The M16 rifle had been a mainstay of the US infantryman for the best part of three decades. Developed from the Armalite AR-15 – itself in turn a redevelopment of the Armalite AR-10. Whilst a good rifle for its day, the normal infantry squad was always looking for more firepower, but from a lighter weapon. With this in mind, the designer of the AR-10, Eugene Stoner, took the idea of giving his new rifle more firepower from a chute feed system.
The chute feed system was not a new concept. It had been used on the .50 calibre waist gunner positions of the B-17 Flying Fortress during WWII. It was primarily designed for heavy machine guns rather than lighter squad weapons like the .303 calibre Browning then in use. This weapon was a standard belt fed machine gun but Stoner thought if his new rifle could give more firepower from its lighter weight, he would be onto a winner. He therefore set about redeveloping his own design from a standard box feed rifle, into a chute feed squad weapon. An adaptor was designed to fit on to the side of the AR-10, along with a bi-pod for greater stability when in use. The bullets would be fed down the chute from a magazine box carried on the back of the soldier.
Extensive testing with various sizes of cartridge, ranging from .223 inch (5.56mm) to 7.62mm (0.3 inch) proved promising, but the US Army didn’t seem interested and the idea fizzled out. Undeterred by this lack of interest Stoner moved to firstly to Colt and then onto Cadillac Gage, where he designed a modular weapons system, designated the Stoner 63. This system was configured to be a standard automatic rifle but, with slight changes, could be transformed into a light machine gun, a medium machine gun, or a solenoid-fired fixed machine gun for use on vehicles.
Some ideas for wargamers and modellers
As I can find no data regarding rates of fire or wear and tear on the barrel from sustained use, I suggest you use data based upon the Browning .303, if you wish to incorporate this weapon into your armies. As for modelling this weapon in the usual 10, 20 and 25mm ‘scales’, it should be fairly easy to convert a standard M16 armed figure. As you can see from the photos a simple bi-pod made from a folded paperclip glued to the front of the rifle should suffice. The back-pack ammunition box could be made from a converted Browning .303 ammunition box, but the chute feed system might prove a bit more tricky. One suggestion is to use an elastic band, cut to length and sprayed either with a primer, or dipped in diluted white glue, to add some strength. Another suggestion would be to use a laminate of wine bottle type foil caps and bend until you get the desired curves for the chute. Whichever way you do it, I hope this article has given you a new idea for a squad based weapon for use in your M16 armed forces.

They say that necessity is the mother of invention and this phrase is never truer than during wartime. As World War II progressed, armoured vehicles evolved to become more resilient to improving anti-tank weapons. Conversely, as tanks became better protected, newer ways had to be found to penetrate and destroy them. Anti-tank guns became larger in calibre and the shells heavier and more costly to produce. Many nations started to look at alternative ways to counter these more heavily armoured vehicles, whilst also controlling the cost of producing these counter measures. A range of hand-held or man portable weapons started to roll off the production lines of both the Allied and Axis nations. The Americans developed the Bazooka, the British the PIAT, (Projector, Infantry, Anti-Tank) and the Germans came up with the Panzer Faust single use launcher. Whilst all these weapons could be effective against a large target vehicle in the right conditions, their short range would often be their downfall. One potential solution was the development of rocket propelled projectiles and one country which came up with an effective design was, perhaps surprisingly, Hungary.
was, however, no stranger to designing and developing its own range
of military hardware. It produced reasonably effective Armoured
Fighting Vehicles, such as the Toldi and Turan, and its motor
industry also had a range of sturdy vehicles e.g. the Raba 38M
Botond. Unfortunately the Hungarians were seen by some officers in
the German High Command as being an unwilling and sometimes
unreliable ally. This meant that weapons development and technology
wasn’t always shared – including rocketry.
arrival of the T-34 and KV-I on the Eastern Front battlefields came
as a shock, not only to the Hungarians, but also to their German
allies. Being denied access to newer designs of anti-tank guns, the
Hungarian military had to look inward and turned to home grown
designs. With little or no help from their ally in counteracting the
threat of Soviet armour dominance, the Hungarian Institute of
Military Science (HTI) began its own anti-tank rocket development
program in 1942. After two years of designing and testing, it
produced the 44M Buzoganyveto
(literal translation ‘Mace Thrower’ – as the rocket head
resembled a mace seed pod).
rocket projectile was similar in appearance, although much smaller,
to the later Stuka zu Fuss rockets. Its total length was 1100mm with
a tube diameter of 100mm. Its warhead diameter was 250mm with a
length of 410mm. Two
types of rocket were designed for infantry use. One was for use
against armoured vehicles, the other, against troops. The anti-tank
version of the rocket was called ‘Buzogány’ (mace) and the
anti-personnel, high explosive type was called ‘Zápor’ (rainfall
or shower). The first prototype of the Buzogány was tested in the
spring of 1944. The rocket was 215mm in diameter (I assume this to be
the internal diameter of the explosive warhead) and contained a 4 kg
shaped charge. Designed to be able to penetrate more than 300mm of
armour or concrete, this rocket was able to destroy any kind of known
heavy tank of that time at a distance of between 500 and 1200 meters.
I assume here that the anti-tank version was a direct fire weapon but
it is unclear whether the anti-personnel rocket was capable of use as
an air burst weapon or whether it would just explode upon contact
with the ground.
