Alexander continues to be a subject of military as well as historical or cultural interest. In modern times, he began as the greatest of Great Captains, then became the inventor of modern mobile warfare, the model for romantic military genius, and, in recent decades, the unlikely precedent for leaders as different as Hitler and Mao Tse Tung. The writers promoting him include both Clausewitz and the contemporary Israeli writer, Martin Van Creveld; his detractors include Frederick the Great of Prussia and the most influential modern British military writer, B. H. Liddell-Hart. Machiavelli, Montaigne, and Montesquieu are among the civilians who join military men in giving opinions of Alexander as both a strategist and a fighter of battles. This chapter begins, however, with Julian, whose dialogue, Caesares, is the first extended comparison of great generals in the Western literary tradition. From there it moves to Machiavelli and thence to Italian as well as French writers, before going on to recent literature dominated by writers in German and English. The chapter ends with speculation as to why Alexander remains an authoritative yet iconoclastic figure in military history.
