This I iron was used exclusively in the manufacture of the better firearms; and it may have been its very quality which was responsible for the establishment of a tradition in the production of fine arms antique gateleg drop leaf table . Instead of welding a flat piece of metal into a tube, the Spanish gunsmiths formed a barrel by twisting the metal george iv fabrics . A long flat strip of wrought iron was coiled round a mandrel, heated, and knocked together from the two ends till it formed a solid tube with a spiral weld 19th century english oak urn shaped double pedestal refectory table . An additional Spanish touch was to bore out the barrel to a slightly larger diameter at both the breech and the muzzle ends english early ‘victorian upholstered round . The object of this was to give the bullet more resistance, and hence increased power, at the start of its journey; and then to increase its velocity by giving it greater freedom of movement just before it left the muzzle antique china furstenberg . It seems doubtful whether this Spanish boring added anything to the efficiency of a very fine barrel antique pemproke tables .
The first guns with twist barrels to be made in England were naturally the expensive weapons which were made for private purchase by sportsmen; and this may have happened, J jean dunand fakes vases . N 19th century american rosewood rococo console table . George suggests, some time shortly after 175o painted china cabinets + pictures . The favourite source in England for iron of a suitable quality was the metal salvaged from old worn-out horse-shoe nails doric china/tea sets/longton . This, apparently, surprising choice was due to the fact that the nails for horse-shoes were made out of the best wrought iron obtainable; and were subsequently toughened by pounding over the rocky, boggy or dusty tracks which passed for roadways in the latter part of the eighteenth century antique paper-mache desk . The strips of metal which were produced from this material were twisted in the Spanish fashion; and from the origin of the metal this type of manufacture was known as ’stub twist’ 1920s antique oak refrectory dining table .
THE ARMY’S FIRST RIFLE
The brief appearance of rifled firearms in war has been mentioned in Chapter II painted slant front desk . But for a hundred years after the Restoration the British Army fought wholly with smooth-bore weapons tripod pedestal . It was not till the American War of Independence that British troops encountered rifles in the field, and a halfhearted attempt was made to redress the balance design contemporary dressing table .
In 1747 a remarkable paper was read before the Royal Society by one Benjamin Robins catherine the great of russia plates . It was entitled ‘Observations of the Nature and Advantage of Rifled Barrel Pieces’, and it forms the basis of current thinking on the effect and desigq of rifling british sideboards . Robins was Engineer-General to the Honourable the East India Company, and a very distinguished mathematician kuba rugs prayer .
He explained the difference between a smooth-bored and a rifled barrel in the following terms: ‘A common piece has its barrel smooth on the inside, whereas the rifled piece has its cylinder cut with a number of spiral channels: so that it is in reality a female screw, varying from the fabric of common screws only in this, that its threads or rifles are less deflected, and approach more to a right line: it being usual for the threads with which the rifled barrel is indented to take a little more than one turn in its whole length marquetry patterns flower . The number of these threads in each barrel are different, according to the fancy of the workman, and the size of the barrel; and in like manner, the depth these channels, or rifles, are cut down to is not regulated by any invariable rule, but differs according to the country where the work is performed, or the caprice of the artificer cabriole legs basin .’
Robins pointed out that the usual method of loading a rifle was, after inserting the correct amount of powder, to put a bullet on top of the muzzle which was slightly larger than the bore had been before cutting the rifling antique mahogany round table brass feet with drawer . The bullet was then hammered down with yammer and mallet setobody . He maintained, however, that the sole function of rifling was to spin the bullet, in order to neutralize its inevitable inequalities and thus keep it straight in flight george 11 pad foot dining table . It will be remembered that it was this same theory, on the analogy of the flight of an arrow, which is believed to have inspired Augustus Cotter in his manufacture of the first rifle 1925 antique floding desk .
