On September 11, 1939, just a few scant days after Hitler inaugurated the Second World War by unleashing the German Army in Poland, U.S. President Franklin D. Roosevelt penned a brief but important message to Britain's First Lord of the Admiralty, Winston Churchill. Roosevelt did not know it at the time, but his initiative would mark the beginning of one of the most extraordinary relationships in political history, a relationship marked by an intimate correspondence unparalleled among national leaders, a relationship which, in due course, would lead to the establishment of a military alliance unique among sovereign states.
FDR wrote to Churchill because he was looking for information about the War, and because he wished to establish contact with a British leader who appeared to be a likely candidate for Prime Minister, in the event that the current Prime Minister, Neville Chamberlain, should resign or be forced from office. FDR's intuition would prove correct. On May 10 1940, the very day on which the German Army finally launched its long anticipated attack on France and Low Countries following the six-month period known as the "phony war," Winston Churchill became Prime Minister of Great Britain.
From the start, the correspondence between the two men was marked by an easy and affable writing style that foreshadowed the friendship that was to come. In his very first letter, FDR noted their common experience in Naval matters, (FDR had served as Assistant Secretary of the Navy under U.S. President Woodrow Wilson during World War I), as well as their common interest in history. Churchill responded with alacrity and mild humor, choosing the transparent code name "Naval Person," that he would later change to "Former Naval Person" once he had left the Admiralty and moved to the Prime Minister's Residence at number 10 Downing Street.
Over the course of the war the two men would exchange thousands of messages, telephone calls, and indirect third party exchanges. They would also meet in person nine times, including the two famous meetings with Soviet Premier Joseph Stalin at Teheran and Yalta, and in the process initiate a new means of carrying out international relations that what we now call "summit diplomacy." The first of these summits took place off the coast of Newfoundland in August 1941, and resulted in the Atlantic Charter, a set of guiding principles intended to govern relations among states with the coming of peace. The last took place at Yalta, in the Crimea, where the "Big Three" issued the "Declaration on Liberated Europe," and attempted to deal with the difficult question of the fate of postwar Poland, where the war began six years before.1
The friendship that developed between Churchill and Roosevelt was not without its difficulties, and it is important not to lose site of the fact that the primary responsibility of both men was to look after national interests. This inevitably led to tensions, which at times became quite pronounced. Serious differences arose, for example, over the question of when and where to open the second front in Europe, and a host of other issues, particularly with respect to economic matters.