A three man crew operated the rocket launcher with a gunner/aimer lying or sitting to the left of a protective shield with two loaders to his right hand side. The launcher designed initially for the 44M Buzogányvető was to be a conventional tripod arrangement, but this proved hard to move in a fluid battlefield situation. The solution to this issue presented itself when the upper part of the launcher (the two rockets and the protective shield) was mated to a Soviet wheeled Maxim machine gun mount, plenty of which had been captured earlier in the war. This arrangement made the Buzogányvető easier to manoeuvre.
Main features of the 44M Buzogányvető rockets
Length without rockets – 970mm Launcher tube length – 523mm Launcher tube diameter – 100mm Rocket head diameter – 215mm Weight – 29.2kg Rocket head weight – 4.2kg Range – 500-1200m. Maximum – 2000m Penetration – approx. 300 mm Crew – 3
Operational use of the 44M Buzogányvető rockets
Records vary as to how many launchers were actually produced but sources claim somewhere around 600 to 700. Due to the rapid advance of the Soviet armies during 1944, the Buzogányvető system was never used against its intended target i.e. Soviet heavy armour. The launchers were manufactured in the WM Factory and none seem to have been sent to frontline troops. The factory was over-run in December 1944, when Soviet troops captured it, and nearly all the rocket launchers were deployed and used in the siege of the Hungarian capital, Budapest.
Had this rocket system been designed earlier, it was envisaged as either simply a ground launcher or mounted in vehicles like the Krupp Protze, Opel Blitz or Rába Botond flatbed trucks. At least one was trial mounted on a Toldi II light tank.
Modelling the 44M Buzogányvető launcher and its use in wargaming.
When I first started to research this article, I never thought you would be able to buy a 44M Buzogányvető launcher or the rockets for it but a Google search shows that there are 3D printed versions of the wheeled launcher in various scales. A number of the commercial 3D printing companies make them in 1/100th, 1/72nd and 1/56th scales and no doubt you would be able to order them in any scale you prefer to game in.
As for their usage…well this would have opened up a whole new dimension to Eastern Front games if they had actually been deployed in time. The basic data for the rockets is included in this article so if you like adding a bit of ‘what if’ to your games, then this weapon system might be useful to you.
I have used Google extensively for this article. I have no personal connection with Google at all, I just prefer it as my main search engine. If you would like to see more, type in something like;

Le Gloan was from Brittany, born in the Breton town of
Kergrist-Moelou on 1 June 1913. He joined the French Armée de l’Air
in 1931, as soon as he was old enough to enlist. Before his death in
1943, he achieved Ace status (five kills) in the French Air Force
twice — before and
after France’s surrender (under the collaborationist Vichy regime).
With 18 kills to his name, France’s fourth highest-scoring ace of
World War II remains the only pilot in history to become an Ace on
opposing sides of the same conflict.
When war came he was flying a Morane-Saulnier MS 406 and, on 23 November 1939, he claimed his first kill, a Dornier Do 17 reconnaissance aircraft. A second Do 17 fell to his guns on 2 March 1940.
Gloan’s squadron were then re-equipped with the newer and better
Dewoitine D 520. Le Gloan (in plane number 227) lost no time in
taking full advantage of the better fighter. During the Battle of
France in the summer of 1940 he had a hot streak. In June, he shot
down two German Heinkel He 111s and two Italian Fiat BR 2 bombers.
The highlight of Le Gloan’s career was to come on 15 June. His
squadron encountering a squadron of Italian CR 42 fighters, he
attacked with enthusiasm, shooting down no fewer than three of them.
On his return to base he came across another CR 42 and a BR 20. He
attacked and shot down both of them.
down five aircraft in one day has seldom been achieved by even the
highest-scoring fighter Ace and Le Gloan was justly rewarded. His
five-kill streak brought him up to 11 kills, well above the five
required for Ace status. He was also promoted to 2nd Lieutenant to
acknowledge his remarkable feat.
20 June his squadron was transferred to Algeria and, with the fall of
France and the installation of Marshal Petain’s Vichy government, the
French forces in North Africa were under Vichy command.
His squadron was transferred to Syria and in June and July of 1941 took to the air to defend the colony from the British Le Gloan shot down six of the RAF’s Hurricane fighters and a Gloster Gladiator bi-plane. In Syria his plane No. 277 was lost after a bad landing caused by combat damage. He had taken down 11 for France and had added another seven for Vichy. At the war’s end only Jean Demozay (21 kills), Marcel Albert (23 and two probables) and Pierre Clostermann (33 kills) ranked higher among French aces.
The Allies launched Operation Torch in November 1942, invading Vichy controlled Algeria and Morocco. After just a couple of days the French forces returned to the Allied side, including Le Gloan’s fighter squadron. The squadron was re-equipped in May 1943 with American Bell P-39 Airacobras, newly promoted Capitaine Le Gloan flying one of them. Unfortunately on 11 September, whilst on a training flight, Le Gloan’s aircraft developed engine trouble and he was forced to return to Algiers. Attempting to belly land his failing craft he forgot about the belly tank which Airacobras carried to extend their range. This tank should have been jettisoned before any attempt to land was made. This lapse led to the plane exploding upon impact killing le Gloan instantly. He was 30 years old.
