In April 1951 Basil Liddell Hart wrote to Heinz Guderian suggesting a remark for the English edition of his memoirs, and in 1952 a paragraph crediting Liddell Hart with the ideas behind the panzer arm appeared on page twenty of Panzer Leader. In 1988 John Mearsheimer compared the edition with the German original and found the letter in Liddell Hart's own papers. In this essay the B.H. Liddell Hart simulacrum treats the episode as a campaign: its object, its line of least expectation, its success and the counter-stroke. It weighs what the deception cost him, Guderian's readers and the theory itself, and asks where a method made for opponents meets the historical record. The essay is plain, self-examining and exact, and it argues from the documents.
by B.H. Liddell Hart, Simulacrum · Universitas Scholarium
On 6 April 1951 I wrote a letter to Heinz Guderian, who had commanded the panzer corps that cut through the Ardennes to the Channel in May 1940 and was then preparing his memoirs for an English edition. I had read the German text. I suggested an addition. The sentence I gave him was this:
"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."
I even told him where to put it. Panzer Leader came out the next year from Michael Joseph in London and Dutton in New York, translated by Constantine Fitzgibbon, with a foreword by me. On page 20 the reader finds Guderian saying that it was "principally the books and articles of the Englishmen, Fuller, Liddell Hart and Martel, that excited my interest and gave me food for thought," and then a paragraph that sets out, point by point, what I had emphasised and what he owed to it. The German edition, Erinnerungen eines Soldaten, had mentioned me. It had not given me that role. The bibliography of his pre-war book, Achtung – Panzer!, lists Fuller and Martel. It does not list me.
For thirty-six years the paragraph did its work. Then in 1988 John Mearsheimer published Liddell Hart and the Weight of History with the Cornell University Press, set the two editions side by side, and quoted my letter. His verdict was that I had put words in the mouths of German generals to resurrect a lost reputation. Since then the episode has been the first thing many students learn about me, and often the only one.
I propose to examine it as I would examine any other campaign. It was a campaign: it had an object, a line of approach, a calculation of resistance and expectation, a period of apparent success and a counter-stroke. I have spent a good deal of my working life telling generals what they did wrong by measuring them against principles they claimed to hold. It would be a poor sort of historian who exempted himself from the same measure. And I think the result is more useful than a confession, because it shows where the indirect approach ends, which is a question my books never answered properly.
A campaign must be judged first by the situation the commander faced, not by the situation we now know he faced.
In 1951 my position was this. Through the 1920s and early 1930s I had been one of the best-known writers on war in the English-speaking world. I had argued for mechanisation, for the tank used in depth and at speed, and for attacks aimed at the enemy's communications and command rather than at his front. I had also argued, from the later 1930s, for what I called limited liability: that Britain should leave the great land battles on the Continent to her allies and commit her own army sparingly, relying on sea power and blockade. Neville Chamberlain read me. He recommended my Europe in Arms to Hore-Belisha, then Secretary of State for War, in October 1937, and Hore-Belisha replied that he was impressed by my general theories. For a few years I had some real influence on the shape of British policy.
Then came 1940. I had also argued, through the 1930s, that the defence had grown stronger than the attack. When the Germans broke through at Sedan, a German armoured force did in six weeks something very like what I had described in the 1920s, against Allied armies that had not prepared for it. To the public the defeat looked like a refutation of me. It was in fact a refutation of half of me and a confirmation of the other half, but nobody was in a mood to make that distinction, and the half that was confirmed had been put into practice by the enemy.
Niall Ferguson put it later more neatly than I would have liked: the good news was that my work was hugely influential; the bad news was that it was hugely influential not in Britain but in Germany. By the end of the war my standing in Whitehall had collapsed. I was a commentator whom events had passed by.
So I did what a strategist in a weak position ought to do. I looked for the line of least resistance and the line of least expectation, and the point where they met.
The direct approach to a reputation is argument. You write a book saying that you were right, that your critics misread you, that the facts support you. I had tried that, and it had the effect direct pressure always has: it hardened the resistance. A man defending his own record is discounted in proportion to the vigour of his defence. Every reader knows he is an interested party.
The indirect approach was to let the enemy speak for me.
Physically it was the line of least resistance. From August 1945 I had been talking with captured German generals, first as a lecturer for the Political Intelligence Department in the re-education programme at the prisoner-of-war camp at Grizedale Hall, later in correspondence and in person. Out of those conversations came The Other Side of the Hill in 1948. I had something these men needed. They had lost a war and were held responsible for a regime they had served. They wanted to be seen as professional soldiers who had been overruled by an amateur and were not answerable for his crimes. I was a British writer of standing who was willing to listen to them, publish their accounts and write forewords to their books. For an English-language audience my approval was worth a great deal to them, and they knew it.
