Frederick Marten Hale (1864 – 2 February 1931) was a British explosives engineer and inventor. After education at the Devon County School and in Brussels, Belgium, Hale worked in hydraulic and fire engineering. He became involved in the design and manufacture of explosives from 1895 and rose to positions at the Cotton Powder Company and the Roburite & Ammonal company. Hale saw the successful use of hand grenades in the 1904–05 Russo-Japanese War and designed his own grenade in 1906. This was rejected by the War Office but during the 1914–1918 First World War it was used by the British Army as the No. 2 grenade.
Hale became the predominant British designer of grenades in the pre-war era. He developed the Hales rifle grenade which was exported to several states but did not see extensive use until the First World War. With the coming of trench warfare the army requested large quantities. Hale struggled to meet these demands owing to its complicated design and fuse, which was manufactured by Dynamit Nobel. Hale refined his design three times during the war to make it simpler, safer and more reliable. Some 10 million were used during the war. Hale also developed an aircraft bomb, which was used successfully by British aircraft against German Zeppelin airships on the ground and in the air, and a depth charge. After the war he successfully sued the British government for infringing his rifle grenade patents.
Frederick Marten Hale was born in Bristol in 1864, the son of Matthew Henry Hale. He received an education at Devon County School in West Buckland and in Brussels, Belgium. [1] Hale initially specialised in hydraulic engineering and fire engineering. After four years, in 1895, he switched to the design and manufacture of explosives. [2] He became a director of the Cotton Powder Company and also controlled the Roburite & Ammonal company, both of which manufactured explosives for use in mining and warfare. [3] : 34, 81 Hale lived at Bromley in Kent. He was a member of the Junior Constitutional Club, the Bromley and County Club and Sundridge Park Golf Club. [1]
The British War Office had declared hand grenades obsolete in 1902 and ceased work on modern versions. [3] : 32 However Japanese troops used the weapons to good effect during the 1904-05 Russo-Japanese War, a fact reported by a British military observer Lieutenant Colonel Aylmer Haldane who also brought back an example of the grenades used. The War Office determined that the weapons might be useful in assaulting fortresses and the Royal Laboratory was commissioned to produce an example. The Laboratory's struggled to replicate the Japanese design but in 1906 produced a version which became the No. 1 grenade. After testing it was considered to be somewhat overengineered but was adopted by the army in 1908. Production was low and only 420 were produced by the start of the First World War in 1914. [3] : 34
During this period Hale also became interested in grenades. He may have been inspired by reports of the weapon's use in Manchuria or have viewed Haldane's example. It is also known that Hale discussed grenades with a Japanese army officer at some point between 1906 and 1908. Hale patented his grenade, which would eventually become the British Army's No. 2 grenade, in 1906. The War Office considered it inferior to the No. 1 grenade and thought it was more liable to misfire. Hales made a number of improvements to his design and demonstrated it to the Chief Superintendent of the Ordnance Factories at the Cotton Powder Company's Faversham works in 1908. It was again rejected, this time as it was considered too difficult to throw in a trench. The No. 1 grenade had the same drawback and the War Office seems to have rejected Hale's design as the No.1, being designed and manufactured in house, was cheaper to produce. With the outbreak of the war in 1914 the army, short of any alternatives, adopted the No. 2 grenade. [3] : 34
With little War Office interest in the field in the pre-war years Hale came to dominate grenade development. He was granted 11 patents for hand grenades and rifle grenades between 1906 and the start of the First World War. [3] : 38 He developed the Hales rifle grenade in 1908 and marketed it widely, demonstrating the weapon to representatives from 18 countries including France, Germany, Russia, Mexico and Spain. [3] : 38 [1] It was dismissed by the chief draftsman at the Woolwich Arsenal as "a crazy and audacious monstrosity" that was likely to burst rifle barrels. [4] Hale sold a number of grenades to Germany in 1911 but they were not selected for service. [3] : 38 He exported the rifle grenade to government of Mexico where they were used during the Mexican Revolution, and to Brazil leading to an association of the weapon with suppression of disorder and with colonial warfare. [3] : 38 [5] By 1911 Hale had modified the grenade to incorporate a wind vane. [3] : 108 The grenade would not detonate unless the wind vane was activated by flight, avoiding the danger of a grenade detonating in front of the user after falling off the rifle. [6]