The Winter War between the Soviet Union and Finland began with the Soviet invasion of Finland on 30 November 1939. Thinking the Germans were his new friends (and weren’t going to attack him) Stalin turned his eyes towards Finland. Just three months after the outbreak of World War II, Soviet forces crossed the Finnish border hoping for a Blitzkrieg of their own. The Finns, however, had other ideas. The war raged for three and a half months but, following an initial setback, the Soviets’ overwhelming numbers (and change of tactics) won through in the end. The war ended with the Moscow Peace Treaty on 13 March 1940 by which the Soviets conceded Finland’s independence in return for some territorial concessions.
the relatively peaceful period thereafter the Finnish Armed forces
began to reorganise and to re-arm. When Nazi German forces invaded
the Soviet Union in June 1941, Finland saw an opportunity to strike
back to reclaim the territory lost earlier. The Finns were now
equipped with many captured Soviet vehicles and weapons, via their
German co-belligerents, along with others obtained from Sweden. They
did not, however, have sufficient vehicles to move them all – the
heavier artillery and anti-tank guns taking priority. So, it was back
to the drawing board in addressing the issue of tows and their
solution was quite a simple one – horsepower.
Having been supplied with some Bofors M-38 37mm AT guns from Sweden and quite a lot of captured Russian Model 1937 45mm AT guns, the Finns designed a simple harness arrangement to be adapted for each gun.
In total, the Finns received several hundred captured Model 1937 guns from the Germans, although not every gun was able to be brought back into service. In terms of standardising the means of transportation, and minimising its cost, the Finnish armed forces seem to have come up with a novel approach. All these pictures were taken in the ‘research and development’ department in the military citadel of Helsinki in February 1944. Whether these adaptations were ever used is not documented.
Some ideas for modelling
the popular scales of 10, 15, 20 and 25mm it should be possible to
make something similar, if not an exact replica, of the two harnesses
shown in the photographs. As can be seen from the Bofors M-38 photos,
the apparatus is simply two parallel bars with two attached cross
braces and a seat for the driver. This could easily be replicated
with plastic rod and card.
The harness for the Soviet Model 1937 seems to be an elongated ‘U’ shape. Again, this could be fabricated from plastic rod gently heated and bent to shape or from a piece of wire, shaped around a suitably sized tube. The seat poses more of a problem as it appears to be some kind of tractor seat. As for the riders/drivers, the one sitting ‘side saddle’ on the Bofors gun would be harder to re-create but the one on the Model 1937 gun could come from a horse rider with his saddle still attached. And if you really want to ‘mix it up’ why not replace the horse with a reindeer and the driver with a winter greatcoat and steel helmet.
I hope this article has given you some inspiration to add something different to your Finnish forces for your Winter War/Continuation War scenarios.

It’s really quite interesting but, although the website is available in English, searches can be conducted only in Finnish. Finnish is a notoriously tricky little devil (what with being unrelated to all the European languages with which most of us will be even a little familiar) and this does lessen its ease of use. Worth a browse though.
In the dark days of September 1940, Britain and the Commonwealth stood alone. The Nazis occupied most of Europe, the Japanese were on the offensive and had the upper hand in the Far East and even Egypt and the Middle East weren’t safe. Fear of invasion from Italian forces in North Africa had stretched the British Army to breaking point. The fiasco that was the rout at Dunkirk had had a positive spin put on it by politicians and was made to be seen as a victory. In reality, it was a defeat — most of the modern tanks, vehicles and heavy weapons that had gone to France with the BEF had been left behind. Prime Minister Winston Churchill called for action but what action could the country take when so thoroughly on the back foot? Then on the night 17/18 September 1940, Britain conducted a stealth raid into occupied Europe. A raid so stealthy, they didn’t know they had done it!
winds had broken loose a number of barrage balloons from their
moorings. These balloons drifted across the North Sea and (crash)
landed in Denmark and Sweden. The sturdy steel cables trailing from
the balloons caused damage to power lines, careered into railway
traffic and collided with the antenna of the Swedish International
radio station, causing it to go offline for a while. Five balloons
(but maybe more) were reported to have drifted as far as Finland.
many balloons had ‘escaped’ was never reported but upon hearing
the news of the damage and confusion they caused, Churchill was
jubilant. He reasoned that if such a low cost ‘weapon’ could do
this, then a further, more detailed study should be taken with a view
to doing something along the same lines…but deliberately.
In fact the matter had already been investigated a few years earlier. The British Air Ministry had begun producing barrage balloons as far back as 1936. Forward thinkers had seen the war clouds gathering so in 1937 the Air Ministry conducted a study to determine how much damage a balloon could cause if it broke free from its mooring and its steel cable was dragged across the countryside. The study showed that, if the steel cable were to short out power lines, electricity supplies would be out for at least six hours. This study had been undertaken as a Civil Defence measure — to determine how long people and industry would be without power in the event of an accidental balloon drift over Britain. The use of barrage balloons as an offensive weapon had not been considered — until Churchill became involved.
the Air Ministry opposed it on the grounds that the balloons would
interfere with flight operations. Friendly balloons floating about in
the darkened skies might become entangled with RAF aircraft. It also
argued the point that these balloons were unguided and uncontrollable
and any success would be more by chance than design. Retaliation in
kind by the Germans from the occupied coasts of Europe could not be
ruled out either.
