Field Marshal Sir Claude John Eyre Auchinleck, GCB, GCIE, CSI, DSO, OBE was a British Army commander during the Second World War. He was a career soldier who spent much of his military career in India, where he rose to become Commander-in-Chief of the Indian Army by early 1941. In July 1941 he was appointed Commander-in-Chief of the Middle East Theatre, but after initial successes, the war in North Africa turned against the British, and he was relieved of the post in 1942 during the crucial Alamein campaign.
In June 1943, he was once again appointed Commander-in-Chief, India, where his support through the organisation of supply, maintenance and training for William Slim's Fourteenth Army played an important role in its success. He served as Commander-in-Chief, India until the Partition in 1947, when he assumed the role of Supreme Commander of all British forces in India and Pakistan until late 1948.
