poster from the United States In war, the word is used to describe the activity of an individual or group not associated with the military of the parties at war, such as a foreign
agent or an indigenous supporter, in particular when actions result in the destruction or damaging of a productive or vital facility, such as equipment, factories, dams, public services, storage plants or
logistic routes. Prime examples of such sabotage are the events of
Black Tom and the
Kingsland explosion. Like spies, saboteurs who conduct a military operation in civilian clothes or enemy uniforms behind enemy lines are subject to prosecution and criminal penalties instead of detention as
prisoners of war. It is common for a government in power during war or supporters of the war policy to use the term loosely against opponents of the war. Similarly, German
nationalists spoke of a
stab in the back having cost them the loss of World War I. A modern form of sabotage is the distribution of
software intended to damage specific industrial systems. For example, the U.S.
Central Intelligence Agency (CIA) is alleged to have sabotaged a Siberian pipeline during the
Cold War, using information from the
Farewell Dossier. A more recent case may be the
Stuxnet computer worm, which was designed to subtly infect and damage specific types of industrial equipment. Based on the equipment targeted and the location of infected machines, security experts believe it was an attack on the
Iranian
nuclear program by the
United States or
Israel. Sabotage, done well, is inherently difficult to detect and difficult to trace to its origin. During
World War II, the U.S.
Federal Bureau of Investigation (FBI) investigated 19,649 cases of sabotage and concluded the enemy had not caused any of them. Sabotage in warfare, according to the
Office of Strategic Services (OSS)
Simple Sabotage Field Manual, varies from highly technical
coup de main acts that require detailed planning and specially trained operatives, to innumerable simple acts that ordinary citizen-saboteurs can perform. Simple sabotage is carried out in such a way as to involve a minimum danger of injury, detection, and
reprisal. There are two main methods of sabotage: physical destruction and the "human element". While physical destruction as a method is self-explanatory, its targets are nuanced, reflecting objects to which the saboteur has normal and inconspicuous access in everyday life. The "human element" is based on universal opportunities to make faulty decisions, to adopt a non-cooperative attitude, and to induce others to follow suit. There are many examples of physical sabotage in wartime. However, one of the most effective uses of sabotage is against organizations. The OSS manual provides numerous techniques under the title "General Interference with Organizations and Production": • When possible, refer all matters to committees for "further study and consideration". Attempt to make the committees as large as possible—never fewer than five • Bring up irrelevant issues as frequently as possible. • Haggle over precise wordings of communications, minutes, resolutions. • In making work assignments, always sign out unimportant jobs first, assign important jobs to inefficient workers with poor machines. • Insist on perfect work in relatively unimportant products; send back for refinishing those with the least flaw. Approve other defective parts whose flaws are not visible to the naked eye. • To lower morale, and with it, production, be pleasant to inefficient workers; give them undeserved promotions. Discriminate against efficient workers; complain unjustly about their work. • Hold meetings when there is more critical work to be done. • Multiply procedures and clearances involved in issuing instructions, paychecks, and so on. See that multiple people must approve everything where one would do. • Spread disturbing rumors that sound like inside information. From the section entitled, "General Devices for Lowering Morale and Creating Confusion" comes the following quintessential simple sabotage advice: "Act stupid." On 12 February 1917,
Bedouins allied with the British destroyed a Turkish railroad near the port of
Wajh,
derailing a Turkish locomotive. The Bedouins traveled by camel and used explosives to demolish a portion of track.
Post World War I experts inspect the scene of the "railway sabotage" on the
South Manchurian Railway in 1931. The "railroad sabotage" was one of the events that led to the
Mukden Incident and the Japanese occupation of
Manchuria. In Ireland, the
Irish Republican Army (IRA) used sabotage against the British following the
Easter 1916 uprising. The IRA compromised communication lines and lines of transportation and fuel supplies. The IRA also employed passive sabotage, with dock and railroad workers refusing to work on ships and rail cars used by the government. In 1920, agents of the IRA committed arson against at least fifteen British warehouses in Liverpool. The following year, the IRA set fire to numerous British targets again, including the
Dublin Customs House, this time sabotaging most of Liverpool's firetrucks in the firehouses before lighting the matches.
