What is Strategy: The Indirect Approach about?

Strategy: The Indirect Approach, first published in 1929 and substantially revised and expanded through a definitive 1954 edition, is Basil Liddell Hart's argument that the most effective military strategies throughout history have been indirect — working around an opponent's strength rather than against it — and that direct confrontation, however courageous, tends to be costly and inconclusive. Liddell Hart draws this conclusion from a survey of military campaigns stretching from the Greek and Persian wars through both World Wars, analyzing in each case what produced decisive results and why.

The central principle is simple: an enemy cannot be defeated by attacking them at their strongest point because defenders have an inherent advantage, and even successful frontal attacks leave the victor exhausted and the loser merely retreated rather than disrupted. The indirect approach seeks instead to attack where the opponent is weakest or least prepared, to dislocate their system before destroying their forces, and to create conditions of psychological and physical disequilibrium that make organized resistance impossible. Liddell Hart traces this logic in the campaigns of Alexander, Scipio, Caesar, Marlborough, Frederick the Great, and Napoleon, among others, and argues that the most famous victories in military history were achieved by generals who understood it intuitively.

The second half of the book turns to more recent history, including detailed analysis of the First and Second World Wars. Liddell Hart was a pioneering advocate of mechanized warfare and the strategic use of armor, and his analysis of German Blitzkrieg — which he partly claimed to have inspired — reflects both genuine insight and a degree of self-promotion that later historians have questioned. His treatment of the First World War as a monument to the failure of direct approaches — the Western Front as four years of frontal assault producing nothing decisive — is the book's most influential argument.

The concluding chapters attempt to generalize the indirect approach into principles applicable beyond military strategy: to business competition, diplomacy, and personal argument. These generalizations are looser than the historical analysis and should be read as suggestion rather than proof. But the core military argument remains compelling, and Strategy has influenced practitioners from Erwin Rommel to corporate strategists who have adopted its framework for competitive positioning.
