BARRAGE

In warfare, a barrage is a linear concentration of artillery fire used to interpose a screen of bursting shells between attacking and defending troops. When fired by a defending force to prevent an attack reaching its lines, a
barrage may be a simple line of fire in front of a position or shaped so as to surround the position - a 'box' barrage. Fired to assist an attack, a
barrage may be stationary, to prevent reinforcements reaching the threatened area, or moving, to act as a continuous screen ahead of the advancing force. Normally using high explosive shells, in the Great War barrages often included gas and shrapnel projectiles so as to present a more complex threat to the target.

BASTION

Picture of Bastion

A bastion is a work projecting outward from the main enclosure of a fortification, consisting of two faces and two flanks, and so constructed that it is able to defend the adjacent curtain, or wall which extends from one bastion to another, with a flanking fire. Two adjacent bastions are connected by the curtain, which joins the flank of one with the adjacent flank of the other. The distance between the flanks of a bastion is called the gorge. A lunette is a detached bastion. There have been various forms of bastion through the ages:

A composed bastion is one in which the sides of the interior polygon are very irregular, with the effect of making the gorges also irregular.

A cut bastion is one which has a re-entering angle instead of a point.

A deformed bastion is one in which the irregularity of the lines and angles prevents the structure from having a regular form.

A demi-bastion is a bastion composed of one face only with a single flank and a demi-gorge.

A double bastion is a bastion raised on the plane of another.

A flat bastion is a bastion erected in the middle of a curtain when the latter is too long to be protected by the bastions at its ends.

A hollow bastion is a bastion hollow in the interior, that is between the flanks and the faces of the point.

A regular bastion is one so planned as to possess a true proportion of its faces, flanks and gorges.

A solid bastion is one solid throughout its entire structure.

BATTERING-RAM

Picture of Battering-Ram

A battering-ram was an engine used in war in ancient times to beat down the walls of besieged places. The ancients employed two different engines of this kind - one suspended in a frame, the other movable on wheels or rollers. They consisted of a beam or spar with a massive metal head, and were set in motion either by a direct application of manual force or by means of cords passing over pulleys and then impelled by men against the wall or gates.

BATTLE

A battle is a combat between two armies. In ancient times and the middle ages the battle-ground was often chosen by agreement, and the battle was a mere trial of strength, a duel en gros; and as the armies of the ancients were imperfectly organized, and the combatants fought very little at a distance, after the battle had begun manoeuvres were much more difficult, and troops almost entirely beyond the control of the general. Under these circumstances the battle depended almost wholly upon the previous arrangements and the valour of the troops.

In the 19th century, however, the finest combinations, the most ingenious manoeuvres, were rendered possible by the better organization of the armies, and it was the skill of the general rather than the courage of the soldier that determined the event of a battle. By the Great War of 1914 tactics had changed with the advent of rapid firing weapons, long range artillery and armoured warfare.

Traditionally battles were distinguished as offensive or defensive on either side, but there was a natural and ready transition from one method to the other. As a rule the purely defensive attitude was condemned by tacticians except in cases where the only object desirable was to maintain a position of vital consequence, the weight of precedent being in favour of the dash and momentum of an attacking force even where opposed to superior forces. Where the greatest generals have acted upon the defensive, it has almost always been with the desire to develop an opportunity to pass to the offensive, and having discovered their opponent's hand, to marshal against the enemy, exhausted with attack, the whole strength of their resources. Napoleon won more than one great victory by this method, and Wellington's reputation was largely based upon his skill in defensive-offensive operations. Tacticians have divided a battle into three periods: those of disposition, combat, and the decisive moment. In some measure they require distinct qualities in a commander, the intellect which can plot a disposition being by no means always of the prompt judgment passing to instant action which avails itself of the crucial moment to crush an enemy.

BATTYE GRENADE

The Battye grenade was a simple hand grenade developed during the Great War and issued to British troops in 1915. It consisted of a cast-iron cylinder with an open end, filled with about 2.5 ounces of ammonal or a similar explosive and closed with a wooden plug. A hole bored through the plug allowed the insertion of a length of time fuse and a detonator. At the outer end of the time fuse was a percussion cap which, when struck, ignited the fuse to give a delay of about four seconds before the grenade exploded. A safety pin passed through the fitting prevented the cap from being driven down by accident.

BAYONET

A bayonet is a short sword attached to the muzzle of a firearm. The bayonet was placed inside the barrel of the muzzle loading muskets of the late 17th century. The sock or ring bayonet, invented 1700, allowed a weapon to be fired without interruption, leading to the demise of the pike. Since the 1700s, bayonets have evolved into a variety of types. During the Great War, the French used a long needle bayonet, the British a sword bayonet, while the Germans adopted a 'pioneer' bayonet with the rear edge formed into a saw. As armies have become more mechanised, bayonets have tended to decrease in length. Although many military leaders have advocated the use of the bayonet, in practice it has been rarely used.

