The history of the British Army spans over three and a half centuries since its founding in 1660 and involves numerous European wars, colonial wars and world wars.

and had liked neither the imposition of military rule, or the costs of keeping an army in being when the country was not at war with itself or others. People also remembered the " Eleven Years' Tyranny" of Charles I and feared that a standing army under royal command would allow monarchs in the future to ignore the wishes of Parliament. The English were not fully reconciled to the need for a standing army until the reign of William III when the near perpetual wars with other European states made a modest standing army a necessity to defend England and to maintain her prestige in the world. But public opinion, always anxious of the bad old days, was resolved to allow itself no rest until it had defined the prerogatives of the crown on this delicate point. Parliament finally succeeded in acquiring a control over the army, and under a general bill, commonly called the Mutiny Act, laid down the restrictions which, whilst respecting the rights of the sovereign, were likewise to shield the liberty of the people. It did this by making the standing army conditional on an annually renewed act of Parliament. To this day, annual continuation notices are required for the British Army to remain legal. On paper, this also guarantees representative government, as Parliament must meet at least once a year to ratify the

Creation of British Army

The order of seniority for the most senior line regiments in the British Army is based on the order of seniority in the English army. Scottish and Irish regiments were only allowed to take a rank in the English army from the date of their arrival in England or the date when they were first placed on the English establishment. For example, in 1694 a board of general officers was convened to decide upon rank of English, Irish and Scots regiments serving in the Netherlands, the regiment that became known as the
Scots Greys The Royal Scots Greys was a cavalry regiment of the Army of Scotland that became a regiment of the British Army in 1707 upon the Union of Scotland and England, continuing until 1971 when they amalgamated with the 3rd Carabiniers (Prince of ...
were designated as the 4th dragoons because there were three English regiments raised prior to 1688 when the Scot Greys were first placed on the English establishment. In 1713 when a new board of general officers was convened to decide upon rank of several regiments, the seniority of the Scots Greys was reassessed and based on their entry into England in June 1685. At that time there was only one English regiment of dragoons and so after some delay the Scots Greys obtained the rank of 2nd dragoons in the British Army.

Organisation

By the middle of the century, the army's administration had developed the form which it would retain for more than a hundred years. A number of independent offices and individual officers were responsible for various aspects of Army administration. The most important were the

s. In the field, a commander's staff consisted of an Adjutant General (who handled finance, troop returns and legal matters), and a Quartermaster General (who was responsible for billeting and organising movements). There were separate commanders of the Artillery, and Commissary Officers who handled the supplies. The commander of an Army might also have a Military Secretary, responsible for appointments, courts-martial and official correspondence. Infantry and cavalry units had originally been known by the names of their colonels, such as "Sir John Mordaunt's Regiment of Foot". This could be confusing if colonels succeeded each other rapidly; and two regiments (the Buffs and the

, was formed in the region. Towards the end of the 18th century, the battalion became the major tactical unit of the army. On the continent of Europe, where large field formations were usual, a regiment was a formation of two or more battalions, under a colonel who was a field commander. The British Army, increasingly compelled to disperse units in far-flung colonial outposts, made the battalion the basic unit, under a lieutenant colonel. The function of the regiment became administrative rather than tactical. The colonel of a regiment remained an influential figure but rarely commanded any of its battalions in the field. Many regiments consisted of one battalion only, plus a depot and recruiting parties in Britain or Ireland if the unit was serving overseas. Where more troops were required for a war or garrison duties, second, third and even subsequent battalions of a regiment were raised, but it was rare for more than one battalion of a regiment to serve in the same brigade or division.

