After the German-Soviet War broke out , the Turkish government sent a military delegation of observers under Lieutenant General Ali Fuat Erden to the German Eastern Front and Germany . After the German retreat from the Caucasus , the Turkish government got closer with the Allies and Winston Churchill secretly met with İsmet İnönü at Yenice Train Station , south Turkey on 30 January 1943 , with the intent of persuading Turkey to join the war on the side of the Allies . A few days before the start of Operation Zitadelle in July 1943 , the Turkish government sent a military delegation under General Cemil Cahit Toydemir to Belgorod and observed the exercises of the 503rd Heavy Panzer Battalion and its equipment . But after the failure of Operation Zitadelle , the Turkish government participated in the Second Cairo Conference in December 1943 , where Franklin D. Roosevelt , Winston Churchill and İsmet İnönü reached an agreement on issues regarding Turkey 's possible contribution to the Allies . On 23 February 1945 , Turkey joined the Allies by declaring war against Germany and Japan , after it was announced at the Yalta Conference that only the states which were formally at war with Germany and Japan by 1 March 1945 would be admitted to the United Nations