The contemporary view was that the main function of the grooves of the rifled barrel was to add to the resistance offered by the bullet to the explosion of the powder; and that the spin imparted to the bullet enabled it to bore its way into the target queen ann gate leg table . Robins proved that these theories were quite wrong nursing chair paw . He then went on to show that since the extra resistance of the rifling was not a factor in increasing the power of the explosion, the barrel should be as near smooth-bore as was consistent with spinning the bullet ball and claw tripod table antique . From this he deduced that instead of forcing the bullet in, it was better to have a bullet rather narrower than the bore, and to lay it on a patch of material greased on both sides, which would enclose the bullet and grip the rifling as the two were pushed up the barrel imperial gillow dining table . This method was already used in parts of Germany and Switzerland types of decoration on the shaft of a tea table .
Robins concluded with the following passage: ‘I shall close this paper with predicting that whatever State shall thoroughly comprehend the nature and advantages of rifled barrel pieces, and, having facilitated their construction, shall introduce into their armies their general use, with a dexterity in the management of them, they will by this means acquire a superiority, which will almost equal anything that has been done at any time by the particular excellence of any one kind of arms; and Will perhaps fall but little short of the wonderful effects, which the histories relate to have been formerly produced by the first invention of firearms 16 century antique english tables .’
In Germany rifles had been used as sporting weapons for very many years chippendale dining double pedestal . In 1709 the first group of German immigrants arrived in America, bringing with them a number of these sporting rifles “oliver bernard” pel . Also included in the party were some gunsmiths together with their tools gateleg table antiquequeen ann . The Germans settled down in the Lancaster Valley district of Pennsylvania, and proceeded, amongst other activities, to make rifles marquetry semi-circle drop leaf . The development of their rifles is of interest, for it was responsible for the first introduction of the rifle into the British Army art dec countries .
The German rifle of 1709 was a clumsy weapon pillars on casters . Its calibre varied from ‘75 to ‘875-, and it had a short barrel of from thirty to thirty-six inches antique silver candlesticks . The barrel was too short for the poor powder of the period, which was never fully consumed and consequently fouled the barrel badly telescopic table furniture . The ball was of the tight-fitting variety, hammered in with mallet and yammer chenghua footrims . Performance varied from rifle to rifle and was often erratic, for the type and twist of the rifling depended on the fancy of the maker bugatti oriental style desk .
The rifle which the Lancaster Valley gunmakers evolved from the original ‘Jaeger’ had a bore of 48, a barrel of forty inches in length, uniform rifling and greatly improved balance noritake earlyware . Furthermore, the bullet was of slightly smaller diameter than the bore and smeared with grease or tallow, so that it slid easily down the barrel 16th century english joyned table . In the stock of the louis xvi revival sideboard . rifle was an aperture covered with a hinged flap in which the bullets were stourbridge pink marbled overlaid on opaline glass . kept antique french inlaid dresser .
On a still later version the bore was further reduced to ‘45- inch calibre and the barrel lengthened to forty-two inches cabinet makers marks england . With the longer barrel less powder was required, range and accuracy were improved, and there was considerably less fouling due to the better combustion serpinetine leg table antique oak . The next improvement was the use of the greased patch instead of greasing the bullet porcelain wincanton . This had the effect of filling the grooves of the rifling, so that 16th century english chamber pot .the compression behind the bullet was still greater, and the patch cleaned the rifling swedish bedside tables .
By 1740 the Lancaster Valley, or Pennsylvania, as it came to be known, rifle had become almost standardized inexpensive antiques . The barrel had now an even greater length of forty-four inches; and it was flared at the muzzle and had a slightly choked bore francaise antique . This was the weapon which was used with such effect against the British troops in the War of Independence hepplewhite sofa .
The American troops used their rifles for skirmishing and guerrilla attacks, whilst for close-order fighting the bulk of the infantry were armed, as were the British, with the smoothbore musket english apostle antique teaspoons . Nevertheless the elusive and accurate riflemen formed a valuable arm of the American forces, and they were particularly formidable in broken or wooded country parts of chambersticks .
