History of the British Army

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. From the late 17th century until the mid-20th century, the United Kingdom was the greatest economic and imperial power in the world, and although this dominance was principally achieved through the strength of the Royal Navy (RN), the British Army played a significant role.

As of 2015, there were 92,000 professionals in the regular army (including 2,700 Gurkhas) and 20,480 Volunteer Reserves. Britain has generally maintained only a small regular army during peacetime, expanding this as required in time of war, due to Britain's traditional role as a sea power. Since the suppression of Jacobitism in 1745, the British Army has played little role in British domestic politics (except for the Curragh incident), and, apart from Ireland, has seldom been deployed against internal threats to authority (one notorious exception being the Peterloo Massacre).

The British Army has been involved in many international conflicts, including the Napoleonic Wars, the Crimean War and both World War I and World War II. Historically, it contributed to the expansion and retention of the British Empire.

The British Army has long been at the forefront of new military developments. It was the first in the world to develop and deploy the tank, and what is now the Royal Air Force (RAF) had its origins within the British Army as the Royal Flying Corps (RFC). At the same time the British Army emphasises the continuity and longevity of several of its institutions and military tradition.

Origins

English Army and Royal Scots Army

The English Army was first established as a standing military force in 1660. In 1707 many regiments of the English and Scottish armies were already combined under one operational command and stationed in the Dutch Republic fighting in the War of Spanish Succession. Consequently, although the regiments were now part of the new British military establishment, they remained under the same operational command, and so not only were the regiments of the old armies transferred in situ to the new army so too was the institutional ethos, customs, and traditions, of the old standing armies that had been created shortly after the Stuart Restoration 47 years earlier.

Stuart Asquith argues for roots before 1660: Many authorities quote the Restoration of 1660 as the birth date of our modern British Army. While this may be true as far as continuity of unit identity is concerned, it is untrue in a far more fundamental sense. The evidence of history shows that the creation of an efficient military machine [, The New Model Army,] and its proving on the battlefield, predates the Restoration by 15 years. It was on the fields of Naseby, Dunbar and Dunes that the foundations of the British professional army were laid.

The New Model Army was the first full-time professional army raised within the three kingdoms of England, Ireland and Scotland. It was created in 1645 by the English Long Parliament and it proved supreme in field. At the end of the First Civil War the New Model Army survived attempts by Parliament to disband it. Winston Churchill described its prowess thus: The Story of the Second English Civil War is short and simple. King, Lords and Commons, landlords, merchants, the City and the countryside, bishops and presbyters, the Scottish army, the Welsh people, and the English Fleet, all now turned against the New Model Army. The Army beat the lot!

Having survived Parliament’s attempts to disband it, the New Model Army prospered as an institution during the Interregnum. It was disbanded in 1660 with the restoration of the Stuart monarchy under Charles II.

At his restoration Charles II sought to create a small standing army made up of some former Royalist and New Model Army regiments. On 26 January 1661, Charles II issued the Royal Warrant that created the first regiments of what would become the British Army, although Scotland and England maintained separate military establishments until the Acts of Union 1707. King Charles put into these regiments those cavaliers who had attached themselves to him during his exile on the European continent and had fought for him at the Battle of the Dunes against the Roundheads of the Protectorate and their French allies. For political expediency he also included some elements of the New Model Army. The whole force consisted of two corps of horse and five or six of infantry. It is, however, on this narrow and solid basis that the structure of the English army was gradually erected. The horse consisted of two regiments the Life Guards (formed from exiled cavaliers); and The Blues (or The Oxford Blues), formed by Lord Oxford, out of some of the best New Model Army horse regiments. The foot regiments were Grenadier Guards (initially two regiments Lord Wentworth’s Regiment and John Russell’s Regiment of Guards which amalgamated in 1665), the Coldstream Guards (the New Model Army regiment of General Monck), the Royal Scots (formed from the Scotch guard in France), and the Second Queen’s Royals.

Many of Charles’ subjects were uneasy at his creation of this small army. Pamphleteers wrote tracts voicing the fear of a people who within living memory had experienced the Rule of the Major-Generals 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 Order in Council renewing the Army Act (1955) for a further year.

