Edouard Daladier, prime minister at the start of the Second World War, did not leave his apartment near the Arc de Triomphe and worked at the War Ministry. During the war the government moved to the city of Vichy, but on 21 August 1944, it was in Paris that the resistance leader Yvon Morandat and his companion seized the "Government Mansion", the Hôtel Matignon. In their haste they even confused the Avenue Matignon, located on the Right Bank of the Seine, with the Hôtel Matignon, situated on the Left Bank.
