The Covenanter Bridgelayer

In this video/article we will examine some rare footage of the Covenanter Bridgelayer in action. The footage is available to watch on the BFIs website and originally comes from the Wessex Film and Sound Archive. The 16mm film was filmed at some time in August 1942 but little else is said about locations in the BFI archive entry for the footage.

The tank’s hull number is visible as T.18434 which I think would make it one of the earliest English Electric-built Covenanters. The covenanter was developed in the late 30s as a cheaper cruiser tank. It entered service in 1940, but saw limited active service – instead being largely used in training roles. The bridge element of the vehicle was a Scissors Bridge 30ft, No. 1. – it was deployed and recovered by a clutch and 2 to 1 reduction gear, it was powered directly from the tank’s engine.

*Cruiser Mk V Covenanter III (A13 Mk III) (IWM KID 778)*

A US report on the Covenanter Bridgelayer explains how it worked:

“The opening of the bridge begins after the launching mechanism has begun to pivot on the rollers of the launching frame. Since the cables are of fixed length, they act to open the bridge as it is pivoted about the rollers.
Having been laid across the obstacle, the bridge is disengaged from the prime-mover [the tank itself]. The bridge is then ready for the passage of other vehicles.
To retrieve the bridge, the prime-mover crosses the bridge to the far side of the obstacle, hooks up to the bridge, pulls it back to the traveling position, and is then ready to proceed to the next obstacle.”

*Illustrations of the Covenanter Bridgelayer from a US Military Intelligence Service Tactical and Technical Trends report, 1942*

The bridge had a span of 34 feet and vehicles up to 30 tons could cross it. It could be deployed in under 3 minutes and in total the bridge and the system which launched it was 3.5 tons. The vehicle had a two man crew, with a driver and a commander.

Above is a British Pathe newsreel that gives us a closer look at some of the Bridgelayer’s mechanism at work.

The US report also noted that “In one case 1,200 successful launchings and recoveries were made by one vehicle without undue maintenance.” The system was only mounted on a small number of Covenanters. One source suggests 20 Covenanter I and 60 Covenanter IV tanks were converted into Bridgelayers. Far more Valentines were equipped with them and subsequently the Churchill AVRE became the British Army’s primary bridging tank.

*A later Valentine Bridgelayer in action in Burma, 1945 (IWM)*

No location is given for the footage but the presence of a number of barrage balloons to the rear is intriguing! It may have been filmed at the Royal Engineers Establishment at Christchurch or at another demonstration elsewhere. Scissor Bridges, with similar basic designs remain in service with numerous militaries around the world today.

Shoot To Live

‘Shoot to Live’ is a British Army marksmanship training pamphlet published in the late 1970s and early 1980s

‘Shoot to kill’ had long been a British Army slogan, appearing in numerous training films and pamphlets. One training film from the 1970s, which features in our video, can be watched here.

But in the late 70s and early 80s a new introductory pamphlet on marksmanship filed the old slogan on its head. In the video above we take a look inside an original copy of ‘Shoot To Live’.

Below are some pages from the booklet:

So You Want To Buy An Oerlikon?

In this video we take a look at an original 1970s brochure for an Oerlikon 20mm Cannon. The booklet, printed in 1974, covers the Type GAI-BO1 – which had previously been designated the 10ILa/5TG. The Swiss Oerlikon had been introduced in the mid-1930s and seen widespread on both sides use during the Second World War.

*Engagement of Ground Targets (Matthew Moss)*

The brochure covers the anti-aircraft and ground roles the cannon was capable of fulfilling as well as explaining the major assemblies of the weapon and some of the accessories like sights and magazines. The brochure also lays out some of the ammunition available for the Oerlikon, ranging from practice shells to fragmentation HE incendiary and armour-piercing hard core shells. The Oerlikon cannon remains in production and in service with dozens of countries around the world.

WW2 Makeshift Sten Foregrips

A couple of weeks ago we looked at some photographs showing an interesting modification seen on a STEN MkII held by Deputy Prime Minister Clement Attlee. The STEN Attlee posed with had a front grip added, something the MkII didn’t typically come with.

