Canmlwyddiant y Cwt Nissen

Ffotograff: Dau Gwt Nissen yn Nepo Arfau’r Llynges Frenhinol (RNAD), Trecŵn, Sir Benfro, NPRN 96059

Un o adeiladweithiau milwrol mwyaf adnabyddus y byd yw’r Cwt Nissen. Cafodd y dyluniad syml ar siâp hanner silindr ei ddatblygu gan ŵr o dras Ganadaidd-Americanaidd, y Capten Peter Norman Nissen, o 29ain Cwmni y Peirianwyr Brenhinol, ym 1916.

Cafodd y cytiau eu defnyddio gyntaf yn nes ymlaen yn y flwyddyn honno yn Hesdin, Ffrainc. Byddai’r cytiau ysgafn, rhad a symudol yn cael eu cynhyrchu mewn tri lled – 16, 24 a 30 troedfedd – a châi’r adrannau mewnol eu gosod ar 6 throedfedd fel bod modd creu cwt o unrhyw hyd yn ôl y gofyn. Gallai un lori fyddin 3 tunnell gludo’r uned safonol gyfan. Roedd y llwyth yn cynnwys haen allanol o haearn rhychiog, leinin mewnol o bren, fframiau metel ar ffurf hanner cylch, drws pren, a ffenestri oelcloth. Gallai tîm arbenigol o chwe dyn godi cwt ar sylfaen goncrit barod mewn pedair awr. Yr amser byrraf ar gyfer codi cwt oedd 1 awr 27 munud. Amcangyfrifir i 100,000 o unedau gael eu cynhyrchu yn ystod y rhyfel.

Roedd y Cytiau Nissen yn cwrdd â’r galw am adeiladau dros dro i gartrefu’r miloedd ar filoedd o filwyr a oedd newydd ymuno â’r fyddin. Roedd y dyluniad hyblyg yn golygu y gallai’r cytiau gael eu defnyddio hefyd fel ceginau, ystafelloedd bwyta, storfeydd, gorsafoedd trin clwyfau, eglwysi ac ati.

Lluniad: O Gasgliad Medwyn Parry.

Roedd Nissen wedi codi patent am ei ddyluniad yn y DU, Awstralia, De Affrica, Canada a’r Unol Daleithiau. Ond gwrthododd unrhyw freindaliadau yn ystod y Rhyfel Byd Cyntaf, a gwnaeth y cwmni gweithgynhyrchu yr un peth eto yn ystod yr Ail Ryfel Byd.

Nid Capten Nissen oedd yr unig un a fu’n datblygu cytiau dros dro yn ystod y Rhyfel Byd Cyntaf. Enghreifftiau eraill oedd Cytiau Armstrong, Cytiau Aylwin, Cytiau Forest, Cytiau Cludadwy Tarrant, a Chytiau Weblee, yr oedd pob un ohonynt wedi’u henwi ar ôl swyddogion gyda’r Peirianwyr Brenhinol. Cafodd dyluniadau tebyg eu datblygu yn ystod yr Ail Ryfel Byd hefyd, er enghraifft, Cytiau Abbey, Cytiau Iris, Cytiau Romney, a Chytiau Tufton. Ond nid oedd yr un o’r rhain mor hollbresennol ag un o glasuron dylunio mwyaf yr ugeinfed ganrif, y “Cwt Nissen” eponymaidd. Mae’r cysyniad syml wedi parhau i gael ei ddefnyddio am ganrif bron, heb unrhyw newid i’w siâp sylfaenol.

Royal Commission gains Heritage Lottery Fund approval for the development of ‘The Forgotten U-boat War around the Welsh Coast’ Project

The Royal Commission, in partnership with Bangor University and the Nautical Archaeology Society, have been given a grant to pursue the development of a new Great War commemoration project.

Some 170 shipping and aircraft losses relating to war at sea are recorded in the National Monuments Record of Wales. Each site has the potential to act as a focus for commemoration, but 14 have initially been selected for underwater exploration to enable the Great War story to be told from both the Allied and German perspectives. The sites include British and German submarines; HMS PENSHURST - the Royal Navy's most successful Q-ship or decoy vessel; HMS DERBENT a tanker which played an important part in refuelling naval vessels in the Mediterranean during the Gallipoli campaign; large merchant ships carrying Welsh coal to key theatres of the war as well as coasting vessels from the last days of sail.

The new underwater survey data will be combined into 3D interactive models to be displayed on a dedicated website.

After 100 years underwater, the wrecks have become fabulously rich colonies of marine life. It is hoped that the project will provide opportunities for volunteers to assist with species identification.