Hale's rifle grenade was accepted by the British Army in 1913 but by the start of the First World War only a single box of 50 grenades was on hand. [4] It was the only rifle grenade available to the British Army at that point of the war. [1] The army did not make great use of the weapon until the rise of trench warfare on the Western Front. [3] : 39 With increased demand Hale manufactured the grenade at both the Cotton Powder Company and Roburite & Ammonal. [3] : 81 The detonators, however, were manufactured by Dynamit Nobel and their availability limited Hale's production outputs. [3] : 86 Hale's grenade was also complex to manufacture and its machined steel body took longer to produce than a simple cast iron one would. By 1915 the weapon was still only available in small quantities. [3] : 118
Hale's dominance of the field in the pre-war years had led to a lack of work by competitors so alternatives were not forthcoming. [3] : 118 During the war the Royal Laboratory failed to produce a rifle grenade that could compete with Hale's. [3] : 51 The army's field workshops, under Captain Henry Newton, had more success and from 1915 manufactured a number of No. 22 grenades (Newton-Pippin rifle grenades). These were made from cast iron and scrap brass and cost just two shillings each, compared to 25 shillings for the Hales grenade. [3] : 102 The Newton-Pippin was also more lethal as it did not penetrate into the ground as far before detonating, increasing the effect of its shrapnel, and was top-heavy increasing the likelihood of it landing head first and activating the detonator. [3] : 118, 122–123 The Newton Pippin was simpler and had only one moving part in its fuse. [3] : 118 Despite this production was lower than the Hale's grenade, of which 10 million were used during the war. [1] [3] : 108
Hale developed refinements to his rifle grenade design throughout the war. The original (the No. 3) was replaced by the No. 20 in March 1916 and that by the No. 24 in 1917 and that by the No. 35 in early 1918. Each successive model was simpler, safer and more reliable than its predecessor. They were also quicker and easier to manufacture and consumed less brass and steel. [3] : 132
In 1913 Hale invented the Hale aircraft bomb. It was the only aerial bomb available to British forces at the start of the First World War. [1] In October 1914 Hale bombs were used in a raid on an airship base in Düsseldorf, Germany. Flight Lieutenant Reginald Marix hit a shed and destroyed Zeppelin LZ 25 , the first time a Zeppelin had been destroyed whilst still in its hangar. [1] On 7 June 1915 a Hale bomb was used by Flight Sub-Lieutenant Reginald Warneford to destroy Zeppelin LZ 37 over Ghent, Belgium, the first time a Zeppelin had been brought down by an aircraft. [1] [7] Hale sent a silver replica of a 20 lb (9 kg) Hale aircraft bomb to the Air Department to commemorate the event. [7] A Hale bomb was also used in the first sinking of a U-boat by an aircraft and hundreds of thousands were dropped during the war. [1] Hale also developed the first depth charge for use by the Royal Navy to attack U-boats in November 1914. [1]
After the war Hale fought a legal action against the War Office for infringement of his patents for rifle grenades. The action was launched on 3 May 1921 and was settled in Hale's favour in the Court of Appeal on 16 May 1925. [7] [8] Hale died on 2 February 1931 at Torquay in Devon. [9]
A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia.
Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace black powder as a military propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun.
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions, but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short.
Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13.2mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft.
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.
Technology played a significant role in World War II. Some of the technologies used during the war were developed during the interwar years of the 1920s and 1930s, much was developed in response to needs and lessons learned during the war, while others were beginning to be developed as the war ended. Many wars had major effects on the technologies that we use in our daily lives. However, compared to previous wars, World War II had the greatest effect on the technology and devices that are used today. Technology also played a greater role in the conduct of World War II than in any other war in history, and had a critical role in its outcome.
