Overview
The Tehran Conference (codenamed Eureka) was a strategy meeting of Joseph Stalin, Franklin D. Roosevelt, and Winston Churchill from 28 November to 1 December 1943. It was held in the Soviet Union's embassy in Tehran, Iran. It was the first of the World War II conferences of the "Big Three" Allied leaders (the Soviet Union, the United States, and the United Kingdom). It closely followed the Cairo Conference which had taken place on 22–26 November 1943, and preceded the 1945 Yalta and Potsdam conferences. Although the three leaders arrived with differing objectives, the main outcome of the Tehran Conference was the Western Allies' commitment to open a second front against Nazi Germany. The conference also addressed the Allies' relations with Turkey and Iran, operations in Yugoslavia and against Japan, and the envisaged post-war settlement. A separate protocol signed at the conference pledged the Big Three to recognize Iran's independence.
Proceedings
The conference was to convene at 16:00 on 28 November 1943. Stalin arrived well before, followed by Roosevelt, brought in his wheelchair from his accommodation adjacent to the venue. Roosevelt, who had traveled 7,000 miles (11,000 km) to attend and whose health was already deteriorating, was met by Stalin. This was the first time that they had met. Churchill, walking with his General Staff from their accommodations nearby, arrived half an hour later
The U.S. and Great Britain wanted to secure the cooperation of the Soviet Union in defeating Germany. Stalin agreed, but at a price: the U.S. and Britain would accept Soviet domination of eastern Europe, support the Yugoslav Partisans, and agree to a westward shift of the border between Poland and the Soviet Union.
The leaders then turned to the conditions under which the Western Allies would open a new front by invading northern France (Operation Overlord), as Stalin had pressed them to do since 1941. Up to this point Churchill had advocated the expansion of joint operations of British, American, and Commonwealth forces in the Mediterranean, as Overlord in 1943 was physically impossible due to a lack of shipping, which left the Mediterranean and Italy as viable goals for 1943. It was agreed Overlord would occur by May 1944; Stalin agreed to support it by launching a concurrent major offensive on Germany's eastern front to divert German forces from northern France.
Iran and Turkey were discussed in detail. Roosevelt, Churchill, and Stalin all agreed to support Iran's government. In addition, the Soviet Union was required to pledge support to Turkey if that country entered the war. Roosevelt, Churchill and Stalin agreed that it would also be most desirable if Turkey entered on the Allies' side before the year was out.
Despite accepting the above arrangements, Stalin dominated the conference. He used the prestige of the Soviet victory at the Battle of Kursk to get his way. Roosevelt attempted to cope with Stalin's onslaught of demands, but was able to do little except appease Stalin. Churchill argued for the invasion of Italy in 1943, then Overlord in 1944, on the basis that Overlord was due to lack of shipping physically impossible in 1943 and it would be unthinkable to do anything major until it could be launched.
Churchill proposed to Stalin a moving westwards of Poland, which Stalin accepted, which gave the Poles industrialized German land to the west and gave up marshlands to the east, while providing a territorial buffer to the Soviet Union against invasion.
Decisions
The declaration issued by the three leaders on conclusion of the conference on 1 December 1943, recorded the following military conclusions:
- The Yugoslav Partisans should be supported by supplies and equipment and also by commando operations.
- It would be desirable if Turkey should come into 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 Turkey or attacked her, the Soviet Union would immediately be at war with Bulgaria. The Conference further took note 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. The latter operation would be undertaken in as great a strength as availability of landing-craft permitted. The Conference further took note of Joseph Stalin's statement that the Soviet forces would launch an offensive at about the same time with the object of preventing the German forces from transferring from the Eastern to the Western Front.
- The leaders agreed that the military staffs of the Three Powers should keep in close touch with each other in regard to the impending operations in Europe. In particular it was agreed that a cover plan to mislead the enemy about these operations should be concerted between the staffs concerned.
Results
The Yugoslav Partisans were given full Allied support, and Allied support to the Yugoslav Chetniks was halted (they were believed to be cooperating with the occupying Germans rather than fighting them). The Communist Partisans under Tito took power in Yugoslavia as the Germans retreated from the Balkans.
Turkey's president conferred with Roosevelt and Churchill at the Cairo Conference in November 1943, and promised to enter the war when it was fully armed. By August 1944 Turkey broke off relations with Germany. In February 1945, Turkey declared war on Germany and Japan, which may have been a symbolic move that allowed Turkey to join the future United Nations.
The invasion of France on 6 June 1944 took place about as planned, and the supporting invasion of southern France also took place (Operation Dragoon). The Soviets launched a major offensive against the Germans on 22 June 1944 (Operation Bagration).
