B.H. Liddell Hart

B.H. Liddell Hart was a person who was really interested in wars and how they happened. He studied lots of things about wars, like how soldiers moved around and how they fought, and he even talked to lots of soldiers to learn more about it.

One thing that Liddell Hart thought was really important was something called "strategy." Strategy is like a plan for a war. It's like playing a really big game of chess, but instead of moving pieces around a board, armies move around in real life.

Liddell Hart wrote lots of books about strategy, and lots of important people who worked in the military read his books and learned from him. They used his ideas to help them plan their own wars, and lots of people believe that he was one of the most important war strategists in history.
