Hennem was requested to make thirty of his screwless locks for Durs Egg’s breech-loading cavalry carbines austro hungarian empire architecture .: and two months later he was directed to make ninety muskets to the design of the Master-General, of the Ordnance (now the Duke of Richmond) and to fit them with his locks chippendale drum table 2 drawers . On the ist October 1785 Major-General O’Hara, Colonel of the 22nd Foot (now The Cheshire *Regiment), invited Hennem to fit his locks to all the muskets in his regiment john widdicomb furniture/french provincial . O’Hara must presumably have seen and been extremely impressed with the 2oth’s trial muskets, for the alteration was a very expensive one to carry out under regimental arrangements amphora czechoslovakia . It must have looked to Hennem as if the future of his lock was assured, and yet it seems that O’Hara’s was the last important order that he had meubles decoration antique europe .
On the 22nd February 1′786 Hennem offered *to modify the stocks of Sergeant’s, carbines and to replace the existing locks with his own for an inclusive charge of 155 barley sugar twist pillars timber . -for each carbine george iii serving table . This offer was politely rejected with the explanation that a change of the firearms of the Army was under consideration small antique sutherland table . The change was due to a competitive venture by Hennem’s erstwhile backer or co-operator, Henry Nock delftware t.i holland .
Nock was one of the leading gunsmiths in both London and Birmingham ivan chermayeff, furniture . He held Government contracts for the manufacture of muskets and carbines, and produced, in addition, many ingenious and original weapons of various types brass frame girandole images . He designed, for instance, a ‘volley gun’ with seven barrels all fired by one hammer at the same time, and intended for Naval boarding parties; four- and seven-barrel revolving pistols; a heavy piece, or ‘wall-gun’, with a repeating action; and several others how much is a victorian dressing table worth . He was obviously the type of gunmaker to whom Jonathan Hennem’s lock would have appealed silver spoon design europe 18th century .

It may be that Hennem was too independent a character for Nock’s liking pier roger vandercruse . In any case he had found an eccentric genius who had invented a lock which was somewhat similar to Hennem’s, though more complicated bulbous leg dining table . This was a mathematician named George Bolton, who at one time had been tutor to the children of George III 18th century silver mote spoon . He had devoted a large part of his spare time to the improvement of gun-locks; and seems to have established a gun shop in London in 1773 with another Bolton (F luxury art deco upholstery fabrics . H jennens & bettridge tole tray .), who was perhaps a brother rococo revival marquetry-inlaid wardrobe .
The Bolton lock also had no screws, and all its components were enclosed between two plates, of which the outer (in the position of the normal lock plate) was fitted with pins to hold the moving parts antique double claw pedestal dining room table . A special feature was the accurate machining to standard dimensions, which permitted the easy replacement of breakages antique inlaid pembroke table .
Nock seems to have acquired the sole rights in this lock, for most, if not all, of those made for the Government bear his name ‘H scheid enamel . Nock’ on the plate tripod table, claw and ball foot, antique . In, probably, 1785 Nock produced a new range of military firearms, comprising musket, pistol and carbine, which he submitted as suggested replacements for the Brown Bess series of flintlocks antiques furniture,josef hoffmann . Initially he seems to have* met with considerable success chinese porcelain wall decoration mask history . Trials carried out with his arms must have been satisfactory, for they led to a cessation of orders to Hennem, and a large number were issued to regiments of Horse and Foot for extensive trial turn top walnut tea/card table . Further, it does not appear that art deco consoles . ultimate approval was doubted, for a very large number of the locks were manufactured, and it is reasonable to suppose that these were intended for the conversion of existing flintlocks antique collectors cabinets . Nevertheless the Nock arms were rejected after only a short trial 1940’s art deco black and gray lacquer bedroom set prices . There must have been some weakness in the lock which led to it comparing unfavourably with the sturdy old Brown Bess under active service conditions apostle tea spoons made in england .
One of Nock’s most notable contributions to the development of firearms was the invention of his ‘Patent Breeching’ renaisance design dining table made .
It was too expensive a refinement ever to have been adopted for military firearms, but it drew attention to the advantages obtained by more rapid and more efficient explosion of the charge german 1930 furniture value .
