1943, Bovington training grounds, Dorset. A crew of British tankers climbs aboard a 28-ton Crusader tank, fires the engine, and waits. The engine coughs. It shudders. It stalls. They try again. The 12-cylinder petrol engine finally catches, belching black smoke from an exhaust that runs far too hot.
The tank lurches forward at barely 24 mph, already slower than the Cromwell parked beside it, a tank built on the exact same hull. The difference is the engine. The Cromwell runs a Rolls-Royce Meteor producing 600 horsepower. The Centaur runs a Nuffield Liberty producing 395. The Liberty was designed in 1917 for an airplane in the First World War.
And somewhere in Normandy, a version of this tank will go to war carrying a wooden gun barrel instead of a real one. This is the Centaur, the tank that fooled nobody, fought anyway, and mattered more than anyone expected. To understand why Britain built a World War II tank around a World War I engine, you have to understand the crisis it was meant to solve.
By late 1940, British cruiser tanks were failing. The Crusader, backbone of the desert war, was mechanically fragile, thinly armored, and armed with a 2-pounder gun that could not kill German medium tanks at combat ranges. The new Panzer IV carried 80 mm of frontal armor and a long-barreled 75-mm gun capable of destroying anything Britain fielded.
British tank losses in North Africa were catastrophic. The General Staff issued an urgent requirement for a replacement cruiser tank armed with the new 6-pounder gun, protected by 76 mm of frontal armor, and in service by 1942. Three firms submitted designs in January 1941.
Nuffield offered the A24 Cavalier, essentially a stretched Crusader with the same Liberty engine the company had been building for years. Leyland Motors offered the A27, a cleaner design with a new Merritt-Brown gearbox. Birmingham Railway Carriage and Wagon Company proposed fitting the same A27 hull with a radically different engine, the Rolls-Royce Meteor.
The Meteor’s origin story is worth telling. According to Rolls-Royce company records, W.A. Robotham, head of the chassis division at Clan Foundry in Belper, had been collecting crashed Merlin aero engines, ones too damaged for aircraft but still rebuildable. His team stripped one of its supercharger, reversed its rotation for ground use, and installed it in a Crusader test hull.
Delivered to Aldershot on April 6th, 1941, the prototype was so fast that testers reportedly could not time it accurately. Estimating roughly 50 mph, the Meteor shared the Liberty’s 27-liter displacement exactly. It produced 600 horsepower against the Liberty’s 395. Same engine volume, nearly double the power, a quarter century of engineering progress in a single comparison.
Leyland agreed to produce a thousand Meteors. Then Leyland reversed course, citing cooling concerns, and chose to stick with the familiar Liberty. The Ministry of Supply, rather than forcing the issue, split the program three ways. The Cavalier would use the Liberty and the old transmission. The Centaur, designated a 27L, would use the Liberty but with the new Merrit Brown gearbox.
The Cromwell, designated a 27M, would use the Meteor. The A27 hull was deliberately designed to accept either engine, enabling future conversion. The Meteor supply bottleneck was genuine. Every Rolls-Royce production line was building Merlins for Spitfires, Hurricanes, Lancasters, and Mosquitoes. Early Meteors came only from salvaged crash parts.
The breakthrough arrived through a remarkable industrial swap. According to Rolls-Royce historical accounts, Ernest Hives of Rolls-Royce and Spencer Wilkes of Rover met at the Swan and Royal pub in Clitheroe in late 1942. Rover had been struggling with Frank Whittle’s jet engine program. The two men agreed over dinner to trade responsibilities.
Rover would take Meteor production. Rolls-Royce would take the jet. The handover took effect on January 1st, 1943. But Rover needed American machine tools that took months to arrive. Sufficient Meteor engines did not flow until mid-1943. The Centaur existed to keep tank factories running during the gap. It was a placeholder from the day it was born.
How bad was it in practice? During exercise Dracula in August 1943, a 2,300-mi endurance trial pitting the Centaur against the Cromwell and the Sherman, the Centaur finished last. According to the official trial report, it arrived at night bases hours after the other tanks. A November 1943 retest confirmed the pattern.
The Liberty ran dangerously hot under the 28-ton load. The Cromwell delivered 21.4 horsepower per ton. The Centaur managed 14.1. The Sherman sat at 15.2. Even the German Panzer 4 at 12 horsepower per ton had a more reliable drivetrain. Roughly 950 Centaurs were completed with Liberty engines. None were cleared for frontline combat as gun tanks.
Now, before we get to the part where this tank actually fights, if you are enjoying this deep dive into British engineering compromises, hit subscribe. It takes a second, costs nothing, and helps the channel grow. Right, back to the Centaur. So, what do you do with 950 tanks that cannot fight? You find other uses. The Centaur spawned nine variants.
The Mark 1, armed with a six-pounder, became a training tank for crews destined for Cromwells since the controls were identical. The Mark 3 was re-gunned with a 75-mm weapon. Then most were re-engined with Meteors and redesignated Cromwell 4s. The Centaur AA mounted twin 20-mm Polsten guns for anti-aircraft defense.