The project has been developed in collaboration with Welsh museums and the Archives Network Wales, whose kind letters of support have provided a great deal of inspiration for the initial work programme. It is hoped that many of the project’s outreach activities will be linked into maritime museums, with each participating group having the opportunity to contribute a display panel to a mobile exhibition. The exhibition will be launched at a conference in 2018.

Remembering those who gave their lives for their country, and who have no grave but the sea.

In March 1915, the DERBENT was in the Mediterranean at Port Mudros and Tendos refuelling naval vessels such as HMS PHAETON and HMS INFLEXIBLE, which were attempting to seize control of the Dardanelles Straits during the Gallipoli Campaign.

FISHING NEWS Provides Confirmation of Identity of Lost Admiralty Trawler

First published in 1913, the long running news weekly of the fishing industry has helped to untangle the identify of a steam drifter, which was lost whilst tasked with deploying anti-submarine nets at the entrance to Milford Haven.

The Royal Commission’s ongoing project researching shipping losses relating to the Great War had discovered some confusion in sources about the origins of the fishing vessel. Staff at the Grimsby Fishing Heritage Centre had records which showed that the LADYSMITH was returned to its owners, Henry Taylor and Henry Hopwood, in 1919, so could not have been lost on 27 December 1915. However, members of staff at the Scottish Fisheries Museum were able to put Commission staff onto the right track – a steam drifter (fishing number BF1528) with close associations to the fishing community of the Moray Firth. Two short articles in early editions of this well-known fishing weekly provided confirmation.

Two Scottish fishing vessels, LADYSMITH and FERNDALE, had been put to use as armed patrol vessels/minesweepers and net layers. It would seem that the skippers of both had determined to run for the shelter of the Haven during a gale, but in attempting the heavy seas breaking at the entrance both came to grief. A crewman was washed overboard from the FERNDALE and, as the vessel stopped to attempt a rescue, it was driven onto the rocks off St Ann’s Head. What happened to the LADYSMITH is uncertain, but the reporting in FISHING NEWS reveals how devastating the loss was to three Scottish fishing families.

Just before the Great War, the British fishing fleet was vast. As early as 1908, the Admiralty had begun developing plans to ‘call up’ men to man the trawlers that it had ordered to help counter the increasing menace of sea-mines. These plans included requisitioning commercial vessels should the need arise. Some 150 vessels were thought to be all the Admiralty would need to complete its Royal Naval Patrol Service. However, by the end of the war, over 1,800 had requisitioned and the thousands of the fishermen who formed the core of their normal crews had been employed in theatres of war all around the world. http://www.peoplescollection.wales/items/495674

A very special thanks to the editorial team of Fishing News for allowing us to add a copy of the article to the ‘Great War at Sea’ collection on the People’s Collection Wales website.

Remembering all who gave their lives for their country and have no grave but the sea.

One Hundred Years Ago This Christmas Day…

Local Borth seaman, Richard Davies, of the Royal Naval Reserve, was one of the trawler crewmen who crossed to the VAN STIRUM

… four crewmen belonging to a Royal Naval Auxiliary Fleet trawler were fighting their way through heavy seas in a small boat to reach the stricken VAN STIRUM steamship. After getting on board and touring the ship to assess the damage, they found the tables in the saloon laid for Christmas dinner – but no sign of the crew. 

It would be nearly a year before they received a letter of thanks from the Admiralty for their attempts to save the ship and that the full story of the loss the VAN STIRUM was finally told.

Eight miles south-southwest of the Smalls, whilst carrying a general cargo from London to Rouen, the steamship was spotted by U-24. This German submarine, under the command of Kapitänleutnant Rudolk Scheider, had been responsible for sinking the British battleship HMS FORMIDABLE 12 months earlier off Portland Bill. The captain of the VAN STIRUM attempted to escape pursuit, but ultimately had no option but to order his crew to abandon ship. The two crewmen left on board to lower the lifeboats were killed when the torpedo struck.

The U-boat commander also fired shells at the ship; and yet, despite this damage, the VAN STIRUM remained afloat until later in the day, when it was spotted by the trawler. The lieutenant in charge sent four men to put the steamship under tow. Although their small row boat was smashed against the side of the steamship, they were successful in setting up the towing hawser. However, they soon found that the VAN STIRUM’s steering gear was jammed – the ship would not be controllable when it was underway.