The British Army had no riflemen of its own to provide a similar harassing and protective screen oriental gated tea tables . Several of the German states, however, included Jaeger regiments, armed with the rifle, in their forces aztec “art deco” rectangle vase . The British Government therefore made inquiries and succeeded in persuading the Landgrave of Hesse to hire a body of his troops antique furniture deutch . The solution, however, was not a happy one 17th century french fashion . The peasant conscripts in the Hessian regiments were largely untrained, and the rifle with which the Jaegers were armed was of very poor quality, and did not stand comparison with the Pennsylvania rifle early 19th century upholstery fabric . It had a short barrel, rifled with six or seven grooves, and an oversize•bullet which was driven in with mallet and ramrod antique console dresser . Its rate of fire was only about one shot a minute, as compared with the two or three shots of the Pennsylvania rifle 16 century chairs caved . It was, in point of fact, very similar to the old original rifles which the Lancaster Valley settlers had brought with them from Germany antique queen anne style burr walnut coffee table .
Captain Hanger, already mentioned as the author of To 111 Sportsmen, was himself an officer in one of the Jaeger regiments; and one of the best rifle shots in England art deco antique dresser . The appreciation of the American rifle which he gives in his book is therefore worth quoting staffordshire flatback fakes . He says:
`I never in my life saw better rifles (or men who shot better) than those made in America antique armchair ardwood anglo . They are chiefly made in Lancaster, and in two or three neighbouring towns in that vicinity, in Pennsylvania de coene art deco . The barrels weigh about six pounds two or three ounces, and carry a ball no larger than thirty=six to the pound; at least I never saw one of a larger caliber, and I have seen many hundreds and hundreds 19th century side tables .

`Coloncl, entry dressing table .now General Tarleton, and myself, were standing ,a few yards out of a wood, observing the situation of a part of the enemy which we intended to attack candelabra empire style reproduction .

In spite, however, of entering upon the American War without any riflemen or rifles at all, the British Army very shortly acquired the best and most revolutionary rifle in the world walnut gaming table with pillar legs . Its inventor was Captain Patrick Ferguson of the 71st Highlanders oak drop leaf gate leg side table . Ferguson commanded the Light Infantry company of his regiment antique brown staffordshire . One of the finest rifle shots in the Army, and convinced of its value as a military weapon, he had designed this rifle to prove his theories gustov klimt chairs . The whole of his company had been equipped with it, probably at Ferguson’s expense, and then trained as a rifle unit carpets oriental .
The great advantage of the Ferguson rifle was that it could be fired at a greater speed, not only than any other rifle, but also than any smooth-bore musket berkey & gay antique chest of drawers lion design . It was a breech-loader, and it was the ingenious loading mechanism which was responsible for its high rate of fire chicken coop shelves .
A plug, a little larger than the bore, was screwed into the barrel behind the chamber and passed from underneath the stock right through to the top, where it fitted flush with the barrel walnut ball claw gateleg table value . When this plug was closed it formed the breech-piece scandinavian wood furniture maker’s marks . It had twelve to fourteen rapid twist threads instead of a single screw thread jan van mekeren . The lower end was attached to a lever which formed the trigger guard english ironstone”, staffordshire . Swinging the trigger guard round laterally for three-quarters of a turn lowered the plug J inch and opened the aperture for loading: the top surface of the plug being now flush with the lower surface of the barrel leopold stickly table 1959 .

There was a leaf back-sight which was adjustable for ranges from ioc, yards to Soo yards moser antique glass . The bayonet had a flat, single-edged sword blade 25? inches long reproduction mochaware .