Creation of the 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 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. Ultimately, the main bodies responsible for the army were:

  • The War Office was responsible for day-to-day administration of the army, and for the cavalry and infantry;
  • The Board of Ordnance was responsible for the supply of weapons and ammunition, and administered the Royal Artillery and Royal Engineers;
  • The Commissariat was responsible for the supply of rations and transport. It occasionally raised its own fighting units, such as “battoemen” (armed watermen and pioneers in North America).

None of these bodies were usually represented in the Cabinet, nor were they responsible for overall strategy, which was in the hands of the Secretary of State for War (an office later merged into the Secretary of State for War and the Colonies).

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, court martials 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 Green Howards) had to be distinguished by their facing colour in official correspondence because for several years, both had colonels named Howard. In time, these became the official names of the regiments. In 1751 a numeral system was adopted, with each regiment gaining a number according to their rank in the order of precedence, so John Mordaunt’s Regiment became the 47th Regiment of Foot.

The later Jacobite risings were centred in the Scottish Highlands. From the late 17th century, the Government had organised Independent Highland Companies in the area, from clans which supported the Hanoverian monarchs or the Whig governments, to maintain order or influence in the Highlands. In 1739 the first full regiment, the 42nd Regiment of Foot, 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.

Strategy and role

From the late 17th century onwards, the British army was to be deployed in three main areas of conflict (the Americas, Continental Europe, and Scotland), one of which (Scotland) was effectively ended at the Battle of Culloden in 1746. The major theatre was often the continent of Europe. Not only did Britain’s monarchs have dynastic ties with Holland or Hanover after the Hanoverian Succession, but Britain’s foreign policy often required intervention to maintain a balance of power in Europe (usually at the expense of the Kingdom of France). Within England and especially Scotland, there were repeated attempts by the exiled House of Stewart and their Jacobite supporters to regain the throne, leading to severe uprisings. These were often related to European conflict, as the Stuarts and Jacobites were aided and encouraged by Britain’s continental enemies for their own ends. After the Battle of Culloden 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 British East India Company), the local forces were administered separately from the British Army, but cooperated with it.

Troops sent to serve overseas could expect to serve there for years, in an unhealthy climate far removed from the comforts of British society. This led to the army being recruited from the elements of society with the least stake in it; the very poorest or worst-behaved. The red-coated soldier, “Thomas Lobster”, was a much-derided figure, as described in the Rudyard Kipling poem Tommy: For it’s Tommy this, an’ Tommy that, an’ “Chuck him out, the brute!” But it’s “Saviour of ‘is country” when the guns begin to shoot; An’ it’s Tommy this, an’ Tommy that, an’ anything you please; An’ Tommy ain’t a bloomin’ fool — you bet that Tommy sees!

Seven Years’ War

The Seven Years’ War, which took place from 1755 to 1763, has sometimes been described as the first true world war, in that conflict took place in almost every continent and on almost all the oceans. Although there were early setbacks, British troops eventually were victorious in every theatre. The war can be said to have started in North America, where it was known as the French and Indian War. The early years saw several British defeats. The British units first despatched to the Continent were untrained in the bush warfare they met. To provide light infantry, several corps such as Rogers’ Rangers were raised from the colonists. (A light infantry regiment, the 80th Regiment of Light-Armed Foot, was raised by Colonel Thomas Gage, but subsequently disbanded). During the war, General James Wolfe amalgamated companies from several regiments into an ad hoc unit, the Louisbourg Grenadiers.

There were also disagreements between high-ranking British officers and the provincial troops recruited from the colonies. It was laid down that even the most senior Provincial officers were subordinate to comparatively junior officers in the British Army. The first concern of the colonists’ representatives was the protection of the settlers from raids by Native American war parties, while the British generals often had different strategic priorities. Partly through the naval superiority gained by the Royal Navy, Britain was eventually able to deploy superior strength in North America, winning the decisive Battle of the Plains of Abraham at Quebec City and conquering New France.