In contrast, the Admiralty Board was more open to the idea, arguing that it was a ‘cheap and cheerful’ way to strike back at the enemy. Comparing the cost of a balloon to a front line bomber was persuasive and, as there was also an ample supply of hydrogen gas for the balloons, the program started in earnest. Meteorological studies had shown that more winds blew from Britain towards the continent than blew from the continent towards Britain. In an average year the prevailing wind was west to east 55% of the time and only east to west 38% of the time. This made the idea of German retaliation highly improbable and probably less effective if implemented. More importantly an engineering study had shown Germany’s power grid was considerably more vulnerable to damage by short-circuit than the British system. Coupling this with the fact that large pine forests (which were considered more vulnerable to incendiary attacks than British hard wood forests) covered many parts of the German heartland and continental Europe, the program was begun. However, as with all things involving two branches of the British military a long, bureaucratic struggle between the Air Ministry and the Admiralty began. The programme was held up until September 1941 when the go-ahead was finally given: Operation Outward would commence.
The Balloon Goes Up
first launch site was Landguard Fort south of Felixstowe situated in
a remote southern part of Suffolk. Originally built as one of a
string of Napoleonic Forts for home defence, it was situated at
the mouth of the River Orwell. Designed and built over a century
earlier, its purpose was to guard the entrance to the port of Harwich
(and the surrounding area) from the perceived Napoleonic invasion
threat. An old imposing structure with high, thick walls, it would
be able to store the balloons and their associated equipment, whilst
keeping prying eyes at bay.
Following detailed studies and tests of balloon designs, two types of balloon were to be used. The first type was a typical eight feet round weather balloon modified to carry three six pound incendiary ‘socks’. These socks were designed to set fire to pine forests and heathland. A second balloon tested was similar to, but not as large as, a standard barrage balloon. This smaller barrage balloon would trail a long steel cable which, it was hoped, would hit power lines and create a short circuit. Tests were conducted on the balloons regarding duration of flight and with a timed ‘burn fuse’ attached. This saw their ceiling height set at about 16,000 feet, give or take a few hundred feet for wind and other atmospheric conditions. Natural leakage of the hydrogen gas from the balloons, along with a timed deflation valve obviated the need for any ballast or pressure-control systems to control and maintain altitude. As the Spitfire fighter and Lancaster bomber could fly in excess of 20,000 feet, the balloons should not interfere with any normal RAF flight operations.
the balloons simple and easy to operate, no expert crew had to be
employed in their usage. Fighting men could be freed up and used
elsewhere so the role of balloon handlers fell mainly onto the
shoulders of the WRNS (Women’s Royal Navy Service) or WRENS (as
they were commonly called). These personnel were supervised by a few
(male) NCOs and technicians! A detailed plan for launching the
balloons was introduced so as not to conflict with either incoming or
outgoing RAF flight operations. Times were set for balloon launch
operations but these could be changed if RAF aircraft were grounded
due to bad weather. The balloons could fly even if the aircraft could
first launches took place on 20 March 1942 and, within a few days,
encouraging reports of forest fires near Berlin and in East Prussia
were received. Radio intercepts showed that the Luftwaffe was sending
up fighters to try to destroy the balloons. This was very encouraging
news to both Churchill and the combined RAF and Admiralty operation.
It would appear that the Germans were spending far more resources
trying to destroy the balloons than the British were by launching
them. Sending up fighters to try to destroy the balloons meant they
were using extra fuel, putting more strain onto airframes, increasing
aircrew fatigue etc. Whilst the Germans did their best to intercept
as many balloons a possible, they soon realised they were fighting a
Reports from French Resistance cells and other, neutral sources claimed that the balloons were causing a lot of disruption to rail, road and agriculture operations and services. These encouraging reports reached the ears of the French Government in exile in London, and they wanted more released to help tie down enemy forces.
The balloon operation had proven successful — for very little outlay a lot of disruption had been caused. These initial successes led to two other launch sites being set up in April and May 1942. One site chosen was on the coast at Oldstairs Bay between Dover and Deal in Kent, the other being Waxham in Norfolk. The latter site was an isolated coastal village north of Great Yarmouth. These sites brought anywhere from Northern France to Scandinavia within a balloon’s sphere of operation with a good wind blowing to the continent.
Success for the Balloons
the balloons proved to be an economical way to strike back at the
enemy in the short term, they were never intended to be a realistic
military weapon to cause mass damage or destruction. Their launch was
seen as being of a nuisance value. Although they did tie up a lot of
enemy manpower resources, in reality they caused very little military
damage. People in the higher chain of command began to doubt that
the effort put into this operation was worth it. However, the night
12 July 1942 began to change a some minds. A cable-trailing balloon
struck a 110,000 volt power line near Leipzig. The overload switch in
the nearby Bohlen power station did not trip quickly enough and this
resulted in a fire which spread and destroyed the entire complex. The
damage was estimated at £1,000,000 compared to the £220,000 spent
on Operation Outward.
August 1942 up to a thousand balloons per day were being released,
weather permitting. The Germans were now tied up fighting in the east
and the balloons seemed to have free rein over the skies of occupied
Europe. Some reports even state they reached as far as Hungary. The
German military were engaged in fighting in the Soviet Union leaving
it to the German civilian services to try to fight the ‘balloon
war’ on their own.
The balloon offensive had proven a success but this success did come at a price. On the night of 19/20 February 1944 a cable-trailing balloon shorted out a Swedish overhead rail lighting system. This short circuit of the system resulted in a collision between two trains. The number of people injured or fatally wounded was never revealed but a diplomatic protest was issued by the Swedish government. Other than to say sorry and perhaps compensate a neutral country for any material loss, there was little the British government could do. This unfortunate incident did prove without doubt the potential of the balloon campaign, raising the question of how much damage wasn’t being reported by the German authorities.