With the VAN STIRUM lurching heavily and sinking ever lower, the four crewmen had to wait for another of the trawler’s small row boats to row across. No sooner had this boat hauled alongside, than the VAN STIRUM rolled over. The four rescuers managed to slide down the ship's side to be picked up by their comrades before the steamship finally sank.

Extract from the Cambrian News, 22 September 2016, regarding the loss of the VAN STIRUM

The two VAN STIRUM crewmen killed in the torpedo attack were W.A. Belanger, Boatswain, and J.T. Hetherington, ordinary seaman.

One Hundred Years Ago Today…

During his first cruise in homes water, April–August 1915, Max Valentiner and U38 accounted for five trawlers, three sailing vessel and 22 merchant ships. Valentiner would go on to become the third most successful u-boat commander of the Great War (144 vessels sunk, six damaged and three taken as prizes).

… Max Valentiner, one of the ablest and most ruthless commanders in the German submarine service, brought U38 to the narrowing of the shipping lanes in St George’s Channel (between Cardigan Bay and the Tuskar Rock lighthouse, Ireland).

Over the next 24 hours, the submarine would sink 10 merchant ships and fishing vessels causing the loss of two lives.

The vessels were:

• BONNY, 2702 ton British steamship operated by the British & African Steam Navigation Co. Ltd (Elder Dempster Line);
• GEORGE BAKER, a British steam drifter owned by E. A. Baker of Great Yarmouth (NPRN 516131); http://www.coflein.gov.uk/en/site/516131/details/UNNAMED+WRECK/
  
  
• GLENBY, 2196 ton British steamship owned by R. Ropner & Co, West Hartlepool, and carrying coal from Cardiff to Archangelsk (NPRN 274830); http://www.coflein.gov.uk/en/site/274830/details/GLENBY/
  
  
• ISIDORO , 2044 ton Spanish-owned steamship carrying iron ore from Bilbao to Glasgow;
• KIRKBY, 3034 ton British steamship also owned by R. Ropner & Co, West Hartlepool, carrying coal from Barry (NPRN 274829); http://www.coflein.gov.uk/en/site/274829/details/KIRKBY/
  
  
• MAGGIE, small British steamship, on passage from Youghal to Fleetwood;
• PAROS, 3596 ton British steamship requisitioned by the Admiralty and bringing wheat from Karachi to Manchester (NPRN 274828); http://www.coflein.gov.uk/en/site/274828/details/PAROS/
  
  
• REPEAT, a British steam trawler owned by R. J. Tripp of Kessingland, Suffolk (NPRN 274831); http://www.coflein.gov.uk/en/site/274831/details/REPEAT/
  
  
• THE QUEEN, 557 ton British steamship carrying coal from Ayr to Devonport (NPRN 274832); http://www.coflein.gov.uk/en/site/274832/details/THE+QUEEN/
  
  
• THORNFIELD, 488 ton British steamship belonging to Liverpool and on passage from London to Peel, Isle of Man (NPRN 273139); http://www.coflein.gov.uk/en/site/273139/details/THORNFIELD/ . 

THE QUEEN - built on the Clyde in 1897 by Ailsa Shipbuilding Company and owned by John Hay & Sons, Glagsow. The steamship was sunk by the guns of U38.

The ISIDORO was the first Spanish-owned vessel sunk by a German submarine and the loss brought protest from the Spanish government. Germany had come under strong pressure from America, after the sinking of the LUSITANIA on 7 May 1915, to modify its whole submarine campaign, with a promise that liners would not be sunk if engaged in no hostile act. The sinking of the ISIDORO alienated another neutral nation.

With the whole political situation so delicate, the German Admiralty despatched secret orders for submarines to confine themselves to ‘cruiser warfare’; i.e. submarines were to surface to search for merchant ships and ensure that crews were in a place of safety before sinking the ship, unless the ship had shown ‘persistent refusal to stop ... or active resistance to visit or search’.

However, U38 continued southwards after the 17 August, to join U24 and U27 in the Western approaches. These three submarines continued to sink ships between southern Ireland and Ushant on the French coast, bringing the total losses for the year to a peak in this month (121 ships sunk and five damaged). Each event a tragedy for the crews and shipowners concerned.

Today, we commemorate the lives lost by the sinking of the GLENBY in Welsh waters:

C. Neilson, Boatswain, age 21

Ernest Hall, Donkeyman*.

Remembering those who gave their lives for their country and who have no grave but the sea.

*Note: the duties performed by a Donkeyman could be different on every ship, but generally they were responsible for the operation and maintenance of assorted ship’s machinery, other than the main engines, particularly smaller steam boilers and donkey engines used on deck for anchor windlasses and bilge pumps.
