The First Washington Conference, also known as the Arcadia Conference (ARCADIA was the code name used for the conference), was held in Washington, D.C., from December 22, 1941, to January 14, 1942. President Roosevelt of the United States and Prime Minister Churchill of the United Kingdom attended the conference. Major decisions included making the defeat of Germany the highest war priority and the establishment of a Combined Chiefs of Staff to coordinate US and British military planning. Representatives of the Allies adopted the Declaration by United Nations, which committed them to make no separate peace with the enemy, and to employ their full resources until victory.
