"On 16th March, 1939, the day after Czechoslovakia fell to pieces and Hitler occupied Prague, I lunched at No. 10 with Neville Chamberlain and Edward Halifax. The Prime Minister said with resignation, but with our solemn approval, "I have decided that I cannot trust the Nazi leaders again." Next day he made a speech to the Birmingham Unionist Association which I described to his P.P.S., Alec Douglas-Home, as being more like an oration by the younger Pitt. Halifax said later that it was he who had insisted on the need for this fighting speech as the prelude to a revolution in foreign policy. I am sure that this was true."
