Prime Minister Pétain moved the government to Vichy (2 July) and had the National Assembly (10 July) vote to dissolve itself and give him dictatorial powers, making the beginning of his Révolution Nationale (National Revolution) intended to "reorient" French society. This was the dawn of the Vichy regime.
The Battle of Britain began in early July with Luftwaffe attacks on shipping and harbors. The United Kingdom rejected Hitler's ultimatum, and the German air superiority campaign started in August but failed to defeat RAF Fighter Command, forcing the indefinite postponement of the proposed German invasion of Britain. The Battle lasted from 10 July to 31 October.
From 22 July 1940 de Gaulle used 4 Carlton Gardens in central London as his London headquarters. His family had left Brittany (the other ship which left at the same time was sunk) and lived for a time at Petts Wood.
