This is the classic book on war as we know it. During his long life, Basil H. Liddell Hart was considered one of the world's foremost military thinkers. In his writing, he stressed movement, flexibility, and surprise. He saw that in most military campaigns, it was vital to take an indirect approach. Rather than attacking the enemy head-on, one must dislocate their psychological and physical balance. With key examples from World War I and World War II (think trench warfare vs Blitzkreig), Liddell Hart defines the practical principles of waging war—“Adjust your end to your means,” “Take a line of operation which offers alternate objectives”—and proves they are as fundamental in the worlds of politics and business as they are in warfare.
