The explosive rat, [1] also known as a rat bomb, [2] was a weapon developed by the British Special Operations Executive (SOE) in World War II for use against Germany. Rat carcasses were filled with plastic explosives, and were to be distributed near German boiler rooms where it was expected they would be disposed of by burning, with the subsequent explosion having a chance of causing a boiler explosion.
The explosive rats never saw use, as the first shipment was intercepted by the Germans; however, the resulting search for more booby trapped rats consumed enough German resources for the SOE to conclude that the operation was a success.
During World War II, the British Special Operations Executive (SOE) procured about a hundred rodents, ostensibly for medical experiments. [3] [4] The rodents were killed and plastic explosives sewn inside them. [3]
The idea, developed in 1941, [5] was that when the dead rat was discovered in the boiler room of a locomotive, factory, power station, or similar installation, the stoker tending the boiler would dispose of the unpleasant discovery by shoveling it into the furnace, causing the booby trapped rat to explode. [1] [3] [6] A rat could contain only a small amount of explosive; however, a penetration of a highly pressurized steam boiler could trigger a devastating boiler explosion. [3] A rat bomb could also be set with a delayed fuse. [2]
The first shipment of carcasses was intercepted by the Germans, and the SOE plan was dropped. [3] The Germans exhibited the rats at top military schools and conducted searches for further exploding rats. [3] The SOE concluded: "The trouble caused to them was a much greater success to us than if the rats had actually been used." [3]
A biography of Station IX officer J. Elder Wills claims that nine boilers were damaged in Belgian factories by the rats but is probably a myth. [7]
Special Operations Executive (SOE) was a British organisation formed in 1940 to conduct espionage, sabotage and reconnaissance in German-occupied Europe and to aid local resistance movements during World War II.
A car bomb, bus bomb, van bomb, lorry bomb, or truck bomb, also known as a vehicle-borne improvised explosive device (VBIED), is an improvised explosive device designed to be detonated in an automobile or other vehicles.
A booby trap is a device or setup that is intended to kill, harm or surprise a human or another animal. It is triggered by the presence or actions of the victim and sometimes has some form of bait designed to lure the victim towards it. The trap may be set to act upon trespassers that enter restricted areas, and it can be triggered when the victim performs an action. It can also be triggered by vehicles driving along a road, as in the case of improvised explosive devices (IEDs).
An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional military action. It may be constructed of conventional military explosives, such as an artillery shell, attached to a detonating mechanism. IEDs are commonly used as roadside bombs, or homemade bombs.
The tunnel rats were American, Australian, New Zealand, and South Vietnamese soldiers who performed underground search and destroy missions during the Vietnam War.
The tunnels of Củ Chi are an immense network of connecting tunnels located in the Củ Chi District of Ho Chi Minh City (Saigon), Vietnam, and are part of a much larger network of tunnels that underlie much of the country. The Củ Chi tunnels were the location of several military campaigns during the Vietnam War, and were the Viet Cong's base of operations for the Tết Offensive in 1968.
The Norwegian heavy water sabotage was a series of Allied-led efforts to halt German heavy water (deuterium) production via hydroelectric plants in Nazi Germany-occupied Norway during World War II, involving both Norwegian commandos and Allied bombing raids. During the war, the Allies sought to inhibit the German development of nuclear weapons with the removal of heavy water and the destruction of heavy-water production plants. The Norwegian heavy water sabotage was aimed at the 60 MW Vemork power station at the Rjukan waterfall in Telemark.
The Israeli Combat Engineering Corps is part of the Israel Defense Forces with responsibility for mobility assurance, road breaching, defense and fortifications, counter-mobility of enemy forces, construction and destruction under fire, sabotage, explosives, bomb disposal, counter-weapons of mass destruction (NBC) and special engineering missions.
The explosion of animals is an uncommon event arising from natural causes or human activity. Among the best known examples are the post-mortem explosion of whales, either as a result of natural decomposition or deliberate attempts at carcass disposal. Other instances of exploding animals are defensive in nature or the result of human intervention.
The Justice Department (JD) was founded in the United Kingdom by animal liberation activists who declared they were willing to use a diversity of tactics up to and including violence against their opponents. Calling for "abusers to have but a taste of the fear and anguish their victims suffer on a daily basis", activists distanced themselves from the Animal Liberation Front's (ALF) guidelines of non-violent resistance.
Military animals are trained animals that are used in warfare and other combat related activities. As working animals, different military animals serve different functions. Horses, elephants, camels, and other animals have been used for both transportation and mounted attack. Pigeons were used for communication and photographic espionage. Many other animals have been reportedly used in various specialized military functions, including rats and pigs. Dogs have long been employed in a wide variety of military purposes, more recently focusing on guarding and bomb detection, and along with dolphins and sea lions are in active use today.
A limpet mine is a type of naval mine attached to a target by magnets. It is so named because of its superficial similarity to the shape of the limpet, a type of sea snail that clings tightly to rocks or other hard surfaces.
The coal torpedo was a hollow iron casting filled with explosives and covered in coal dust, deployed by the Confederate Secret Service during the American Civil War, and intended for doing harm to Union steam transportation. When it was shoveled into the firebox amongst the coal, the resulting explosion would at the very least damage the boiler and render the engines inoperable. At worst, a catastrophic boiler explosion would kill crewmen and passengers, start a fire, or even sink the vessel.
An anti-handling device is an attachment to or an integral part of a landmine or other munition such as some fuze types found in general-purpose air-dropped bombs, cluster bombs and sea mines. It is designed to prevent tampering or disabling, or to target bomb disposal personnel. When the protected device is disturbed, it detonates, killing or injuring anyone within the blast area. There is a strong functional overlap of booby traps and anti-handling devices.
In military munitions, a fuze is the part of the device that initiates its function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams.
Major Cecil Vandepeer Clarke MC (1897–1961) was an engineer, inventor and soldier who served in both the First and Second World Wars.
Operation Postmaster was a British special operation conducted on the Spanish island of Fernando Po, now known as Bioko, off West Africa in the Gulf of Guinea, during the Second World War. The mission was carried out by the Small Scale Raiding Force (SSRF) and the Special Operations Executive (SOE) in January 1942. Their objective was to board the Italian and German ships in the harbour and sail them to Lagos. The SSRF under the command of Major Gus March-Phillipps left Britain in August 1941 and sailed the Brixham trawler, Maid of Honour, to the Spanish colony.
Animal-borne bomb attacks are the use of animals as delivery systems for explosives. The explosives are strapped to a pack animal such as a horse, mule or donkey. The pack animal may be set off in a crowd.
Operation Josephine B was a military mission in June 1941 during the Second World War. The mission was organised jointly by the Free French and the British Special Operations Executive (SOE), together with the Royal Air Force for air drops. The operation was initially stalled by a lack of up-to-date information, but ultimately succeeded in its main objective, the destruction of an electrical transformer station in Pessac, near Bordeaux.
Aston House was a prominent 17th-century residence with large parkland situated opposite the parish church in Aston, Hertfordshire in southern England. The house was demolished in 1961 by the Stevenage New Town Development Corporation after occupying it as its initial HQ. The site was developed and named Yeomans Drive in memory of Arthur Yeomans, the last owner in 1939 when it was requisitioned by the War Office. The adjoining parkland became Stevenage Golf and Conference Centre in April 1980.
