The ‘Bizarre’ British Vehicle That Could Drive Underwater To Surprise German Defences –  Hww

October 9, 1944. The Broekman Inlet, Scheldt Estuary, the Netherlands. As darkness fell, a convoy of enormous machines rolled toward the water’s edge. They were 23 ft long, nearly 10 ft tall, and sat on eight oversized rubber wheels. They looked like steel bathtubs mounted on a bus chassis. Nobody watching from the shore could quite believe what happened next.

The machines drove straight into the water. Their twin engines roared so loudly that German anti-aircraft guns across the estuary opened fire, mistaking the sound for incoming aircraft. These were Terrapins, British amphibious vehicles that could cross a mile of open water, climb a muddy bank on the far side, and deliver 20 armed soldiers directly into the German rear.

The men inside could not see where they were going. The driver sat blind between two screaming engines. A second crewman stood behind him, shouting directions over the noise. It was one of the strangest vehicles of World War II. It also played a crucial enabling role in one of the war’s most difficult campaigns.

By autumn 1944, the Allied advance across northwest Europe was choking on its own success. The armies had outrun their supply lines. The port of Antwerp, captured intact on September 4, had the capacity to handle 30,000 tons of supplies per day. That would have solved everything. There was one problem. German forces still controlled both banks of the Scheldt Estuary, the 54-mi waterway connecting Antwerp to the open sea.

Until those banks were cleared, the port was useless. Supply lines stretching back to the Normandy beaches were delivering barely 7,000 tons per day. Entire divisions were running short of fuel, ammunition, and food. The terrain made the problem worse. The Netherlands sits below sea level. The land consists of roughly 2,500 individual polders, each enclosed by raised dikes and kept dry by constant pumping.

The Germans understood this landscape and turned it into a weapon. They stopped the drainage pumps. They opened sluice gates at high tide to admit seawater. They breached dikes deliberately. Within weeks, vast areas of the battlefield were underwater. Roads that ran along the tops of dikes became narrow.

Exposed causeways four to five meters above the flooded fields, the water on either side was often too shallow for conventional boats, too deep and muddy for wheeled or tracked vehicles, and too soft to walk through carrying equipment. Assault boats could operate in some sectors, but across the worst flooded polders, the muddy uneven bottom made them impractical.

It was a treacherous hybrid landscape that stopped most conventional military movement entirely. The allies needed machines that could drive on roads, swim across open water, and crawl through flooded fields. The obvious answer was the American DUKW, a six-wheeled amphibious truck based on the proven General Motors lorry chassis.

The Americans had built over 21,000 of them. Britain received roughly 2,000 under Lend-Lease. That was not enough. The War Office issued a specification for a British alternative, and the contract went to John I. Thornycroft & Company, a firm with expertise in both commercial vehicles and shipbuilding, based in Basingstoke and Southampton.

Thornycroft faced a constraint the Americans never encountered. Britain could not spare any existing lorry chassis for conversion. Where the Americans had simply waterproofed a truck they were already mass-producing, Thornycroft had to design something from scratch. Their solution was unconventional. They built a boat-shaped hull from welded steel plate with no separate chassis underneath.

The hull itself provided both buoyancy on water and structural strength on land. Into this hull they mounted two Ford V8 petrol engines side by side in the center of the vehicle. Each engine produced roughly 85 to 95 horsepower, giving a combined output of between 170 and 190 horsepower. Each engine independently drove the four wheels on its side and one of two rear-mounted screw propellers.

This twin-engine layout created the Terrapin’s most distinctive characteristic. Steering was achieved by braking one side while powering the other, a system called skid steering. It worked identically on land and water, and it demanded constant physical effort from the brake levers. The wheel arrangement was equally unusual.

The Terrapin had eight wheels on four axles in an 8 by 8 configuration. On flat hard ground, only the four middle wheels touch the surface. The front axle wheels were raised high, specifically designed to help the vehicle clamber up muddy river banks when emerging from water. The rear axle wheels hung slightly above the surface and engaged only on soft ground or slopes.

