Thomas Henry Wintringham (15 May 1898 – 16 August 1949) was a British soldier, military historian, journalist, poet, Marxist, politician and author. He was a supporter of the Home Guard during the Second World War and was one of the founders of the Common Wealth Party. Biography Early life Tom Wintringham was born 1898 in Grimsby, Lincolnshire. He was educated at Gresham's School, Holt, and Balliol College, Oxford. In 1915 he was elected to a Brakenbury scholarship in History at Balliol, but during the First World War postponed his university career to join the Royal Flying Corps, serving as a mechanic and motorcycle despatch rider. At the end of the war he was involved in a brief barracks mutiny, one of many minor insurrections which went unnoticed in the period. He returned to Oxford, and in a long vacation made a visit of some months to Moscow, after which he returned to England and formed a group of students aiming to establish a British section of the Third International, a Communist party. As the party was formed, Wintringham graduated from Oxford and moved to London, ostensibly to study for the bar at the Temple, but in fact to work full-time in politics. Political career and the Spanish Civil War In 1923, Wintringham joined the recently formed Communist Party of Great Britain. In 1925, he was one of the twelve CPGB officials imprisoned for seditious libel and incitement to mutiny. In 1930, he helped to found the Communist newspaper, the Daily Worker, and was one of the few named writers to publish articles in it. In writing for the Communist party's theoretic journal Labour Monthly, he established himself as the party's military expert. In LM articles and in booklets on the subject, Wintringham formed the arguments against Air Assault and called for air raid precautions several years before the bombing of Guernica. His arguments were the basis for the most successful of the Communist Party's wartime campaigns, that for ARP provision, and shaped government policy on the issue in the years leading up to the war. Although at the centre of the CPGB organisation, he was often at odds with Party policy, believing in a communism of alliance and co-operation, rather than the dominant Comintern ideology of "class against class". Wintringham's ideas became party dogma when the Comintern announced the 'Popular Front', a form of communism Wintringham was prepared to fight
