The Tehran Conference was a strategy meeting of Joseph Stalin, Franklin D. Roosevelt and Winston Churchill from 28 November to 1 December 1943, after the Anglo-Soviet invasion of Iran. It was held at the Soviet Union’s embassy at Tehran in Iran. chief discussion centered on the opening of a “second front” in western Europe. Stalin agreed to an eastern offensive to coincide with the forthcoming Western Front, and he pressed the western leaders to proceed with formal preparations for their long-promised invasion of German-occupied France. Military decisions edit The Yugoslav Partisans would be supported by supplies, equipment, and commando operations. The leaders stated that it would be desirable for Turkey to join the war on the side of the Allies before the end of the year. The leaders took note of Stalin’s statement that if Turkey found herself at war with Germany and, as a result, Bulgaria declared war on or attacked Turkey, the Soviet Union would immediately be at war with Bulgaria. The Conference noted that this could be mentioned in the forthcoming negotiations to bring Turkey into the war. The cross-channel invasion of France (Operation Overlord) would be launched during May 1944, in conjunction with an operation against southern France (Operation Dragoon). The latter operation would be undertaken in as great a strength as the availability of landing craft permitted. The Conference further took note of Stalin’s statement that the Soviet forces would launch an offensive (Operation Bagration) about the same time with the object of preventing the German forces from transferring from the Eastern Front to the Western Front. Operation Overlord was to be on 1 June, but the moon and tides required to be delayed to 5 June. The leaders agreed for the military staff of the three powers to keep in close contact with one another in regard to the impending operations in Europe. In particular, a cover plan to mislead the enemy about the operations was to be concocted by the staff concerned. Along with the negotiations and military discussions came a few iconic events Churchill presented a sword from King George VI to Soviet Premier Joseph Stalin on 29 November 1943 during their conference in Tehran. Winston Churchill also celebrated his 69th birthday in Tehran, with President Roosevelt and Marshal Stalin at a dinner party at the British Legation in Tehran on the occasion of Churchill’s 69th birthday on 30 November 1943.