Similarly, in the Indian subcontinent, the French East India Company and the militaries of the most powerful rulers of the Mughal Empire were defeated after the prolonged Third Carnatic War, allowing the steady expansion of British East India Company-controlled territory.

In Europe, although Britain’s allies (chiefly the Royal Prussian Army) carried the main burden of the struggle, British troops eventually played an important role at the decisive Battle of Minden.

First World War (1914–1918)

The British Army during World War I could trace its origins to the increasing demands of imperial expansion together with inefficiencies highlighted during the Crimean War, which led to the Cardwell and Childers Reforms of the late 19th century. These gave the British Army its modern shape, and defined its regimental system. The Esher Report in 1904, recommended radical reform of the British Army, such as the creation of an Army Council, a General Staff and the abolition of the office of Commander in Chief of the Forces and the creation of a Chief of the General Staff. The Haldane Reforms in 1907, created an expeditionary force of seven divisions, it also reorganized the volunteers into a new Territorial Force of fourteen cavalry brigades and fourteen infantry divisions, and changed the old militia into the special reserve to reinforce the expeditionary force.

The British Army was different from the French and German Armies at the beginning of the conflict in that it was made up from volunteers not conscripts. It was also considerably smaller than its French and German counterparts. The British entry into World War I in August 1914 saw the bulk of the changes in the Haldane reforms put to the test. The British Expeditionary Force (BEF) of six divisions was quickly sent to the Continent, while the Territorial Forces fourteen divisions and Reserves were mobilised as planned to provide a second line.

During the war there were three distinct British Armies. The ‘first’ army was the small volunteer force of about 400,000 soldiers (comprising the Regular Army of 247,000 and Territorial Force of 145,000), over half of which were posted overseas to garrison the British Empire. This total included the Regular Army and reservists in the Territorial Force. Together they formed the BEF, for service in France and became known as the Old Contemptibles. The ‘second’ army was Kitchener’s Army, formed from the volunteers in 1914–1915, which was destined to go into action at the Battle of the Somme. The ‘third’ was formed after the introduction of conscription in January 1916 and by the end of 1918 the British Army had reached its peak of strength of four million men and could field over seventy divisions.

The war also saw the introduction of new weapons and equipment. The Maxim machine gun was replaced by the improved and lighter Vickers and Lewis machine guns, the Brodie helmet was supplied for better personnel protection against shrapnel and the Mark I tank was invented to try to end the stalemate of trench warfare.

The vast majority of the British Army fought in France and Belgium on the Western Front but some units were engaged in the Mediterranean, the Middle East, Africa and Mesopotamia, mainly against the Ottoman Empire. One battalion also fought in China during the Siege of Tsingtao.

Second World War (1939–1945)

The British Army in 1939 was a volunteer army that introduced conscription shortly before the declaration of war with Germany. During the early years of the Second World War, the army suffered defeat in almost every theatre it deployed, due to a variety of reasons, mainly because of decisions made before the war and politicians and senior commanders being unclear on what the army’s role was. With mass conscription the expansion of the army was reflected in the creation of more divisions, army corps, armies and army groups. From 1943, the British Army’s fortunes turned and it hardly suffered a strategic defeat.

The pre-war British Army was trained and equipped to garrison and police the British Empire and, as became evident during the war, was woefully unprepared and ill-equipped to conduct a war against multiple enemies on multiple fronts. At the start of the war the army was small in comparison to its enemies’, and remained an all-volunteer force until 1939. By the end of the war the British Army had grown to number over 3.5 million.

The British Army fought around the world, with campaigns in Norway, Belgium and France in 1940 and, after the collapse of both the latter countries, in Africa, the Mediterranean and Middle East and the Far East. After a series of setbacks, retreats and evacuations the British Army and its Allies eventually gained the upper hand. This started with victory over the Italian and German forces in the Tunisia Campaign. Italy was then forced to surrender after the invasion of Sicily and mainland Italy. Then in the last years of the war, the British Army, with its allies, returned to France, driving the German Army back into Germany and in the Far East forced the Japanese back from the Indian border into Burma. Both the Germans and Japanese were defeated by 1945 and surrendered within months of each other.

