Field Marshal Bernard Montgomery was a British Army officer who achieved international fame for his services as an Allied commander in World War II. A highly experienced army officer, he had served as a junior officer in the Royal Warwickshire Regiment during the World War I. He sustained injuries when he was shot by a sniper yet he returned to the war front as soon as he recovered in a display of courage and patriotism. Born as the son of a clergyman, Montgomery had a difficult childhood growing with up a physically abusive and indifferent mother. He became a bully as a result of his troubled childhood and was almost expelled from the Royal Military College, Sandhurst, because of his unruly and violent behavior. Over time, he evolved into a disciplined and courageous young man and was commissioned into the Royal Warwickshire Regiment as a second lieutenant. This marked the beginning of his long and illustrious career which saw him serve in both the World Wars. Recognized as a first-rate trainer of troops following his services in World War I, he had been given the command of the 8th Infantry Division in Palestine during World War II. In the post war period, he became deputy commander of the Supreme Headquarters of NATO, serving for seven years.