In 1776 Ferguson with his company, all volunteers, was ordered to America early 17 centurey gateleg tables . While the men were preparing to embark Ferguson gave a demonstration of the rifle’s capabilities antique walnut dropleaf tables . The demonstration was reported by the Innual Register of June 1776 as follows:
`On the 1st of June, 1776, he made some experiments at Woolwich, before Lord Viscount Townshendj Lord Amherst, General Harvey, D6ragliers, and several other officers with the rifle gun on a new construction, which astonished all beholders http://antcollectors.com/antique-furniture/art-deco-cabinets-and-sideboards-british-walnut-sideboard-burled-maple-console-french-commode-french-side-cabinet-british-sideboard-british-display-cabinet-british-side-cabinet . The like had never been done with any other small arms open and closed dressing table, satinwood, english c, 1800 . Notwithstanding a heavy rain and the high wind-, he fired during the space of five minutes at the rate of four shots a minute, at a target two hundred yards distance chippendale cutlery . He next fired six shots in one minute, and also fired (while advancing at the rate of four miles an hour) four times in a minute furniture ecole de nancy . He then poured a bottle of water into the pan and barrel of the piece when loaded so as to wet every grain of powder, and in less than half-a-minute he fired with it as well as ever, without extracting the ball tall sheffield corinthian column . Lastly, he hit the bull’s-eye lying on his back on the ground, incredible as it may seem to many, considering the variations of the wind and the wetness of the weather vernacular scottish . He only missed the target three times during the whole course of the experiments british sideboards .’
Ferguson’s company sailed for America as an independent corps of riflemen anc clad in rifle green antique drop leaf table wooden hinges . Ferguson himself carried instructions authorizing him to select men from various regiments for training and incorporation in his command pier table empire . The Commander-in-Chief, Sir William Howe, did not, however, take kindly to this new force, and it does not appear that Ferguson was allowed to have much success in obtaining recruits silver apostles spoons .
The corps went into action for the first time at Elk Head on the 25th August 1777 gateleg drop leaf mahogany table . It then covered the advance of Knyphausen’s division to Brandywine antique table wooden hinge drop leaf . During this advance Ferguson, -with three of his men, was apparently carrying out a reconnaissance beyond the British encampment at Kennett Square, when the chance of changing history came within range of the Ferguson rifle paris antique pine dining furniture . The small party heard the sound of horses’ hooves approaching, and dived into cover at the edge of a wide clearing brass skimmer antique . Soon afterwards there rode into the clearing two mounted officers rare tureens . One of them was dressed in a uniform of blue and buff with, on his head, a large headdress described by Ferguson in his notes as a ‘remarkable cocked hat’ “desk”+”antique” . The antique 1920 art deco period pieces walnut china cabinet and buffet .other officer was a Frenchman in Hussar uniform art deco furniture cylinder . To fire, as Ferguson said afterwards, would have been like shooting a sitting grouse; and he and his men remained quietly watching until the pair finally rode off dressing table with porcelain figures .

This made it much easier to remain concealed, and on at least one occasion it resulted in an attack by a far larger American force being defeated william kent staffordshire .
Artillery Guns of the WWII
Running parallel with this unfolding story of piercing projectiles was the development of the hollow-charge principle into a viable weapon. This illustrates the adaptation of a well-documented scientific phenomenon to a weapon of war: almost 200 years ago a Norwegian engineer had observed that hollowing out the face of an explosive charge made it cut deeper into rock when blasting. In the 1880s an American experimenter, Monroe, found that when firing guncotton slabs against armour plate, the initials ‘USN’ engraved in the guncotton reproduced themselves in mirror-like form in the face of the armour plate. From his observations and reports the phenomenon became known as the ‘Monroe Effect’ and was a scientific curiosity for many years. Just before the First World War one or two inventors toyed with the idea of employing this effect in mines and torpedoes, but since no one really understood why it did what it did, it was difficult to engineer the idea into a practical form.
Just before the Second World War broke out, a Swiss consortium approached the British government to offer a ‘new and powerful explosive’ for anti-tank use—at a high price. The inventors refused to divulge any information until cash was forthcoming, but were prepared to demonstrate their projectile being fired. An astute observer from the Research Department of Woolwich Arsenal went to Switzerland to watch the firing; being a well-read expert on ammunition development and history, he realised that what he was watching was not a new and powerful explosive so much as a practical application of the Monroe Effect. Upon his return to Woolwich he duly reported this, and, since it appeared that the Monroe Effect could be made to work, research immediately began into applying it to a light anti-tank grenade which the infantry soldier could fire from his rifle. Before the outbreak of war, this ‘68 Grenade’ had been perfected and was in production, and carries the distinction of being the first weapon ever to reach the hands of troops which relied on the Monroe Effect, or as it came to be known, the Hollow-Charge Principle.