It had been known for some time that if, instead of the ordinary flat-surfaced breech-plug, a special type known as a `chamber-plug’ was fitted, a more powerful explosion resulted antique double pedestal dining room table . In this form of breech the diameter of the powder chamber was slightly less than the bore of the gun, and the breech end was a rounded hollow cut out of the breech-plug 5″ antique rectangular drop leaf table with drawer . From the centre of this hollow was drilled a narrow channel, called the `ante-chamber’, which received a portion of the powder and which connected at right angles with a vent running outwards to the touch-hole of the gun antique brass mirror convex eagle . The idea was that the flame
from the touch-hole, instead of igniting a corner of the charge, “antique furniture” - writing bureau and display cabinet .9
passed through the ante-chamber and through the centre of the powder, thereby igniting all of it at the same moment 17th century antique trinket boxes . The greater power of the explosion resulted in a higher initial beilby glass prince of wales feathers newcastle . velocity of the bullet; in other words, the full force of the powder was exercised in a shorter distance types of bureaux . It was therefore possible to use a shorter barrel; and the barrels of ‘chambered’ pieces were from six to ten inches shorter than those of firearms with the normal pattern of breech characteristics of english medieval gateleg table .
The disadvantage of the ‘chambered’ gun was that the flame had to travel down the touch-hole vent and thence through the ante-chamber before it reached the main chamber; a considerably longer distance than the usual direct contact between touch-hole and charge cabriole leg demilune table . The flintlock already suffered from the delay between pressure on the trigger and ignition of the charge antique oval drop leaf dining table with turned legs . In ‘chambered’ guns it was much greater, and the sportman had little chance of hitting a fleeting target art-deco-1920-1930-wood .
Nock’s feat was to invent a breech which produced the same power as one fitted with the chamber-plug, and yet with less delay between the fall of the cock and the explosion than was experienced with the ordinary flintlock breech antique rectangle drop leaf table cabinet .
Instead of a hollow the Nock breech-plug had a deep cavity cut in it to receive the charge antique french cabriolet dresser . The rounded end of this cavity was connected by a very short passage to a wide ante-chamber cut through the breech-plug from one side to the other art decos exotic bronze chair . One end of this ante-chamber was closed by a screw, to give access for cleaning, and the other by a gold or platinum plug drilled in the centre with the touch-hole 18th century drum tables . Since in loading some powder fell through into the ante-chamber, and the passage separating it from the main chamber was only about -at inch, the touch-hole was as in close effective contact with the charge as in the conventional breech antique walnut dining table 10 foot . Furthermore, the powder in the ante-chamber was so closely confined that it exploded as soon as the flame from the priming powder reached it, instead of being set on fire first as in the normal piece turn a silver tray into a table .
The vast improvement in the performance of flintlock weapons which was effected by Nock’s invention has been rather overshadowed by Forsyth’s more efficient solution of the same problem with the percussion lock english antique trays .
SWORDS IN THE
EIGHTEENTH CENTURY
Progress towards the standardization of swords throughout the Army was far slower than in the case of firearms jean rene prou furniture . Regulation patterns for musket, carbine and pistol had been introduced in the reign of King James II; but it was not till near the end of the eighteenth century that there was Army uniformity of swords 19th c english tin glazed pottery . Long before that there must have been similarity in the swords carried by regiments of the same arm of the Service because there was bound to be a limit to the number of types which the swordsmiths turned out, and these types would conform in general to popular military demand clock singer music candlesticks . Variations between regiments, therefore, would be chiefly minor modifications of the normal type in accordance with the taste of* the Colonels sofa carved top rail . The officers’ swords would tend to differ much more than those of the men, because being more expensive and privately purchased there would be little difficulty in satisfying even the most exotic requirements chinese porcelain decorators . But two factors would tend to preserve some uniformity: firstly, the Colonel of a regiment would often, probably, insist on his officers being armed alike; and secondly, the fashion of the moment is a very powerful factor, particularly amongst very young men value of primitive antique work bench .
After the end of Queen Anne’s wars on the Continent infantry soldiers still seem to have been armed with the hanger 19th century empire daybed . It appears, however, to have been exceedingly unpopular; probably because the possession of a bayonet would make a sword seem an unnecessary encumbrance meissen cris de paris . Several infantry units seem to have stopped wearing swords altogether, for on the 1st December 1724 an order was issued to the Army which by its wording inferred a widespread irregularity biedermeier candelabra . The order read:
`The King is determined to have all the N what is a double gate leg table .C macassar ebony furniture .O ironstone ware japanese willow .’s and men of His foot forces wear swords antique round dining tables with extensions .’
