When did Lin Biao become a Marshal of the People's Republic of China?
Lin Biao
Lin died when a plane carrying him and several members of his family crashed in Mongolia at 3:00 AM[80] on September 13, 1971, allegedly after attempting to assassinate Mao and defect to the Soviet Union. Following Lin's death, there has been widespread skepticism in the West concerning the official Chinese explanation, but forensic evidence conducted by the USSR (which recovered the bodies following the crash) has confirmed that Lin was among those who died in the crash.[7]
