Who was B.H. Liddell Hart?


Sir Basil Henry Liddell Hart (31 October 1895 to 29 January 1970), commonly known throughout most of his career as Captain B.H. Liddell Hart, was a British soldier, military historian and military theorist.

He wrote a series of military histories that proved influential among strategists. He argued that frontal assault was a strategy that was bound to fail at great cost in lives, as happened in the First World War. He instead recommended the “indirect approach” and reliance on fast-moving armoured formations.

His pre-war publications are known to have influenced German wartime strategy, though he was accused of prompting captured generals to exaggerate his part in the development of blitzkrieg tactics. He also helped promote the Rommel myth and the “clean Wehrmacht” argument for political purposes, when the Cold War necessitated the recruitment of a new West German army.


Liddell Hart was born in Paris, the son of a Methodist minister. His mother’s side of the family, the Liddells, came from Liddesdale, on the Scottish side of the border with England, and were associated with the London and South Western Railway. The Harts were farmers from Gloucestershire and Herefordshire. As a child Liddell Hart was fascinated by aviation. He received his formal academic education at Willington School in Putney, St Paul’s School in London and at Corpus Christi College, Cambridge (where he was a student of Geoffrey Butler).

On the outbreak of World War I in August 1914, Liddell Hart volunteered for the British Army, where he became an officer in the King’s Own Yorkshire Light Infantry and served with the regiment on the Western Front. Liddell Hart’s front line experience was relatively brief, confined to two short spells in the autumn and winter of 1915, being sent home from the front after suffering concussive injuries from a shell burst. He was promoted to the rank of captain. He returned to the front for a third time in 1916, in time to participate in the Battle of the Somme. He was hit three times without serious injury before being badly gassed and sent out of the line on 19 July 1916. His battalion was nearly wiped out on the first day of the offensive on 01 July, a part of the 60,000 casualties suffered in the heaviest single day’s loss in British history. The experiences he suffered on the Western Front profoundly affected him for the rest of his life. Transferred to be adjutant of Volunteer units in Stroud and Cambridge which trained new recruits, he wrote several booklets on infantry drill and training, which came to the attention of General Sir Ivor Maxse, commander of the 18th (Eastern) Division. After the war, he transferred to the Royal Army Educational Corps, where he prepared a new edition of the Infantry Training Manual. In it, Liddell Hart strove to instil the lessons of 1918, and carried on a correspondence with Maxse, a commanding officer during the battles of Hamel and Amiens.

In April 1918 Liddell Hart married Jessie Stone, the daughter of J.J. Stone, who had been his assistant adjutant at Stroud, and their son Adrian was born in 1922.

Journalist and Military Historian

Liddell Hart was placed on half-pay from 1924. He later retired from the Army in 1927. Two mild heart attacks in 1921 and 1922, probably the long-term effects of his gassing, precluded his further advancement in the small post-war army. He spent the rest of his career as a theorist and writer. In 1924, he became a lawn tennis correspondent and assistant military correspondent for The Morning Post covering Wimbledon and in 1926, publishing a collection of his tennis writings as The Lawn Tennis Masters Unveiled. He worked as the military correspondent of The Daily Telegraph from 1925 to 1935 and of The Times from 1935 to 1939.

In the mid-to-late 1920s Liddell Hart wrote a series of histories of major military figures through which he advanced his ideas that the frontal assault was a strategy bound to fail at great cost in lives. He argued that the tremendous losses Britain suffered in the Great War were caused by its commanding officers not appreciating that fact of history. He believed the British decision in 1914 of directly intervening on the Continent with a great army was a mistake. He claimed that historically, “the British way in warfare” was to leave Continental land battles to her allies, intervening only through naval power, with the army fighting the enemy away from its principal front in a “limited liability” commitment.

In his early writings on mechanised warfare, Liddell Hart had proposed that infantry be carried along with the fast-moving armoured formations. He described them as “tank marines” like the soldiers the Royal Navy carried with their ships. He proposed they be carried along in their own tracked vehicles and dismount to help take better-defended positions that otherwise would hold up the armoured units. That contrasted with J.F.C. Fuller’s ideas of a tank army, which put heavy emphasis on massed armoured formations. Liddell Hart foresaw the need for a combined arms force with mobile infantry and artillery, which was similar but not identical to the make-up of the panzer divisions that Heinz Guderian developed in Germany.