The Centaur Dozer had its turret removed and a bulldozer blade fitted, converted by the MG Car Company at Abingdon. Between 200 and 250 were produced, serving with the 87th Assault Dozer Squadron of the 79th Armoured Division, one of Hobart’s Funnies. Then there was the Centaur OP, the observation post variant. This tank carried a wooden dummy gun barrel in place of the real weapon, freeing turret space for extra radio sets and map tables.
It served as an artillery spotter and formation command vehicle alongside real Cromwell’s from Normandy to Germany. The wooden barrel was a tactical choice, making the vehicle visually identical to armed tanks, so the enemy would not single it out as a high-value target. The Imperial War Museum holds one today marked as 7th Armored Brigade Northwest Europe 1944.
It fooled nobody into thinking the Centaur was a great tank, but the wooden gun fooled German gunners into thinking it was not worth special attention. That was enough. The one variant that saw real combat was the Mark IV, armed with a 95-mm howitzer carrying 51 high-explosive rounds. 114 were produced and assigned to the Royal Marines Armored Support Group.
Formed on March 14th, 1944 under Brigadier D. C. W. Sanders, the unit fielded 80 Centaur IVs and 20 Sherman V’s organized into five batteries. Each troop had four Centaurs and one Sherman for the troop commander. Remove the Centaur engines entirely and remove the Centaur engines entirely and mount the turrets as static guns on raised platforms inside landing craft tank vessels.
This suited the Royal Marines naval gunnery heritage, but the raised platforms made the landing craft dangerously top-heavy. According to unit records, several capsized during training exercises off England’s south coast. Then, legend has it, Field Marshal Montgomery observed a demonstration and demanded to know why the tanks were not driving off the beached craft to support the infantry.
In February 1944, just 4 months before the invasion, engines were reinstalled, drivers trained, and wading equipment fitted. On June 6th, 1944, the Royal Marines Armored Support Group hit three beaches. The 1st Regiment supported the 50th Division on Gold Beach, the 2nd supported the 3rd Canadian Division on Juno Beach, the 5th Independent Battery supported the 3rd British Division on Sword Beach.
48 Centaurs landed within 4 hours of H-Hour. 20 were ashore within the first 15 minutes. The turrets carried distinctive compass graduation markings, 180° at front and 360° at rear, enabling the gun position officer on the landing craft bridge to call bearings and coordinate fire. Essentially, naval broadside techniques applied to tank howitzers.
This made the Centaurs the only tanks on D-Day capable of firing a coordinated barrage on a single target. The after-action report recorded 10 guns engaging shore targets during the run-in approach. Once ashore, 14 fired indirectly and eight engaged targets with direct fire. Many were disabled by mines, enemy fire, or drowning in the surf.
On Gold Beach, a Sherman was destroyed by 88-mm fire, its entire crew killed. The regiment’s headquarters craft was sunk. According to surviving accounts, the wounded second-in-command eventually obtained a German staff car to continue operations. Despite orders limiting them to 1 mile from the waterline, the Centaurs fought for 15 days and pushed up to 10 miles inland.
On Sword Beach, the fifth battery supported commandos and participated in the capture of Douvres radio station. Brigadier Sanders was killed during the Normandy campaign. The most dangerous enemy proved to be the transport itself. The top-heavy, low-freeboard landing craft caused more casualties to the Royal Marines armored support group than enemy action.
Landing craft tank 2428, carrying two Centaurs to Juno Beach, capsized in the English Channel on the night of June 5th. Its tanks now rest on the seabed in Bracklesham Bay, West Sussex, at 20 m depth, discovered by divers in 2008. After June 20th, the unit was disbanded. Surviving Centaur IVs went to Free French forces and later to the first Canadian Centaur battery, supporting the 6th Airborne Division.
The Centaur dozers outlasted every other variant, serving through Korea and the Suez Crisis of 1956, 12 years after the war ended. Total of 27 production reached roughly 4,016 tanks. About 950 retained their Liberty engines as Centaurs. 3,066 received Meteors and became Cromwells. Around 200 Centaur ones were re-engined and redesignated.
The tank the army wrote off as a training aid produced more specialized variants than any other British cruiser of the war. Today, one Centaur four stands at the Pegasus Bridge Memorial in Normandy. Its name is Vidette. It landed on Sword Beach between Hermanville and Lion-sur-Mer on June 6th, 1944. Hit by mortar fire 500 yards from the waterline, its engine compartment blazed.
The crew abandoned it on the sand. It sat there for 31 years. In 1975, 7th Field Workshop of the Royal Electrical and Mechanical Engineers recovered it, restored it, and placed it where it stands now, one of the most visited tank memorials in France. The Centaur was a compromise, a tank built because one company preferred an engine it knew over one that was better, and because a ministry chose industrial harmony over decisive action.
Its World War I engine produced barely 2/3 the power of the Meteor from identical displacement. It was too slow, too unreliable, too outdated for the war it was built to fight, but in the specific, violent, narrow front conditions of D-Day, 80 of them, crewed by Royal Marines applying centuries of naval gunnery discipline to tank howitzers, delivered fire that kept German defenders pinned while infantry crossed the most dangerous beaches in history.
The tank with the wooden gun served undetected from Normandy to Germany. The tank with the bulldozer blade outlasted them all. British engineering did not create the Centaur on purpose. British pragmatism found a way to make it count.
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.