End of Operations
With the tide of the war turning in the Allies’ favour and having achieved virtual air superiority over occupied Europe, it was decided that the number of balloons being released should be cut back. From May 1944 a change of tactics was also implemented. Mass balloon launches were stopped and replaced with a trickle of balloons launched from the three sites at ten-minute intervals throughout daylight hours. Only 2% of these balloons were to be of the trailing wire type — a type which could have caused major damage to allied aircraft. The remaining 98% carried of incendiary bombs. Cutting back on balloon launches increased the availability of hydrogen gas for use elsewhere and freed up much-needed transport vehicles and compressed gas cylinders ready for the planned Normandy landings. With the success of the D-Day landings on 6 June 1944 and with the Allies making gains into Occupied Europe the last offensive balloons were launched on 4 September 1944.
Further Research and Reading
Thanks to something Alan Hamilton said on the SOTCW Forum I set off to research this unusual operation. Using Google as my first port of call most of what I have written here is gleaned from various sources online. There is still a lot of technical, detailed information about Operation Outward that I haven’t included. I haven’t set out to write a complete history of the Operation but just to give the reader a taste of something unusual that happened in the darkest days of WWII. It would be advisable to read this article in conjunction with online maps and images of the locations mentioned. That way (hopefully) you’ll be able to see how remote and secretive the chosen balloon release sites were. I hope you enjoy it.

The T-12 was developed as a replacement for the D-48 85mm anti-tank gun, and was the first smoothbore anti-tank gun to enter service, in 1961. The decision to adopt a smoothbore barrel led to improved HEAT performance, higher muzzle velocity, and longer barrel life than an equivalent rifled barrel. The kinetic energy penetrator was very long and thin, further improving penetration.
Production of an improved version, the MT-12 (also known to NATO as the T-12A), began in 1970. This had a new improved carriage, which was less prone to turning over whilst being towed. Both models had sights for indirect fire and direct fire, but indirect fire range was limited by the maximum elevation of only 20º. The T-12 was normally towed by a lorry, the MT-12 by an MT-LB.
The crew of six consisted of commander, towing vehicle driver, gunlayer, loader, and two ammunition numbers. The barrel had a perforated muzzle brake, and was clamped to the trails when in transit. The loader had to open the breech manually to load the first round, after which a semi-automatic loading system would open and close the breech, so that the loader only had to load shells. Image intensifier night sights were fitted. A shield gave the crew some protection from small arms fire and shell splinters.
The T-12 and MT-12 both fired APFSDS, HEAT, and HE ammunition. The APFSDS round had penetration of 230mm at 500m, 140mm at 3,000m. The HEAT round could penetrate 350mm. From 1981, the MT-12 was able to fire the new AT-10 Stabber laser beam-riding ATGM, which had a maximum range of 4,000m and penetration of 550mm. The laser designator was mounted on a tripod to one side of the gun.
The MT-12 was the last towed Soviet anti-tank gun to enter production. Development began of a 125mm towed gun, the 2A45 Sprut, but this never entered production.
The Quarterly Newsletter of ‘The Ordnance Society‘ has been carrying a series of short four or five page illustrated articles on Imperial Japanese weapons of WWII, at least the more unusual ones. In Numbers 116 and 117 the suicide ‘lunge-mine’ and the incredible 70mm anti-aircraft barrage mortar are featured (I made one of the latter following C.O. Ellis’ brilliant, instructive articles in Airfix Magazine over fifty years ago). The most recent issue deals with a weapon I had never heard of — Japanese cyanide grenades. The series, written by Peter McAllister, is excellent and is set to continue in future issues. As a wargamer I find the content intriguing and valuable – something to be aware of if you field an Imperial army of the period.
The 70mm Anti-Aircraft Barrage Mortar (7cm Uchlaqe Sosoku-Dan)
During the history of warfare many combatants, from all periods, came up with ideas that worked far better in theory than they did in actual reality. The Imperial Japanese Army (IJA) during WWII was no exception. One of the many ideas the weapon designers of Japan came up with was a rather clever type of anti-aircraft mortar. A surprising amount of thought went into this weapon, available in two calibres, 70mm and 8lmm. I will take a look at the far more common example, the 70mm design.
The IJA had a fairly sophisticated array of anti-aircraft weapons, aiming systems and detection devices. Why they thought, then, that they needed something as strange as an anti-aircraft mortar is, at first glance, a bit of a mystery. However, at closer inspection it can be seen that there was a strange current running through at least some of the IJA’s weapon design process. One only has to look at the hopper fed Type 11 light machine gun or the mass of (mostly unused) accessories that came along with some manufacturing runs of the Type 99 rifle. And let’s not even discuss the unneeded design of the Type 2 paratrooper rifle. Each of the above examples has something in common with the 70mm anti-aircraft mortar. In theory, they were good ideas but in practice were at least an irritant to the user – if not worse. In short, the IJA infantry’s having a light anti-aircraft weapon on hand in all terrain was a good idea but making that weapon a mortar? Not so much.
