Dan Snow's History Hit - Churchill's Secret Army

Episode Date: April 20, 2026

Trap doors under toilets, hidden radio rooms in the back of wardrobes, secret bases behind waterfalls....Dan investigates an extraordinary network of secret resistance cells set up during Britain's "darkest hour".In the summer of 1940, Britain and its empire stood alone as the Nazi war machine stormed through Europe. Prime Minister Winston Churchill created something extraordinary: secret factions of men and women trained to wreak havoc behind the lines of an invading army.Dan once again joins forces with Andy Chatterton from the Coleshill Auxiliary Research Team, who are unearthing this incredible part of World War Two for another bunker hunt. What they find on this adventure is truly extraordinary.You can learn more about Britain's secret resistance in Andy's book 'Fortress Britain 1940: Britain's Unsung and Secret Defences on Land, Sea and in the Air'.With thanks to Chris Hale, Nina, Will and Martyn from CART, Andy Aust and Duncan Akers.Produced by Mariana Des Forges and edited by Dougal Patmore.You can watch our video documentary on Churchill's Secret Army!

Now, if you're a long-time listener to this podcast and why wouldn't you be, you may remember that back in the summer of 2023, my producer, Yanna and I went in search of hidden World War II bunkers in the new forest near where I live. These bunkers are so excited.

They were set up in preparation for a German invasion. So local British men would hide down those bunkers. Once that invasion had taken, place, they would lie in wait for the Germans, they would then emerge at night and carry out acts of, well, ambush and sabotage and assassination to try and disrupt that German invasion. They were called auxiliary units, and the men who served in them were Britain's unassuming silent assassins. And in the vast majority of cases, they took the secret of that service to their grave. And that meant they also took the secret of the location of most of these bunkers their graves.

So now hundreds of those bunkers lie hidden along Britain's coastlines, particularly here in the south. It's difficult to say how many of them still exist. No maps ever made marking the location. As I said, the exilaries were sworn to total secrecy. So it's only now, 80 years later, as people, well, literally stumble across, sometimes fall into these bunkers as they cave in that we can build a better picture of Britain's deadly defensive network. A year and a half ago, we were scouring the new forest. We got that tantalising tip-off that a local man said he'd come across one of these bunkers as a child where he was playing with his friends in the forest.

But we made only a very minor discovery. So listen, I accept that single wire. May not have been the most exciting thing in the world. Well, friends, there's been a development in the story. As that podcast came out, we have received another tip-off, news of another bunker that's been discovered way down in the southwest. So that's where I've come now. I'm just walking along that coast. You hear the waves crashing the pebbles beneath my feet. I can't tell exactly why I am, sadly, because we're going to keep this location a secret. But the history hit team has assembled, and we're on the way there now.

And what makes this mission so particularly special is that we're going to be joined by most probably the last surviving member of any auxiliary unit, Ken Welch. And by extraordinary coincidence, Ken served in this bunker as a teenager with his dad. He too was sworn to absolute secrecy, and he never told a soul about it until the last couple of years. He's now 98 years old, and he's going to be joining me as we go in search of his former bunker, which he has not been back to for 80 years since the war. Of course, our guide is the brilliant historian, Andy Chatterton, who's an expert on British wartime resistance.

If you're new to this podcast or you need a refresher, then don't worry. We're going to cover the history of the auxiliary units again, and we're going to be giving you the lowdown on Hitler's planned invasion of Britain. As you join us for another history hit bunker hunt. In the summer of 1940, the balance of the Second World War was firmly in Hitler's favour. In less than a year, the European Order had been dismantled. Poland had been crushed in weeks. Denmark and Norway followed in the spring. Then came the biggest blow of all, the fall of France in June 1940.

What made it so stunning wasn't just a victory, but how fast did it happen? German forces used what is commonly known as Blitzkrie, an innovative form of lightning warfare, combining tanks, aircraft, artillery, infantry, radios and speed. The supposedly impregnable defence of the Maginot Line were bypassed, and in just six weeks, mighty France had been humbled. Meanwhile, the British Expeditionary Force fighting alongside the French had barely escaped from Europe during the Dunkirk evacuation. It was a miracle of survival, but it couldn't disguise a strategic disaster.

Britain's army had been humiliated, most of its heavy equipment had been lost. It seemed very possible that a German invasion of Britain was imminent. All right, Andy, summer of 1940. The big headline is shocking, mind-blowing collapse of Allied forces in Western Europe. The Brits, the French, totally defeated in the Battle of France. That came as a surprise. Yeah, a massive surprise. If you think at start of the Second World War, the French army is the largest and most mechanised

army in the world. And they've just been beaten in six weeks. Destroyed. And we can look back in hindsight and say whatever we like about the German invasion. or the likelihood of German invasion of Britain. But at that point, it was an absolute shock. And the German army seemed unstoppable. And had the British government made any plans

for defending the home islands before that disaster? Yes, it had started. In the years kind of running up to the Second World War, there was a slight ponderance around actually is attack the best form of defence. So large amounts of battalions went out to France because that was the feeling that actually the attack is the best form of defence.