A few people very kindly sent me some other contemporary photos showing other ad hoc STEN front grips so I thought a follow up video was needed. I also found a group of photographs taken in June 1943 at the Combined Training Centre at Kabrit, in Egypt. The photos show groups of Commandos and the Royal Navy’s Naval Beach Parties armed with Stens with a pretty standardised style of front grip.

*Commandos on parade with STEN MkIIs equipped with ad-hoc front grip, at Kabrit in June 1943 (IWM A17755)*

In these photos we can see the men training with the STENs and the front grips are quite clear. It’s especially interesting in that it isn’t just the Commandos who have the front grips but also men of the Naval Shore Parties. It’s also relatively rare to see STENs in North Africa. You might have seen some of these photos, taken by Royal Navy photographer Lieutenant L.C. Priest, in our video looking at the unusual fighting knives the Commandos are equipped with.

The plethora of photos from Kabrit show a fairly standardised design for the grip. A metal ring, seemingly tightened by a wingnut on the left side and a generous wooden grip that was long enough to fit all four fingers on. The grip appears to have some finger grooves and a fairly standard shape. A photo (see above) of Naval Commandos on parade shows the men with the STENs tucked under their arms, holding the front grips. This is identical to how the STEN MkI with its front grip was paraded with. The photo also gives us a good look at the uniformity of the grips.

*RAF Regiment Corporal cleans his STEN MkII, equipped with a makeshift front grip (IWM CM4296)*

While the photos from the Combined Training Centre at Kabrit represent the largest number STEN front grips seen in one place and several units there are a few other photos which are really interesting. First up is this photograph of a Corporal from the RAF Regiment taken in Libya sometime in 1943. The Regiment had been formed just a year earlier. The corporal is sat cleaning his STEN MkII with the butt removed but the bolt still in the weapon. On the barrel nut of his weapon he has a wooden front grip. Again seemingly attached to a metal band around the barrel nut. The wooden grip appears to have some rudimentary finger grooves. Sadly, I couldn’t find any other photos of this Corporal and his STEN. But the design of his front grip is very similar to those seen in the Kabrit training photos and could well be of the same origin.

Finally, we have a photograph from a completely different theatre – Burma. The caption for this photograph reads: “Men of the 2nd York and Lancaster Regiment searching the ruins of a railway station for Japanese snipers, during the advance of 14th Army to Rangoon along the railway corridor, 13 April 1945.” This soldier’s STEN MkII has a grip just in front of the trigger mechanism cover and behind the magazine housing and ejection port. It’s actually in a position close to that of the original STEN MkI’s integral folding pistol grip.

*Soldier of the 2nd York and Lancaster Regiment with a STEN MkII outfitted with a homemade front grip, Burma 1945 (IWM SE3804)*

At the end of the day the adaptation is a good idea, a front grip provides a means of pulling the weapon into the shoulder and a more natural place to grasp other than the barrel nut, the trigger mechanism housing or the magazine – which was discouraged. It is interesting to note that I’ve yet to see any examples of a MkIII being fitted with a front grip like these.

This is certainly something I’m going to do more research into to see if there’s any documentary reference to the use of front grips like these. With the introduction of the MkV, with its front grip, it seems that the idea was sound enough. If you know of any other examples let me know in the comments!

Kabrit Commando Knife

While doing some research for a couple of upcoming videos I came across some photographs of Commandos training, at the Combined Training Centre at Kabrit in Egypt, which showed men equipped with some interesting fighting knives.

Typically when we think of Commandos and fighting knives we think of the Fairbairn-Sykes fighting knife with its stiletto point and cast grip. So much so that it became the iconic symbol of the Commandos.

Well these Royal Navy Commandos appear to be armed with fighting knives crafted from earlier standard issue bayonets. The knives have the standard stiletto blade but quite clearly do not have the Fairbairn-Sykes’ instantly recognisable cast ringed grip.

