the Blitz John Colville Luftwaffe
The Luftwaffe altered its strategy from 7 September 1940 and began the Blitz, which was especially intensive through October and November. Churchill's morale during the Blitz was generally high and he told his private secretary John Colville in November that he thought the threat of invasion was past. He was confident that Great Britain could hold its own, given the increase in output, but was realistic about its chances of actually winning the war without American intervention.