But that's not to say that regulars weren't still in Britain. And after the fall of France, basically with all our mobility, basically left on the beaches, or most of it. All the tanks and vehicles and trucks, everything's just left in front. Exactly right. Suddenly, we have to think about how do we defend Britain

without such mobility. So General Ironside, the C&C of Home Forces, constructed in a matter of weeks, this whole, that we still see in our landscape today, pillboxes and stop lines, anti-tank teeth and anti-tank ditches, just huge amounts of concrete that have come into our landscape. In fact, Andy, I mean, this is almost like it was planned, but we are now about 30 metres due south of a concrete pillbox.

Yeah, there it is. It's overgrown, it looks like it's in someone's private garden, it's overgrown with ivy and it's got long grass growing on the roof. But yeah, that is not an uncommon feature of people listening to this abroad. It's quite normal to see that along, particularly the British South and East coasts, like where we are now. Devon, this beach's been pretty good for Amphibb. Yeah, it would have been. Would have been.

Perfect, perfect beach. And actually, when we see pillboxes like that one, I think it in many ways kind of reinforces our perception of Britain at that time. It's isolated concrete boxes that look a bit rubbish, if I'm being honest. Yeah. Yeah. German Armoured Division lands here.

I don't know how long that's. Yeah, well, exactly, exactly. But seeing it in a wartime setting, seeing it connected up with the other peal boxes in the area, seeing the slit trenches around it, seeing the fact that it's camouflaged, and seeing the fact that it's part of a stopline that's pushing the invading German army

in the direction we want them to go means that then we can use the limited mobility that we've got much more effectively. The Germans will always go with the least path of the resistance. So by pushing them around the pillboxes, by pushing them around the tiger's teeth, we can much better utilize the limited amounts of tanks and vehicles we have to more effectively counter-attack.

Right, so actually the government's and the military have really got a grip on this. They're playing for the Germans landing on these shores, what to do. Gosh, there's a plan, which is fight them here on the beaches, but then if they do get inland to sort of funnel them, channel them into places where you can ambush them, kill them, use the high ground. Exactly right, exactly right. And Einstein at the time got a large amount of criticism and continues today.

But actually, I think he was utilising the resources he had at that point really well, really well. And it's almost like an Iron Age hill fort where the defensive channel the attackers in the direction. and where you want them to go, and therefore you know where they're going up, and therefore you can attack them in the place you're happy to. And a bit like the trench warfare, that generation of officers would have known so well. You use the barbed wire. You leave sort of gaps here and there, and then they're very well covered with artillery and mortars and machine guns. So it can create killing zones.

Exactly right. Exactly right. So that, yeah, as you say, the whole of the south is covered in these concrete boxes, which, as I said, look, pretty rubbish, but actually it would have been a really effective way of stopping them. Andy, that's what's going on here in Britain. What's going on just over there on the other side of the channel? what preparations is Hitler making?

It's an interesting question because the fall of France has happened. Germany is uproarously happy. It's gone far better than they could ever, ever have expected. And then suddenly they have this challenge of the channel, of the moats that we've got. And Hitler's plan isn't just one plan, and this is the trouble. He asked the Navy, the Air Force and the army to come up with their own separate plans. Each one is slightly contradictory to the other. Goring's ultimately confident that he can destroy the Royal Air Force

to give the mayor superiority. He doesn't think that's going to be a problem. He's kind of seen the Battle of France, and to an extent the REF did struggle and the effectiveness of the Stuka, the dive bomber plane. I mean, Guring's a confident guy anyway, right? But now, after France, he is super confident. He didn't think the RIF stands a chance.

So the Air Force are telling Hitler, we don't even need to evade. We're going to knock the RIF out, then we're going to bomb Britain to its knees. They'll have to make peace. Exactly right. But the army and the navy, what are they up to? Well, the Navy wants quite a narrow invasion period because they realise that the Royal Navy is the largest and strongest Navy in the world. And so they want a narrow window to operate in.

The army wants a wide window to operate in because they don't want to be stuck in a narrow zone where the British Army can concentrate the counter-attack. So immediately there's a real issue with the invasion plans because everyone has different objectives, have different plans and it goes for Hitler's whole approach throughout the war is to not give one general or one armed force the superiority and that's exactly demonstrated in his plans for the invasion. So the navy wait for a day like this we're on this beach it's a beautiful day the sun's out the sea is flat.

So the navy you want to kind of dash across on a narrow front and just try and land as may troops they can before the Royal Navy comes. That's exactly right. Yeah. But the army I guess they what so they want to land keep the British guessing they want to want to land anywhere from the Isle of Wight to Dover. Exactly. Wow, OK. Exactly. Because they're more dispersed, and they know where they're coming, and we don't. The British don't know where they're coming.

So we're going to have to disperse our limited reserves. And we got 300,000-odd troops back from Dunkirk, but they're still recovering, frankly. And the whole of the German military force is incredibly confident this could happen, perhaps apart from the Navy who see the reality of what the Royal Navy is capable of. So Hitler's invasion plans fraught with different. faculties and contradictions right from the beginning. Yeah, and they were getting in thousands of river barges that were going to transport the troops across,

either to be tugged across or with their own engine. And, you know, if you're in a flat-bossom river barge going across the channel, it's sick people can think about a sort of canal boat almost. Yes, exactly right. It's absolutely bonkers. It's absolutely bonkers. It's all right. Ironically, it'll be right in the day like this.