Unladen, the Terrapin weighed 7 tons. Fully loaded with its 4-ton payload, it reached 11 tons. On land, it managed 15 mph. In water, the two propellers pushed it along at 5 mph. Manufacturing went to Morris Commercial Cars in Birmingham, since Thornycroft lacked the factory capacity for mass production. According to production records, around 500 Terrapin Mark I vehicles were ordered, with roughly 450 actually completed between late 1943 and 1944.

The vehicle carried no weapons and no formal armor, though its welded steel hull offered some resistance to small arms fire and shell splinters that the thin-skinned DUKW lacked entirely. Its crew consisted of just two men. The driver sat sandwiched between the two engines, behind the forward cargo hold, with almost no forward visibility.

The co-driver acted as a human periscope, standing behind the driver and shouting directions over the engine noise. If one engine failed in water, the surviving engine would drive the vehicle into a violent spin. Experienced crews could sometimes counter the rotation using the brake levers, but in rough water or under fire, it was a terrifying prospect.

This vulnerability was never fully resolved during the Terrapin service life. Now, before we see how this performed in combat, if you are enjoying this deep dive into British engineering, hit subscribe. It takes a second, costs nothing, and helps the channel grow. Right, let us get into the combat record. The Terrapin was originally intended for the D-Day landings, but it was never used on June 6, 1944.

That turned out to be fortunate. The rough channel seas that day sank numerous DD Sherman tanks and would almost certainly have swamped the short-hulled, open-topped Terrapins. Instead, the vehicle’s combat debut came 4 months later in one of the war’s most difficult campaigns. During Operation Switchback, Terrapins and Buffaloes of the 5th Assault Regiment, Royal Engineers, part of the 79th Armoured Division, carried the 9th Canadian Infantry Brigade across the mile-wide Braakman Inlet.

The assault force landed near the Hamlet of Hoofdplaat behind the German defensive line. According to Canadian records, the crossing was a surreal experience. As darkness fell, only tail lights showed. The Terrapin engines created a sound so like roaring aircraft that anti-aircraft guns across the estuary fired sporadically at nothing.

What had been planned as a diversionary attack succeeded so completely that it became the main effort, turning the German defenses from the rear and accelerating the clearance of the entire Breskens Pocket. 17 days later, on October 26, Terrapins carried elements of the British 52nd Lowland Division on a remarkable 13-km crossing of the Scheldt Estuary.

The assault force traveled from Terneuzen to a beachhead near Hoedekenskerke on South Beveland. This was an extraordinarily long water transit for a vehicle known to be easily swamped in rough conditions. The operation outflanked the German defensive line along the canal through South Beveland, which had been holding up the entire Allied advance.

There is an irony worth noting here. The 52nd Lowland Division was Britain’s only designated mountain division. Its first combat came not on mountaintops, but being ferried by Terrapins across flooded Dutch polders that sat below sea level. On November 1, 1944, the assault on Walcheren Island began. RAF Bomber Command had dropped 2,762 tons of bombs on the island’s dikes, flooding 80 to 85% of the interior.

What had been farmland and villages became a vast shallow lagoon ringed by massive sand dunes bristling with fortifications. An estimated 10 to 12,000 German troops of the 70th Infantry Division held defensive positions along the remaining dry ground. They were protected by over 50 coastal artillery pieces ranging from 75 mm guns to 220 mm heavy batteries.

Terrapins of the 6th Assault Regiment, Royal Engineers, navigated this flooded landscape. They carried troops and ammunition forward and evacuated wounded soldiers back across terrain that no other wheeled vehicle could cross. Surviving crew accounts describe appalling conditions. The water was freezing. The mud sucked at the wheels.

German artillery fire was constant. The stakes were enormous. Until Walcheren fell, the Port of Antwerp could not open. And without Antwerp, the Allied advance into Germany risked grinding to a halt. The Terrapin’s final major deployment came during Operation Plunder, the Rhine crossing on March 23, 1945.

