war broke out in 1939 Maclean was prevented from joining the military because of his position as a diplomat. He was 2nd Secretary in the Foreign Office. Therefore, he resigned from the Diplomatic Service "to go into politics". After tendering his resignation he immediately took a taxi to the nearest recruiting office and enlisted as a Private in the Queen's Own Cameron Highlanders. He was soon promoted to lance corporal and was commissioned in 1941. In that year he became the Conservative MP for Lancaster. In North Africa in 1942, he distinguished himself in the early actions of the newly formed Special Air Service (SAS), where, with Ralph A.

Little was known at the time about Tito: some suspected this was an acronym for a committee or that he might in fact be a young woman. Maclean got to know Tito well, and later produced two biographies of him. Maclean's relationship with Tito's Partisans was not always easy, partly because they were Communist, while he came from an upper class Scottish background, and had witnessed Stalinism in action (see above). As Churchill personally told him, Maclean's mission was not to concern himself with how Yugoslavia was to be run after the war, but "simply to find out who was killing the most Germans and suggest means by which we
