Stalin arrived in Potsdam a day late. Claimed he had a small heart attack. Might have been a ruse. It gave the others a day to take a tour of Berlin on July 16 and see the destruction first hand. During the first week of the conference, everyone was jubilant, having won the war – but Truman quickly learned the Russians weren’t going to give in to his demands, and the Allies and Stalin both had secrets. The Allies had a successful test of Trinity, the first atomic bomb. Stalin had Hitler’s body. Of course, the A Bomb wasn’t really a secret. Meanwhile Clement Attlee is there but being ignored by everyone.
