The attempted settlement of the Sudeten crisis, culminating in the Munich Agreement, was the climax of the appeasement policy. Between September 15 and 30, 1938, Chamberlain traveled to Germany three times to meet Hitler. From the last meeting, held at Munich on September 30, he took back what he believed to be an agreement that the German portions of Czechoslovakia constituted Hitler’s last territorial claim in Europe and that Germany, as well as Britain, would renounce war as a means of settling international claims. He had, he said with some pride, brought “peace for our time.”

Chamberlain’s policy failed because he believed that Hitler sincerely aimed only at reuniting Germans, whereas in fact Hitler’s appetite for territory, particularly to the east, was unlimited. On March 15, 1939, the German army, virtually without warning, occupied the rest of Czechoslovakia, even though it was not inhabited by Germans. On March 18 Chamberlain, distinctly angry, made an announcement that amounted to the end of appeasement; in the following weeks Britain offered a guarantee of Polish territory (where Hitler would clearly be looking next), signed a military alliance with Poland, and undertook serious preparation for war, including the first peacetime military conscription.

World War II

The Polish crisis precipitated the war. Through the summer of 1939, German propaganda grew more strident, demanding cession to Germany of the city of Gdańsk (Danzig) while gradually escalating demands for special rights in, and finally annexation of, the Polish corridor. Because the only country able to defend Poland was the Soviet Union, a British-French mission in the summer of 1939 began negotiations for a treaty with Soviet ruler Joseph Stalin. Poland, however, announced that it would not allow Soviet troops to enter Polish territory, even for the purpose of defending the country against Germany. Hitler put a stop to these negotiations on August 23 when he announced the Nonaggression Pact" class="md-crosslink">German-Soviet Nonaggression Pact. On September 1 German troops invaded Poland. Britain and France declared war on Germany on September 3.

The phases of war

From the British perspective, World War II fell readily into three distinct phases. The first, the so-called phony war and the period of German victories in the west, ended with the decision of France on June 18, 1940, to ask for an armistice with Germany. The second, heroic phase, when Britain stood alone, began with the battle for survival in the air over the British Isles and ended in the first week of December 1941 with the successful Soviet defense of Moscow after Hitler’s attack on June 22 and with the Japanese declaration of war on the United States and the British Empire on December 7. Then followed what Churchill termed the period of the Grand Alliance, lasting from December 1941 until Germany’s capitulation in May 1945.

Perhaps the most important event of the first phase was the announcement on September 3, 1939, that Churchill, assumed to have reached the end of his career in 1936 as a result of his having embraced the king’s cause during the abdication crisis, would reenter the government as first lord of the admiralty. Churchill thus was in charge of the Royal Navy on April 9 and 10, 1940, when Hitler without warning overran Denmark and Norway, greatly extending his northern flank and virtually destroying the naval blockade of Germany that had been established at the beginning of the war.

The Norwegian campaign destroyed the Chamberlain government. The obviously poor planning and the incapacity of the British forces in an area where the Germans were at a serious disadvantage caused a rebellion within the Conservative Party. A bitter debate lasting from May 7 to May 9, 1940, resulted in Chamberlain’s resignation the next day. Although Churchill himself, as first lord of the admiralty, was heavily involved and did not attempt to deny his responsibility, Chamberlain quickly discovered that the coalition government he hoped to establish with either himself or Lord Halifax as prime minister could, at the insistence of the Labour Party, be headed only by Churchill. Thus, on May 10 Churchill was announced as prime minister. Chamberlain, to his immense credit, consented to remain in the cabinet and to control, on Churchill’s behalf, the Conservative Party.