With the expansion of the British Army to fight a world war, new armies had to be formed, and eventually army groups were created to control even larger formations. In command of these new armies, eight men would be promoted to the rank of field marshal. The army commanders not only had to manage the new armies, but also a new type of soldier in formations that had been created for special service, which included the Special Air Service, Army Commandos and the Parachute Regiment.

End of the Empire and Cold War (1945–1990)

Organisation

The creation of the North Atlantic Treaty Organization (NATO) in 1949 reflected the beginning of the “Cold War” between the ideologically divided “Western Allies” and the Eastern Communist powers, controlled by the Soviet Union; they created their own NATO equivalent in 1955, known as the Warsaw Pact. An integral part of NATO’s defences in the now divided Europe was the British Army of the Rhine (BAOR) in West Germany, the British Army’s new overseas ‘home’ that replaced independent India. The British Army, just as in the aftermath of World War I, had established BAOR in the immediate aftermath of the war which was centred on I Corps (upon its re-establishment in 1951), at its peak reaching about 80,000 troops. At home, there were five regional commands: Eastern, Western, Northern, Scottish, and Southern Command, which all eventually merged to become HQ United Kingdom Land Forces or UKLF in 1972.

The Army was beginning to draw down its forces, beginning the demobilisation of the British Armed Forces shortly after the end of the war. The Territorial units were placed in ‘suspended animation’, being reconstituted upon the reformation of the TA in 1947. On 1 January 1948, National Service, the new name for conscription, formally came into effect. The Army was, however, being reduced in size upon the end of British rule in India and decolonization, including the second battalions of every Line Infantry regiment either amalgamating with the 1st Battalions to maintain the 2nd Battalion’s history and traditions, or simply disband, thus ending the two-battalion policy implemented by Childers in 1881. This proved too severe a decision for the overstretched Army, and a number of regiments reformed their second battalion in the 1950s. The year 1948 also saw the Army receive four Gurkha regiments (eight battalions in total) transferred to them from the Indian Army and were formed into the Brigade of Gurkhas, initially based in Malaya. More reforms of the armed forces took place with the 1957 Defence White Paper, which saw further reductions implemented; the Government realised after the debacle of the Suez Crisis that Britain was no longer a global superpower and decided to withdraw from most of its commitments in the world, limiting the armed forces to concentrating on NATO, with an increased reliance upon nuclear weapons. The White Paper announced that the Army would be reduced in size from about 330,000 to 165,000, with National Service ending by 1963 (it officially ended on 31 December 1960, with the last conscript being discharged in May 1963) with the intention of making the Army into an entirely professional force. This enormous reduction in manpower led to, between 1958 and 1962, eight cavalry and thirty infantry regiments being amalgamated, the latter amalgamations producing fifteen single-battalion regiments. Brigade cap badges superseded the regimental cap badge in 1959.

Many of the regiments created during the 1957 White Paper would have only a brief existence, most being amalgamated into new ‘large’ regiments — The Queen’s, Royal Fusiliers, Royal Anglian, Light Infantry, Royal Irish Rangers, and the Royal Green Jackets—all of whose ‘junior’ battalions were disbanded by the mid-1970s. Two regiments — The Cameronians (Scottish Rifles) and The York and Lancaster Regiment—opted to be disbanded rather than amalgamated. The fourteen administrative brigades (created in 1948) were replaced by six administrative divisions in 1968, with regimental cap badges being re-introduced the following year. The Conservative Government came to power in 1970, one of its pledges included the saving of the Argyll and Sutherland Highlanders after a popular campaign to save it had been provoked by the announcement of its intended demise. The Government also decided to stop the planned amalgamation of The Gloucestershire Regiment with The Royal Hampshire Regiment. Further cavalry and infantry regiments were, however, amalgamated between 1969 and 1971, with six cavalry (into three) and six infantry (also into three) regiments doing so.

For the structure of the Army during this period, see List of British Army regiments (1962). HQ UK Land Forces was formed in 1972, and the previous home commands were effectively downgraded to districts.
