';Sheds light on the complex personality that has been, in many ways, masked by the legend that emerged during World War II and has grown since.' Col. Gregory Fontenot, ARMY Magazine George S. Patton is one of the most controversial, celebrated, and popular military leaders in American history, and his accomplishments and victories have been greatly documented. Yet Patton spent years in the Army before garnering national attention and becoming a highly-regarded and respected military leader. Drawing upon Patton's papers and archival documents in the National Archives, this is an early-career biography of the eminent military leader. It begins with his exploits as a relatively junior but ambitious Army officer who, due to his family's wealth and influence, was able to join General John J. Pershing's American Expeditionary Force (AEF). This assignment would ultimately change his life in two ways: it would make Pershing the mentor Patton would emulate for the rest of his life, and it would catapult his military career as the first tanker in the USArmy. This study follows Patton's trajectory, from the creation of the Tank Corps and the Light Tank School, to Patton's eventual successes and injuries during the Battle of Saint Mihiel, the attack into Pannes, and the Meuse-Argonne Offensive. The experience Patton gained in World War I was seminal in his evolvement as a leader and laid the groundwork for not only his own personal future triumphs but also for the success of the entire U.S. Army armored forces in World War II. ';No one can really understand the Patton of World War II until they know about the man who fought through the First World War.' Thomas Bruscino, US Army War College