*Commandos training in hand to hand combat at Kabrit in June 1943 (IWM)*

In the series of photos taken during training at Kabrit, we can see numerous Commandos equipped with them and featuring in some quite dramatic photos from June 1943 – seemingly taken during training for Operation Husky. At first I thought the knives might have been made from the still-in-service 1907 Pattern sword bayonet used by the SMLE No.1 Mk.3. In some of the photos the scabbards appear to look like shortened 1907 bayonet scabbards with the same brass fittings and the knives appear to be retained by Pattern 1908 webbing bayonet frogs.

I also thought they might have been adapted from the even earlier 1888 Pattern bayonet for the Lee-Metford. But while they have a scroll to the front of their quillon/cross guard the shape of the pommel and the bayonet attachment point clearly differ.

*Naval commando with STEN MkII (with curious pistol grip) and a Commando knife made from a 1903 pattern bayonet (IWM)*

Not being a bayonet expert I was a little stumped so posted about the photos on twitter and Kevin Dann was kind enough to mention that the knives are in Ron Flook’s book on British & Commonwealth Military Knives. Flook identified the knives as adapted 1903 Pattern Bayonets, originally introduced with the SMLE before the move to a longer bayonet.

*Naval commando training June 1943 (IWM)*

It seems that these knives were used by Commandos and they are also seen in some photos of SAS operating in the Aegean. I’m not sure who made these knives, some sources mention Wilkinson Sword making some F/S style knives from old 1888 and 1903 bayonet blades but state these had different grips. Perhaps these were put together by a unit armourer if proper issue knives weren’t available.

Home Guard Improvised Incendiary Weapon

On the 14th May 1940, the British Government announced the formation of the Local Defence Volunteers. By the summer of 1940 nearly 1.5 million men had volunteered to serve. The force was later renamed the Home Guard in July 1940 but remained under-equipped throughout the summer of 1940. Many of the newly raised militia units had just ‘LDV’ arm bands, some civilian firearms and improvised weapons, as uniforms and service weapons were in short supply.

I recently came across a really interesting piece of footage showing a Hampshire Home Guard unit training with an ‘incendiary weapon’. With few heavy weapons available during 1940, some Home Guard units improvised. This remarkable original colour footage appears to show a reasonably effective incendiary weapon of some sort. But beyond what we can see we know very little about the weapon.

The footage shows a battery of five launchers, each seemingly with a 3 man crew. One man aiming, another loading and another firing. The footage is undated but from their arm bands we can see that the men are Home Guard so definitely post July 1940. The men also appear to be quite well equipped with caps, denim trousers and blouses and belts. No webbing is seen but we can potentially date the footage to between late 1940 and mid-1941.

*Crews dash to their launchers. Note the rifle stock-shaped pieces to the side of the weapons which appear to have been used to aim the launcher*

The incendiary weapon itself is extremely intriguing! I haven’t seen a similar weapon before and I couldn’t find any direct reference to it in the available original documents, newspapers or photos. The footage comes from the Wessex Film and Sound Archive, it is described as showing Home Guard men from Swanmore, a rural village in Hampshire, demonstrating the weapons. Before the incendiary weapon is demonstrated we see a company sized force of Home Guard parading, without rifles or other equipment, and then a single Home Guard member demonstrates loading an SMLE. From the footage we can get an idea of how the weapon would have worked.

*Three-man crews sit by their weapons note the troughs projecting from the front of the launchers*

The men run to the launchers, which appear to be made of wooden boards. Beneath them are rifle stock shaped pieces which the man at the rear seems to shoulder – probably to aim the weapon. The other two crew members kneel either side of the launcher. The footage then cuts away to another angle from the other side and shows one of the kneeling men hitting the rear of the projectile with a hammer. Then with a flash and puff of smoke the projectile launches forward. The man who aimed the weapon appears to have moved away, out of shot. Frustratingly the footage is a bit underexposed and quite dark so we can see too much more detail but we can see that the chap with the hammer is definitely hitting the rear of what looks like a length cylinder. The cylinder shoots to the rear while a projectile fires forward and the launcher’s crew look downrange.