A shell, in a military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. Modern usage sometimes includes large solid kinetic projectiles, which are more properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used.
"Mills bomb" is the popular name for a series of British hand grenades which were designed by William Mills. They were the first modern fragmentation grenades used by the British Army and saw widespread use in the First and Second World Wars.
Stielhandgranate is the German term for "stick hand grenade" and generally refers to a prominent series of World War I and World War II-era German stick grenade designs, distinguished by their long wooden handles, pull cord arming and cylindrical warheads. The first models were introduced by the Imperial German Army during World War I and the final design was introduced during World War II by the German Wehrmacht.
A rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade were thrown by hand.
The Stokes mortar was a British trench mortar designed by Sir Wilfred Stokes KBE that was issued to the British and U.S. armies, as well as the Portuguese Expeditionary Corps, during the latter half of the First World War. The 3-inch trench mortar is a smooth-bore, muzzle-loading weapon for high angles of fire. Although it is called a 3-inch mortar, its bore is actually 3.2 inches or 81 mm.
The Newton 6-inch mortar was the standard British medium mortar in World War I from early 1917 onwards.
The 2 inch medium trench mortar, also known as the 2-inch howitzer, and nicknamed the "toffee apple" or "plum pudding" mortar, was a British smooth bore muzzle loading (SBML) medium trench mortar in use in World War I from mid-1915 to mid-1917. The designation "2-inch" refers to the mortar barrel, into which only the 22-inch bomb shaft but not the bomb itself was inserted; the spherical bomb itself was actually 9 inches (230 mm) in diameter and weighed 42 lb (19 kg), hence this weapon is more comparable to a standard mortar of approximately 5-6 inch bore.
The Mortier de 58 mm type 2 or Mortier de 58 mm T N°2, also known as the Crapouillot or "little toad" from its appearance, was the standard French medium trench mortar of World War I.
William Howard Livens, was an engineer, a soldier in the British Army and an inventor particularly known for the design of chemical warfare and flame warfare weapons. Resourceful and clever, Livens' successful creations were characterised by being very practical and easy to produce in large numbers. In an obituary, Sir Harold Hartley said "Livens combined great energy and enterprise with a flair for seeing simple solutions and inventive genius."
A grenade is an explosive weapon typically thrown by hand, but can also refer to a shell shot from the muzzle of a rifle or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and a safety lever secured by a cotter pin. The user removes the safety pin before throwing, and once the grenade leaves the hand the safety lever gets released, allowing the striker to trigger a primer that ignites a fuze, which burns down to the detonator and explodes the main charge.
The British Army used a variety of standardized battle uniforms and weapons during World War I. According to the British official historian Brigadier James E. Edmonds writing in 1925, "The British Army of 1914 was the best trained best equipped and best organized British Army ever sent to war". They were the only army to wear any form of a camouflage uniform; the value of drab clothing was quickly recognised by the British Army, who introduced Khaki drill for Indian and colonial warfare from the mid-19th century on. As part of a series of reforms following the Second Boer War, a darker khaki serge was adopted in 1902, for service dress in Britain itself. The British military authorities showed more foresight than their French counterparts, who retained highly visible blue coats and red trousers for active service until the final units received a new uniform over a year into World War I. The soldier was issued with the 1908 Pattern Webbing for carrying personal equipment, and he was armed with the Short Magazine Lee–Enfield rifle.
The Hales rifle grenade is the name for several rifle grenades used by British forces during World War I. All of these are based on the No. 3 design.
The No. 2 grenade is a percussion cap fragmentation and rifle grenade used by the United Kingdom during World War I.
The kleineGranatenwerfer 16 or Gr.W.16(Small Grenade Launcher Model 1916) in English, was an infantry mortar used by the Central Powers during the First World War. It was designed by a Hungarian priest named Father Vécer and was first used by the Austro-Hungarian Army in 1915. In Austro-Hungarian service, they received the nickname "Priesterwerfers". In 1916 Germany began producing a modified version under license for the Imperial German Army.