It would be. Not many of these days on the channel. No, they're not. There are not. So that's why the Battle of Britain matters, because if you're going to take all these canal boats, these barges, across the channel in the teeth of opposition by the Royal Navy, you need to have total control of the air

so your planes can help your fragile naval forces to beat off the British. Exactly right. You're already at a disadvantage, you don't need your enemy to have superiority in the air as well. And so winning superiority in air is a necessary precondition for any its invasion stuff. It absolutely is because we saw in Dunkirk, actually hitting boats from the air is quite difficult, but if you're trunding along in a barge and you see a British plane over there, you know you're pretty much done for.

So, yeah, absolutely. Air superiority is a must. But Goering's supremely confident that's going to happen. And that's the point about the Battle of Britain. Britain defeats that German attempt to win control the skies. So that's why the invasion could never take place, because they haven't got that preconditioned. That's exactly right.

And frankly, the German Navy was never really very confident that it was achievable anyway. So it's very easy for us to look back in hindsight and say, Operation Sea Line was a complete washout. It was never going to work. At the time, the German army had just sped through Europe. They seemed capable of anything. So all the defences we put in place, all the thinking that we had to do,

the bravery of the airmen, the bravery of the guys in the pillboxes around us, it shouldn't be misunderstood. The German army had just sped through Western Europe and they looked unstoppable. So we had to prepare for the worst outcome. There's such a powerful perception that Britain, in those early days of World War II was ill-prepared for an invasion. We imagine that protecting Britain's coastlines was a bumbling army of part-timers, a dad's army, manning a handful of little concrete boxes. But that's simply not the reality. By mid-1940, a formidable nationwide resistance network was

already in place. Within that network was an important organisation called. called the auxiliary units. Thousands of men, ready to take to secret underground bunkers in the event of an invasion, ready to emerge and sabotage the enemy advance. This was Churchill's secret army. So Andy, what are these bunkers that we're looking for?

They are being used by this group called the auxiliary units, whose role is to disappear to these bunkers as soon as the Germans come into their area, leave their families who have no idea what they're up to, and disappear at these bunkers and then come out at night and disrupt the supply chain. This isn't about taking on the German army

face to face. This is about causing as much chaos at night to slow down that German advance. Sabotage, assassination, ambush. Exactly. All of those things. Anything that's going to take the Germans to take a step backwards, to pause to allow our regular troops

to have more time to recover and counterattack. Is this a pre-war thing or is it suddenly getting stood up in a bit of a panic as Britain faced invasion in the summer of 1940? It has its roots in pre-war. It has its roots in pre-war. in two pre-war organisations, one set up by MI6, one set up by the British military.

By kind of May, just around Dunkirk, it's kind of up and running and being recruited very, very quickly across the countries in these kind of key vulnerable counties. That German invasion doesn't come, but this organisation remains. They continue, what, they're training and preparing? Yeah, training locally, obviously training to gain access to the targets that they would try and hit as the Germans came through. They used the British Army as practice, which the regular troops did not enjoy because they were so often shown up as not being very good at guarding airfields or country houses. And also train at the auxiliary unit's headquarters and a place called Colts Hill House up near Highworth near Swindon.

And there they were going to go and train for a weekend. Again, not being able to tell their wives and family where they're going. But nonetheless, go up there, train and learn everything they need to know. So going across fields at night, where to place explosives on German tanks and planes, how to take out a century. silently with a knife, all the stuff that you need to know to be effective. And these are men who are still doing their day jobs. Yeah, absolutely, and quite tough day jobs. I mean, lots of them are farmers and quarrymen and miners.

So during the day, just carrying on as normal. And then at night and weekends, training to a really high standard in terms of their kind of guerrilla tabitur roles. And they would live their normal lives right up until the point the Germans entered their town. So if we're in Devon, for example, and the German invasion is taking place in the southeast, the guys in Devon would not become operation. until the Germans are almost on the boundary of their town or village.

Nobody could know. Nobody could know, not their closest family and friends. And anyone who did happen to come across their operational base or asked too many questions would have to be added to a list of people that have to be assassinated as soon as the Germans came in. Because their window of operation is so short, it's perceived to be around two weeks,

they had enough rations for two weeks, that anything that had the potential to shorten that time they had to deal with immediately. So it sounds over. brutal, but actually, you know, looking at that bigger picture, if Britain had fallen, that's essentially it. A lot of the auxiliary unit members we've spoken to over the years kind of understood that bigger picture, that the sacrifice that they would have to make, their communities unknowingly would have to make, would have been worth it for the bigger picture.

It's estimated that there were up to 500 auxiliary units along Britain's coastal counties, hiding in plain sight in tight-knit communities. As I mentioned earlier, the only known living survivor of an auxiliary unit is a man named Ken Welch. He's down in Cornwall. And as part of our mission to find a bunker that still resembles a bunker, we're taking Ken. We're going to try and find the one he was stationed at with his father 80 years ago. One that he hasn't been back to since. Hello. Hello. Now, you can't be Ken. I'm Ken. You don't look old enough. No, I'm not. What are you talking about? Oh, exactly. You look 25. Nice to meet you. I'm dad.