The 70mm version of the anti-aircraft barrage mortar was made (starting in 1942) at the Number 1 Army arsenal in Tokyo. As this arsenal already made 70mm mortar barrels for more conventional mortars, presumably the same facilities were used for the barrage mortar. The idea was that the mortar would discharge its projectile which, at its maximum ceiling would eject seven smaller projectiles. Connected to small parachutes these would detonate on enemy aircraft flying at low altitude. To be effective mass barrages would be needed but, despite the fairly widespread issue of the weapon, its use in its intended role was rather ad hoc. It seems that improvised platoons were its most common form of deployment. One such platoon in the Philippines had 31 men operating a mere five devices. What such an under-strength unit was supposed to achieve is anyone’s guess.
The mortar had a smoothbore barrel that was 48 inches long. The barrel was connected to a wooden block described in an American intelligence document of December 1943.
‘The base of the 70mm barrage mortar is a wooden block approximately 10 by 12 by 8 inches. Two bolts fasten a small base plate to the block. The wooden block absorbs the shock of firing and prevents the mortar from embedding itself in the ground’
A later American intelligence document, from March 1945 confirms much of what was written in the 1943 document,
‘The Japanese 70mm barrage mortar was first encountered on Attu. It consists of a smoothbore tube, 4 feet long, the steel plate of which is fastened by two bolts to a wooden block…’
The overall length is 75 inches. At the bottom of the wooden block is a long iron spike. The weapon is prepared and pointed toward the enemy aircraft by embedding this iron spike into the earth. Thus it can be seen that aiming was rather crudely done. The previously quoted document from 1943 simply says,
‘the 70mm or 81mm tube had no settings, controls or adjustments.’
This is a simple and, no doubt, cheaply made weapon. To fire the weapon the projectile was simply dropped down the barrel. If the round failed to fire the whole weapon would be slowly lifted up and gently tilted forwards to allow the round to slowly slide out. As for the projectile, it was as inventive as anything else devised during the war. It’s just a pity (at least for the IJA) that this inventiveness failed to find a better outlet. The same American intelligence document from December 1943 has a good description of the ammunition, presumably examples taken at Attu.
‘Ammunition for the 70mm barrage mortar is packed 10 to a box. The shell contains 7 parachute bombs 3 inches long by 11/16ths of an inch in diameter. A steel cylinder encases the whole assembly. The shell is painted black and is 11 9/16ths inches long and 2.34 inches in diameter. The nose is capped with a wooden disk. After the shell is projected from the mortar by the propelling charge in the base, a time train and fixed powder charge cause the projection of the seven smaller bombs borne by rice paper parachutes. At the same time a larger parachute is opened – tilting the main container and thus ensuring the scattering of the seven bombs.
These small bombs are loaded with three pellets of nitrostarch and are detonated in the air by a sensitive pull-igniter fuze with a phosphorus-coated string and delay element. They may also be used as an effective booby trap for any curious or unwary soldier.’
Again, the later American intelligence document from 1945 confirms much of the earlier intelligence document’s observations with one bonus – the 1945 document includes actual American test information.
‘Five rounds have been fired in a test, with the mortar malfunction of the delay train ignition (ed. – sadly, this is not elaborated on). The shells were quite noisy in flight and tumbled considerably, with the smoke of the black powder delay train clearly visible.
The releasing burst occurred in 7 to 8 seconds at altitudes of 1,520 to 1,660 feet and the shell cases hit the ground close to the firing position. All inert components of the round drifted to the ground within 30 seconds and the bombs drifted nearly half a mile, landing at intervals of about 30 yards.’
An example of a projectile for the barrage mortar that came up for sale some years ago (2007) was painted black with two white bands at the forward end and a red band at the other. The inside of the casing bottom still had some coiled fuse in place. The black painted projectile had a number of markings. On one side was a roughly applied area of white paint, almost a smudge, on which, in black, was the Kanji for ‘east’. The other side had a seven stage, top to bottom, series of Kanji symbols. While this is not an exact they, from top to bottom, translate as ‘seven, military measurement, together, launch, to block(?), to protect the fortress and bullet.’ As noted this may not be an exact translation. Other technical data differs from that already given. At least one modern claim says that the explosive component was RDX and the booster was lead azide. Of course, it’s very possible different types of explosive were used at different times.
It seems that the projectiles could also be fired more conventionally from the standard IJA model 11 70mm mortar. Though it is obscure as to what effect that tactic had on the battle field. Very oddly there is at least one eyewitness case of the barrage mortar being mounted in a Japanese bomber for defence against allied fighters.
The rice paper parachutes were around a foot in diameter, perhaps in some cases a bit larger. It is also clear that black powder could be used instead of the more usual ignition sources. As for maximum range, one American report gives the fairly unlikely number of 4,000 feet. Between 1,000 and 2,000 feet was far more realistic.
The blast radius, despite the small charge of the individual bomblets was around a 10 to 20 yards radius.
Stripping the 70mm barrage mortar was easy. First the barrel was unscrewed from the metal base plates, thus separating it from the wooden base block. The firing pin might then be removed from the fitting that holds it to the base plate. Finally the iron spike is removed from the wooden block.
On a last note, a May 1944 American intelligence report is fairly blunt about the weapon’s prospects in battle,
‘Although no instance has ever been reported of our aircraft being damaged with this weapon, it would appear that this weapon might be very effective against low flying aircraft if used in sufficient quantity.’