According to Liddell Hart’s memoirs, in a series of articles for The Times from November 1935 to November 1936, he had argued that Britain’s role in the next European war should be entrusted to the air force. He theorised that Britain’s air force could defeat her enemies while avoiding the high casualties and the limited influence that would come from Britain placing a large conscript army on the Continent. The ideas influenced Neville Chamberlain, then Chancellor of the Exchequer, who argued in discussions of the Defence Policy and Requirements Committee for a strong air force, rather than a large army that would fight in the Continent.

Becoming prime minister in 1937, Chamberlain placed Liddell Hart in a position of influence behind British grand strategy in the late 1930s. In May, Liddell Hart prepared schemes for the reorganisation of the British Army for the defence of the British Empire and delivered them to Sir Thomas Inskip, Minister for the Co-ordination of Defence. In June, Liddell Hart gained an introduction to the Secretary of State for War, Leslie Hore-Belisha. Through July 1938 the two had an unofficial, close advisory relationship. Liddell Hart provided Hore-Belisha with ideas, which he would argue for in Cabinet or committees. On 20 October 1937, Chamberlain wrote to Hore-Belisha, “I have been reading in Europe in Arms by Liddell Hart. If you have not already done so you might find it interesting to glance at this, especially the chapter on the ‘Role of the British Army'”. Hore-Belisha wrote in reply: “I immediately read the ‘Role of the British Army’ in Liddell Hart’s book. I am impressed by his general theories”.

With the German invasion of Poland in September 1939, the War Cabinet reversed the Chamberlain policy advanced by Liddell Hart. With Europe on the brink of war and Germany threatening an invasion of Poland, the cabinet chose instead to advocate a British and Imperial army of 55 divisions to intervene on the Continent by coming to the aid of Poland, Norway and France.


After the war, Liddell Hart was responsible for extensive interviews and debriefs for several high-ranking German generals, who were held by the Allies as prisoners-of-war. Liddell Hart provided commentary on their outlook. The work was published as The Other Side of the Hill (UK edition, 1948) and The German Generals Talk (condensed US edition, 1948).

A few years later, Liddell Hart had the opportunity to review the notes that Erwin Rommel had kept during the war. Rommel had kept the notes with the intention of writing of his experiences after the war; the Rommel family had previously published the notes in German as War without Hate in 1950. Some of the notes had been destroyed by Rommel, and the rest, including Rommel’s letters to his wife, had been confiscated by the American authorities. With Liddell Hart’s help, they were later returned to Rommel’s widow. Liddell Hart then edited and condensed the book and helped integrate the new material. The writings, along with notes and commentary by former General Fritz Bayerlein and Liddell Hart, were published in 1953 as The Rommel Papers (See below for Liddell Hart’s role in the Rommel myth).

In 1954, Liddell Hart published his most influential work, Strategy. It was followed by a second expanded edition in 1967. The book was largely devoted to a historical study of the indirect approach and in what ways various battles and campaigns could be analysed using that concept. Still relevant at the turn of the century, it was a factor in the development of the British manoeuvre warfare doctrine.

The Queen made Liddell Hart a Knight Bachelor in the New Year Honours of 1966. As of 2009, Liddell Hart’s personal papers and library form the central collection in the Liddell Hart Centre for Military Archives at King’s College London.

Liddell Hart died on 29 January 1970 at the age of 74 at his home in Marlow, Buckinghamshire.

