In the central city of Wuhan, like in many other cities, two major revolutionary organizations emerged, one supporting the conservative establishment and the other opposed to it. The groups fought over the control of the city. Chen Zaidao, the Army general in charge of the area, forcibly repressed the anti-establishment demonstrators who were backed by Mao. However, during the commotion, Mao himself flew to Wuhan with a large entourage of central officials in an attempt to secure military loyalty in the area. On July 20, 1967, local agitators in response kidnapped Mao's emissary Wang Li in what became known as the Wuhan Incident. Subsequently, Gen. Chen Zaidao was sent to Beijing and tried by Jiang Qing and the rest of the Cultural Revolution Group. Chen's resistance was the last major open display of opposition to the movement within the PLA.
