Field Marshal Bernard Law Montgomery, 1st Viscount Montgomery of Alamein, KG, GCB, DSO, PC (pronounced /məntˈɡʌmərɪ əv ˈæləmeɪn/; 17 November 1887 – 24 March 1976), often referred to as "Monty", was a British Armyofficer. He saw action in World War I, and during World War II he successfully commanded Allied forces at the Battle of El Alamein, a major turning point in theWestern Desert Campaign. 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, and was the principal commander forOperation Market Garden. After the War he became Commander-in-Chief of the British Forces of Occupation in Germany and then Chief of the Imperial General Staff.
The First World War began in August 1914 and Montgomery moved to France with his regiment that month. He saw service during the retreat from Mons, during which half his battalion was destroyed. At Méteren, near the Belgian border at Bailleul on 13 October 1914, during an Allied counter-offensive, he was shot through the right lung by a sniper and was injured seriously enough for his grave to be dug in preparation for his death. A Platoon sergeant came to assist him but was killed. He fell on Montgomery. The German sniper fired at him until sunset. The body of the sergeant protected Montgomery and took most of the enemy fire. Montgomery was hit once more though, in the knee.[36] He was awarded the Distinguished Service Order for gallant leadership. The citation for this award, published in the London Gazette in December 1914 reads:

Conspicuous gallant leading on 13th October, when he turned the enemy out of their trenches with the bayonet. He was severely wounded.[37]
