B.H. Liddell Hart

British military historian and strategist — author of Sherman, Scipio Africanus, and The Strategy of Indirect Approach — who argued for armored warfare and blitzkrieg tactics after WWI and became the most influential 20th century military theorist.

Creates the indirect approach as military strategy doctrine — Liddell Hart's argument (that the most efficient military strategy attacks the enemy's will and supply lines indirectly rather than engaging armies directly) is the dominant framework in 20th century Western military thinking; his blitzkrieg advocacy influenced German armored doctrine.
