At this time, the war raged on in Europe and the Pacific and none of these men could know that it would be over in less than two years. Still, there was an understanding that the tide had turned on the Eastern Front and that Russia would prove to be the essential cog in the machine that would eventually win the war. Stalin arrived with confidence, buoyant over his recent victories against the Nazis. Preoccupied with opening a front in southern Europe, Churchill, proved to be of little help to Roosevelt who was ill from the flu and found it difficult to put up a strong resistance to Stalin’s proposals.
Regardless of the implications of the decisions made at this conference, the plans were clear. Operation Overlord, the invasion of France, would take place in May 1944, coinciding with a massive Russian attack on the Eastern Front.
When it came to splitting up Axis-held territory between them, Roosevelt and Churchill agreed to allow Stalin to install governments sympathetic to him in Poland, Czechoslovakia, the Baltic States, and Eastern Europe, thus sealing the fate of millions of people.
The final declarations were made on December 1, 1943 as seen here.