From the late 17th century onwards, the British army was to be deployed in three main areas of conflict (the

in 1746, these rebellions were crushed. Finally, as the British empire expanded, the army was increasingly involved in service in the West Indies, North America and India. Troops were often recruited locally, to lessen the burden on the Army. Sometimes these were part of the British army, for example the 60th (Royal American) Regiment of Foot. On other occasions (as in the case of troops raised by the

, which learned they had to help defend themselves. The most radical change, and one that required Gladstone's political muscle, was to abolish the system of officers obtaining commissions and promotions by purchase, rather than by merit. The system meant that the rich landholding families controlled all the middle and senior ranks in the army. Promotion depended on the family's wealth, not the officer's talents, and the middle class was shut out almost completely. British officers were expected to be gentlemen and sportsmen; there was no problem if they were entirely wanting in military knowledge or leadership skills. From the Tory perspective it was essential to keep the officer corps the domain of gentlemen, and not a trade for professional experts. They warned the latter might menace the oligarchy and threaten a military coup; they preferred an inefficient army to an authoritarian state. The

The bill, which would have compensated current owners for their cash investments, passed the Commons in 1871 but was blocked by the House of Lords. Gladstone then moved to drop the system without any reimbursements, forcing the Lords to backtrack and approve the original bill. Liberals rallied to Gladstone's anti-elitism, pointing to the case of Lord Cardigan (1797–1868), who spent £40,000 for his commission and proved utterly incompetent in the Crimean war, where he ordered the disastrous "Charge of the Light Brigade" in 1854. Cardwell was not powerful enough to install a general staff system; that had to await the 20th century. He did rearrange the war department. He made the office of Secretary of State for War superior to the Army's commander in Chief; the commander was His Royal Highness the

The militia was reformed as well and integrated into the Army. The term of enlistment was reduced to 6 years, so there was more turnover and a larger pool of trained reservists. The territorial system of recruiting for regiments was standardised and adjusted to the current population. Cardwell reduced the Army budget yet increased its strength of the army by 25 battalions, 156 field guns, and abundant stores, while the reserves available for foreign service had been raised tenfold from 3,500 to 36,000 men.

abandoned their horses. After the Munich Crisis in 1938, a serious effort was undertaken to expand the Army, including the doubling in size of the Territorial Army, helped by the reintroduction of conscription in April 1939. By mid-1939 the Army consisted of 230,000 Regulars and 453,000 Territorials and Reservists. Most Territorial formations were understrength and badly equipped. Even this army was dwarfed, yet again, by its continental counterparts. Just before the war broke out, a new British Expeditionary Force was formed. By the end of the year, over 1 million had been conscripted into the Army. Conscription was administered on a better planned basis than in the First World War. People in certain

British de-colonialisation and the British Army

The latter part of the 1940s saw the British start to begin to withdraw from the Empire, the Army playing a prominent role in its dismantlement. The first colony the British withdrew from was India, the largest British possession as measured by population, though not the largest by geographical area. In 1947 the British government announced India would become independent on 15 August, after being separated into two countries, one mostly Muslim (

). The British Army subsequently did not play a major role in the Indo-Pakistani War of 1947–1948, First Indo-Pakistani War between these two countries. The last British Army unit to leave active service in the Indian subcontinent was the 1st Battalion, The Somerset Light Infantry (Prince Albert's) on 28 February 1948. In the 1948 Palestine war, there was a 1947–1948 civil war in Mandatory Palestine, surge in attacks against the Mandatory Palestine, British mandate and occupation by Zionist organisations such as Irgun and the Stern Gang after the British attempted to limit Aliyah, Jewish immigration into Palestine. British military and other forces eventually withdrew in 1948 and the State of Israel was established on 14 May. Elsewhere, within British territories, Communist guerrillas launched an uprising in Malaya, starting the Malayan Emergency.Mallinson, p. 402 In the early 1950s, trouble began in British Cyprus, Cyprus, and in Kenya Colony, Kenya—the Mau Mau uprising.Mallinson, p. 401 In the Cyprus Emergency, a Greek nationalism, Greek nationalist organisation known as EOKA sought Enosis, unity with Greece, the situation being stabilised just before Cyprus was given independence in 1960.