BLACK WATCH

The Black Watch (Watch or Highland Watch) was a British army force raised in 1729 to keep peace in the Highlands during the times of the Jacobite intrigue. The regiment was raised from companies employed to watch the Islands of Scotland and subsequently became renamed the Royal Highlanders and had the nickname of the Black Watch from the black tartan they wear. The Regiment's first blooding occurred in Flanders in 1745, in the War of Jenkin's Ear at the Battle of Fontenoy, where the French dubbed them 'Highland Furies'. In 1751 the Regiment was numbered the 42nd, The Gallant Forty Two. Seven years later the title 'Royal' was granted and it became the 42nd Royal Highland Regiment.

The Black Watch saw action in the Americas, most notably in Ticonderoga and the Heights of Abraham, and acquired its present badge and motto 'Nemo me impune lacessit' which refers to the Thistle and means 'nobody provokes me without being hurt'. In 1759 the red hackle, seen in the feather bonnets and worn by all ranks of the Black Watch, was first presented at Royston, in Hertfordshire.
During the Napoleonic Wars the Regiment fought at the Battle of Alexandria (hence the Sphinx and the word Egypt on its colours), in the Peninsula, including Corruna, and finally at Quatre Bras and Waterloo. Its 19th century battle honours include Alma and Lucknow, and in the 1860s Queen Victoria authorised the addition of the name 'The Black Watch' to the official title of the 42nd Royal Highlanders, a title which has become known throughout the world.


During the Great War, eleven Battalions of the Black Watch fought in France and Flanders, Macedonia, Mesopotamia and Palestine. Her Majesty Queen Elizabeth, The Queen Mother, former Colonel in Chief of the Black Watch since 1937 until her death, had two brothers and a first cousin in the 5th Battalion, another brother killed in 1915 with the 8th and a cousin killed serving with 4/5th. Armistice Day found the Regiment advancing across the very field at Fontenoy where the Watch had fought 173 years before. The French commemorated the stalwart assistance given to them in Champagne in 1918 by erecting a cairn on the spot where fell the body of The Black Watch soldier who advanced the furthest - 'Here shall flourish for ever the glorious thistle of Scotland among the roses of France'.

During the Second World War the Black Watch was present at Dunkirk and fought at Crete, Tobruk, El Alamein, Sicily, Normandy, Ardennes and Burma. Indeed, its five Battalions saw service in every major theatre of war except Norway and Malaya. Its long association with Perth, Scotland, is retained by maintaining at Balhousie Castle its Headquarters and Regimental Museum. More recently the Battalion served in Hong Kong between January 1993 and August 1994 before returning to the United Kingdom and undertaking a tour of West Belfast in Northern Ireland. In July 1996 the Battalion returned home to Scotland and is currently stationed at Fort George in Inverness. In February 1997 they became the last UK Infantry Battalion to serve in Hong Kong.

BLOWBACK

Blowback is a method of operation employed in small arms. The energy required to carry out the cycle of operations being supplied to the bolt by the backward movement of the cartridge case caused by gas pressure when the round is fired, hence the bolt is blown back by the force of firing the round.
Various forms of blowback operation have been developed. Simple blowback allows for a totally unlocked breech, and relies on the mass of the breech block and the strength of the return spring to prevent the cartridge case from coming back too fast after firing. Simple blowback can only be employed in relatively low power weapons and is effectively restricted in use to pistols and sub-machineguns.

Delayed blowback is a more sophisticated form of blowback operation in which the breech is unlocked, but some mechanical delay is incorporated to ensure that the breech block does not move back too quickly. A delayed blowback operation allows the gun manufacturer to reduce the weight of the breech block relative to the weight that would be required in a simple blowback operation gun.

An expensive and sophisticated form of blowback operation employs a locked breech, allowing for the lightest possible breech block, which unlocks at the precise time to allow the residual pressure from firing to blow the breech block to the rear. This system is expensive and also sensitive to variations in ammunition.
Blowback operations are generally cheap, simple and reliable to employ and allow for a rapid barrel changing. However, they prevent power adjustment in the weapon, leave fouling in the breech and are not suitable for use in weapons mounted on vehicles.

In the first case it flies with a rotary motion and after ascending to a great height in the air, it suddenly returns in an elliptical orbit to a spot near its starting point. On throwing it downward to the ground, it rebounds in a straight line, pursuing a ricochet motion until it strikes the object at which it was thrown. The most angular curve described by it is when it is projected upward at an angle of 45 degrees, when its flight is always backward, and the thrower stands with his back to the object he intends to hit.

BOUNCING BOMB

The bouncing bomb was a rotating bomb used by the British in the Second World War to attack the Ruhr dams. The bouncing bomb was designed by Dr Barnes Wallis and derived its name from the way it 'bounced' along the surface of the water in front of the dam, rather like a stone skimmed across the surface of a pond.

The cylindrical bomb was slung beneath a Lancaster bomber and rotated prior to dropping from a carefully calculated height. It then rolled or 'bounced' along the surface of the water as far as the dam and then sank when it came into contact with the dam wall. A depth-sensitive fuse detonated the bomb at the point calculated to make the most effective breach, the water in the reservoir acting as a tamping device to direct the full force of the explosion at the dam.

