German artillery training ship Bremse. Fire from the larger enemy ship forced Tyr to back out the fight and go to the docks in Uskedal. After a short while at anchor Tyr was ordered back into the fight to help the torpedo boat Stegg that was fighting Bremse. Once Tyr returned to the battle she again gained the attention of the German warship and was forced to take cover in a small bay at Skorpo. As Sub-Lieutenant Sandnæs now considered the battle as hopeless he ordered his crew ashore to rest, also sending small arms and ammunition on land. Sandnæs started preparations to scuttle his ship with explosives, but before he could carry out his intentions two E-boats entered the bay and boarded Tyr. Before long Schiff 221 arrived and took Tyr in tow. By afternoon Tyr was on her way back to Bergen with a German crew.

German service

Sognefjord with Uller

In German hands Tyr was first used together with fellow captured Norwegian minelayer Uller in a plan by Admiral Otto von Schrader to mine the entrance to the Sognefjord on 30 April. Together the two ships could carry 80 mines and quite effectively block in the Norwegian naval forces in the country's longest fjord. However, the Norwegian forces in the fjord had a very effective system of look-outs and guard ships. Before the two minelayers even had entered Sognefjord they were attacked by two of the Royal Norwegian Navy Air Service's M.F.11 biplane patrol aircraft. The seaplanes dropped nine bombs at the two minelayers, failing to damage either of the ships but wounding three sailors on Uller with shrapnel. Having escaped damage in this attack the minelayers continued north and started laying mines at the entrance to the Sognefjord. In the early hours of 1 May the Norwegians threw another seaplane attack against the German mining operation. A single Norwegian Heinkel He 115 made two dive bombing attacks on Tyr and Uller, dropping one 250 kg bomb and four 50 kg bombs on the fiercely resisting ships. None of the bombs were direct hits, but one near miss damaged the side of Uller, causing sea water to flood into her. Uller had to be beached on Losneøy island and thereafter scuttled by the only slightly damaged Tyr.[ citation needed ]

Ambush

After scuttling Uller, Tyr abandoned her mining mission and retreated southwards to Bergen, carrying the crew of Uller with her. Norwegian scouts were however still following her. Before the minelayer got back to base she was ambushed in the Fålefotsundet narrows between Hisøya and the mainland by the crew of a Norwegian guard boat that had been stalking her since leaving the Sognefjord. The crew had taken up positions on both sides of the narrows and opened a harrowing fire on the minelayer as she passed through. [12] As Tyr was shot up with intense machine gun fire the German crew replied with her 12 cm main gun and automatic weapons without hitting any in the ambush force. The fire fight continued until Tyr had passed through the narrows and got out of range of the Norwegians' light weaponry, making it back to Bergen. Tyr saw no further service during the Norwegian Campaign.

After the Fålefotsundet ambush Tyr took no further part in the Norwegian Campaign. What the Germans used the minelayer for after that is unknown.[ citation needed ]

Post war

After the Second World War, Tyr was returned to the Royal Norwegian Navy, and sold into civilian service. Her first rebuild was in 1946 when she converted to a heavy lift steamship. In 1949 she was sold to Br. Wilhelmsen A/S and rebuilt as a car ferry, being renamed Bjørn West in 1951 and was used as such by different companies for many years. In May 1986 she was rebuilt at Karmøy, this time as a heavy-transport ship. Later she was sold to a salmon farm company and as of 2006 was still in existence as a floating storage vessel, at last report entering Eidsvik shipyard in May 2014 for restoration. [13]

The German operation for the invasion of Denmark and Norway in April 1940 was code-named Weserübung, or "Weser Exercise." Opposing the invasion were the partially mobilized Norwegian military, and an allied expeditionary force composed of British, French, and Free Polish formations. The following list formed the order of battle for this campaign.

HNoMS <i>Draug</i> (1908)

HNoMS Draug was the lead ship of the three-ship Draug class of destroyers built for the Royal Norwegian Navy in the years 1908–1913. The four-stacked destroyer was kept in service long after she was obsolete, and took part in the defence of Norway during the German invasion in 1940.

HNoMS <i>Garm</i> (1913)

HNoMS Garm was the third destroyer built for the Royal Norwegian Navy, and was a Draug class destroyer. Garm was constructed several years after her two sister ships, but to the same plans. She was built at the naval shipyard in Horten, with yard number 107.

HNoMS <i>Vale</i> (1874)

Gunboat Vale was a Vale-class Rendel gunboat built for the Royal Norwegian Navy at Karljohansvern Naval Yard in 1874. She was one of a class of five gunboats - the other ships in the class was Brage, Nor, Uller and Vidar.

HNoMS <i>Uller</i> (1876)

HNoMS Uller was a Vale-class Rendel gunboat constructed for the Royal Norwegian Navy at Karljohansverns Verft Naval Yard in Horten in 1874-1876 and had yard build number 55. She was one of a class of five gunboats - the other ships in the class were Vale, Brage, Nor and Vidar.

The HNoMS Gor was a Gor-class Rendel gunboat built for the Royal Norwegian Navy at Karljohansvern Naval Yard in Horten in 1884. She was one of a class of two gunboats - the other ship in her class being Tyr. The Gor and Tyr can be seen as improved Vale-class gunboats.

HNoMS <i>Olav Tryggvason</i> 1931 Norwegian/German minelayer

HNoMS Olav Tryggvason was a minelayer that was built by the naval shipyard at Horten in the early 1930s with the yard number 119. She served in the Royal Norwegian Navy until captured by the Germans in 1940. The Germans renamed her first Albatros II, and a few days later Brummer. She was wrecked in a British bombing raid in northern Germany in April 1945.