The 79th Armored Division deployed roughly 600 Buffaloes as the primary assault vehicles, which made over 3,800 troops across the river. Terrapins served in a follow-up role, ferrying supplies and reinforcements after the initial assault waves had established bridgeheads on the far bank. How did the Terrapin compare to its rivals? Against the American DUKW, the disadvantages were stark.

According to comparative assessments, the DUKW was three times faster on roads at 50 mph. It had more than double the range at 400 miles. Its longer 31-ft hull handled rough water far better. It used conventional steering with a rudder, rather than the exhausting skid steering levers, and its driver could actually see forward. Critically, the DUKW’s single unified cargo bay could carry large indivisible loads like artillery pieces.

The Terrapin’s cargo area was split into two separate compartments by the centrally mounted engines, which negated much of its theoretical 4-ton payload advantage. The DUKW also pioneered the world’s first central tire inflation system, allowing the driver to adjust tire pressure while moving to match different terrain.

The Terrapin’s one genuine advantage was its steel hull, which provided some ballistic protection that the completely unarmored DUKW lacked. Germany, by contrast, never developed a heavy amphibious transport at all. The Schwimmwagen, Germany’s most produced amphibious vehicle at over 15,000 built, was a 25 horsepower Volkswagen derivative that carried just four men.

It was an amphibious scout car for officers, not a logistics vehicle. This reveals a strategic blind spot. Germany invested in individual tactical mobility. Britain invested in the capacity to move entire infantry brigades across water obstacles at division scale. When the flooded polders of the Netherlands turned the battlefield into a shallow lake, the Germans had nothing to match what the 79th armored division could deliver.

After the fighting stopped, the Terrapin story took a surreal turn. On Walcheren, the broken dikes were not fully repaired until October 1945, and the island remained partially flooded until early 1946. During this period, Terrapins were repurposed as civilian public transport, carrying Dutch residents across submerged village streets.

Newsreel footage from February 1946 shows military amphibious vehicles navigating flooded roads past horse-drawn carts, assault vehicles designed for war serving as island buses. A Mark II prototype had shown promise. With a longer 31-ft hull, forward driving position, unified cargo bay, and 5-ton payload, only five were built before the program was canceled.

The concept of a wheeled amphibious logistics vehicle lived on in the Alvis Stalwart, which entered British Army service in 1963 and addressed virtually every flaw that had plagued the Terrapin, serving until 1993. The vast majority of the original 500 Terrapins were scrapped. Today, surviving examples are among the rarest World War II vehicle survivors.

A single unrestored Terrapin exists in the Wheatcroft collection in Leicestershire. October 9, 1944, the Breackman Inlet. Those bizarre machines that rolled into the water carried 900 Canadian soldiers across a mile of open estuary and darkness. By dawn, the soldiers were behind the German lines. A diversionary attack had become a breakthrough.

The Terrapin was loud, blind, difficult to steer, and prone to swamping. It was also British, available when it mattered, and capable of crossing terrain that stopped everything else. Thornycroft took two Ford engines, eight wheels, and a steel hull, and built something that worked well enough under conditions that defeated conventional vehicles.

Post-war assessments were blunt. The vehicle was officially described as not an overall successful design, with many significant defects which were never overcome in service. But those same assessments acknowledged that it performed adequately in the specific critical role for which it was built. Not effortless superiority, but engineering pragmatism under pressure.

That is what British innovation looked like in 1944, and that is the Terrapin’s legacy.

QQ4 Bob Dylan and Keith Richards have been close friends for nearly 40 years. The friendship began on a live television program in November of 1986 in the 11 seconds after Bob Dylan called Keith Richards music derivative on camera. Keith Richard’s response to that assessment, one sentence said without anger, without performance, with the specific directness of a man who has nothing to prove and knows it made Bob Dylan laugh.

Then made Bob Dylan go quiet. then made Bob Dylan say two words that people who know Bob Dylan say he almost never said to anyone. This is the story of those 11 seconds and the 40 years that followed them. The program was a live music interview special broadcast on an American network on the evening of November 3rd, 1986. The format was simple.