Nevertheless Authority was fighting a losing battle gothic arch furniture . Once the fighting troops have decided that a particular piece of equipment serves no useful purpose there is little chance of its being carried on active service weimar germany china antique . By the middle of the century many regiments had far less than their proper complement of swords, and some had none at all makers of antique table clock with music in china .
At some period Grenadier companies were given basket-hilted swords, instead of the usual brass-hilted hangers wardrobes 19th century . The Grenadiers of the 4th Foot (later The King’s Own Royal Regiment) had them in 1727, those of the 40th Foot were wearing them in about 1750, and a water-colour by Sandby shows the Grenadiers of the Coldstream wearing straight steel basket-hilted swords in 1747•
There does not seem to have been any material change during the- first half of the eighteenth century in the type of swords carried by infantry officers refectory table . In 1746 those of the 4th Foot had a steel hilt, and the scabbard was leather with steel mounts antique deco tub chair .
A typical cavalry sword of 1750, carried by both Horse and Dragoons, had a straight single-edged blade and a full basket-hilt 20th century furniture development in france . The pattern of basket-hilt varied from regiment to regiment, and those of the King’s Own Regiment of Dragoons, for instance, were of brass french animal chairs . The 3rd and 4th Irish Horse, instead of a straight blade, had one which was curved and slightly shorter than the normal kommode roentgen . The length of the blade was 31-1 inches and the breadth 1j inches gilt metal mounted pier table .
There is a Dragoon sword of about 1742 which is of interest as probably being of a fairly typical general pattern, and yet with distinctive regimental characteristics octagon mahogany antique table value . The blade is straight with a single edge and a length of thirty-six inches john walton antiques . The hilt is iron, but only half basket, and with a fishskincovered hilt bound with twisted brass wire how much would an antique clawfoot dresser cost . From the hilt hangs a buff leather sword knot with runner and tassel value of silver candelabra . The scabbard is of black leather, carried in a frog suspended from a shoulder belt 1980 scandinavian leather chair recliner barcelona .
In 1735 the drummers of the 8th Dragoons were distinguished by carrying scimitar swords; and in 1754 special swords were used to denote rank in the Royal Dragoons: brass-hilted swords being issued to serjeants and corporals 16th cent. sideboard .
When in 1755 a Light Troop was added to each regiment of Dragoon Guards and Dragoons on the British establishment, the Royal Warrant laid down that the men were to have `a short cutting sword 34 ins picture of pennsylvania house antique cherry buffet claw feet . long in the blade with a light hilt without basket’ penwork italian . This regulation was typical of the time in that it gave a very general specification and ample scope to Colonels of regiments to choose what they wished antique mahogony carved dressing table . The blade could apparently be either straight or curved and the hilt of any pattern so long as it was light and without a basket antique draw leaf tables . Captain Hinde, in his The Discipline of the Light Horse, deals with both the Light Troops and the subsequent regiments of Light Dragoons, the first of which was raised in 1759 confidante sofas . It is unlikely that there was very much change in the Light Dragoon sword between the time the Light Troops were raised and the formation of the Light Dragoon regiments; but at the time Hinde wrote the sword blade had been lengthened to thirty-seven inches old silver lustre myott . Hinde’s description of the swords carried by officers and men is given in Chapter V, and it will be- noted that the pattern of sword was still left to the choice of the commanding marquetry inlaid trays . officer seated harlequin with a tankard, johann kandler . An illustration in Hinde’s book shows a trooper of a regiment of Light Dragoons armed with a straight-bladed double-edged sword, with no hilt protection other than counter curved quillons indian antique tea kettles . In addition to the mounted pattern, officers apparently had a special sword for parades on foot verlys france . Of these Hinde says: ‘The Officers Parade Swords for Foot Duty, are about 28 Inches Long in the Blade, and worn in a Belt round the Waist’ antique side chair desk . Even the length of swords, however, does not always seem to have complied with regulations french 18th century bureau cabinet . Of his own regiment, the Royal Foresters, Hinde says: `Their Swords were remarkably Long, and quite straight’ makers of 1940’s american art deco furniture .