HNoMS <i>Sleipner</i> (1936)

HNoMS Sleipner was a destroyer commissioned into the Royal Norwegian Navy in 1936. The lead ship of the Sleipner class, she gained near-legendary status in Norway by enduring over two weeks of intense air attack by Luftwaffe bombers following the 9 April 1940 invasion of Norway. After the resistance in South Norway started unravelling she made her way over the North Sea to continue the fight against the Germans from exile. After serving as a convoy escort along the coast of the United Kingdom, she was decommissioned in 1944. She was recommissioned in 1948 after being converted to a frigate. Along with her surviving sister ships she was sold for scrapping in 1959.

HNoMS <i>Rauma</i> (1939)

HNoMS Rauma 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 Kamerun, she was returned to the Norwegians after the end of the Second World War and recommissioned in 1947. Rauma remained in service until being sold for scrapping in 1963.

HNoMS <i>Stegg</i> (1921)

The last of the Trygg class of Royal Norwegian Navy torpedo boats was HNoMS Stegg. Her sister ships were Trygg and Snøgg. The Trygg class vessels were the only additions to the Norwegian fleet of torpedo boats between the First and the Second World Wars. At the outbreak of the Second World War the Trygg class was mobilised together with eight 2. class and six 1. class torpedo boats.

HNoMS <i>Nordkapp</i>

HNoMS Nordkapp was the lead ship of the Nordkapp class of fishery protection vessels. She was launched 18 August 1937 at Horten naval shipyard, with yard number 123. She had one sister ship, HNoMS Senja. Nordkapp was named after the North Cape in Finnmark. As was typical of her class, Nordkapp was very unstable in rough seas and was viewed from the beginning as a second-rate vessel. Nordkapp sailed throughout the Second World War and saw service in several theatres.

<i>Trygg</i>-class torpedo boat

The Trygg class was the third and last class of torpedo boats to be built for the Royal Norwegian Navy. The three Trygg ships were constructed from 1919 to 1921 at Moss Verft in Moss (Trygg) and Horten naval yard.

HNoMS <i>Sæl</i>

HNoMS Sæl was the penultimate vessel of the ten 1. class torpedo boats of the Royal Norwegian Navy. She was built at the Royal Norwegian Navy Shipyard in Horten in 1901, with yard number 85. She was to see close to 40 years service with the Royal Norwegian Navy, taking part in the preparations for war in connection with the dissolution the union with Sweden in 1905, enforcing Norwegian neutrality during the First World War and opposing the German invasion of Norway in 1940. She was lost in battle with Kriegsmarine vessels at Ånuglo in the Hardangerfjord on 18 April 1940.

HNoMS <i>Honningsvåg</i> Naval trawler

HNoMS Honningsvåg was a naval trawler that served throughout the Second World War as a patrol boat in the Royal Norwegian Navy. She was launched at the North Sea harbour of Wesermünde in Hanover, Germany in February 1940 as the fishing trawler Malangen and was captured by Norwegian militiamen at the North Norwegian port of Honningsvåg during her maiden fishing journey to the Barents Sea. Having taken part in the defence of Norway in 1940 she spent the rest of the war years patrolling the ocean off Iceland. She was decommissioned in 1946, sold to a civilian fishing company in 1947 and scrapped in 1973.

German submarine U-137 was a Type IID U-boat of Nazi Germany's Kriegsmarine in World War II. Her keel was laid down on 16 November 1939 by Deutsche Werke in Kiel. She was launched on 18 May 1940 and commissioned on 15 June 1940 with Oberleutnant zur See Herbert Wohlfarth in command.

Yugoslav minelayer <i>Zmaj</i> Yugoslav Royal Navy minelayer

Zmaj was built in Germany as a seaplane tender for the Royal Yugoslav Navy between 1928 and 1930. She does not appear to have been much used in that role and was converted to a minelayer in 1937. Shortly before the Axis invasion of Yugoslavia in April 1941, she laid minefields along the Dalmatian coast, perhaps inadvertently leading to the sinking of two Yugoslav passenger ships. Slightly damaged by Italian dive bombers and then captured by the Italians during the invasion, she was soon handed over to the Germans. While in their service the ship was renamed Drache, had her anti-aircraft (AA) armament improved, and was used as a seaplane tender and later as a troop transport. In the latter role she participated in over a dozen convoys between the Greek port of Piraeus and the Greek island of Crete between December 1941 and March 1942.

HNoMS <i>Storm</i> (1898) Norwegian torpedo boat

HNoMS Storm was a 1.-class torpedo boat constructed in 1898. Storm served the Royal Norwegian Navy for almost 42 years, including neutrality protection duties during the First World War. She was lost in the 1940 Norwegian campaign of the Second World War. During the Norwegian Campaign, she was the only Norwegian warship that launched a torpedo against the invading Germans.

HNoMS <i>Brand</i> (1898)

HNoMS Brand was a 1.-class torpedo boat constructed in 1898. She served the Royal Norwegian Navy for more than four decades, including neutrality protection duties during the First World War. Having once again been employed on neutrality protection duty at the outbreak of the Second World War, Brand was captured by the Germans during their invasion of Norway in April 1940.

V 105 Cremon was a German trawler built in 1922 which was converted into a Vorpostenboot for the Kriegsmarine during World War II.