Korea

The British Army also participated in the United Nations Command's 1st Commonwealth Division during the Korean War (1950–53), fighting in battles such as Battle of the Imjin River, Imjin River which included Gloster Hill. In late 1950, many people in Pyongyang fled the Chinese People's Volunteer Army advanced on the city: the British Army provided supervision and protection for the refugees as they fled from the Chinese military advance on Pyongyang.


More British de-colonialisation

Elsewhere, the Army withdrew from the Suez Canal Zone in Egypt in 1955. The following year, along with France and Israel, the British invaded Egypt in a conflict known as the Suez War, after the Egyptian leader, President Gamal Abdel Nasser, Nasser nationalised the Suez Canal which privately owned businesses in Britain and France owned shares in. The British Army contributed forces to the amphibious assault on Suez and British paratroopers took part in the airborne assault. This brief war was a military success. However, international pressure, especially from the US government, soon forced the British government to withdraw all their military forces soon afterwards. British military forces were replaced by United Nations Emergency Force peacekeeping troops. In the 1960s two conflicts featured heavily with the Army, the Aden Emergency and the Indonesia–Malaysia confrontation in Borneo.


Operations within the United Kingdom


Northern Ireland

In 1969 a 1969 Northern Ireland Riots, surge of sectarian violence and attacks in Northern Ireland against Irish Catholics by Ulster Protestants, Ulster loyalism, Ulster loyalists, and the Royal Ulster Constabulary in which seven people were killed, hundreds more wounded and thousands of Catholic families were driven from their homes led to British troops being sent into Northern Ireland to try to stop the violence. This became Operation Banner. Among those killed in the attacks by the RUC was Trooper Hugh McCabe, the first British soldier to die in The Troubles. The troops were initially welcomed by the Catholic community as they believed the troops would protect them; however, this developed into opposition as the troops began to support the RUC, and the Provisional Irish Republican Army (PIRA), a militant break-away from the original Irish Republican Army (1922–1969), Irish Republican Army which had been quiet since the 1962 cessation of the Border Campaign (IRA), Border Campaign, began to target British troops. The British Army's operations in the early phase of its deployment had it placed in a policing role, for which, in many cases, it was ill-suited. This involved seeking to prevent confrontations between the Catholics and Protestants, as well as putting down riots and stopping Irish Republicanism, Republican and Ulster loyalism, Loyalist paramilitary groups from committing terrorist attacks. However, as the Provisional Irish Republican Army campaign grew in ferocity in the early 1970s, the Army was increasingly caught in a situation where its actions were directed against the IRA and the Catholic Irish nationalist community which harboured it. In the early period of the conflict, British troops mounted several major field operations. The first of these was the Falls Curfew of 1971, when over 3,000 troops imposed a 3-day curfew on the Falls Road (Belfast), Falls Road area of Belfast and fought a sustained gun battle with local IRA men. In Operation Demetrius in June 1971, 300 paramilitary suspects were internment, interned without trial, an action which provoked a major upsurge in violence. The largest single British operation of the period was Operation Motorman in 1972, when about 21,000 troops were used to restore state control over areas of Belfast and Derry, which were then controlled by republican paramilitaries. The British Army's reputation suffered further from an incident in Derry on 30 January 1972, Bloody Sunday (1972), Bloody Sunday in which 13 Catholic civilians were murdered by The Parachute Regiment. The biggest single loss of life for British troops in the conflict came at Narrow Water, where eighteen British soldiers were killed in a PIRA bomb attack on 27 August 1979, on the same day Louis Mountbatten, 1st Earl Mountbatten of Burma, Lord Mountbatten of Burma was Assassination of Louis Mountbatten, 1st Earl Mountbatten of Burma, assassinated by the PIRA in a separate attack. In all almost 500 British troops died in Northern Ireland between 1969 and 1997. By the late 1970s, the British Army was replaced to some degree as "frontline" security service, in preference for the local Royal Ulster Constabulary and the Ulster Defence Regiment (raised 1970) as part of the Ulsterisation policy. By the 1980s and early 1990s, British Army casualties in the conflict had dropped. Moreover, British Special Forces had some successes against the PIRA – see Operation Flavius and the Loughgall Ambush. Nevertheless, the conflict tied up over 12,000 British troops on a continuous basis until the late 1990s and was ended with the Good Friday Agreement which detailed a path to a political solution to the conflict. Operation Banner came to an end in 2007 making it the longest continuous operation in the British Army's history, lasting over thirty-eight years. Troop numbers were reduced to 5,000.

