Although the term "guerrilla warfare" was coined in the context of the Peninsular War in the 19th century,[2] the tactical methods of guerrilla warfare have long been in use. In the 6th century BC, Sun Tzu proposed the use of guerrilla-style tactics in The Art of War. The 3rd century BC Roman general Quintus Fabius Maximus Verrucosus is also credited with inventing many of the tactics of guerrilla warfare through what is today called the Fabian strategy, and in China Peng Yue is also often regarded as the inventor of guerilla warfare. Guerrilla warfare has been used by various factions throughout history and is particularly associated with revolutionary movements and popular resistance against invading or occupying armies.
Guerrilla tactics focus on avoiding head-on confrontations with enemy armies, typically due to inferior arms or forces, and instead engage in limited skirmishes with the goal of exhausting adversaries and forcing them to withdraw (see also attrition warfare). Organized guerrilla groups often depend on the support of either the local population or foreign backers who sympathize with the guerrilla group's efforts.
Etymology
Spanish guerrilla resistance to the Napoleonic French invasion of Spain at the Battle of Valdepeñas
The Spanish word guerrilla is the diminutive form of guerra ("war"); hence, "little war". The term became popular during the early-19th century Peninsular War, when, after the defeat of their regular armies, the Spanish and Portuguese people successfully rose against the Napoleonictroops and defeated a highly superior army using the guerrilla strategy in combination with a scorched earth policy and people's war (see also attrition warfare against Napoleon). In correct Spanish usage, a person who is a member of a guerrilla unit is a guerrillero ([geriˈʎeɾo]) if male, or a guerrillera ([geriˈʎeɾa]) if female. Arthur Wellesley adopted the term "guerrilla" into English from Spanish usage in 1809,[2] to refer to the individual fighters (e.g., "I have recommended to set the Guerrillas to work"), and also (as in Spanish) to denote a group or band of such fighters. However, in most languages guerrilla still denotes a specific style of warfare. The use of the diminutive evokes the differences in number, scale, and scope between the guerrilla army and the formal, professional army of the state.[3]
Prehistoric tribal warriors presumably employed guerrilla-style tactics against enemy tribes:
Primitive (and guerrilla) warfare consists of war stripped to its essentials: the murder of enemies; the theft or destruction of their sustenance, wealth, and essential resources; and the inducement in them of insecurity and terror. It conducts the basic business of war without recourse to ponderous formations or equipment, complicated maneuvers, strict chains of command, calculated strategies, timetables, or other civilized embellishments.[4]
Evidence of conventional warfare, on the other hand, did not emerge until 3100 BC in Egypt and Mesopotamia. The Chinese general and strategist Sun Tzu, in his The Art of War (6th century BC), became one of the earliest to propose the use of guerrilla warfare.[5] This inspired developments in modern guerrilla warfare.[6]
In the 3rd century BC, Quintus Fabius Maximus Verrucosus, used elements of guerrilla warfare, such as the evasion of battle, the attempt to wear down the enemy, to attack small detachments in an ambush[7] and devised the Fabian strategy, which the Roman Republic used to great effect against Hannibal's army, see also His Excellency: George Washington: the Fabian choice.[8] The Roman general Quintus Sertorius is also noted for his skillful use of guerrilla warfare during his revolt against the Roman Senate. In China, Han dynasty general Peng Yue is often regarded as the inventor of guerrilla warfare due to his use of irregular warfare in the Chu-Han contention to attack Chu convoys and supplies.[9][10]
In the medieval Roman Empire, guerrilla warfare was frequently practiced between the eighth through tenth centuries along the eastern frontier with the Umayyad and then Abbasid caliphates. Tactics involved a heavy emphasis on reconnaissance and intelligence, shadowing the enemy, evacuating threatened population centres, and attacking when the enemy dispersed to raid.[11] In the later tenth century this form of warfare was codified in a military manual known by its later Latin name as De velitatione bellica ('On Skirmishing') so it would not be forgotten in the future.[12]
The Normans often made many forays into Wales, where the Welsh used the mountainous region, which the Normans were unfamiliar with, to spring surprise attacks upon them.[13]
Kerala Varma (Pazhassi Raja) (1753–1805) used guerrilla techniques chiefly centred in mountain forests in the Cotiote War against the British East India Company in India between 1793 and 1806. Arthur Wellesley (in India 1797–1805) had commanded forces assigned to defeat Pazhassi's techniques but failed. It was the longest war waged by East India Company during their military campaigns on the Indian subcontinent. It was one of the bloodiest and hardest wars waged by East India Company in India with Presidency army regiments that suffered losses as high as eighty percent in 10 years of warfare.[16]