In World War II World War II-era poster warning against sabotage
Lieutenant Colonel George T. Rheam was a British soldier, who ran
Brickendonbury Manor from October 1941 to June 1945 during
World War II, which was Station XVII of the
Special Operations Executive (SOE), which trained specialists for the SOE. Rheam innovated many sabotage techniques and is considered by
M. R. D. Foot the "founder of modern industrial sabotage." from March 8, 9 and 10 1944 of derailment tests done on the
Claiborne-Polk Military Railroad. The tests were done to better train allied personnel in acts of
rail sabotage during
World War 2. Sabotage training for the
Allies consisted of teaching would-be saboteurs' key components of working machinery to destroy. "Saboteurs learned hundreds of small tricks to cause the Germans big trouble. The cables in a telephone junction box ... could be jumbled to make the wrong connections when numbers were dialed. A few ounces of
plastique, properly placed, could bring down a bridge, cave in a mine shaft, or collapse the roof of a railroad tunnel." The Polish Home Army
Armia Krajowa, which commanded the majority of resistance organizations in Poland (even the National Forces, except the
Military Organization Lizard Union; the Home Army also included the
Polish Socialist Party – Freedom, Equality, Independence) and coordinated and aided the
Jewish Military Union as well as more reluctantly helping the
Jewish Combat Organization, was responsible for the greatest number of acts of sabotage in German-occupied Europe. The Home Army's sabotage operations
Operation Garland and
Operation Ribbon are just two examples. In all, the Home Army damaged 6,930 locomotives, set 443 rail transports on fire, damaged over 19,000 rail cars, and blew up 38 rail bridges, not to mention the attacks against the railroads. The Home Army was also responsible for 4,710 built-in flaws in parts for aircraft engines and 92,000 built-in flaws in artillery projectiles, among other examples of significant sabotage. In addition, over 25,000 acts of more minor sabotage were committed. It continued to fight against both the Germans and the Soviets; however, it did aid the Western Allies by collecting constant and detailed information on the German rail, wheeled, and horse transports. As for Stalin's proxies, their actions led to a great number of the Polish and Jewish hostages, mostly civilians, being murdered in reprisal by the Germans. The
Gwardia Ludowa destroyed around 200 German trains during the war, and indiscriminately threw hand grenades into places frequented by Germans. The
French Resistance ran an extremely effective sabotage campaign against the Germans during World War II. Receiving their sabotage orders through messages over the
BBC radio or by aircraft, the French used both passive and active forms of sabotage. Passive forms included losing German shipments and allowing poor quality material to pass factory inspections. Many active sabotage attempts were against critical rail lines of transportation. German records count 1,429 instances of sabotage from French Resistance forces between January 1942 and February 1943. From January through March 1944, sabotage accounted for three times the number of locomotives damaged by Allied air power. In December 1944, the Germans ran a
false flag sabotage infiltration,
Operation Greif, which was commanded by
Waffen-SS commando Otto Skorzeny during the
Battle of the Bulge. German
commandos, wearing
US Army uniforms, carrying
US Army weapons, and using US Army vehicles, penetrated US lines to spread panic and confusion among US troops and to blow up bridges,
ammunition dumps, and fuel stores and to disrupt the lines of communication. Many of the commandos were captured by the Americans. Because they were wearing US uniforms, a number of the Germans were executed as spies, either
summarily or after
military commissions.
After World War II 's K class 2-8-4T steam locomotive and freight train on the Jaffa and Jerusalem line after being sabotaged by
Jewish paramilitary forces in 1946. From 1948 to 1960, the
Malayan Communists committed numerous effective acts of sabotage against the British Colonial authorities, first targeting railway bridges, then hitting larger targets such as military camps. Most of their efforts were intended to weaken
Malaysia's colonial economy and involved sabotage against trains, rubber trees, water pipes, and electric lines. The Communists' sabotage efforts were so successful that they caused backlash among the Malaysian population, who gradually withdrew support for the Communist movement as their livelihoods became threatened. In
Mandatory Palestine from 1945 to 1948, Jewish groups opposed British control. Though that control was to end according to the
United Nations Partition Plan for Palestine in 1948, the groups used sabotage as an opposition tactic. The
Haganah focused their efforts on camps used by the British to hold refugees, and radar installations that could be used to detect illegal immigrant ships. The
Stern Gang and the
Irgun used terrorism and sabotage against the British government and against lines of communications. In November 1946, the Irgun and Stern Gang attacked a railroad twenty-one times in a three-week period, eventually causing shell-shocked Arab railway workers to strike. The
6th Airborne Division was called in to provide security as a means of ending the strike. One of the more famous sabotage operations undertaken by EOKA was at
RAF Akrotiri where 3 members of the organisation entered the base and placed multiple bombs undetected, destroying 4
English Electric Canberra aircraft and one
de Havilland Venom aircraft.
In Vietnam The
Viet Cong used swimmer saboteurs often and effectively during the
Vietnam War. Between 1969 and 1970, swimmer saboteurs sunk, destroyed, or damaged 77 assets of the U.S. and its allies. Viet Cong swimmers were poorly equipped but well-trained and resourceful. The swimmers provided a low-cost/low-risk option with high payoff; possible loss to the country for failure compared to the possible gains from a successful mission led to the obvious conclusion the swimmer saboteurs were a good idea.
During the Cold War On 1 January 1984, the
Cuscatlán Bridge over the
Lempa river in
El Salvador, critical to the flow of commercial and military traffic, was destroyed by guerrilla forces using explosives after using mortar fire to "scatter" the bridge's guards, causing an estimated $3.7 million in required repairs, and considerably impacting on El Salvadoran business and security. In 1982 in
Honduras, a group of nine Salvadorans and Nicaraguans destroyed a main electrical power station, leaving the capital city
Tegucigalpa without power for three days. == As crime ==
