General, GCB CBE DSO & Bar. He was a senior British Army officer who also held the NATO position of Deputy Supreme Allied Commander Europe (DSACEUR). He has been described as a popular and affable man. The Guardian newspaper, in his obituary, sums up his personality and how it influenced what he, and those he worked with, accomplished in his career: "John Mogg's large frame was combined with an exceptionally genial, warm and sympathetic character, which appealed not only to soldiers of all ranks, but to people in every walk of life, whatever their nationality. In his time, he was probably the British army's most popular general, and finished his career in one of Nato's most influential posts, as deputy supreme allied commander (1973-76) at headquarters at Mons, in Belgium. Here, his sound commonsense and even temperament were valuable in balancing the direct approach, and sometimes abrasive personality, of the supreme commander, the US General Alexander Haig." He was educated at Malvern College, and the Royal Military Academy, Sandhurst. At Malvern, he paid more attention to cricket than to his studies, with the result that, instead of taking the entrance exam for Sandhurst, he chose the alternative route of a Y-cadetship in the Coldstream Guards. After three years in the ranks, he was selected for Sandhurst, where he gained the sword of honour in 1936, being commissioned into the Oxfordshire and Buckinghamshire Light Infantry in August 1937. He was a distinguished commander of the 9th battalion Durham Light Infantry from the Invasion of Normandy to the defeat of Germany. He commanded the 10th Battalion The Parachute Regiment between 1950 and 1952. He was later a brigade commander in the Malayan Emergency before becoming Commandant of the Royal Military Academy Sandhurst in 1963 and Commander of I Corps in Germany in 1966. He went on to be General Officer Commanding Southern Command in 1968, General Officer Commanding, Army Strategic Command later that year and, finally, Adjutant-General to the Forces in 1970. With NATO, he was DSACEUR between 1973 and 1976.
