Of the biographies of Lawrence of Arabia, MacLean's, written in 1962 at the time of the film, must, I suppose, be seen as an attempt to capitalize on that frenzy. MacLean is better known today for his adventure novels, such as The Guns of Navarone and Where Eagles Dare.
I knew little of T. E. Lawrence's life. I've seen the film, but remember very little from it. Largely because of my admiration of what filmmaker David Lean did with Dr. Zhivago, I thought I'd watch his other epic, Lawrence of Arabia a little more closely. And I felt that I should familiarize myself with his story beforehand, thus the book selection.
T. E. Lawrence was born in Wales and then grew up in Oxford. He was a very good student, but took more pleasure in going on expeditions by himself on foot or by bicycle, for some reason taking pride in depriving himself of food and sleep during his journeys. He developed a deep interest in the Crusades and the castles thereof, and went to Syria to write his thesis about them. While he was there he lived among poor Arabs and got to know their customs, language and culture. When World War I started, he became an intelligence officer, and his knowledge of and ability to relate with Arab people became a huge asset to the British Army there in its war against the Turks.
As his understanding of the Arab peoples and particularly his ability to relate to and influence their military leaders grew, he rose in importance and rank, eventually becoming a colonel. The book outlines his exploits in the campaign, which were a combination of military tactical smarts, leadership and incredible bravery in brutally dangerous conditions - terrible weather, limited supplies and usually facing an enemy of superior numbers. Most of his battles were carried out by his small band of about 600 Arab soldiers. As the war wound down, his greatest concern was to make sure that Arab lands would come under Arab control.
I'm sure there are biographies that spend more time on Lawrence's early and later life, and go into much more detail about his military career, but this is a good starting place.