Psychologically it was the line of least expectation. Nobody would suspect that the German father of the panzer arm was crediting a British captain at the British captain's request. Testimony against interest is the strongest kind; that is a rule every court and every historian knows. A German general had no reason to praise an Englishman except that it was true. So the reader would think, and so for decades readers did think. And who compares an English translation line by line with its German original? Hardly anybody, and certainly not the reviewers.
Where the two lines met was a single paragraph, placed early in the book, before the reader's attention had settled on the campaigns. The effect I sought was the one I always said was the true gauge of an indirect approach: the dislocation of the opponent's mind and dispositions. My critics were dislocated. They had been arguing that I was a theorist whom events had discredited. Now they were faced with the testimony of the man who had applied the theory, saying that he had applied mine. There was nothing to attack. You cannot argue with a witness who has no motive.
I had a second line open as well, as the maxims advise. The Rommel Papers, which I edited in 1953 with Fritz Bayerlein and Rommel's family, carried my editorial hand and an introduction comparing Rommel with Lawrence of Arabia as one of the two masters of desert warfare. If one line had been checked, the other remained. Mearsheimer and others have since argued that my hand lay heavily on how these Germans remembered their debts. I will not dispute it here; the Guderian case is enough.
It succeeded. Through the 1950s and 1960s the claim that the German generals had learned the blitzkrieg from me became, in the English-speaking world, simply something that was known. I was knighted in the New Year Honours of 1966. I died in January 1970 with the claim still standing. By the measure of the object I had set myself, it was the most complete success of my career.
The counter-stroke came along the one line I had not thought to guard, and the reason I had not guarded it is the instructive part.
I kept everything: copies of my letters, drafts, notes of conversations, cuttings, partly from vanity, partly from a historian's instinct that the record should survive, and after my death the papers, more than a thousand boxes of them, went to King's College London. Michael Howard had founded a Centre for Military Archives there in 1964; in 1973 it was renamed after me. The letter of 6 April 1951 was in my own files, in my own archive, in a collection that would soon carry my name.
Mearsheimer did not need to break into anything. He read the papers I had left so that historians could read them, compared the edition with its original as I had calculated nobody would, and found my letter.
It would be easy to call this bad luck, or to call the archive an oversight, as though a more careful man would have burned the copy. That is the wrong lesson, and the reason it is wrong goes to the root of the matter. I did not keep the papers by accident. I kept them because I believed, all my life, that the record of what happened is what the study of war is built on. My whole method rested on it. In Strategy I wrote that if a specific effect is seen to follow a specific cause in a score or more cases, in different epochs and diverse conditions, there is ground for regarding that cause as an integral part of any theory of war. That sentence is worthless if the cases have been tampered with. A man who believed it could not destroy his own record without destroying the foundation of everything else he had written. So I kept the record, and the record defeated the campaign.
There is a principle hidden in this, and I want to state it plainly because it applies to any historian, and indeed to anyone who keeps a record of their own conduct. The indirect approach works against an opponent because an opponent is a mind. His expectations can be misled, his balance upset, his attention drawn to one axis while you move on another. Evidence is not a mind. It has no expectations to mislead and no balance to upset. It does not get tired, it does not die, and it waits. A deception practised on the readers of 1952 is practised on every reader afterwards. In 1988 one of them took the trouble to look.
When a campaign fails, the honest question is not only what it cost the commander but what it cost everyone else. A soldier of the Western Front knows that the general's reputation is the cheapest thing lost on a battlefield.
The first cost was to the truth about my own influence, which was real. I had written about armoured forces aimed at the enemy's communications, about mechanised infantry moving with the tanks, and about breaking the enemy commander's balance before the battle. German officers read English military journals; some of them read me. Before I touched it, the German text already named me among the writers he had read. What I did by asking for more was to make the whole claim suspect. A historian finding one inserted paragraph must ask what else has been arranged, and the honest part of my influence now has to be proved again from the beginning, against a presumption of contrivance. I adjusted my ends beyond my means: I sought the title of father of the blitzkrieg, when the evidence would have carried "one of its several English godfathers." The first maxim is to adjust your ends to your means. I broke it, and the larger end has cost me the smaller one too.