Let me take my shoes off. Oh, you don't have to do that. Well, we... Are you sure? Okay, yeah, we... All right. Please didn't even offer. Ken, you were a young boy, do you remember the war starting? Yes, I do.

I was sitting on a chair in my grandmother's kitchen. I think it was a Sunday morning, and at 11 o'clock, and I heard the Chamberlain declare war with Germany. And talk to me about your dad, because he did a job that you probably didn't know about initially. Oh, yes. He worked in a quarry taking out big lumps of granite for making monuments and stuff like that. And then the war came along and somehow he got into this auxiliary unit business. You didn't know about that? No, I didn't know what was happening.

So he would go to work all day. Yes. But he'd be off during the night doing his... You didn't know what he was doing. No, I didn't know where he was going. All I knew was he would come home with a Tommy gun and bits and pieces like that. I was 16 then, but I was only a month off 17.

So I said to him a bit, why can I have a go with that? So they arranged for me to join. I put my age on for a year. So your dad let you join the unit? Yes, he let me join, yes, yes. I suppose you thought he could take care of me somehow. But you must have been an exceptional teenager

because they didn't want any old kid hanging around with them. Well, I was full of life. very interested in stuff like that. And did you know what you were joined? Do you think, well, here, I'm just joining the Home Guard. I'll just go and sign up. I knew it wasn't the Home Guard proper, but I just thought I was joining a kind of Home Guard,

a secret sort of thing, which I was very excited about. But I never considered the consequences if we were invaded. What happened was, if we were invaded, we would go to the operation base. We had a fortnight's supplies there, stuff like that. And we would go out at night, we wouldn't go out during the day, we'd go out at night and do as much damage as possible. We would have had made Penryn Viaduct unusable in case we were invaded, you know, that sort of stuff. We had to do as much damage to delay the enemy as possible.

So you're a member of this crew and you did the training. You had to explode demolition, explosives. Yeah, that's right. Assassination, what was small arms? Yes, they, we used to go to Swindon for. for training for a weekend once in a while. I went up to Swindon. I remember going up, it was in November time,

and it was very cold. And we were in these big half-rimmed huts, and there was two tortoise fires in them. When we got their one each end, both red-ought, they were, I remember. And we had our meals with the officers. They were treated like officers. And we went out, training in at night,

crawling around the fields. We had a bit of fun up there. Was it fun being alongside your dad? Yes, we got on very well, father and I. And what about the secrecy? Did you have to discuss killing people if they found out where the base was and things like that? We had to sign a secret document, you know,

to swear a secrecy. There was a cottage. A couple of people lived in the cottage that could see, and not the entrance, but the gateway to where our OB was. And of course they would see us going in and out every Saturday or Sunday. And of course, if we were invaded, then the Germans would get older them and torture them to find out what they knew. So if we were invaded, somebody would have had to have gone and said goodbye to those.

They would add to have been shot, I'm afraid. A terrible situation. I don't know who would have done it. They might have drawn straws to find the one that would go and do it. So those are the kind of conversations you were having, planning for the invasion, right down to killing this old couple? Yes, well, yes. That's right. And if anything happened, if we were invaded and anything happened to me, if I were injured in any way, then I would have had to have been shot. Because they would have tortured me, questioned me, if I was captured, you see. Wow.

That was a situation. It was a scary situation. I never realized how scary he was. I bet it was more scary for your dad. Yes, yes. Imagine being on the unit where they have to shoot his own son. Yes. That wouldn't have been the situation.

What do you remember of the bunker? I just remember going up there and spending a weekend and stuff like that. Just to see how we got on over for a couple of nights. There was an front entrance, of course. And then there was a way out the back. We had a little lad.

to climb up to go out the back. And after we got out the back, we just have to have to there's nobody out there to see us coming out, but we had to take our chance on out, I suppose. Ken, it's very exciting. We're going to try and find the old bunker today, are we? I think so. Can I see what it is? Surely you'll be like a salmon returning to where it was spawn. You'll have a homing beacon, take me right there. Yes. Yes, it's rather a long time Since I've returned home. And the protical son is why it's concerned, I think. So what, 80 years or something?

Well, yes, it is, I suppose, yes. It was 1994 till now, yeah, that's right. This is Dan Snow's history here. More after this. Andrew Chatterson, what are these bunkers like? They are the most remarkable structures. They are underground. Essentially, they're a bit like a big Anderson shelter,

but a lot more complicated. a lot more cool. So as you're walking along, you will find as an auxiliar a hatch, a hatch of some form that's flushed to the ground, heavily disguised, and the way into the hatch can be done in various forms. So it might be that you stamp on it and it comes up in a counterweight system and swivels around and lets you in. It might be that you pull what looks like a tree route and that will either activate the counterweight system or it'll ring a bell in the bunker and the other guys can let you in. Or you have like different coloured, each member of the patrol has a different coloured marble and then you roll it down what looks like a mouse hole.

goes underground, rattles about in a tin and then they let you in. Don't be silly. Yeah. Yeah. So once you're in, you'll find a ladder going down maybe kind of 12, 15 feet into a shaft, almost like a chimney. Go down to the bottom. Quite often you're confronted at the bottom with a blast wall. So that's there to, if the Germans happen to get into the hatch and dropped a grenade down, it protects the main chamber from the blast. You weave your way around the blast wall and then you're into the main chamber. So the main chamber is where the guys would have been during the day, bunk's there to sleep, tables, food equipment. Occasionally there's a kitchen, which isn't ideal for kind of keeping secret.