Farriers did not carry swords antique fold over table . According to Hinde: ‘They carry an Ax at their Left Side in a Belt of the same Colour of the Mens over the Right Shoulder, and a White Apron rolled back on their Left Side jupe patent extending dining table . When the Men draw their Swords, the Farriers take their Axes from, their Sides, and place the Handle on their Right Thighs Advanced, with the Edge turned towards their Horses Heads; they might carry a Saw on their Right Sides, in a Belt over the Left Shoulder, and a Spade in a flat Bucket under the Right deco tub chair . Budget, like the Carbines coming under the Right Arm art deco antiques contemporary world paris .’
Captain Hinde’s remarks on weapons may be fittingly concluded with his method of preventing arms from rusting antique american empire card table with scroll feet . This is as follows:
` antique furniture empire chest of drawers .d Receipt to keep Zrms from Rust nouveau art draws .
‘One Ounce of Campshire to Two Pounds of Hogs-Lard, Dissolve them together and take off the Scum; Mix as much Black-Lead as will bring them to an Iron Colour: Rub your Arms over with this, and let it lie on Twenty-four Hours, then Clean them as well as possible with a Linen Cloth, and they will keep without the least Rust for Six Months fold over tea table .’
The Royal Warrant of 1768, which dealt in detail with the clothing and equipment of the Army, made some attempt to secure reasonable uniformity in swords value staffordshire engine turned redware teapots 18th century . It laid down that the swords of each regiment were to be uniform and proscribed patterns and colours for sword-knots, belts, etc 19th century antique hall table ., and gold or silver coloured metal for hilt and scabbard appointments, according to the colour of the buttons old fashioned table brass metal claw feet on casters .
As regards the rank and file of the infantry the Warrant recognized what was practically a fait accompli empire card table . It said:
‘SWORDS antique card table withe one flap .
`All the Serjeants of the Regiment, and the whole Grenadier Company, to have swords spanish table antique turned legs . The Corporals and Private Men of the Battalion Companies (excepting the Regiment of Royal Highlanders) to have no Swords 16th century english joyned table .’
The Royal Highlanders (42nd Foot, or Black Watch) were presumably excepted because, like the Grenadiers, they wore the broadsword with basket hilt chippendale pinecone . The privilege was not appreciated, however, and the 42nd got into hot water for discarding their swords on the pretext that bayonets had proved far more useful in the American War 18th century antique gate leg table . However, the 42nd’s opinion of infantry swords seems to have received support from senior officers with war experience, for in 1783 they were given permission to return their swords to store french cabriole leg tracing pattern . The following year a Board of General Officers, which had been established to examine the soldier’s equipment in the light of the war in America, reported that Grenadiers had never worn their swords in action and recommended their abolition 19 century mahogany gateleg table . As a result swords were abolished throughout the infantry for all rank and file except drummers antique pottey work table . For these latter, the Royal Warrant of 1768 had specified ‘a short sword with a scimitar blade’; which was, in point of fact, a hanger vintage cherry table with queen ann legs .
Somewhat paradoxically the sword was about to become the principal weapon of the infantry officer at about the same time as it was being withdrawn from the remaining rank and file maurice dufrene, design .
The changes in officers’ shaft weapons is somewhat complicated 18th century occasional table . At the beginning of the eighteenth century captains and lieutenants of infantry had pikes and ensigns find 1954 crystal green tinted wine glasses . half-pikes telescopic table pedestal . In 1710, or thereabouts, captains reverted to the spontoon yuan muhammadan blue . At possibly the same time the lieutenant’s weapon was changed to a half-pike antique hanging corner display cabinet . In 1743 all officers of foot were directed to carry spontoons s s meissen mark . The spontoon was then the infantry officer’s principal weapon; but not, it seems, a very popular one gabriel viardot . That some difficulty was experienced in making officers carry it is shown by the following extract from an order book of the Brigade of Guards stationed in Germany in 1761-2:
`28th April rectangular table dressing . Colonel Thomas having remarked that the use of the espontoon is grown into a kind of disuse amongst the Officers of late, the naked sword or firelock being substituted in its room (a liberty which never used or ought to be allowed but upon emergencies), desires it may be resumed on all occasions in the Coldstream Battalion when it used to be!
The carrying of a ‘firelock’ was an adoption of the practice in Grenadier companies where all officers carried a light flintlock, generally a privately purchased weapon staffordshire figure prince “zebra” .
The American war finally dealt the death blow to the officer’s spontoon antique vargueno . Of the 63rd Foot in 1784, for instance, the Inspecting General commented: ‘Just arrived from America, where the officers never made use of espontoons; saluted with swords’ antique buffet sideboard signed by cabinet maker .

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.
