During the Second World War Douglas clashed with other senior commanders over strategy in the Battle of Britain. Douglas argued for a more aggressive engagement with a 'Big Wing' strategy i.e. using massed fighters to defend the United Kingdom against enemy bombers. He then became Air Officer Commanding-in-Chief of Fighter Command in which role he was responsible for rebuilding the command's strength after the attrition of the Battle of Britain, but also for bringing it on the offensive to wrest the initiative in the air from the German Luftwaffe.