What is this Hollow-Charge Principle? Put simply, it consists of forming the forward surface of the shell’s explosive charge into a cone or hemisphere and then lining this with a thin metal liner. The shell is then fitted with a suitably shaped nose, for ballistic effect and also to give the vital ’stand-off’ distance. This is the distance from the target—a matter of a few inches—at which the explosive must be detonated in order for the hollow charge to work effectively. On detonating the explosive at its rear end, the detonation wave exerts an immense pressure on the metal of the liner; the cone shape virtually’focusses’the explosive energy and causes the metal of the liner to be shaped into a jet of finely-divided metal and explosive gas, shooting toward the target at speeds of up to 20,000 feet per second. The stand-off distance is necessary in order to allow this jet to form and accelerate. When the jet strikes the target plate, the pressure exerted is so great as to blast a hole through the armour, blowing splinters of metal from the inside and permitting the white-hot jet to pass into the tank where it will set fire to fuel or ammunition, and, of course, kill or injure the crew.
The great virtue of the hollow-charge shell is that its performance is always the same, irrespective of the velocity at which it strikes. Even if the shell were standing still when detonated, the penetration would be the same. Because of this, it could be fired from guns too small to fire the large cartridges needed to give the necessary velocity to normal piercing projectiles. As soon as the 68 Grenade was seen to be successful, design began on other hollow-charge projectiles. A great deal of work went into producing one for the 25-pounder, though in the end it was never issued, since the AP shot issued for that gun was quite satisfactory and there was no real need for a hollow-charge shell. Then came a request from India to produce an anti-tank projectile for the 3.7-inch Pack Howitzer, the modern version of Kipling’s immortal ’screw-gun’. This gun, a small and portable weapon, could not be made to fire a piercing projectile at anything like the velocity needed to defeat even Japanese tanks, and a hollow-charge shell was designed and placed in production. The same shell was used in the 95-mm howitzer, an abortive infantry support gun which never saw service as a towed weapon, though it was employed as a self-propelled support weapon by the Royal Marines in Normandy and by the Armoured Corps.
By 1944, though, sufficient basic research had been done into this principle for it to be seen that a spinning shell was not the ideal method of employing hollow charges, since the spin tended to spread the jet out and give poor penetration. Finned projectiles were more effective, and consequently no more artillery shells were designed around the hollow charge; it was extensively employed, instead, for infantry weapons such as the PIAT, the Bazooka, and a variety of rifle grenades.
The Germans, and later the Russians, embraced the hollow-charge shell wholeheartedly. The Germans began issuing shell in late 1940 and eventually almost every German field and tank weapon had a hollow-charge shell, thus giving every gun or howitzer an anti-tank capability. Indeed, so short were the Germans of anti-tank guns after the Russian invasion got under way, that they hastily collected up all the French army’s 75-mm guns and assembled hundreds of them on to redundant anti-tank gun carriages of German design. A hollow-charge shell was produced and these makeshift weapons were deployed in Russia to stem the advancing Soviet tanks until 75-mm and 88-mm anti-tank guns were in sufficient supply. Judging from appearances, the Soviet hollow-charge shells were developed as virtual copies of German designs which had been captured.
In addition to artillery shell Germany also used the principle for infantry weapons such as the Panzerfaust, rifle grenades, and even a small shell which could be fired from a signal pistol. They also employed the principle in an ingenious attempt to prolong the life of the prewar 37-mm anti-tank gun, whose piercing projectile was, by 1942, no longer effective against current tanks. A large hollow-charge bomb was fitted with a hollow tail carrying fins; within this tail was a stick which fitted snugly into the barrel of the 37-mm gun, allowing the tail and fins to slide over the barrel. A blank cartridge completed the outfit, and this was used to fire the stick bomb to ranges of 300 to 400 yards. The bomb’s warhead was about 6 inches in diameter and carried about 8 pounds of explosive, giving a devastating effect at the target. In all fairness, it must be pointed out that Lieutenant-Colonel Blacker, inventor of the PIAT and the `Black Bombard’ of Home Guard fame, had proposed a similar 60-pound stick bomb in 1940, to be fired from the 25-pounder, but the idea was turned down on the grounds that it might lead to misemployment of the gun as a purely anti-tank weapon. (This misemployment theme was not confined to the British side: many German Flak commanders bewailed the loss of their valuable 88-mm Flak guns as they were whittled away to provide anti-tank defences.)