A somewhat low resolution close-up of the launcher. Note the crew member lying behind it aiming it along the wooden piece on the right. The projectile and launch cylinder sit in a trough while behind appears to be a shield to protect the crew member aiming

We then get footage showing what seem to be a series of impacts, likely from the projectile’s fired by the launchers. Then we get another clip of the men running to man the launchers and some more shots of the incendiary weapons exploding. From the available footage its pretty difficult to theorise how the launchers work. They appear to be using an almost proto-recoilless rifle-like principle with the launch cylinder shooting backwards and the projectile leaving the cylinder and firing towards the target. The crew member with a hammer may be hitting a percussion cap to detonate some black powder which projects the incendiary bomb. This system may have been developed to remove the need for a fixed, pressure bearing barrel. Making the weapon much simpler to manufacture.

*The effect down range – the target well alight*

The footage doesn’t give us too much indication of the range of the weapon but it’s distant enough that the men firing the weapon don’t appear to recoil when the projectile hits the target. The incendiary effect downrange is actually quite impressive and a battery of five of the launchers would have been an impressive sight and perhaps quite useful as a road ambush weapon which was something the Home Guard focused heavily on at the time.
It wasn’t until later in 1941 that sub-artillery like the Smith Gun, Northover Projector and the Blacker Bombard began to enter service with the Home Guard. Until then some of the units took it upon themselves to create their own weapons, improvising contraptions like the one featured in this video.

Update 28/07/21:

The weapon somewhat fits the description of the ‘Jones-Wise Projector’ shared by David Lister in his book Forgotten Tanks and Guns. Thanks to BettongMI who brought this to my attention in the comment section of the video. The weapon was apparently developed by a pair of Home Guard officers and while turned down for regular service was used by some elements of the Home Guard in southern England, at least until official sub-artillery began to enter service.

Unpacking 60 Years of Military History

Today we have a bit of an interesting unpacking/unwrapping video. I’ve saved up a few parcels with some new additions to the TAB reference collection and I thought I’d bring you along for the ride. The manuals we’ll be taking a look at span about 60 years of British Army doctrine and weapons. The materials range from a Hotchkiss machine gun manual from 1917 to an AFV identification handbook from the late 60s. There’s some quite interesting and rare stuff here including a 1951 provisional manual for the 3.5in rocket launcher.

These manuals and this sort of primary material is really important because we can learn how the weapons were actually intended to be used. It’s support from our Patreon supporters that enables us to pick up items like these to share in videos. So if you’d like to support our work, check out the TAB Patreon page here.

A Hill In Korea & the 70th Anniversary of the Battle of The Imjin River

This week marks the 70th anniversary of the Battle of the Imjin River, the Korean War battle perhaps most closely associated with the UK’s involvement in the conflict. Sadly, Korea remains a largely forgotten war and only one film has ever been made about the British Army’s experience 1956’s ‘A Hill In Korea‘. In this video we’ll discuss the battle, the super bazooka and the classic war film!

The film follows a fighting patrol which is cut off behind enemy lines and forced to fight a desperate last stand. The film borrows elements from the battle of Imjin River and the war as a whole. Today it is best known for its strong cast including Stanley Baker, Robert Shaw, Harry Andrews and George Baker and for being Michael Caine’s first film credit. Interestingly, Caine was a veteran of the war, having served with the Royal Fusiliers during his National Service.

We recently covered the film in an episode of our Fighting On Film podcast and a scene featuring a 3.5in Rocket Launcher stood out. The patrol uses the rocket launcher against a Chinese tank, which appears to be a captured British Cromwell. The film shows the bazooka being assembled and its team moving closer, stating that to be sure of a hit they want to be just 80 yards away. This is comparatively close for a 3.5in rocket launcher, which had an effective range of 300 yards.

*The Bazooka team take on the Chinese Cromwell*

The 3.5in was a brand new weapon in 1951. It had been developed in the US before the start of the war and facing communist T34/85s it was rolled out to most of the UN ground forces in the theatre (alongside recoilless rifles and smaller M9A1 rocket launchers). Better known as the M20 Super Bazooka in US service urgent operational requirements saw the 3.5in R.L. replace the PIAT as the British infantry’s platoon anti-tank weapon. In the TAB reference collection we are lucky enough to have an original copy of the provisional manual for the 3.5in R.L. which was compiled during the war in 1951.

