The Battle of Verdun was fought from 21 February to 18 December 1916 on the Western Front in France. The battle was the longest of the First World War and took place on the hills north of Verdun-sur-Meuse. The German 5th Army attacked the defences of the Fortified Region of Verdun and those of the French Second Army on the right (east) bank of the Meuse. Using the experience of the Second Battle of Champagne in 1915, the Germans planned to capture the Meuse Heights, an excellent defensive position, with good observation for artillery-fire on Verdun. The Germans hoped that the French would commit their strategic reserve to recapture the position and suffer catastrophic losses at little cost to the German infantry.
A flamethrower is a ranged incendiary device designed to project a controllable jet of fire. First deployed by the Byzantine Empire in the 7th century AD, flamethrowers saw use in modern times during World War I, and more widely in World War II as a tactical weapon against fortifications.
Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which combatants are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. It became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.
Technology during World War I (1914–1918) reflected a trend toward industrialism and the application of mass-production methods to weapons and to the technology of warfare in general. This trend began at least fifty years prior to World War I during the American Civil War of 1861–1865, and continued through many smaller conflicts in which soldiers and strategists tested new weapons.
The first day on the Somme was the beginning of the Battle of Albert (1–13 July) the name given by the British to the first two weeks of the Battle of the Somme in the First World War. Nine corps of the French Sixth Army and the British Fourth and Third armies attacked the German 2nd Army. The attack was from Foucaucourt south of the Somme, northwards across the Somme and the Ancre to Serre and Gommecourt, 2 mi (3.2 km) beyond, in the Third Army area. The objective of the attack was to capture the German first and second defensive positions from Serre south to the Albert–Bapaume road and the first position from the road south to Foucaucourt.
Stormtroopers were specialist infantrymen of the Imperial German Army. In the last years of World War I, Stoßtruppen were trained to use infiltration tactics – part of the Germans' improved method of attack on enemy trenches. The German Empire entered the war certain that the conflict would be won in the course of great military campaigns, thus relegating results obtained during individual clashes to the background; consequently the best officers, concentrated in the German General Staff, placed their attention on maneuver warfare and the rational exploitation of railways, rather than concentrating on the conduct of battles. This attitude made a direct contribution to operational victories of Germany in Russia, Romania, Serbia and Italy, but it resulted in failure in the West. Thus the German officers on the Western Front found themselves in need of resolving the static situation caused by trench warfare on the battlefield.
Richard Fiedler was a German scientist who invented the modern flamethrower. This is a weapon that projects a stream of nitrogen. He submitted evaluation models of his Flammenwerfer to the German Army in 1901. The most significant model submitted was a man-portable device, consisting of a vertical single cylinder 4 feet long, horizontally divided in two, with pressurized gas in the lower section and flammable oil in the upper section. On depressing a lever the propellant gas forced the flammable oil into and through a rubber tube and over a simple igniting wick device in a steel nozzle. The weapon projected a jet of fire and enormous clouds of smoke some 20 yards. It was a single-shot weapon - for burst firing, a new igniter section was attached each time it was used for battle or other uses of any sorts. It was first used on the western front both by the Central Powers and the Entente.
The Flamethrower, Portable, No 2, also known as the Ack Pack, was a British design of flamethrower for infantry use in the Second World War.
The Flammenwerfer 35, or FmW 35 was a one-man German flamethrower used during World War II to clear out trenches and buildings. It could project fuel up to 25 meters from the user.
The Einstossflammenwerfer 46 was a handheld single shot flamethrower designed in Germany during the second half of World War II and introduced in 1944; it was engineered to be both cheap and easily mass-produced, falling into the category of throwaway flamethrower. The disposable weapon fired a half-second burst of flame of up to 27 metres (89 ft). It was issued to the Volkssturm or the Werwolf movement, but also used by the Fallschirmjäger . It was inspired by the Italian "Lanciafiamme Mod. 41 d'assalto".