As previously noted however, these weapons tended to be used in penny packets. The fact that those issued with them sought to find other uses for the projectiles speaks for itself. In short the 70mm (and 81 mm) anti-aircraft barrage mortars must be considered interesting failures. Before those of British heritage become too smug however, a similar British project did catch the eye of Winston Churchill. Thankfully, cooler heads made sure it came to nothing.
Terror in the capital – London Street under siege!
Picture the scene: armed terrorists are holed up in a London street tenement block. Police and soldiers have been called upon to break the deadlock. The Home Secretary is in attendance to witness the outcome. Crowds gather on the street corners as cameramen from a major news company record the unfolding events.
Sounds like something you might see on the nightly news today doesn’t it? But this was London 3 January 1911. It was The Siege of Sidney Street, or as some call it, The Battle of Stepney!
The incident that took place on that fateful day can be traced back a little over two weeks earlier, to the night of 16 December 1910. On that night at around 10pm Max Weil, resident of 120 Houndsditch Road, arrived home to find his sister and their housemaid in a state of mild panic and alarm. They could hear sounds coming from the jeweller’s shop next door at 119 and they assumed someone was trying to break in from the rear of the premises. The jewellery shop was owned by Henry Samuel Harris and it was believed the safe inside it may have contained between £20,000 and £30,000.
After calming his sister and the housemaid, Max set off to the local police station at Bishopgate but came upon a Constable Piper doing his rounds. Max told him what he heard so the constable came to investigate. The property in Houndsditch Road backed onto a neighbouring street and they were separated only by a small yard. The gang who were trying to rob the jewellers had rented 9 and 11 Exchange Buildings but they couldn’t rent 10 for some reason (see photograph below).
They were living in 11 and using that as a base of operations but it was from 9 where they would gain access to the jeweller’s shop. Constable Piper checked the premises of 118 and 121 Houndsditch Road,from where he could hear the noise. Finding nothing amiss at those premises, he went around the corner to the Exchange Buildings, to investigate further. At approximately11pm he knocked at the door of 11 Exchange Buildings, as this was the only building with a light on. The door was opened by man who spoke little or no English. The police constable immediately became suspicious, so he decided the best course of action was to report in and summon help. Making his way back to Bishopsgate Police Station, Constable Piper saw two other policemen from the adjoining beats, Constables Woodhams and Choat, and he asked them to watch 120 Houndsditch Round and 11 Exchange Buildings, while he went to the nearby Bishopsgate Police Station to report what he had seen and heard.
He returned with three sergeants and another five constables. At approximately 11.30pm, two of the sergeants, Bentley and Bryant, along with Constable Woodhams, approached 11 Exchange Buildings and knocked on the door. Again, the door was opened by a man who spoke little or no English and Sergeant Bentley asked if anyone was working in the premises. The man didn’t seem to understand the question and the immediately subsequent events are unclear. Sergeants Bentley and Bryant, along with Constable Woodhams, somehow gained access to the premises. One version is the door was shut in their face, so they forced entry whilst another suggests that the door was ajar as the man went back inside the premises and they followed him. What is clear though is that shots rang out, and Sergeant Bentley was killed while Sergeant Bryant and Constable Woodhams were seriously injured (both were later invalided out of the Police Force).
At least three men and a woman were observed running out of 11 and the third Sergeant on the scene, Sergeant Tucker, was killed when one of the assailants opened fire again. Constable Choate managed to tackle one of the gang to the ground but he was callously shot in the back and died though not before the robber he had tackled, had himself been shot by his own gang mate.
Returning to their lodgings, the injured robber was left on a bed with a Model 1907 Dreyse pistol under his mattress. Whether this was to incriminate him in the murders of the police officers or to protect himself in case of arrest, we’ll never know, as he died of the wounds he had received. A doctor was called in the early hours of 17 December. Because he had not heard of the incident the night before he believed some cock and bull story about an accidental shooting from a friend. The doctor left, but returned later that day around 11am, to find the patient dead. Eventually the police found out the identity of the corpse — one George Gardstein — and raided the lodging house where he was resident. They apprehended one Sara Trassjonsky in the next room, burning papers and anarchist material. Whilst George Gardstein was an alias the authorities knew him as a Latvian anarchist and had an idea of the people they were now looking for.
Gardstein’s body was taken to a local mortuary where his face was cleaned, his hair brushed, his eyes opened and his photograph taken. The photograph and descriptions of those who had helped Gardstein escape from 11 Exchange Buildings, were distributed on posters in English and Russian asking for information about the robbers and police murderers. Information from a concerned public poured in and the police soon had a list of ‘persons of interest’ that they would like to interview about the robbery and the shootings. These persons were; Yakov (or Jacob) Peters, Yourka Dubof, Fritz Svaars, Peter Piaktow, William (or Joseph) Sokoloff, Karl Hoffman, (an alias as his real name was Alfred Dzirco), John Rosen, (real name John Zelin), Max Smoller, Sara Trassjonsky, Nina Vassilleva, Luba Milstein (Svaars’ mistress) and Osip Federoff. Most were arrested and tried but two remained at large -Sokoloff and Svaars. Peter Piaktow appears to be a figment of imagination as he was never tracked down or identified as existing.
On the 1 January 1911 the landlord of 100 Sidney Street contacted police to say that the two remaining suspects were lodging at that address along with a woman, Betty Gershon, believed to be Sokoloff’s mistress. The landlord was asked to return the next day, 2 January 1911, to confirm they were still lodging there. He returned and confirmed they were and on the afternoon of the 2 January the police formulated a plan to apprehend the two criminals.
