Draža Mihailović [SEP] Early life and military career
He was promoted to the rank of lieutenant colonel in 1930. That same year, he spent three months in Paris, following classes at the École spéciale militaire de Saint-Cyr. Some authors claim that he met and befriended Charles de Gaulle during his stay, although there is no known evidence of this. In 1935, he became a military attaché to the Kingdom of Bulgaria and was stationed to Sofia. On 6 September 1935, he was promoted to the rank of colonel. Mihailović then came in contact with members of Zveno and considered taking part in a plot which aimed to provoke Boris III's abdication and the creation of an alliance between Yugoslavia and Bulgaria, but, being untrained as a spy, he was soon identified by Bulgarian authorities and was asked to leave the country.