The third subject is the application of new principles to gun design. The first of these to be unveiled was the taper-bore antitank gun, which has already been touched upon. This was the child of a German engineer called Gerlich, who, advocating his principle of attaining high velocity without attracting any buyers, had been stumping the world for several years. He was briefly employed by both the US War Department and the British War Office at various times, but his ideas on improving shoulder arms were felt to be impractical. He eventually settled in Germany and saw his idea accepted as an anti-tank weapon. The 28/21-mm came first, then a 42/30-mm and finally a 75/50-mm. Unfortunately, the lack of tungsten carbide for the special projectiles spelled the demise of these weapons, but experiments continued with coned bores and coned muzzle-adapters for guns of various calibres up to as large as 280-mm, in order to boost velocity and range. These were intended to use high-explosive shells, which were more practical in the larger calibres, though the development of a shell which would stand up to being squeezed down the gun barrel was no easy task.
The second, and more widespread, new line of thought was the recoilless gun. Like most weapon ideas, there was nothing really new about it: Commander Davis of the US Navy had produced a recoilless (RCL for short) gun during the First World War which was adopted by Britain as an anti-Zeppelin aircraft weapon. The virtue of an RCL gun is that by having no recoil one needs no complicated hydraulic buffer system to absorb the firing shock: one need only make the gun-carriage strong enough to take the weight of the gun, instead of being strong enough to withstand being fired from—an ideal state of affairs for an aircraft weapon, particularly in the stick-and-string era. Davis’s idea is worth looking at, although outside our time scale, since it is the classic recoilless weapon. He simply provided the gun with two barrels, one pointing forward which fired a normal shell, and one pointing rearward which fired an identical weight of grease and buckshot. When the central cartridge was fired the shell and countershot departed at equal speed in opposite directions and cancelled each other’s recoil. From this it can be seen that if you make the countershot (say) one-fifth of the weight of the shell and fire it out at five times the speed, then the gun will still be in balance. Taking this idea to its logical conclusion one finishes up firing out of the back of the gun a fast, light stream of gas, still balancing the recoil since the weight times speed of the gas is the same as the (greater) weight times (slower) speed of the shell.
Cutting down the recoil
This was the principle which the Germans revealed in Crete when their troops appeared armed with a 75-mm RCL gun. The shell was the standard 75-mm shell, but the cartridge case had a frangible plastic base which held for long enough to allow pressure to build up and start the shell moving, then blew out through a hole in the breech-block, releasing the balancing stream of gas. The all-up weight of the gun, on its ex-machine gun tripod, was only 320 pounds, whereas the weight of the standard 75-mm field gun was about 11/2 tons—no mean saving for airborne carriage. A 105-mm version soon followed, weighing 855 pounds as opposed to the 105-mm 1E FH18’s 4,312 pounds, and many more developments began in this field to provide light weapons for mountain troops and infantry, particularly for anti-tank use. (It ought perhaps to be pointed out that the Panzerfaust was in fact a recoilless gun, and not, as generally supposed, a rocket launcher). Eventually RCL guns of up to 380-mm calibre were under development, including many for slinging beneath aircraft to carry artillery aloft for the battle against the Allied bombers, but none of these came to fruition.