BOW

Picture of Bow

A bow is a weapon for propelling arrows. It is made of a strip of flexible material, such as wood, tubular steel, fibreglass or carbon fibre and a cord. The British longbow used during the Mediaeval period by English and Welsh archers was made of yew and required an incredible 150 lbs to pull it - by comparison, modern target archery competition recurve bows have a draw weight of between 26 and 40 lbs and hunting bows rarely exceed a draw weight of 65 lbs. British bowmen were apprenticed at the age of six, and by adult hood were severely deformed with the right arm longer than the left arm, the back twisted into a hunch and the right shoulder enlarged. The British longbow could propel an arrow to a distance of 300 yards, and still penetrate a knight's armour.
British archers used various types of arrow, the popular anti-personnel arrow had a slightly barbed head of iron held on to the shaft by beeswax. These arrows were poisoned by being dipped in the earth before firing. The fletchings were cut from feathers from one side of a goose, so as to impart spin to the arrow which upon striking the target tore through the flesh with devastating effect. The combination of a barb and loose connection to the shaft ensured the tip would remain in the target even if the shaft were pulled out, and the dirt from the ground helped to ensure infection to the wound. In this way even a hit to an arm or leg would frequently result in gangrene being contracted and the victim requiring an amputation.

BOWIE KNIFE

Picture of Bowie Knife

The Bowie knife is an American, heavy, single edged sheaf knife popular in the western states. It is named after its inventor, Colonel James Bowie who wrought the blade from a file with which he had already killed his man. Originally the bowie knife had a horn handle and the blade was some fifteen inches long, and 1.25 inches wide at the hilt.

BREACHING TOWER

Picture of Breaching Tower

Breaching Towers were structures used in the sieges of mediaeval castles. They consisted of a long wooden shed fixed to a wheeled framework, with a very strong roof. From the roof hung a battering-ram which could be swung against the castle while the attackers were protected from the fire from the battlements above by the shed.

BREECH

The breech is the portion of the barrel with the chamber into which a cartridge or projectile is loaded, and the mechanism used to close the rear end of the gun. The breech withstands the rearward pressure of the propellant gases. In quick firing (QF) guns, the breech supports and extracts the cartridge case.
Research Breech

BREECH LOADING

The breech is the solid mass of metal behind the bore of a gun, and that by which the shock of the explosion is principally sustained. In breech-loading arms the charge is introduced here, there being a mechanism, by which the breech can be opened and closed. In small-arms the advantages of breech-loading for rapidity of fire, facility of cleaning, etc, recommended it to general use around the mid-19th century, and its efficacy for military purposes was effectively demonstrated by the Prussian campaigns against Denmark and Austria in 1864 and 1866. Since that time every government adopted the new system, both in small-arms and heavy ordnance, while breech-loading sporting-arms also came into general use. The chief difficulty in breech-loading is to close the breech so as to prevent the escape of the highly elastic gas to which the force of the explosion is due.

BRETECHE

A breteche or bretesche is a name common to several wooden, crenellated, and roofed erections, used in the middle agec in sieges by the assailants to afford protection while they were undermining the walls, and by the besieged to form defences behind breaches.

BREVET

A brevet is a commission giving an officer higher rank than that for which he receives pay, a type of honorary promotion of an officer. In the United States army, rank by brevet is conferred, by and with the advice and consent of the Senate, for gallant actions or meritorious services. A brevet rank gives no right of command in the particular corps to which the officer
brevetted belongs, and can be exercised only by special assignment of the President, or on court martial, and detachments composed of different corps, with pay of the brevet rank when on such duty.

BRITISH EXPEDITIONARY FORCE

The British Expeditionary Force (BEF) was the British army serving in France during the Great War and also the 1939 to 1940 army in Europe during the Second World War, which was evacuated from Dunkirk, France. In the Great War the BEF was first commanded by General J French and then General Douglas Haig. It consisted of five infantry and one cavalry division, numbering about 100,000 men. A sixth infantry division joined this force in September. The term 'BEF' strictly referred only to the forces initially sent to France in 1914, but it continued to be commonly applied to the British forces operating in France and Flanders. During the Second World War General Gort commanded the BEF sent to France in 1939. By May 1940 it consisted of 10 infantry divisions, one tank brigade, and an RAF element of about 500 fighters and light bombers. After sustaining heavy losses during the French and Belgian campaigns of 1940 the remains were evacuated from Dunkirk in June, leaving much of their equipment behind.

BROMACETONE

Bromacetone was the most widely used tear gas during the Great War and one of the most effective. It produces intolerable irritation of the eyes in concentrations of 0.01 mg/l and in heavy concentrations can be lethal while the liquid form produces extremely painful blisters on the skin. It was first used by the Germans in artillery shells and mortar bombs under the name 'B-Stoff' in 1916, it was then adopted by the French as ' Martonite' and British and American forces as 'BA'. It was abandoned by the Germans and British by the end of 1916 since its manufacture required acetone, which was required for other purposes considered more vital. The French and American armies mixed it with chloracetone and continued to use it throughout the war.