Two musicians, a host, an hour of conversation about music and the state of it. The producers had assembled the pairing of Bob Dylan and Keith Richards with the specific calculation of television producers who understand that two people with equally strong and potentially incompatible views about what music is and what it should do will produce better television than two people who agree about everything.

The calculation was correct, though not in the way the producers had anticipated. Bob Dylan was 45 years old in November of 1986. Bob Dylan had released Empire Burlesque the previous year and had been on the road for most of the intervening period as part of the True Confessions tour with Tom Petty and the Heartbreakers.

Bob Dylan was in November of 1986 in one of the most prolific and restless phases of a career that had consisted almost entirely of prolific and restless phases. A career that had moved through folk, rock, country, gospel, and back again, that had been declared finished at least six times by the music press, and at each time continued with the serene indifference of a river to the opinions of people standing on its banks.

Bob Dylan had been redefining what music could be. Since 1962, Bob Dylan had invented and reinvented himself so many times that reinvention had become his defining characteristic, not in the superficial sense of a performer changing costumes, but in the deeper sense of a musician who had never allowed his work to settle into a form that could be anticipated or categorized from the outside.

Bob Dylan understood influence and originality and the relationship between them better than almost anyone alive in 1986. Bob Dylan had spent 24 years thinking carefully and specifically about where music came from and where music was going and what it meant that those two things were always in constant conversation with each other.

Keith Richards was 42 years old in November of 1986. Keith Richards had been playing guitar professionally since 1962. Keith Richards had built a career on a foundation of American blues and rhythm and blues. A foundation that Keith Richards had studied with the systematic devotion of someone who understood that the tradition he was building on was not incidental to the music he was making, but essential to it.

that you could not understand what Keith Richards did without understanding where Keith Richards had come from and what Keith Richards had been listening to since he was a teenager in Dartford with American Import Records and a secondhand guitar and no teacher except the recordings themselves. Keith Richards had never pretended otherwise. Keith Richards had in fact spent considerable energy across his career making the lineage explicit, naming the artists, citing the recordings, insisting on the acknowledgement of influence that the mainstream music

industry had a long history of suppressing or ignoring or crediting to the wrong people. If anything, Keith Richards was more transparent about his sources than most musicians of his generation. Keith Richards had always said openly that the Rolling Stones came directly from the blues, that Muddy Waters and Robert Johnson and the specific tradition of the Mississippi Delta were not background influences, but foundational ones.

The music Keith Richards made was in direct and sustained conversation with that tradition, something Keith Richards considered not a limitation, but a responsibility and a form of respect. The interview had been running for 8 minutes when the host asked Bob Dylan about the current state of rock and roll.

Bob Dylan answered with the density and the indirection that characterized Bob Dylan’s responses to direct questions, turning the question over, approaching it from an unexpected angle, finding his way to what he actually thought through a series of observations that moved like a river rather than a road. Bob Dylan was not a straightforward interview subject.

Bob Dylan had been asked about rock and roll in hundreds of interviews across 24 years and had developed the habit of treating the question as an invitation to think out loud rather than a request for a prepared position. The producer Gerald Sherman said afterward that in the first 8 minutes of the interview, he had been slightly anxious, not because anything was going wrong, but because nothing was going anywhere in particular yet.

The interview had the feeling of two conversations happening simultaneously. Bob Dylan’s internal one and the external one visible to the cameras. And Gerald Sherman was not certain in those first eight minutes that the two conversations would converge into something. Bob Dylan talked about influence. Bob Dylan talked about originality.

Bob Dylan talked about the difference between music that absorbed a tradition and transformed it and music that absorbed a tradition and reproduced it. And then Bob Dylan made his assessment. And then Bob Dylan said with the precision of a man making a musical assessment rather than a personal judgment that the Rolling Stones work, and Bob Dylan was specific, naming Keith Richards as the guitarist whose approach he was discussing was derivative in a way that Bob Dylan found limiting.