Key Ideas and Observations

[N]ot of one period but of its whole course, points to the fact that, in all decisive campaigns, the dislocation of the enemy’s psychological and physical balance has been the vital prelude to his overthrow. B.H. Liddell Hart

Liddell Hart was an advocate of the notion that it is easier to succeed in war by an indirect approach. To attack where the opponent expects, as Liddell Hart explained, makes the task of winning harder: “To move along the line of natural expectation consolidates the opponent’s balance and thus increases his resisting power”. That is in contrast to an indirect approach, in which physical or psychological surprise is a component: “The indirectness is usually physical and always psychological. In strategy, the longest way round is often the shortest way home”. Liddell Hart would illustrate the notion with historical examples. For example, Liddell Hart considered the Battle of Leuctra, won by Epaminondas, an example of an indirect approach. Rather than weighting his army on the right wing, as was standard at the time, Epaminondas weighted his left wing, held back his right wing and routed the Spartan army. A more modern example would be the landings of the Allies at Normandy on 06 June 1944, as the Germans were expecting a landing in the vicinity of Pas-de-Calais. By contrast, an example of a direct attack, in Liddell Hart’s eyes, was the attack by Union forces at the Battle of Fredericksburg in 1862.

Even more impressive in Liddell Hart’s eyes was the further campaign by Epaminondas, his invasion of the Peloponnese, in which in winter and in separate columns, he invaded Spartan controlled territory. He was unable to draw the Spartans into combat and so settled on freeing helots. He then built two city states as a break against Spartan power and so the campaign was successful. By breaking the Spartan economic base, he won a campaign without ever fighting a battle.

When analysing the campaigns of Napoleon, Liddell Hart noted that his approaches were less subtle and more brute force as his forces became larger and that when his forces were lesser, he was more apt to be creative in his battles. Constant victory seemed to have dulled his skills as a soldier.

According to Reid, Liddell Hart’s indirect approach has seven key themes:

  1. The dislocation of the enemy’s balance should be the prelude to defeat, not to utter destruction.
  2. Negotiate an end to unprofitable wars.
  3. The methods of the indirect approach are better suited to democracy.
  4. Military power relies on economic endurance. Defeating an enemy by beating him economically incurs no risk.
  5. Implicitly, war is an activity between states.
  6. Liddell Hart’s notion of “rational pacifism”.
  7. Victory often emerges as the result of an enemy defeating itself.


During the 1960s Liddell Hart’s reputation reached extraordinary heights. When he visited Israel in 1960 his trip stimulated more public interest than that of any other foreign visitor except Marilyn Monroe. Brian Holden Reid.

Liddell Hart’s reputation as a military thinker stood very high at his death in 1970. Post-mortem assessments, however, have been more ambivalent. Christopher Bassford.

At the height of his popularity, John F. Kennedy called Liddell Hart “the Captain who teaches Generals” and was using his writings to attack the Eisenhower administration, which he said was too dependent on nuclear arms. Liddell Hart influence extended to armies outside the UK and the US as well. Baumgarten stated of Liddell Hart’s influence in the Australian Army: “The indirect approach was also one of the key influences on the development of manoeuvre theory, a dominant element in Army thinking throughout the 1990s”. Retired Pakistani General Shaafat Shah called Liddell Hart’s book Strategy: the Indirect Approach “A seminal work of military history and theory”. In the book Science, Strategy and War, Frans Osinga mentioned while the Dutchman spoke of John Boyd, “In his recently published study of modern strategic theory, Colin Gray ranked Boyd among the outstanding general theorists of the strategy of the 20th century, along with the likes of Bernard Brodie, Edward Luttwak, Basil Liddell Hart and John Wylie”. His biographer, Alex Danchev, noted that Liddell Hart’s books were still being translated all around the world, some of them 70 years after they had been written.


Influence on Panzerwaffe

Following the Second World War Liddell Hart pointed out that the German Wehrmacht adopted theories developed from those of J.F.C. Fuller and from his own, and that it used them against the Allies in Blitzkrieg warfare.[49] Some scholars, such as the political scientist John Mearsheimer, have questioned the extent of the influence which the British officers, and in particular Liddell Hart, had in the development of the method of war practised by the Panzerwaffe in 1939-1941. During the post-war debriefs of the former Wehrmacht generals, Liddell Hart attempted to tease out his influence on their war practices. Following these interviews, many of the generals said that Liddell Hart had been an influence on their strategies, something that had not been claimed previously nor has any contemporary, pre-war, documentation been found to support their assertions. Liddell Hart thus put “words in the mouths of German Generals” with the aim, according to Mearsheimer, to “resurrect a lost reputation”.