Siege of the Fortaleza San Luis by the Dominican rebels by Melanio Guzmán
The Dominican Restoration War was a guerrilla war between 1863 and 1865 in the Dominican Republic between nationalists and Spain, the latter of which had recolonized the country 17 years after its independence. The war resulted in the withdrawal of Spanish forces and the establishment of a second republic in the Dominican Republic.[17]
The Moroccan military leader Abd el-Krim (c.1883 – 1963) and his father[18] unified the Moroccan tribes under their control and took up arms against the Spanish and French occupiers during the Rif War in 1920. For the first time in history, tunnel warfare was used alongside modern guerrilla tactics, which caused considerable damage to both the colonial armies in Morocco.[19]
In the early 20th century Michael Collins and Tom Barry both developed many tactical features of guerrilla warfare during the guerrilla phase of the 1919–1921 Irish War of Independence. Collins developed mainly urban guerrilla warfare tactics in Dublin City (the Irish capital). Operations in which small Irish Republican Army (IRA) units (3 to 6 guerrillas) quickly attacked a target and then disappeared into civilian crowds frustrated the British enemy. The best example of this occurred on Bloody Sunday (21 November 1920), when Collins's assassination unit, known as "The Squad", wiped out a group of British intelligence agents ("the Cairo Gang") early in the morning (14 were killed, six were wounded) – some regular officers were also killed in the purge. That afternoon, the Royal Irish Constabulary force consisting of both regular RIC personnel and the Auxiliary Division took revenge, shooting into a crowd at a football match in Croke Park, killing fourteen civilians and injuring 60 others.[20][21]
In West County Cork, Tom Barry was the commander of the IRA West Cork brigade. Fighting in west Cork was rural, and the IRA fought in much larger units than their fellows in urban areas. These units, called "flying columns",[22] engaged British forces in large battles, usually for between 10 – 30 minutes. The Kilmichael Ambush in November 1920 and the Crossbarry Ambush in March 1921 are the most famous examples of Barry's flying columns causing large casualties to enemy forces.
The Algerian Revolution of 1954 started with a handful of Algerian guerrillas. Primitively armed, the guerrillas fought the French for over eight years. This remains a prototype for modern insurgency and counterinsurgency, terrorism, torture, and asymmetric warfare prevalent throughout the world today.[23] In South Africa, African National Congress (ANC) members studied the Algerian War, prior to the release and apotheosis of Nelson Mandela;[24] in their intifada against Israel, Palestinian fighters have sought to emulate it.[25] Additionally, the tactics of Al-Qaeda closely resemble those of the Algerians.[26]
The Mukti Bahini (Bengali: মুক্তিবাহিনী, translates as "freedom fighters", or liberation army), also known as the Bangladesh Forces, was the guerrilla resistance movement consisting of the Bangladeshi military, paramilitary and civilians during the Bangladesh Liberation War that transformed East Pakistan into Bangladesh in 1971. An earlier name Mukti Fauj was also used.
Theoretical works
The growth of guerrilla warfare was inspired in part by theoretical works on guerrilla warfare, starting with the Manual de Guerra de Guerrillas by Matías Ramón Mella written in the 19th century:
...our troops should...fight while protected by the terrain...using small, mobile guerrilla units to exhaust the enemy...denying them rest so that they only control the terrain under their feet.[27]
More recently, Mao Zedong's On Guerrilla Warfare,[28]Che Guevara's Guerrilla Warfare,[29] and Lenin's Guerrilla warfare,[30] were all written after the successful revolutions carried out by them in China, Cuba and Russia, respectively. Those texts characterized the tactic of guerrilla warfare as, according to Che Guevara's text, being "used by the side which is supported by a majority but which possesses a much smaller number of arms for use in defense against oppression".[31]
Why does the guerrilla fighter fight? We must come to the inevitable conclusion that the guerrilla fighter is a social reformer, that he takes up arms responding to the angry protest of the people against their oppressors, and that he fights in order to change the social system that keeps all his unarmed brothers in ignominy and misery.
In the 1960s, the Marxist revolutionary Che Guevara developed the foco (Spanish: foquismo) theory of revolution in his book Guerrilla Warfare,[33] based on his experiences during the 1959 Cuban Revolution. This theory was later formalized as "focal-ism" by Régis Debray. Its central principle is that vanguardism by cadres of small, fast-moving paramilitary groups can provide a focus for popular discontent against a sitting regime, and thereby lead a general insurrection. Although the original approach was to mobilize and launch attacks from rural areas, many foco ideas were adapted into urban guerrilla warfare movements.