*The anti-tank team who operate the 3.5in R.L. in the film*

The film shows the weapon being fired twice, successfully knocking out the tank. It’s perhaps the only depiction of British troops using the 3.5in rocket launcher and certainly one of the better depictions of it in film. We don’t get to see the rocket being loaded but we do see the No.2 attaching the contact wires at the rear of the tube. The first round hits the tank’s hull while the second strikes the track and the tank rolls backwards and explodes! Once the rocket launcher team get back to the main defensive position we even see the No.1 breaking the weapon down into its too parts.

During the battle of Imjin River itself, the bazooka was put to good use by a number of units including the Gloucestershire Regiment, the Royal Ulster Rifles and the Belgian battalion. Using the weapons to knock out Chinese machine gun positions and break up the human wave assaults. During an attack on Gloster positions in the early hours of the 22^nd April, Lance-Corporal Joe Farrell recalled how the Glosters blasted Chinese troops using some boulders as cover. After three days desperate fighting the 29^th Infantry Brigade had lost almost a quarter of its strength, suffering over 1,000 casualties. The rest managed to fight their way out.

*Royal Northumberland Fusiliers advancing to positions on the Imjin River, April 1951, (IWM)*

I felt it was important to discuss the battle on its 70th anniversary as it sadly continues to be largely forgotten. The Glosters and the men of 29th British Independent Infantry Brigade Group fought a very hard battle against massively overwhelming odds, I would definitely urge you to read more about the battle and the war itself. I would also recommend seeking out A Hill In Korea, it is a fascinating film.

Cold War British Army Threat Recognition Guide

It’s the 1980s and the British Army Of the Rhine is still stationed in West Germany facing down the USSR’s forces. The Cold War has gotten hot and the 3rd Shock Army is approaching your dugout but how do you differentiate a BTR from a BMP? This handy British Army THREAT Recognition Guide booklet gives you everything you need to know about the Soviet armour, infantry and aircraft you’re facing!

Continuing on from our earlier look at a British Army threat Recognition Guide to Iraqi Ground Forces issued during the Gulf War, we dig into the TAB reference collection again and take a look at this Threat Recognition Guide looking at Soviet air and ground forces facing the British Army of the Rhine in the 1980s.

The Group of Soviet Forces in Germany (GSFG) in East Germany throughout the Cold War were an ever present threat to West Germany and NATO. This recognition guide covers all of the USSR’s main battle tanks, armoured personnel carriers, and infantry fighting vehicles, as well as artillery systems and some of the close support aircraft which would have accompanied the attacking Soviet forces.

The pages of the recognition guide include photographs, diagrams, basic specs and recognisable features of the various enemy vehicles. It was put together by the Intelligence Directorate of BAOR’s 1 Corps.

The MB-1 ‘Genie’ – The USAF’s Unguided Air-To-Air Nuke

The MB-1/AIR-2 ‘Genie’ was the world’s first nuclear-armed air-to-air weapon and remains the most powerful missile ever deployed aboard U.S. Air Force interceptors. Developed as the Cold War began to heat up it would be carried aboard a succession of aircraft including the F-89, F-101B Voodoo, and the F-106 Delta Dart.

The MB-1 (later the AIR-2) was an air to air rocket with a 6 mile range and a 1.5 kiloton W25 nuclear warhead. It was ostensibly a tactical nuclear weapon designed to take on Soviet strategic bomber formations. The early 1950s saw the Soviet Union’s strategic bomber capability expand from the Tu-4, B-29 Superfortress copy, to include the Tupolev Tu-16 and Tu-95 and the Myasishchev M-4. These new long-range, nuclear capable bombers posed a serious threat to the continental United States. It was decided that only nuclear anti-aircraft weapons could counter the new high-flying Soviet bombers. Development began in 1954 with the project code-named “Genie” by the Air Research and Development Command.

