"Chamberlain entered 10 Downing Street determined to reshape British foreign policy in order to confront the mounting threats to European peace. In January 1938 he managed to move Sir Robert Vansittart, the fiercely anti-Hitler permanent undersecretary at the Foreign Office, into a high-sounding but innocuous post as the government’s chief diplomatic advisor. Chamberlain replaced him with the more pliant Sir Alexander Cadogan. The following month, Chamberlain’s highly strung foreign secretary, Anthony Eden, resigned in irritation at the prime minister’s personal diplomacy. His successor was Lord Halifax, a tall, lugubrious Tory peer, whose basic instinct—whether as Viceroy of India dealing with Gandhi or as foreign secretary facing the dictators— was to seek a peaceful compromise. Chamberlain would later discover that Halifax had a will of his own, but initially they formed an effective team. “I give thanks for a steady unruffled Foreign Secretary who never causes me any worry,” the prime minister wrote privately that spring. After securing a rapprochement with Italy in April 1938, Chamberlain hoped to move on to an agreement with Germany, trading territorial concessions in Europe and colonial Africa for firm restrictions on the growth of German military power. This was all part of what he and his colleagues called the “appeasement” or pacification of Europe. And after the war scare of May 1938, it was clear that the Sudeten problem had to be resolved before further progress could be made. Accordingly the British government emerged from France’s shadow as would-be mediator."