Let Battle Commence!
In the early hours of 3 January 200 police officers (having been mobilized from both the City of London and Metropolitan forces), proceeded to cordon off the area around 100 Sidney Street. Armed officers were placed in 111, directly opposite 100, to keep a watchful eye, as their colleges in the street below began to wake the residents of the houses on the block and to safely evacuate the civilian population. The landlord of 100 woke the ground floor tenants and asked them to fetch Gershon, saying she was needed by her sick husband. She was grabbed by the police as she left the building and taken to the City of London police headquarters. The house was now empty of all residents apart from Svaars and Sokoloff, neither of whom seemed to be aware of the evacuation.
The structure of the building, with its narrow winding stairwell, meant any approach into the dwelling house during the hours of darkness, would be hazardous for the police. The decision was taken to wait until morning before making an attempt to apprehend the criminals. At about 7:30am a policeman knocked on the door. When there was no response, stones were then thrown at the window to wake the men. Svaars and Sokoloff appeared at the window and, realising who was knocking, opened fire at the police. A police sergeant was wounded in the chest and taken to the London Hospital. Some members of the police returned fire but being equipped only with short range shotguns and small calibre revolvers, their guns proved ineffective against the comparatively advanced automatic weapons of Svaars and Sokoloff.
An exchange of fire continued until about 9:00am when it became apparent that the two gunmen possessed superior weapons and ample ammunition for a prolonged siege. The police officers in charge at the scene, a Superintendent Mulvaney and a Chief Superintendent Stark, contacted the Assistant Commissioner, Major Frederick Wodehouse at Scotland Yard and said they would need greater assistance if they were to apprehend the two criminals. Major Wodehouse telephoned the Home Office and asked for, and was granted, permission to bring in a detachment of Scots Guards, who were stationed at the Tower of London. It was the first time that the police had requested military assistance in London to deal with an armed siege. The person who granted the request was none other than Winston Churchill himself. 21 volunteer marksmen from the Scots Guards arrived at about 10:00am and took up positions at each end of the street and in the houses opposite.
Not wishing to miss out on a good photo opportunity, Churchill arrived at the scene about noon. Up until that point sporadic shots from both sides had been made but the tempo then increased for about 30 minutes. At around 1pm smoke was seen coming from the building’s chimneys and from the second floor windows. It was clear that the building had caught fire but no one seems to know how it had started. Also by this time a second detachment of Scots Guards had arrived and they had brought with them a Maxim machine gun (which, in the event was not used). Sokoloff put his head out of a window and he was promptly shot by one of the soldiers. He fell back inside the room but it wasn’t known if he was dead or injured. A senior officer from the London Fire Brigade sought permission to extinguish the blaze but was refused. He approached Churchill in order to have the decision overturned but the Home Secretary approved the police decision to let the building burn, and so ‘flush out’ the terrorists.
Churchill later wrote:
“I now intervened to settle this dispute, at one moment quite heated. I told the fire-brigade officer on my authority as Home Secretary that the house was to be allowed to burn down and that he was to stand by in readiness to prevent the conflagration from spreading”
By 2:30pm, there were no more shots coming from the house. With the upper floors now firmly ablaze a police detective hugging the street walls for safety, approached and pushed the front door open before retreating back again along the street. Armed police officers, along with some of the soldiers, came out onto the street and waited for the men to exit. No one exited the building and part of the roof collapsed due to the fire. It would appear that the men were both dead so the fire brigade was allowed to start extinguishing the blazing building. At 2:40pm, as Churchill was leaving the scene, a detachment from the Royal Horse Artillery arrived with two 13 Pounder field guns. Who had ordered the guns, or even sanctioned their possible use on the city street, was never clarified.
When the firemen entered the property to douse the flames they quickly discovered Sokoloff’s body. Due to the intense heat of the blaze and, no doubt, poor construction of the building in the first place, a wall collapsed onto a group of five firemen. They were all taken to the London Hospital and treated for their wounds. One of the firemen involved in the building collapse, Superintendent Charles Pearson, had a fractured spine: He died six months after the siege as a result of his injuries. The firemen shored up the building and made it safe to enter. They resumed their search of the premises and at around 6:30pm a second body was discovered; it was Svaars…and so ended the Battle of Stepney.
Gaming this type of scenario
This type of urban clash/uprising could easily be gamed in the popular scales of 20, 25 and 28mm as there are numerous figures you could either use directly or adapt. In 20mm RH Models has a range of figures suitable for the Scots Guards in their Irish Wars range, whilst some adaptation of figures from Irregular Miniatures’ Very British Civil War range would give you the terrorists. In 25mm the older Airfix range, or possible newer HäT box sets, would give options for soldiers from their WWI British and Artillery boxes but some modification may be need. I’m not sure about 25mm civilians or armed police but maybe the police figures could be made from Colonial British figures with the pith helmet altered to represent a British Bobby’s hat? In 28mm the mass of figures from Reiver Castings in their Very British Civil War range would be idea, but this all depends upon your choice of scale. Buildings could really be any form of three or four storey tenement or shop but you would need a few to make up into the narrow, confined type of street that Sidney Street was. What rules you use, would depend upon personal choice.
I hope this article has give you some ideas to try something different and I hope you have enjoyed reading it.