Bob Dylan said it without hostility. Bob Dylan said it as a technical observation about the relationship between source material and the work that came from it. Bob Dylan said that Keith Richards played the blues the way the blues had already been played, rather than using the blues as a starting point for something that had not yet been played.

Keith Richards had been listening to this with the specific attention Keith Richards gave to things being said about music by people who knew music. Keith Richards did not interrupt. Keith Richards did not shift in his chair or display any of the visible signals of a person preparing a defensive response. Keith Richards listened to Bob Dylan’s complete observation all the way to its conclusion without interrupting and without displaying any visible signal of preparing a response.

Then Keith Richards said one sentence. The sentence was not a rebuttal. The sentence did not defend Keith Richards music or argue for its originality or challenge Bob Dylan’s characterization of what the blues meant in the context of rock and roll. The sentence was something else entirely, something that required a specific kind of confidence to say.

The confidence of a person who has spent long enough thinking about the same things as the person they are talking to that they can locate the exact point where their thinking diverges and say something useful about that point rather than simply defending their own position. The sentence acknowledged everything Bob Dylan had said, the assessment, the distinction Bob Dylan was drawing, the specific musical concern underlying the observation, and then turned it 90°.

Keith Richards took Bob Dylan’s own framework, the one Bob Dylan had used to analyze Keith Richards relationship to the blues tradition, and applied it back to Bob Dylan’s work with the same precision Bob Dylan had used to apply it to Keith Richards. Spare aimed. The sentence asked Bob Dylan something about Bob Dylan’s own music, about the relationship between Bob Dylan’s sources and Bob Dylan’s output that Bob Dylan had not been asked on television before.

The sentence did not attack. The sentence illuminated. Bob Dylan laughed. The laugh was not the polite laugh of someone responding to a joke. The laugh was the involuntary laugh of someone who has been genuinely surprised. The specific kind of surprise that a person of exceptional intelligence experiences when someone else’s intelligence exceeds their expectations.

Bob Dylan laughed for 4 seconds. Then Bob Dylan stopped laughing. Then Bob Dylan was quiet for 3 seconds in the way that Bob Dylan was quiet when Bob Dylan was thinking rather than performing thought. Then Bob Dylan said, “You’re right.” The producer in the booth, a man named Gerald Sherman, who had been working in television for 14 years, said afterward that in 14 years of live television production, he had never heard Bob Dylan say those two words in a public forum.

Gerald Sherman said he had worked with Bob Dylan on two previous occasions and had observed Bob Dylan in numerous other contexts and that you’re right was not a phrase that Bob Dylan deployed easily or often because Bob Dylan had spent 24 years being right about music in ways that other people eventually caught up with. And the experience of being right ahead of everyone else does not generally produce a man who says you’re right readily when someone else makes a point.

The host of the program, a journalist named Patricia Wells, who had been interviewing musicians for 12 years, said afterward that the 11 seconds between Bob Dylan’s assessment and Bob Dylan saying, “You’re right,” were the most extraordinary 11 seconds of television she had been present for. Patricia Wells said that what she witnessed in those 11 seconds was not a debate or a confrontation or a celebrity exchange of competing opinions.

Patricia Wells said what she witnessed was one musician recognizing another musician as an equal, which was in the specific context of Bob Dylan in 1986, not something that happened in public very often. The interview continued for another 42 minutes after those 11 seconds. The conversation between Bob Dylan and Keith Richards in the remaining 42 minutes was described by everyone who watched it as fundamentally different from the first 8 minutes.

The host, Patricia Wells, who had been conducting music interviews for 12 years and understood the difference between the performance of conversation and actual conversation, said that at approximately the 9-minute mark, something shifted in the studio. That the formal interview, architecture dissolved, and what replaced it was something less structured and more genuine.

Bob Dylan and Keith Richards talked about influence and originality and the blues and what it meant to build on a tradition without being consumed by it. They talked about specific recordings and specific musicians with the specificity of two people who had spent their entire adult lives thinking about these things and rarely found another person who had thought about them with equivalent care.

