The conference was held between the 4th and 11th February 1945 in the Livadia Palace at Yalta.......a Black Sea resort in the Crimea. It was the second of three major conferences during WW2 between the "big three" powers.

At the conference the three leaders agreed to demand Germany’s unconditional surrender and to set up four zones of occupation to be run by their three countries and France.
British Prime Minister Winston Churchill, U.S. President Franklin D. Roosevelt and Soviet Premier Joseph Stalin
Despite the attractive appearance of the palace, it had been left by the Germans infested with vermin and according to one description, "If we had spent ten years on research we could not have found a worse place than Yalta. It is good for typhus and other deadly lice which thrive in those parts".
