 Mao's attempts to purge the Red Army of those who might potentially oppose him led Mao to accuse Chen Yi, the commander and political commissar of the Jiangxi Military Region, as a counterrevolutionary, provoking a violent reaction against Mao's persecutions that became known as the "Futian Incident" in January 1931.Mao was eventually successful in subduing the Red Army, reducing its numbers from forty thousand to less than ten thousand.The campaign continued throughout 1930 and 1931.
