What did Churchill and Roosevelt do on board the USS Augusta?

President Roosevelt met with British Prime Minister Churchill—their first of eleven wartime meetings—aboard the USS Augusta on August 9, 1941. The meeting between the two leaders culminated in a joint policy statement which later became known as the Atlantic Charter.
The charter contained a number of goals to which the United States and Great Britain would commit themselves in the event of a global war. Although the war in Europe was already under way, the conflict had yet to take on the truly international dimensions of the latter part of World War II. The meeting between FDR and Churchill took place at a time when the United States had yet to enter the war; Pearl Harbor was still less than four months away.
The goals set out in the Atlantic Charter were:
No territorial aggrandizement;
No territorial changes against the wishes of the people;
A respect for the principle of national self-determination;
Restoration of self-government to those deprived of it. (Such as European countries invaded and occupied by the Nazis, for example);
Reduction of trade restrictions;
Closer global cooperation to improve economic and social conditions;
Freedom from want and fear;
Freedom of the seas;
The abandonment of the use of force;
The disarmament of aggressor nations.
Although not enshrined in any official document, the Atlantic Charter was a hugely significant statement of policy nonetheless. It showed that the United States and Great Britain were already thinking ahead to the postwar period and what kind of world needed to be established. The principles contained in the charter were to a large extent put into practice by the establishment of the United Nations after World War II.
