By all accounts except the minutes, this was a stormy meeting. Antony Beevor suggests that it "perhaps encapsulated the most critical moment of the war, when Nazi Germany might have won". The clash between Churchill and Halifax was now open and Halifax threatened to resign if his views were ignored. Churchill had the full support of Attlee, Greenwood and Sinclair. He had convinced Chamberlain that it was pointless to negotiate but Chamberlain remained cautious about how to reply to Reynaud and Churchill, unlike Greenwood for one, would not oppose Chamberlain about that. Later on, Churchill spoke to Halifax in the garden at 10, Downing Street and managed to calm him.