Guerrilla warfare is a type of asymmetric warfare: competition between opponents of unequal strength.[34] It is also a type of irregular warfare: that is, it aims not simply to defeat an invading enemy, but to win popular support and political influence, to the enemy's cost. Accordingly, guerrilla strategy aims to magnify the impact of a small, mobile force on a larger, more cumbersome one.[35] If successful, guerrillas weaken their enemy by attrition, eventually forcing them to withdraw.
Tactically, guerrillas usually avoid confrontation with large units and formations of enemy troops but seek and attack small groups of enemy personnel and resources to gradually deplete the opposing force while minimizing their own losses. The guerrilla prizes mobility, secrecy, and surprise, organizing in small units and taking advantage of terrain that is difficult for larger units to use. For example, Mao Zedong summarized basic guerrilla tactics at the beginning of the Chinese Civil War as:
"The enemy advances, we retreat; the enemy camps, we harass; the enemy tires, we attack; the enemy retreats, we pursue."[36]
At least one author credits the ancient Chinese work The Art of War with inspiring Mao's tactics.[37] In the 20th century, other communist leaders, including North Vietnamese Ho Chi Minh, often used and developed guerrilla warfare tactics, which provided a model for their use elsewhere, leading to the Cuban "foco" theory and the anti-SovietMujahadeen in Afghanistan.[38]
Unconventional methods
Guerrilla groups may use improvised explosive devices and logistical support by the local population. The opposing army may come at last to suspect all civilians as potential guerrilla backers. The guerrillas might get political support from foreign backers and many guerrilla groups are adept at public persuasion through propaganda and use of force.[39] Some guerrilla movements today also rely heavily on children as combatants, scouts, porters, spies, informants, and in other roles.[40] Many governments and states also recruit children within their armed forces.[41][42]
Comparison of guerrilla warfare and terrorism
No commonly accepted definition of "terrorism" has attained clear consensus.[43][44][45] The term "terrorism" is often used as political propaganda by belligerents (most often by governments in power) to denounce opponents whose status as terrorists is disputed.[46][47]
While the primary concern of guerrillas is the enemy's active military units, actual terrorists largely are concerned with non-military agents and target mostly civilians.[48]
Asymmetric warfare is a type of war between belligerents whose relative military power, strategy or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents, terrorist groups or resistance militias who may have the status of unlawful combatants against a standing army.
Seek and destroy is a military strategy which consists of inserting infantry forces into hostile territory and directing them to search and then attack enemy targets before immediately withdrawing. First used as part of counterinsurgency operations during military conflicts in Southeast Asia such as the Malayan Emergency and the Vietnam War, the strategy was developed to take advantage of new technological capabilities available to Western militaries such as the helicopter, which allowed for the adoption of new tactics like the air assault.
People's war or protracted people's war is a Maoist military strategy. First developed by the Chinese communist revolutionary leader Mao Zedong (1893–1976), the basic concept behind people's war is to maintain the support of the population and draw the enemy deep into the countryside where the population will bleed them dry through guerrilla warfare and eventually build up to mobile warfare. It was used by the Chinese communists against the Imperial Japanese Army in World War II, and by the Chinese Soviet Republic in the Chinese Civil War.
A low-intensity conflict (LIC) is a military conflict, usually localised, between two or more state or non-state groups which is below the intensity of conventional war. It involves the state's use of military forces applied selectively and with restraint to enforce compliance with its policies or objectives.
Unconventional warfare (UW) is broadly defined as "military and quasi-military operations other than conventional warfare" and may use covert forces or actions such as subversion, diversion, sabotage, espionage, biowarfare, sanctions, propaganda or guerrilla warfare. This is typically done to avoid escalation into conventional warfare as well as international conventions.
An insurgency is a violent, armed rebellion by small, lightly armed bands who practice guerrilla warfare against a larger authority. The key descriptive feature of insurgency is its asymmetric nature: small irregular forces face a large, well-equipped, regular military force state adversary. Due to this asymmetry, insurgents avoid large-scale direct battles, opting instead to blend in with the civilian population where they gradually expand territorial control and military forces. Insurgency frequently hinges on control of and collaboration with local populations.
Fourth-generation warfare (4GW) is conflict characterized by a blurring of the distinction between war and politics, and of the distinction between combatants and civilians. It is placed as succeeding the third generation in the five-generation model of military theory.
Irregular military is any non-standard military component that is distinct from a country's national armed forces. Being defined by exclusion, there is significant variance in what comes under the term. It can refer to the type of military organization, or to the type of tactics used. An irregular military organization is one which is not part of the regular army organization. Without standard military unit organization, various more general names are often used; such organizations may be called a troop, group, unit, column, band, or force. Irregulars are soldiers or warriors that are members of these organizations, or are members of special military units that employ irregular military tactics. This also applies to irregular infantry and irregular cavalry units.