Falklands War

One remaining garrison provided by the Royal Marines was the Falkland Islands in the South Atlantic, 6,000 to (11,000 to 15,000 km) from Britain. The 1982 invasion of the Falkland Islands, Argentinians invaded the Falklands in April 1982. The British quickly responded and the Army had an active involvement in the campaign to liberate the Falklands upon the landings at San Carlos, Falkland Islands, San Carlos, taking part in a series of battles that led to them reaching the outskirts of the capital, Stanley, Falkland Islands, Stanley. The Falklands War ended with the formal surrender of the Armed Forces of the Argentine Republic on 14 June.


1990–present


Organisation

The Dissolution of the Soviet Union, collapse of the Soviet Union, ending the Cold War, saw a new defence white paper, Options for Change produced.Defence (Options for Change)
Hansard, 25 July 1990
This saw inevitable reductions in the British armed forces. The Army experienced a substantial cut in its manpower (reduced to about 120,000), which included yet more regimental amalgamations, including two of the large regiments of the 1960s—the Queen's Regiment and Royal Irish Rangers—and the third battalions of the remaining large regiments being cut. The British Army in Germany was also affected, with the British Army of the Rhine replaced by British Forces Germany and personnel numbers being reduced from about 55,000 to 25,000; the replacement of German-based I Corps by the British-led Allied Rapid Reaction Corps also took place. Nine of the Army's administrative corps were amalgamated to form the Royal Logistic Corps and the Adjutant General's Corps. One major development was the disbandment of the Women's Royal Army Corps (though the largest elements were absorbed by the AGC) and their integration into services that had previously been restricted to men; however, women were still prohibited from joining armoured and infantry units. The four Gurkha regiments were amalgamated to form the three-battalion Royal Gurkha Rifles, reduced to two in 1996 just before the handover of Hong Kong to the People's Republic of China in 1997. The Labour Party (UK), Labour Party became the country's new government and after their victory in the 1997 United Kingdom general election, 1997 general election a new defence white paper was prepared, known as the Strategic Defence Review (1998), Strategic Defence Review (1998). Some of the Army's reforms included the creation of two deployable divisions -- 1st (UK) Armoured Division and British 3rd Infantry Division, 3rd Mechanised Division, with the 1st Division being based in Germany—and three 'regenerative' divisions -- British 2nd Infantry Division, 2nd, British 4th Infantry Division, 4th, and British 5th Infantry Division, 5th Divisions. The British 16 Air Assault Brigade, 16 Air Assault Brigade was formed from British 24 Airmobile Brigade, 24 Airmobile Brigade and elements of British 5 Airborne Brigade, 5 Airborne Brigade to provide the Army with increased mobility, and would include the Westland WAH-64 Apache attack helicopter. Other attempts to make the Army more mobile was the creation of the Joint Rapid Reaction Force (United Kingdom), Joint Rapid Reaction Force, intended to provide a corps-sized force capable of reacting quickly to situations similar to Bosnia. The Army Air Corps's helicopters also helped form the multi-service Joint Helicopter Command. Another defence review was published in 2004, known as Delivering Security in a Changing World. The defence white paper stated that the Army's manpower would be reduced by 1,000, with four infantry battalions being cut and the manpower being redistributed elsewhere. One of the most radical aspects of the reforms was the announcement that most single-battalion regiments would amalgamate into large regiments, with most of the battalions retaining their previous regimental titles in their battalion names. The TA would also be further integrated into the Army, with battalions being numbered into the regiment's structure. These are reminiscent, in some respects, to the Cardwell-Childers reforms and the 1960s reforms. The elite units of the Army are also playing an increasingly prominent role in the Army's operations and the SAS was allocated further funds in the 2004 defence paper, conveying the SAS's increasing importance in the War on Terror. Another élite unit became operational in 2005, the Special Reconnaissance Regiment. The 1st Battalion of the Parachute Regiment became the core of a tri-service Special Forces Support Group formed in 2006 to support the SAS and the Navy's Special Boat Service, SBS, being described as the Army's equivalent to the U.S. Army Rangers.