n Britain, the RCL gun development during the war is a scarcely-known story of one man’s persistence. Sir Denis Burney, airship designer and prolific inventor-engineer, began to be interested in the recoilless principle early in the war. In order to prove his theories he converted a four-bore gun into a recoilless weapon and proceeded to fire it from the shoulder with ease; it must have been the world’s most comfortable duck gun. Having proved his point he proceeded to design a series of RCL guns ranging from 20-mm to 8-inch calibre. In addition to designing the guns, he expanded his theories and designed special ammunition to take advantage of the ballistic peculiarities of the weapon. He argued that since the rearward blast was taking place, the pressure within the gun would be less than with a conventional type, and the shell would be subjected to a more steady thrust. In which case it would be possible to make shells with thinner walls, which would carry greater charges of explosive than previously possible. He then went further, and reasoned that, since the shell walls were thin, if the shell were to be filled with the then new plastic explosive, it would spread on to the surface of the target like butter; a fuse fitted in the base of the shell would then detonate this plaster and blast in the target. His envisaged target was either the concrete emplacements of the European coast, or the palm-reinforced Japanese bunker, and he called his shell the Mal I buster’.
In 1944 his designs were accepted and a 3.45-inch (the same calibre as the 25-pounder) shoulder-fired gun, a 3.7-inch towed gun, a 95-mm towed howitzer, and a 7.2-inch towed howitzer were prepared for production. The 95-mm was also jeep-mounted—the first application of what has since become a standard method of carrying these guns. The 7.2-inch soon fell by the wayside, since it had been intended solely as a means of defeating the Atlantic Wall emplacements, but other weapons were found to do all that was needed. The 3.45-inch was intended as an infantry weapon in the jungle, enabling one man to carry what was virtually a 25-pounder punch on his shoulder. The 3.7-inch was proposed as the future infantry anti-tank weapon, and the 95-mm was contemplated as the airborne field gun to replace the US 75-mm howitzer and the 25-pounder. However, before the guns were produced in sufficient quantity for issue, the war came to an end; some 3.45-inch and 3.7-inch guns were issued to selected infantry units to obtain their reaction to RCL guns as a general thing, and the 95-mm was abandoned altogether.
The principal difference between the Burney guns and the German type was that the Burneys had much longer barrels, and used cartridge cases which, instead of the plastic blow-out base, used many perforations in the sidewall to release the gas into a surrounding chamber, from whence it was passed back to a number of vents around the breech.
Concurrently with Burney’s work in Britain, American designers began on similar weapons. A 105-mm howitzer T-9 was developed on similar lines to the German 105-mm, having a blow-out base to the cartridge. Another team developed 57-mm and 75-mm weapons which used perforated cases similar to the Burney pattern but having more and smaller holes, and also had the shell driving band pre-engraved in order to reduce the pressure inside the gun. Both these latter weapons were accepted for service early in 1945, saw service with the US Army in the Pacific theatre, and remained in service for many years. A third team, this time under the auspices of the National Research and Development Council, developed a 4.2-inch RCL mortar, an unlikely-sounding weapon which so as to be able to fire direct at the target at low angles, carried a small rocket on the nose of the shell to push it down the barrel’and fire the propelling cartridge in the usual mortar fashion. Due to the blast of the rearward jet, it could only be fired at low elevations; there was a certain amount of enthusiasm for this weapon but it never entered service.
Perhaps the best summing up of all wartime development on RCL weapons was made in a wartime report: ‘Undoubtedly a number of effective recoilless weapons have been developed, but they are being accepted with reserve, and will only be considered as supplementary to older and more orthodox weapons which have proved their accuracy and reliability in service.’
There is, unfortunately, no space here to delve into more recondite stories of research and development: the British 13.5-inch gun linered-down to 8-inch calibre which, fired from Dover, reached a range of over 100,000 yards; the British and American development of flying artillery, which culminated in the mounting of a 32-pounder anti-tank gun in a Mosquito; the German V-3 multiple-chamber gun which was intended to shell London; the American 36-inch mortar ‘Little David’, designed to batter Japanese strong-points; the German rocket-assisted and ramjet-assisted heavy artillery shells which promised vast increases in range; or the Anglo-American development of the electronic proximity fuse which proved the answer to both ‘Doodlebugs’ and kamikaze pilots. These and similar stories may only interest the specialist, but they, together with what has been written here, serve to illustrate the incredible range of inventions brought into play in the war waged between the designers and inventors of each side, each endeavouring to get one step ahead of the other, if only temporarily.