Shimon Naveh, the founder and former head of the Israel Defense Forces’ Operational Theory Research Institute, stated that after World War II Liddell Hart “created” the idea of Blitzkrieg as a military doctrine: “It was the opposite of a doctrine. Blitzkrieg consisted of an avalanche of actions that were sorted out less by design and more by success.” Naveh stated that,

by manipulation and contrivance, Liddell Hart distorted the actual circumstances of the Blitzkrieg formation and obscured its origins. Through his indoctrinated idealization of an ostentatious concept, he reinforced the myth of Blitzkrieg. By imposing, retrospectively, his own perceptions of mobile warfare upon the shallow concept of Blitzkrieg, he created a theoretical imbroglio that has taken 40 years to unravel.

Naveh stated that in his letters to German generals Erich von Manstein and Guderian, as well as to relatives and associates of Rommel, Liddell Hart “imposed his own fabricated version of Blitzkrieg on the latter and compelled him to proclaim it as original formula”.

Naveh pointed out that the edition of Guderian’s memoirs published in Germany differed from the one published in the United Kingdom. Guderian neglected to mention the influence of the English theorists such as Fuller and Liddell Hart in the German-language versions. One example of the influence of these men on Guderian was the report on the Battle of Cambrai published by Fuller in 1920, who at the time served as a staff officer at the Royal Tank Corps. Liddell Hart alleged that his findings and theories on armoured warfare were read and later taken in by Guderian, which thus helped to formulate the basis of operations that would become known as Blitzkrieg warfare. These tactics involved deep penetration of the armoured formations supported behind enemy lines by bomb-carrying aircraft. Dive bombers were the principal agents of delivery of high explosives in support of the forward units.

Though the German version of the Guderian memoirs mentions Liddell Hart, it did not ascribe to him his role in developing the theories behind armoured warfare. An explanation for the difference between the two translations can be found in the correspondence between the two men. In one letter to Guderian, Liddell Hart reminded the German general that he should provide him the credit he was due, offering “You might care to insert a remark that I emphasise the use of armoured forces for long-range operations against the opposing Army’s communications, and also the proposed type of armoured division combining Panzer and Panzer-infantry units – and that these points particularly impressed you.”

Richard M. Swain comments that while some arguments against Liddell Hart’s thinking are deserved, Liddell Hart the man himself was not a knave and Mearsheimer’s attempt of character assassination is unwarranted. Jay Luvaas comments that Liddell Hart and Fuller did actually anticipate the role of the armoured forces in a blitzkrieg. Luvaas opines that Liddell Hart did overestimate (in a sincere way) his influence on German generals, but the fact that many military leaders in Germany and other countries (including generals like Yigal Allon and Andre Beaufre) knew about his theories and considered his opinions as worth thinking about is true. According to Luvaas, von Mellenthin recounted that Rommel mentioned Liddell Hart many times and had a good opinion about him – although, in Luvaas’s opinion, this would not make him a pupil. Luvass also sees Liddell Hart as a scholar who needed public recognition and influence, but also a naturally generous person whose efforts in building a connection to other people should not be assigned motives without evidence. Joseph Forbes dismisses the claim that Liddell Hart, Guderian and Rommel’s friends and relatives were in a conspiracy to misrepresent Liddell Hart’s influence as baseless insinuations, considering that: Liddell Hart’s chapter on Guderian quotes Guderian as having faith in the theories of Hobart and not of Liddell Hart; the fact Desmond Young once recommended Liddell Hart to Manfred Rommel as a person who might help to publish his father’s memoirs should not be used as proof that there was a conspiracy to give undue recognition to Liddell Hart; the whole book The German Generals talk contains one statement about Liddell Hart’s influence (According to Forbes, Mearsheimer relies less on the actual text than on Frank Mahin’s review to make the claim that Hart fills the book with fabricated comments by Germans to exaggerate his role).