They talked about where music came from and where music was going and whether those two questions were actually one question or two. Patricia Wells said afterward that she had asked approximately four questions in the remaining 42 minutes because Bob Dylan and Keith Richards did not require questions. They required only a room and a camera and the shared understanding that what they were saying together was worth recording carefully.

She said it was the best interview she had ever conducted and that she had conducted the smallest part of it. After the program, Bob Dylan and Keith Richards were in the corridor outside the studio when the host Patricia Wells passed them. Patricia Wells said she did not stop because she did not want to interrupt.

She observed them for approximately 30 seconds from a distance. She said they were talking with the ease of people who had known each other for years rather than people who had met for the first time 2 hours earlier. She said that something had shifted between them during the broadcast that the broadcast had made permanent rather than temporary.

She continued down the corridor and did not look back. She said in her account of that evening that she had decided in that moment not to interrupt the conversation because some conversations are more valuable than any question a journalist might ask and that the conversation she had observed for 30 seconds in the corridor outside the studio was one of them.

She had been a music journalist for 12 years. She recognized the difference. Bob Dylan and Keith Richards have maintained their friendship across four decades. They have appeared together at various events, most significantly at the concert for the Rock and Roll Hall of Fame in 1995, where people who were present described them as inseparable for most of the evening, occupying the same corner of the backstage area and talking with the concentrated attention of people who only have a limited amount of time together and intend to use it

well. Bob Dylan has spoken about Keith Richards in interviews with the specific thoughtful care that Bob Dylan reserves for musicians whose work Bob Dylan considers genuinely important rather than merely culturally prominent. Keith Richards has spoken about Bob Dylan in similar terms with the specific respect of someone who recognizes in another person a commitment to music that goes deeper than career.

Neither Bob Dylan nor Keith Richards has made a public statement specifically about how the friendship began or about the November 1986 interview. Bob Dylan has not mentioned the 11 seconds. Keith Richards has not mentioned the sentence. The interview exists in the archive. The 11 seconds are there. The laugh is there. The two words are there.

What is also there for anyone who watches the interview from its beginning and pays attention to the shift that happens at the 9-minute mark is the specific moment when two people who thought they were appearing on a television program discovered they were actually talking to each other. What Keith Richards said in that one sentence has never been officially reported.

The people who were in the studio that evening, Gerald Sherman, Patricia Wells, the floor crew, the two camera operators, the makeup artist who was watching from the side of the set, have described the sentence in consistent terms. They have described its effect. They have described Bob Dylan’s laugh and Bob Dylan’s silence and Bob Dylan’s two words.

They have not repeated the sentence itself in the specific understanding that the sentence was said between two musicians on a television program and that its power resided in the specific context of that exchange and would not survive removal from it intact. What can be said is this. Keith Richards said something to Bob Dylan about Bob Dylan’s music that used Bob Dylan’s own observation about Keith Richards as its starting point and arrived somewhere that Bob Dylan had not anticipated.

Keith Richards turned Bob Dylan’s assessment 90° and showed Bob Dylan something about the music they had both spent their lives making that Bob Dylan recognized immediately as true. And Bob Dylan said, “You’re right.” Two words said by Bob Dylan in public on live television in 1986 to Keith Richards in response to a single sentence Keith Richards had said about music.

Two words that Gerald Sherman, who had worked with Bob Dylan on two previous occasions, said he had never heard Bob Dylan say in a public forum. Two words that Patricia Wells, who had been interviewing musicians for 12 years, said were the most significant two words she had heard in those 12 years. Not because of their content, but because of who said them and what it cost to say them and what it meant that Keith Richards had produced them in 11 seconds from a conversation that began with Bob Dylan calling Keith Richards’s music derivative. And Keith Richards and

Bob Dylan have been close friends for nearly 40 years. The sentence did its work in 11 seconds on the evening of November 3rd, 1986. The work has been ongoing ever since.
