Field Marshal Bernard Law Montgomery, 1st Viscount Montgomery of Alamein, KG, GCB, DSO, PC, (17 November 1887 – 24 March 1976), often referred to as "Monty", was a British Army officer. He first saw action during World War I. He survived a sniper shot through the lung in October 1914. He returned to the front in 1917 as a general staff officer.
During World War II, he successfully commanded Allied forces at the Battle of El Alamein, a major turning point in the Western Desert Campaign during World War II, and troops under his command played a major role in the expulsion of Axis forces from North Africa. He was later a prominent commander in Italy and North-West Europe, where he was in command of all Allied ground forces during Operation Overlord until after the Battle of Normandy. He then continued in command of the 21st Army Group for the rest of the campaign in North West Europe. As such he was the principal field commander for the failed airborne attempt to bridge the Rhine at Arnhem and the Allied Rhine crossing. On 4 May 1945 he took the German surrender at Lüneburg Heath in northern Germany. After the war he became Commander-in-Chief of the British Army of the Rhine (BAOR) in Germany and then Chief of the Imperial General Staff.
While certainly a talented commander, Montgomery's ego and lack of tact in interpersonal relations did him no favours among his foreign allies and in the British Army.