So they would funnel the chimney up a hollow tree and the smoke would disperse at the top of the tree line so it wouldn't kind of go through the forest to give the Germans a clue. There's quite often a pretty horrific Elson chemical toilet, which after two weeks of nervous men constantly using it would be pretty grim. They used to store their explosives mainly away from the place that you're staying in, which that's just good thinking. So they've been an explosives store just down the road a little bit. And then into an escape tunnel, which can lead 60 to 100 foot away, that often goes into a water source to kind of aid in your escape. But essentially, most of the patrols knew that if the Germans were at your entry hatch, you're

pretty much done for. So some didn't even bother with an escape tunnel at all. So how do you even go about looking for these needles in a haystack? Are they all over the UK? They are almost exclusively in coastal county. So if you think from the York and East at the top of Britain, kind of down the north-east coast, yeah, east coast. Yeah, east coast. south-east corner, south coast, south-west and south Wales. There's not much on the west side of the UK because they didn't see there's a perceived threat from the Irish side. And they're set in from the coast a bit? They tend to be set in kind of five to six miles inland because they don't want to be caught up in any initial wave of invasion. And then they're in areas where there's a key target as well.

So it might be near a key road or a key bridge or near an airfield that Lufufe might take over, a key manor house that the Germans might take as a local HQ. In some cases near the house of a prominent member of the British Union of fascists, who would have been seen as a collaborator, and would have been assassinated immediately as well. So tend to be five to six miles inland, near key targets, incredibly well disguised. So have you developed a bit of a nose for it? Do you just walk across a landscape and think, oh, I reckon there should be one around? You do, you do get a weird feel for it because you kind of see, well, actually, that's a good escape route down there, there's a river down there, there's a good target there, you do get a feel

for it. And what we do have is that in about 1943, a list of all of those who are currently serving the auxiliary units in 43 were put together with their addresses. So as researchers, all we have to play with is, well, actually these guys all seem to live near each other. That's probably one patrol. Then you look at, well, actually, there's a good target there. Oh, and there's a forest there. That's likely where the OB is. You know, if it's intact, you could be walking around that forest for weeks about finding it. But yeah, it's a, it'd be too easier. Well, you and I've got previous there, buddy, tearing around the neat forest. We arrive on top of a tree-covered bank, overlooking

old quarry. Among the scrub is a square manhole like one that you'd find in the street. But going down through the rock, once you look inside, you see a vertical tunnel with a rudimentary ladder fixed into the wall, just as Ken said. Ken, how are you feeling? Well, not too bad at all. Whoever discovered this place again must have had some hell of a job. Getting into it. It goes down into an open chamber cut into the granite. It's not exactly an easy way in for an older gentleman, but lucky a better route has been found by the local historians Chris Hale and Gareth Wynne,

who recently rediscovered this bunker and have joined us on this expedition. Ken, do you want an arm up this slope? Do you want an arm? I can hang on to this. Okay, okay, let's do it. All right, let's come on up. We go round the bank and are faced with a muddy incline that goes up to a small hole in the side of the rock face. What do you think, Andy? Feel good?

Feels good. Well, I can see Wiggly Tin already, which is a good sign. Always a good sign. You truly have no idea anything of note was here if you weren't already in the know. We're coming to something up here. We make our way up cautiously with Ken, climbing over fallen trees and jutting out roots. Have a rest there, Ken, and see you. Just have a pause there. Yes, thank you.

What do you make of this here? Yes. I see you remember that. That doorway looked bigger than it is. Yeah. So we think this was probably the escape tunnel. So we think it's out that way. It was out the other end.

Do you think? What's it like being back here after 80 years, Ken? Surprise? Yeah, I'm surprised. Didn't think I'd ever see this again. When was the last time you came? What did you think? October, November 44? Something like that?

Yeah. The Second World War was still raging when you were last here. Yes. Cricy. What do you think? Should we try and get inside, Ken? Yeah, have a go. Eventually, we make it inside.

That's it, what's your head? Wow. What do you think of this place then? Does it look familiar? This is here. So what was in this section here? Was this where the beds were? Yeah, I remember.

I thought it was wider than this, but it isn't. I think they did, um, made tea and stuff back there on the steps. Was that right? Was that tea-making facilities? Critical. Yeah, I had a cup of tea. I was much able to stand up easier than I can now. So from here, you would have been a base here for a fortnight,

and you would be going out every night. I can't believe that it would be seven to eight men cramped in here. Seven. Seven men. Cramped in here is... It's not a lot of space, is there? So, Ken, so you would come in and in here in 43, 44, what would we have seen in this structure?

Would we have seen bunks either side? Yeah, of course we would have seen. some bunks on it on each side. I think it was three, three bunks, I think, all the way down down to the bottom. Never had much room in the middle, as far as I can remember. No. Like I said, we used to have a cup of tea,

but used to make them on the steps, I think. Right. Yeah. And a primer stove, you know, in those days. Yeah. Never had the modern ones like today. No. And what was the lighting?