We’ve previously looked at the Boeing BOMARC, the world’s first long-range surface to air missile, whose role was similar to the air-launched MB-1 – to engage incoming Soviet bombers. During the early 1950s, before the emergence of ICBMs, the USAF expected the main nuclear threat to the United States to come via massive attacks by Soviet long-range bombers carrying atomic bombs.

The USAF hoped that weapons like the BOMARC and the MB-1 would be able to engage and neutralise large soviet formations before they reached their targets. This would be achieved by USAF interceptors scrambled to meet the incoming Soviet aircraft, the interceptors would move into engagement range and launch their MB-1 missiles, turning away to avoid the blast. The Genie would detonate inside or near the Soviet formations breaking up their attack. For this role, attacking massed enemy aircraft, the Genie certainly appears to be an efficient weapon concept. However, like the BOMARC it quickly became obsolete as the Soviets moved away from strategic bomber aircraft and embraced long-range intercontinental ballistic missiles.

BOMARC Site No. 1 at McGuire Air Force Base (USAF)

Development of the MB-1 was carried out by the Douglas Aircraft Company. Physically, the plump-looking air-to-air nuclear rocket was 9ft 2in long and 17.5in in diameter, weighing in at just over 820lbs (372kg). The weapon had four fins, which spanned over 3 feet, these deployed once launched and helped to stabilise the Genie’s flight.

The Genie carried a 1.5-kiloton W-25 nuclear warhead and was powered by a solid-fuel rocket engine developed by Thiokol. It could reach speeds up to Mach 3.3 and travel just over 6 miles before detonating. It’s effective blast radius was estimated to be just short of 1,000 feet (300m), the Genie relied upon this area effect as guidance systems small enough to be fitted to a missile were in their infancy, as a result the Genie was essentially an unguided rocket with no onboard guidance.

An Northrop F-89J has the distinction of being the only aircraft to fire a live MB-1 Genie during the Operation Plumbbob tests on 19th July, 1957. The F-89 was flown by Captain Eric W. Hutchison, with Captain Alfred C. Barbee acting as Radar Intercept Officer. They launched the Genie at around 18,500 feet, the nuclear-tipped Genie accelerated to Mach 3 and travelled 2.6 miles in less than 5 seconds. While operationally the weapon would have detonated by a time-delay fuse the Plumbbob detonation was triggered by a signal from the ground.

Test shot John was a form of controlled human testing, with not only those on the ground, beneath the blast tested for radiation dose sizes but also the crews of the aircraft that launched the rocket. This contemporary film about the test notes that “neutron and gamma doses for the three crews did not exceed 5 Reps and 3 Roentgens respectively.

A later report noted:

“Neutron and gamma radiation dosages received by the crew members were less than had been predicted. To some extent this may he attributed to the effect of aircraft shielding. which was not utilized in the theoretical predictions. No crew member received more than 5 Reps neutron and 3r gamma during his participation. The experiment proved that the MB-1 air-to-air rocket can be successfully launched by the F-89 aircraft at 19,000 feet MSL with a radiation dose to the delivery crew within acceptable limits.”

The yield of the explosion was estimated to have been 1.7 kilotons. 18,500 feet below, at ground zero, five USAF officers and a photographer volunteered to stand under the blast to prove that the weapon was safe for use over populated areas. The radiation doses received by the F-89 crew and the men on the ground were reportedly small.

The MB-1 became the primary air to air weapon of the F-106 Delta Dart, this footage includes and illustration showing how the MB-1 was deployed from the F-106 as well as some of the live missile tests with inert missiles during the development of the Delta Dart’s launch system for the Genie.

Douglas built more than 1,000 Genie rockets before terminating production in 1962. In June 1963, the MB-1 Genie rockets were re-designated in the AIR-2 and later the ATR-2A. The USAF’s operational deployment of the Genie ended in late 1980s with the retirement of the last F-106 Delta Darts. The Genie’s other operator, the Royal Canadian Air Force, continued to operate the Genie aboard until 1984.