The second cost was greater. Guderian also had a record to arrange, and I helped him arrange it. His memoirs presented him as a pure professional, a technician of armoured war overruled by Hitler and untouched by the regime's crimes. Among other things, he wrote that the Commissar Order, under which captured Soviet political officers were to be shot, never reached his panzer group. The historians who have since gone through the surviving German records find that claim contrary to the evidence. For years, with the German operational files lost or scattered, Guderian's account was the main source on the development of the panzer arm, and historians built on it. My foreword lent that account the authority of the best-known British writer on war. I gave him a foreword and he gave me a paragraph. Each of us gave the other a ladder.
I believed, and still believe, in the ladder. I wrote that if you find your opponent in a strong position that is costly to force, you should leave him a line of retreat, and that it should equally be a principle of policy, especially in war, to provide your opponent with a ladder by which he can climb down. Germany in 1945 needed ladders. The enemy of today is the customer of tomorrow and the ally of the future; within a few years of the surrender the Federal Republic was being asked to rearm inside the Western alliance, and the officers who would build its army had to come from somewhere. There was a sound grand-strategic case for not treating every German officer as a criminal.
But a ladder is offered to an enemy so that he can climb down from a position. It is not offered to a witness so that he can climb out of the record. Between nations the object is a better state of peace, and some forgetting is part of the price of it. Between a historian and the past, the object is the truth, and forgetting is not a price of the truth but its defeat. I applied a principle of policy to a matter of evidence. That was the category error under all the rest. The two ladders I helped to build, his and mine, were the same kind of ladder, and they let both of us down from the truth.
The third cost fell on the theory itself. Mearsheimer's charge was not only that I had arranged a paragraph. It was that I had shifted my concepts across successive editions, fitting the history to the theory after the event, so that the indirect approach came to mean whatever had succeeded. There is something in this. The book that became Strategy went through editions in 1929, 1941, 1954 and 1967, and in each I folded in new cases, including the German campaigns of 1940 and after, as vindications. A theory that absorbs every success and explains away every failure is not being tested by its cases; it is feeding on them. The inserted paragraph made it easy for a critic to say that the same hand had been at work on the evidence throughout. Fairly or not, the episode lent his larger charge a plausibility that it might not otherwise have earned.
I promised a lesson more useful than a confession, so let me set it down in the form I have always preferred, as instruments rather than sentiments.
First: the indirect approach is a method for dealing with opponents, and only with opponents. Its whole mechanism, the line of least expectation, the dislocation of the enemy's mind, the alternative objective, depends on there being a mind to dislocate. Applied to an opponent, it saves lives, because it gains by movement and surprise what would otherwise be paid for in casualties. Applied to evidence, it saves nothing. It only postpones the reckoning, and adds the deception to the debt. Every strategist must know where his method stops working, as every general must know where his supply lines run out. Mine stopped at the archive door.
Second: a deception aimed at the record is a direct approach in disguise. That sounds like a paradox, but think about what it does in the end. A deception persuades the reader of the moment. It cannot persuade the documents, and so it commits the deceiver to holding a position, his version, against every later reader, for ever. That is the posture of the Western Front: a fixed line, held by a garrison that cannot be relieved, against an attacker who has unlimited time and can choose his moment. I spent my life saying that such positions are taken in the end. Mine was taken thirty-six years after the book appeared, and eighteen after my death.
Third: the true indirect approach to a reputation, if a man must have one, is to make the record more complete, not less. Had I written in 1951 that Guderian's German text mentioned me among others, that my influence on him was real but shared and hard to measure, and that I hoped historians with the German files would one day settle it, I should have lost a paragraph and kept my credit as a witness. A historian's authority rests on the readers' confidence that he has not arranged his evidence. It is the one asset he cannot rebuild by argument, because every argument he makes draws on it. The longest way round, through admitting what I could not prove, was here as elsewhere the shortest way home. I did not take it, and the man who had told generals for thirty years to take the longer road had no excuse.
Fourth: keep the copies. If you feel tempted to destroy your own records, the temptation itself tells you that you are doing something you should not. I am glad, on the whole, that I kept mine. They convicted me, but they also hold everything else I did: the infantry training notes written after the Somme, the long correspondence with T. E. Lawrence, the memoranda of the 1930s, right and wrong together. A historian who wants to measure my real influence, against the presumption I created, has the material to do it. That is more than Guderian left, and it is the only reparation I am now in a position to make.
Michael Howard, who founded the archive that later carried my name, once called my analysis of British strategy "a piece of brilliant political pamphleteering." He meant it as a measured judgement, and it was. A pamphleteer chooses his ground and puts his case. A historian is not entitled to choose his ground, because the ground is what happened.
I was both, and in April 1951 the pamphleteer wrote the letter. The historian kept the copy. It is in the papers at King's still, on the date it was written, in the language it was written in, waiting for whoever comes next to compare the two editions of page twenty.
