A little bit of local.

On Friday, I was reading a book about childhood experiences in Swansea during the war. This morning, I was sliding and slipping in mud in Dunvant. There’s a link.

I’ve been researching Swansea during WW2 as a result of some of the stories my mum told me of the bombing, the anti-aircraft guns and the Americans stationed here just before D-Day. I found a book in the local library and read with some interest the first mention of anti-invasion defences in Swansea Bay that I’d ever see. The bay would have been an ideal landing place for enemy troops if it wasn’t for the long journey they would have to make down the Bristol Channel. But Swansea had a big port, an airfield near by and a sheltered bay and it may well have been worth the risk. In fact, Swansea Bay was used (along with other beaches on Gower) to practice beach landings prior to the Normandy landings.

My interest has been in finding any evidence of other defensive plans. One of the threats to Britain during the early part of the war was invasion from the west. It was thought that the Germans would make a pact with neutral Eire and come across to West Wales. Lines of fortifications, known as Command Stop Lines were built all over Britain and there is one stretching north from Pembrey to New Quay that would have been used to delay or block any advance eastwards. I had explored parts of this line north of Carmarthen, on one occasion finding myself at the end of a shotgun when I accidentally strayed on to private land. Fortunately, after explaining to the landowner why I was there and pointing out that there were no fences or signs, he let me explore the particular pill box and told me of several more relics of the war hidden from the road.

This stop line reaches the south coast at RAF Pembrey, which is now a bombing range and private airport. There are remains of pillboxes and anti-tank defences near the estuary and they merge into the defences of the airfield itself, and the fortifications and minefields that protected Cefn Sidan and the Pembrey munitions factory.

Swansea had it’s own defences. With the port, bay and airfield in close proximity, and reasonably good transport links, it needed it’s own protection. The beach had several pill boxes and minefields along it’s length and on the low tide mark, iron girders set in concrete were ready to rip the hulls of craft trying to land. There is a suggestion that flame weapons (either oil to be poured on the water or fougasse firebombs) were available, too. Inland, there were anti landing trenches on the hills north of Morriston, anti-aircraft sites on Mumbles Hill and around Kilvey Hill and decoy bombing targets north of the docks.

I found several pillboxes on the Swansea to Llanelli railway line, now disused, that used to run through Clyne Valley. One overlooks the main road through Killay to Gower. Two more protect a bridge over the railway line some 200 yards further south. I would have expected more but I could find none. The book I read said that there were two more pillboxes at the entrance to the Clyne Valley where it meets the sea at Blackpill. Anti Tank blocks also shielded access to the railway and some parts of an old wall made of wartime concrete (with more aggregate as it was cheaper and quicker to make) line the sea front near by. Much of the land between Blackpill and Killay is marshy and undulating and would have needed little extra protection.

Further north at the Loughor Estuary, there is a line of concrete anti-tank blocks stretching out into the water. They are covered by a gun emplacement near the Chinese restaurant, and the estuary also had artillery as it was at one end of a firing range. When you look at a map, the railway cutting (it’s mostly below ground level) makes an ideal obstacle for tanks and runs across Gower. To be most effective, extra fortification at weak points would be necessary. Infantry trenches would be hard to spot after so long as the ground is wet and overgrown. I expected there to be more pillboxes but knew of none between the estuary and Killay.

I went online to see if I could find more about the Clyne pillboxes and found a reference to Dunvant Brickworks. Dunvant lies north of Killay along the same railway line and an archaeological survey had been done in 2009, showing the site of several small scale collieries and a brickworks. The survey also described two more pillboxes and a spigot mortar site in the area and mentioned the ‘Gower Stop Line’. Suddenly it was all making a bit more sense.

And so this morning, I was scrabbling about in the mud in completely the wrong place trying to find one of the pillboxes. I slipped, skidded, squelched and was nearly tripped up by brambles. I climbed, descended and all the while got wet in the drizzle. But it was all worth it (for me, anyway) as I finally came across the pillbox I was looking for. It was high up overlooking the railway line. And even better, it was an unusual design that was used mainly for observation. It was hard to visualise the context as in the nearly 80 years since it was built, trees and bushes have grown around it obscuring it’s original field of fire. It was impossible to enter as bars had been placed in the entrance tunnel. I later found out that it has become a home for bats so I’m glad I didn’t try to disturb it.

For the pillbox geeks, it was a type 22, modified with a longer entrance tunnel and no embrasures or a roof. This one had railway sleepers over the top to provide shelter for the bats.

Mumbles

For most people in Swansea, Mumbles head, with it’s lighthouse and distinctive twin tidal islands, is iconic. It can be seen from the whole 5 mile sweep of Swansea Bay and, by design, it’s lighthouse is visible much further away. I’ve written about it before, here.

The first lighthouse was built there in the late 18th century. It had two coal fired lights in open braziers. The island just out into the Bristol Channel and catches every last whisper of wind; keeping an exposed coal fire burning in those conditions was well nigh impossible. So it wasn’t long before the coal fires were replaced by enclosed oil lamps with reflectors to improve visibility. There was a house on the outermost island for the keeper to live in during his (or her – there were wives and daughters here sometimes) duty, which must have been a lonely existence.

Meanwhile, Napoleon was causing mayhem in Europe and to protect the country, coastal forts were built at strategic points. By this time, Swansea was an industrial centre producing copper and other metals and exporting coal. Copper was particularly important strategically as copper coated hulls allowed Nelson’s ships to move more quickly and maneuver more easily. Mumbles Head was the ideal place for a defences and in the early part of the 19th century a stone fort was built which still stands today. Over the years various guns were placed here. Initially, 6lb cannon protected the port and these were replaced by bigger calibres until 68lb cannon with a range of 5 miles were sited on the island.

Eventually, modern 4.7″ guns were emplaced on the island and the 68lb cannon were unceremoniously dumped into the sea. One was recovered in the 70s and is situated in Swansea Marina. During WW2, these guns formed the inspection battery part of the defences of the port of Swansea, which was one of the biggest Bristol Channel ports during the war. Their responsibility was to enforce the requirement for all shipping to stop and be identified before proceeding into the docks and they were manned by regulars of the 299th Coastal Defence Battery, with Home Guard units and women of the Women’s Royal Naval Service (WRENS).

A pair of 6″ guns formed the defence part of the battery and were sited further back on the mainland, above the Bracelet Bay car park. These heavier guns with their longer range and better visibility would have engaged any enemy shipping trying to enter the bay. Search lights and local defences completed the battery. Further back on Mumbles hill was the 623rd Heavy Anti-Aircraft battery comprising 4 x 5.5″ guns sited to engage enemy aircraft flying in to bomb Swansea.

The whole area was defended from attack by Territorial and Home Guard units in trenches, machine gun emplacements and pill boxes. A mobile 75mm gun was also available to be used where required and there were minefields laid for further protection.

Where Bracelet Bay car park is now were the Nissen huts and other temporary accommodation for the garrison troops. Immediately after the war, these were used for homeless refugees while new houses was built to replace those destroyed in the bombing of Swansea earlier in the war.

The islands are accessible at low tide. A concrete walkway built to improve access for the battery garrison was destroyed after the war when it was found to affect the way the tide interacted with the beach. As you walk out, you can see the remains of the walkway along with railway lines and, as you near the outer island, posts for guide railings. On the outer island, the Napoleonic fort forms part of the current lighthouse structure. Around it there are the remains of the buildings that made up the more modern defences. And engine room to provide power for the searchlights; barracks for the garrison; platforms for the defence of the island from landward attack and the two search light houses.