Role in Rommel Myth

Liddell Hart was instrumental in the creation of the “Rommel myth”, a view that the German field marshal Erwin Rommel was an apolitical, brilliant commander and a victim of the Third Reich due to his (now disputed)[dubious – discuss] participation in the 20 July plot against Adolf Hitler. The myth was created with Rommel’s participation as a component of Nazi propaganda to praise the Wehrmacht and instil optimism in the German public. Starting in 1941, it was picked up and disseminated in the West by the British press as they sought to explain its continued inability to defeat the Axis forces in North Africa. Following the war, the Western Allies, and particularly the British, depicted Rommel as the “good German” and “our friend Rommel”. His reputation for conducting a clean war was used in the interest of the West German rearmament and reconciliation between the former enemies – Britain and the United States on one side and the new Federal Republic on the other.

After the outbreak of the Korean War in 1950, it became clear to the Americans and the British that a German army would have to be revived to help face off against the Soviet Union. Many former German officers were convinced, however, that no future German army would be possible without the rehabilitation of the Wehrmacht. Thus, in the atmosphere of the Cold War, Rommel’s former enemies, especially the British, played a key role in the manufacture and propagation of the myth. The German rearmament was highly dependent on the image boosting that the Wehrmacht needed. Liddell Hart, an early proponent of these two interconnected initiatives, provided the first widely available source on Rommel in his 1948 book on Hitler’s generals. He devoted a chapter to Rommel, portraying him as an outsider to the Nazi regime. Additions to the chapter published in 1951 concluded with laudatory comments about Rommel’s “gifts and performance” that “qualified him for a place in the role of the ‘Great Captains’ of history”.

1953 saw the publication of Rommel’s writings of the war period as The Rommel Papers, edited by Liddell Hart, the former Wehrmacht officer Fritz Bayerlein, and Rommel’s widow and son, with an introduction by Liddell Hart. The historian Mark Connelly argues that The Rommel Papers was one of the two foundational works that lead to a “Rommel renaissance”, the other being Desmond Young’s biography Rommel: The Desert Fox. The book contributed to the perception of Rommel as a brilliant commander; in an introduction, Liddell Hart drew comparisons between Rommel and Lawrence of Arabia, “two masters of desert warfare”, according to Liddell Hart. Liddell Hart’s work on the book was also self-serving: he had coaxed Rommel’s widow into adding material that suggested that Rommel was influenced by Liddell Hart’s theories on mechanised warfare, making Rommel his “pupil” and giving Liddell Hart credit for Rommel’s dramatic successes in 1940 (The controversy was described by the political scientist John Mearsheimer in his work The Weight of History. A review of Mearsheimer’s work, published by the Strategic Studies Institute, points out that Mearsheimer “correctly takes ‘The Captain’ [Liddell Hart] to task for […] manipulating history”.)

According to Connelly, Young and Liddell Hart laid the foundation for the Anglo-American myth, which consisted of three themes: Rommel’s ambivalence towards Nazism; his military genius; and the emphasis of the chivalrous nature of the fighting in North Africa. Their works lent support to the image of the “clean Wehrmacht” and were generally not questioned, since they came from British authors, rather than German revisionists.

MI5 Controversy

On 04 September 2006, MI5 files were released which showed that in early 1944 MI5 had suspicions that plans for the D-Day invasion had been leaked. Liddell Hart had prepared a treatise titled Some Reflections on the Problems of Invading the Continent which he circulated amongst political and military figures. It is possible that in his treatise Liddell Hart had correctly deduced a number of aspects of the upcoming Allied invasion, including the location of the landings. MI5 suspected that Liddell Hart had received plans of the invasion from General Sir Alfred “Tim” Pile who was in command of Britain’s anti-aircraft defences. MI5 placed him under surveillance, intercepting his telephone calls and letters. The investigation showed no suggestion that Liddell Hart was involved in any subversive activity. No case was ever brought against Pile. Liddell Hart stated his work was merely speculative. It would appear that Liddell Hart had simply perceived the same problems and arrived at similar conclusions as the Allied general staff.