The first series of German man-portable flamethrower was called the Kleinflammenwerfer or "Kleif". Fuel oil was stored in a large vertical, cylindrical backpack container. High-pressure propellant was typically stored in another, smaller container within the fuel tank or attached externally depending on model. Most iterations of the Kleif used a long hose which was covered in linen and corrugated by steel wire to prevent kinks and punctures. The hose connected to the fuel tank and fed into a lance tube with an igniting device at the nozzle. With the turn of a valve at the tank, the propellant forced the fuel through the hose and towards the lance. When the lance operator was ready, a second "firing" valve was opened, sending the fuel oil to the igniting device at the nozzle and propelling the burning fuel oil outward. The flamethrower was operated by two soldiers, one carrying the fuel and propellant tanks, another wielding the lance. Contrary to popular culture, the Kleif was too unwieldy to be used effectively by a single operator. The Wechselapparat, a smaller and more refined replacement for the Kleif, was introduced in May 1917.
The Wechselapparat M.1917 (Wex) was a World War I German flamethrower introduced in early May of 1917 to replace the earlier Kleif. It was developed by engineer workshops within the Guards Reserve Pioneer Regiment (Garde-Reserve-Pionier-Regiment), which was the main flamethrower unit of the Imperial German Army. It was the first flamethrower in the German arsenal which could be used by one soldier if needed. The Wex was deployed in a group of four: two operators, one officer, and a grenadier. It had a doughnut-shaped backpack fuel container with a spherical propellant container (nitrogen) in the middle that propelled the flame oil. A corrugated rubber hose led from the tank to a brass stopcock that enables the tank carrier to release the fuel under pressure to the lance which has a brass stopcock for firing. The Wex used a magnesium based igniter system which was held in a housing around the nozzle. When inserted into the housing, the igniter is pressed against a spring and then held in place by a hinged metal fork on the housing. Once the igniter was spent, the fork was removed and the igniter was ejected by the spring. The Wex was used from 1917 until the end of the war in 1918. It saw use in the German Revolution of 1918-1919 by the Friekorps and Reichswehr. Some Wex flamethrowers survived the Revolution despite the Treaty of Versailles and have been used by the Finnish and the Polish armies in the 1920s. The design may have inspired the later Flammenwerfer 40.
The Grossflammenwerfer or Grof is a large flamethrower, designed to be used from the trenches. In addition to man-portable units, the Germans designed heavy flamethrowers before and during the First World War. The fuel and propellant containers were too large and heavy for mobility, but the hose could be long enough to be carried out of the trenches closer to the enemy. Multiple propellant and fuel containers could be connected together to improve range and usage time.
The M1 and M1A1 were portable flamethrowers developed by the United States during World War II. The M1 weighed 72 lb, had a range of 15 meters, and had a fuel tank capacity of five gallons. The improved M1A1 weighed less, at 65 lb, had a much longer range of 45 meters, had the same fuel tank capacity, and fired thickened fuel (napalm).
Livens Large Gallery Flame Projectors were large experimental flamethrowers used by the British Army in World War I, named after their inventor, Royal Engineers officer William Howard Livens.
The Flammenwerfer 41, or FmW 41 was the standard German flamethrower beginning in 1941 and an upgraded version of the earlier Flammenwerfer 35, whose main issue was its excessive weight of 36kg, with the Flammenwerfer 41 being only 18. It performed a similar role of other flamethrowers of the time, namely clearing enemy trenches and buildings in highly fortified areas. From 1942 to April 1945, 64,284 examples were produced. After 1945, flamethrowers steadily decreased in usage globally, with the Bundeswehr not using any.
Willy Martin Ernst Rohr was a German Army officer who was a major contributor to the development of infantry tactics in World War I, particularly for the system of Storm Battalions.
Assault Battalion No. 5 (Rohr), was an experimental infantry battalion of the Imperial German Army during World War I. Under command of its namesake, Hauptmann Willy Rohr, it became known for its innovations in infantry tactics that would give rise to the German Stoßtruppen. The battalion began as a combat engineer detachment of the 8th Army Corps, part of a larger effort among German commanders to try and gain the tactical upper hand following the strategic and operational stagnation of trench warfare on the Western Front of World War I. The unit pioneered what would later be referred to as Stoßtrupptaktik, a body of field tactics taught to every subsequent German assault unit.
The Mortier de 58 T N°1 sometimes referred to as Lance Torpilles was an early French medium trench mortar of World War I. Built in small numbers it was a transitional type in the development of later French mortars.
The Lanciafiamme Mod. 41 d'assalto was an flamethrower used by the Royal Italian Army during World War II. The mod. 41 was meant to be an extremely light and compact flamethrower to equip paratroopers and Assault Engineers, The flamethrower remained in use after the war until 1998.