What did you use for lighting? Candles. Candles. Just candles. And would you leave weapons in here? Our weapons, they took our weapons home. Oh, you took them home? Yeah.

The explosives and stuff were stored here. You kept all the explosives here? Yeah, I think it was down there at the entrance, just as you come in, in there and that space. Oh, there, yeah. I think. It's been very relaxing, sleeping with your head next to all those explosives. Yes. With candles about, yeah?

Smoking. So how is this different to other ones you've been to? Well, this is slightly different because they've made use of the quarry surroundings. and obviously quite a few of them worked in the quarry, so we're quite used to handle explosives and digging out, and this is what this one really is. Usually they're in a forest or a copse and something like that, so this is a little bit different.

But it does give you that impression of just how grim it would have been seven men in here for a fortnight under real pressure, in here during the day, no real light, just really, really grim stuff. Yeah, I mean, yesterday it poured with rain, as a result, in here, it's pretty damp today, so it would have been grim potentially. Really, really grim, yeah, absolutely.

And yeah, imagine trying to get some sleep. And it's so important for them to get sleep during the day because you're coming out every night to go on a mission, to go and blow up a convoy, to go and assassinate someone. So you needed that rest, but gaining rest in here must have been really difficult. Imagine if the enemy had invaded.

Oh, my God. And this would have been your home for two weeks. For two weeks? Yeah, or longer if you live long enough. Our life expectancy was two weeks. Because your window of operation was so small, expected to be so small just a fortnight. You had to go out every night

to go and destroy something, to go and cause havoc. If the Germans came to Mabe, you and your dad would have disappeared, you would have come here, and your mum wouldn't have any clue where you've gone or what you're up to. No.

She never knew. I don't think she knew the day she died. Wow. Or even when she died, I don't think she knew. And you're a teenager? Yes, I was a teenager. 17, 17 years old. It must have been fun being with your dad.

Oh. I'd like to be with my son. Yes, I was much. He was good. He took care of me, no doubt, about that. Wherever he went, he took me with him, like, you know. If he went out on exercise, crawling around the fields, I'd be with him. And you must have been proud to be with your dad.

Oh, I was quite happy, yes. Enjoyed it. Really enjoyed it in those days. My goodness me. Thank you for bringing me here, 1984, 80 years. There's something extraordinary about bringing someone back to a place like this. you can see it in their face the moment the memories come back. 80 years is a lifetime, and yet the bunker is still here, almost untouched really.

For us, it's amazing to step inside a proper exerie bunker, the kind we'd have been so desperate to find on our last venture into this story. It really brought to life what it would have been like to be cramped inside, waiting for the sounds of the enemy overhead. But the auxiliary units were only one piece of a much bigger web of resistance, all ready to spring into action in the face of an invasion. Through his groundbreaking research, Andy has recently discovered that there was yet another secret resistance faction,

one ready to go even further, had Britain been conquered by the Germans. So we researched the auxiliary units, which we know were very much on the coastal counties, on the vulnerable counties to invasion. But for years and years, we were getting information from all parts of the country saying, oh, my granddad or my grandmother was definitely in New York's units. They were trained in unarmed combat.

They were trained in explosives. They had hideouts where they were to come out and blow up German infrastructure. But this was coming from Leicestershire and Nottingham and Liverpool and all over the country, where we know absolutely there were no auctions, which was confusing to say the least. And then in 2010, the official history of MI6 came out by a chap called Keith. Jeffrey. And in that book, there are about three paragraphs, unreferenced, about Section 7. Now, Section 7 is a MI6, a SIS group that was there purely as a post-occupation resistance. So after Britain had been defeated militarily, this group would have become active. And it's MI6,

i.e. the foreign secret service rather than MI5, because of what they were doing in mainland Europe. They were taking what they'd learned in mainland Europe and implementing it in the UK. And it was so secret this group that MI6 didn't tell MI5. They weren't very keen on the military knowing. And so all the members that they recruited, all signed official secrets accent, as we'll go into, we know less than 20.

But has the potential, because this isn't just the coastal counties, it is the coastal counties, plus all of England, certainly, Wales, that's a huge amount of people potentially involved, possibly tens of thousands of people who signed official secrets accent,

almost all of them went to the grave without telling it anyone, anything. Who are the ones that you have managed talk to, and have they been willing to finally break their silence? Yeah, so it's really interesting. So from the Keith Jeffrey official history thing, we know that there were three guys in SIS, MI6, who were kind of leading this. It was a chap called Valentine Vivian, who was head of Section 5, which was counter espionage. There was a chap called Richard Gambier-Parry, who was part of Section 8, which was the communications, so the wireless part of SIS, and also a really mysterious guy

called David Boyle, who was head of or passed of Section N, which was something to do with diplomatic mail. But these guys were in charge of the recruitment and training and the establishment of this resistance group. And they went around the country. So they started in six counties in July 1940 in Norfolk, Suffolk, Sussex, Somerset, Colmore and Devon, where they did a trial of these wireless sets and they proved to be really successful. And then they recruited everywhere in the country. It's hard to imagine just how wide this network was. For example, we've got a chap who came forward in the early 2000s called Peter Atwater. Peter is a really good example of the type of people or children that SIS were recruiting for Section 7. Peter was 14 when he was recruited for Section 7.