Operations

The end of the Cold War did not provide the British Army with any respite, and the political vacuum left by the Soviet Union has seen a surge of instability in the world. Saddam Hussein's Ba'athist Iraq, Iraq Iraqi invasion of Kuwait, invaded Kuwait, one of its neighbours, in 1990, provoking condemnation from the United Nations, primarily led by the United States. The Gulf War and the British contribution, known as Operation Granby, was large, with the Army providing about 28,000 troops and 13,000 vehicles, mostly centred on 1 (UK) Armoured Division. After air operations ended, the land campaign against Iraq began on 24 February. 1st Armoured Division took part in the left-hook attack that helped destroy many Iraqi units. The ground campaign had lasted just 100-hours, Liberation of Kuwait campaign, Kuwait being officially liberated on 27 February. The British Army has also played an increasingly prominent role in peacekeeping operations, gaining much respect for its comparative expertise in the area. In 1992, during the Yugoslav Wars, wars in the Balkans provoked by the gradual Breakup of Yugoslavia, disintegration of Yugoslavia, UN forces intervened in the Croatian War of Independence and later the Bosnian War. British forces contributed as part of UNPROFOR (United Nations Protection Force). The force was a peacekeeping one, but with no peace to keep, it proved ineffective and was replaced by NATO's Implementation Force, though this was in turn replaced the following year by the Stabilisation Force in Bosnia and Herzegovina. As of 2005, Britain's contribution numbers about 3,000 troops. In 1999 the UK took a lead role in the NATO war against Slobodan Milošević's Serbia and Montenegro, Federal Republic of Yugoslavia in the Kosovo War. After the air war ended, the Parachute Regiment and Royal Gurkha Rifles provided the spearhead for ground forces entering Kosovo. In 2000, British forces, as part of Operation Palliser, intervened in the Sierra Leone Civil War, with the intention of evacuating British, Commonwealth and EU citizens. The SAS also played a prominent role when they, along with the Paras, launched the successful Operation Barras to rescue 6 soldiers of the Royal Irish Regiment (1992), Royal Irish Regiment being held by the rebels. The British force remained and provided the catalyst for the stabilisation of the country. The early 21st century saw the world descend into a new war after the September 11 attacks, 9/11 terrorist attacks on the World Trade Center (1973–2001), World Trade Center in New York City by Al-Qaeda, Al Qaida: the War on Terrorism. A United States invasion of Afghanistan, US-led invasion of Taliban-ruled Afghanistan followed, with the British contribution under Operation Veritas, Operations Veritas led by the RN and RAF; the most important Army element being the SAS. The British Armed Forces continued contributing to NATO's International Security Assistance Force through Operation Herrick between 2002 and 2014 and then to its successor the Resolute Support Mission under Operation Toral until 2021. The British later took part in the 2003 Iraq War, invasion of Iraq in 2003, Britain's contribution being known as Operation Telic, The Army played a more significant role in the Iraq War than the War in Afghanistan (2001–2021), War in Afghanistan, deploying a substantial force, centred on 1 (UK) Armoured Division with, again, around 28,000 troops. The war began in March and the British fought in the southern area of Iraq, eventually capturing the second largest city, Basra, in April. The Army remained in Iraq upon the end of the war and subsequently led the Multi-National Division (South-East) (Iraq), Multi-National Division (South East), with the Army presence in Iraq numbering about 5,000 soldiers.Mallinson, p. 463