Modern warfare is warfare that diverges notably from previous military concepts, methods, and technology, emphasizing how combatants must modernize to preserve their battle worthiness. As such, it is an evolving subject, seen differently in different times and places. In its narrowest sense, it is merely a synonym for contemporary warfare.
Counterinsurgency is "the totality of actions aimed at defeating irregular forces". The Oxford English Dictionary defines counterinsurgency as any "military or political action taken against the activities of guerrillas or revolutionaries" and can be considered war by a state against a non-state adversary. Insurgency and counterinsurgency campaigns have been waged since ancient history. However, modern thinking on counterinsurgency was developed during decolonization.
Colonial war is a blanket term relating to the various conflicts that arose as the result of overseas territories being settled by foreign powers creating a colony. The term especially refers to wars fought during the nineteenth century between European armies in Africa and Asia.
A partisan is a member of a domestic irregular military force formed to oppose control of an area by a foreign power or by an army of occupation by some kind of insurgent activity.
During the Vietnam War, the National Liberation Front of South Vietnam (NLF), and the People's Army of Vietnam (PAVN), used a distinctive land warfare strategy to defeat their South Vietnamese Army of the Republic of Vietnam (ARVN) and American opponents. These methods involved closely integrated political and military strategy – what was called dau tranh – literally "to struggle".
Guerrilla Warfare is a military handbook written by Marxist–Leninist revolutionary Che Guevara. Published in 1961 following the Cuban Revolution, it became a reference for thousands of guerrilla fighters in various countries around the world. The book draws upon Guevara's personal experience as a guerrilla soldier during the Cuban Revolution, generalizing for readers who would undertake guerrilla warfare in their own countries.
On Protracted War is a work comprising a series of speeches by Mao Zedong given from May 26, 1938, to June 3, 1938, at the Yenan Association for the Study of the War of Resistance Against Japan. In it, he calls for a protracted people's war, as a means for small revolutionary groups to fight the power of the state.
The main strategy and tactics of guerrilla warfare tend to involve the use of a small attacking, mobile force against a large, unwieldy force. The guerrilla force is largely or entirely organized in small units that are dependent on the support of the local population. Tactically, the guerrilla army makes the repetitive attacks far from the opponent's center of gravity with a view to keeping its own casualties to a minimum and imposing a constant debilitating strain on the enemy. This may provoke the enemy into a brutal, excessively destructive response which will both anger their own supporters and increase support for the guerrillas, ultimately compelling the enemy to withdraw. One of the most famous examples of this was during the Irish War of Independence. Michael Collins, a leader of the Irish Republican Army, often used this tactic to take out squads of British soldiers, mainly in Munster, especially Cork.
The history of guerrilla warfare stretches back to ancient history. While guerrilla tactics can be viewed as a natural continuation of prehistoric warfare, the Chinese general and strategist Sun Tzu, in his The Art of War, was the earliest to propose the use of guerrilla warfare. This directly inspired the development of modern guerrilla warfare. Communist leaders like Mao Zedong and North Vietnamese Ho Chi Minh both implemented guerrilla warfare in the style of Sun Tzu, which served as a model for similar strategies elsewhere, such as the Cuban "foco" theory and the anti-Soviet Mujahadeen in Afghanistan. While the tactics of modern guerrilla warfare originate in the 20th century, irregular warfare, using elements later characteristic of modern guerrilla warfare, has existed throughout the battles of many ancient civilizations.
On Guerrilla Warfare is Mao Zedong's case for the extensive use of an irregular form of warfare in which small groups of combatants use mobile military tactics in the forms of ambushes and raids to combat a larger and less mobile formal army. Mao wrote the book in 1937 to convince Chinese political and military leaders that guerilla style-tactics were necessary for the Chinese to use in the Second Sino-Japanese War.
Guevarism is a theory of communist revolution and a military strategy of guerrilla warfare associated with Marxist–Leninist revolutionary Ernesto "Che" Guevara, a leading figure of the Cuban Revolution who believed in the idea of Marxism–Leninism and embraced its principles.
In military history, the term "generations of warfare" refers to the concept of five "generations" in warfare, with each generation having different tactics, strategies, and technologies. The generations of warfare are sometimes dubbed as "4GW" or "5GW". The term originated in 1989 to describe "the changing face of war" over time, initially only referring to the emergence of the fourth generation, but eventually seeing the addition of a fifth generation.