He was an ARP messenger and he was part of the Air Training Corps as well. And he lived in Matlock in Derbyshire. his role had the Germans occupied Matlock was initially as an observer. He was to walk around Matlock and gather information on the occupying forces. He would then take this back to his cell leader, a chap called Mr. Topliss, who was a draper. At the back of Mr. Topliss's shop was a fake cupboard. You go through the fake cupboard and the back is a room with a wireless set in. There are two female wireless operators called a Mrs. Key. and a Miss Swan. He would then pass this information onto them. They would then radio this information about the occupying forces to either an unoccupied zone. So they thought that Britain would be like

France, they'd be an occupied zone and an unoccupied zone, with Scotland's most likely to be the unoccupied zone, with some kind of Petan Vichy like government in charge there. Or the information, because Richard Gambier-Parry was involved, the information from these wildest sets might have been powerful enough to eventually end up in Canada with some kind of government in exile. So his role was to do this. Incidentally, in the, under the table where the wireless set was, was a grenade with the pin stapled to the table. So if the Germans had somehow found out that this was a resistant cell, broken through and found Ms. Swan and Miss Keyes in the back room, they could have called the grenade very easily, thrown it over their shoulders, grabbed their wireless set and

escaped to carry on. Because this is about long-term resistance. So the auxiliary units and special Ducey's branch had that very set window to disrupt an invasion. This is much more like the French resistance where you can move, you have kind of portable wireless sets and move quickly and keep going for as long as possible. Peter also was responsible for finding a room or a building in which people on the run from the occupying forces could be passed on. So rather like the escape lines in France in occupied Europe where an Allied airman was shot down, If the resistance got hold of him, they would pass him on from house to house to house, from safe house to safe house, to try and get him back to neutral territory from where he can

then make his way back to Britain. It looks like Section 7 were setting up an escape line for enemies of the occupying forces to try and get them out to an unoccupied zone, presumably Scotland or maybe Ireland. So that was being prepared. He had to meet other boys of his same age in Birmingham. I think they met. Each of these chaps were part of the escape line so they knew who to pass them on to. So it looks like it was carrying up through the Midlands and up through North. And when they met, they had to talk or include a word in their conversation to ensure that they weren't being followed or that they weren't under duress. So what better subjects to talk about than the weather. So Peter had to include the word ice

in any conversation he had if he was meeting with one of these guys under occupation. And another thing Peter was said that a bit later on he was taught was how to be a sniper. So a 15-year-old was being taught. And he used some very specific terminology here. He was being taught, he said, by terrifying ex-First World War NCOs, how to be a sniper. Peter was 15. But as a father, that is a terrifying prospect. And his parents had no idea what he was up to.

You listen to Dan Snow's History Inn. Don't give up on us just yet. There's more coming. And it wasn't just young boys, girls as well. Correct. absolutely. And a lot of what Peter said there, you can take with a pinch of salt because it's one guy telling you. But then, as I wrote the book, families from Southampton and Leicestershire were telling me exactly the same stories about their grandfathers, in this case, being taught

by terrifying NCOs using very similar terminology. And then just before I published, a family got in touch whose grandfather William Hughes was a sharpshooter during the First World War. and he said in Liverpool, he was teaching resistors, and he used the word teenagers in unarmed combat and how to be snipers in the tunnels underneath the Mersey. So suddenly, one man's story is then confirmed by multiple other independent stories across the country. But you're right, it wasn't just men and boys being recruited,

and this is a key difference with Section 7 and SIS, that they were actively recruiting women in combat roles and teaching them how to use explosives, how to create Molotov cocktails, how to derail trains, and most importantly, how to become honey traps, how to use the garot. And I know that you've had podcasts here talking about some Dutch women who were famous or infamous for their roles in dispatching German officers and German soldiers, exactly the same as being done here in preparation for an occupation.

So there's a fantastic example. A lady called Jennifer Lockley got in touch with us saying that her mother was in the auxiliary units. We know and that she was from near Leeds. So there's two things there. There's no women in the auxiliary units and there was no auxiliary units in Leeds. So we knew something was going on. So we talked to her about Section 7

and then it seems that on her deathbed, her mother, Irene, called her in and said, I've got something to tell you. Jennifer thought she was going to be told that she was adopted or something. But actually, her mother said that she was part of a secret resistance cell in a village near Leeds.

She was in a cell with her father. her uncle and her two cousins, and they're based in a cave, and she was taught how to use, as I said, Molotov cocktails, how to use the garot, how to derail trains, how to make the occupying forces live, an absolute nightmare. Now, her daughter, Jennifer, thought she might be losing it a bit in her final days. But then when we started talking to her about Section 7, some stories from her childhood started to make sense. So, for example, she remembers in the 50s standing in her hallway as a pots and pans salesman had come to the door and her mother had opened the door and the salesman was quite aggressive in his sales patter and put his foot in the door to stop

Irene shutting it. The next thing that Jennifer remembers is the pots and pans salesman sailing through the air, pots and pans tumbling everywhere because now she can see that her mother had performed like an unarmed combat move on this guy. And that is amazing. I know, I know. And Jennifer's saying it's so out of character for her mother. This memory is just stuck with her because her mother was a, wouldn't say, boot or a goose type of lady. But suddenly this chap was flying through the air. And the whole point of SIS recruiting women

is basically the mistake that the Pots and Pan salesman had made, that he does not suspect a shy, retiring housewife to be able to do that. And that's exactly why they recruited people like Jennifer. They also recruited a lady called Priscilla Ross from Hornchurch. Now, Priscilla said that very similar things to Jennifer and obviously in a very separate part of the country, Horn Church in Essex. She was taught how to make Molotov cocktails, how to derail trains,

how to assassinate German officers. Her base was under a church in Hornchurch with a tombstone that if you moved the top, kind of swiveled over and revealed an entrance underneath the church. So I've been in touch with the church in Hornchurch and had from their perspective a weird conversation about whether they had any moving tombstones in their graveyard, which they did not. But they did say that they just found a space under the church, which they had not known about, and they couldn't find an entrance. So something else was maybe to go and look at. Buddy, we're going, we're going on church. No question about that. So what you're saying is here, there is a network, people still living among us, say, because they were young, they were boys

and girls, who are trained killers, saboteurs, and resistors, and because they never got the The balloon never went up, they never got the call, they just went and lived the rest of their lives and never told a soul. Correct, absolutely. So, for example, Peter Atwater and Matlock knew of two other cells near him in Matlock. So potentially this could be absolutely huge. And they didn't really even know who they were working for. So at the end of the war, Peter was part of the local history society and he told his story and had started to read about the auxiliary units and presumed that's what he was in. And in fact, to the extent that there's the blue plaque above what was the Draper's shop saying this was a auxiliary units radio cell, but it wasn't.

So Peter didn't know what he was in at all. That's how secret is. The people who were in it didn't even know what they're in. And most of them, because they weren't called upon, said absolutely nothing. There's another example from Yorkshire of a mother who passed away fairly recently who was high up in the WI in Yorkshire. She told her family that she was responsible for driving, using the WI as a cover, for driving around Yorkshire. And she used very specific terminology, delivering explosives and weapons to caves all around Yorkshire. So there is, there's so much tantalising information out there. We know relatively, well, very little, essentially, as to the size of this group.

And also what their objectives were, what does success look like for Section 7? Because the resistance in mainland Europe had Britain as a island of hope of a platform from which liberation can come from. If Britain had fallen and we were occupied, it's the year. US going to get involved in the war? If so, the Atlantic Ocean is a big old gap between us and liberation. What does success look like for a ongoing resistance? I'd say it's, and again, very much suicidal, but just talks about the bravery of these people. So obviously, one of the first things I want to say to listeners is, if any of this rings true, you need to get in touch to Andy, because

it must be very frustrating for you. We're in the last months and years of being able to talk to these people. If they were 14 or so in 1940, they're going to be mid to late 90s. So, So just check, just check that your nan is not like Irene and can actually throw a pots and pan salesman down the footpath. And what about the archives? Presumably this stuff has been, the government has declassified this stuff now. Is there a paper trail here that you can exploit? Nope.

I don't know whether they've gone for a longer period of the official secret. Just because the people they were recruiting were so young, but there is, as far as we can see, there's nothing in the archives. There's the piece by Keith Jeffrey who obviously had access. to official MI6 content that's in the official histories. And actually interesting, Section 7 officially of MI6 is the accountancy arm. So they've hidden this resistance group under an accountancy arm. So even if you're looking up Section 7, MI6, you're just going to get accounts rather than ruthless resistors. So we are very much looking for that paper trail,

because it has to be paid for. There has to be some kind of paper trail somewhere, but we have yet to find it yet. Are we confident that you think you will one day? I hope so. Wouldn't that be amazing? I'm not sure when it will be released if it is, but we'll certainly keep searching because I'd just love to get an idea of just the number of people involved in this, because as I said, it's got the potential to be thousands and thousands. I mean, the auxiliary units was, we think, about six and a half thousand and the special duties branch about four and a half thousand, but this is the potential to be double that at least. So, yeah, much more than that. So this is huge potential to be an amazing story. And wouldn't it be great?

to get the last survivors some recognition, because there's been zero acknowledgement, zero recognition, nothing at all so far? Absolutely nothing. Yeah, no, no, exactly right. The only thing, as I said, is there's three paragraphs in the official history of MI6 kind of hidden, absolutely nothing from anyone. And actually, you know, it took years and years for the auxiliary units to get recognised. It was only in the mid-2000s that we managed to get them permission to walk past the Senate off, or remember on Sunday, for example. So, and that's the auxiliary units, which has essentially been in the public eye since David Lambert, that first book about it, in 1968. And there's certainly no medal for any of these groups. None of these groups were

officially given the defence medal, unlike the Home Guard. So yeah, absolutely no recognition at all, which is really awful, considering the sacrifice these guys were prepared to make in this country's hour of need. It's just such a fascinating story and exactly the kind of history I love. Every time we come back to it, we uncover something new, new artifacts, new stories, missing places, new details that beget more questions and, well, we realise there's need for more answers. So, as I say, if you've heard stories from family members like the ones Andy mentioned or stumble across something unusual while you're out walking the dog or exploring your local woods, we would love to hear from you.
