1September 25th, 933 to1June, 934, Chiang Kai-shek mobilized about100000 troops and adopted the new strategy of "fortress doctrine" to carry out a large-scale "encirclement and suppression" of the central revolutionary base areas.

At this time, Wang Ming's "Left" dogmatism occupied a dominant position in the Red Army, refused to accept Mao Zedong's correct suggestion, and replaced guerrilla warfare and mobile warfare with positional warfare.

Put forward the policy of "keeping the enemy out of the country", trying to control the enemy outside the Soviet area with positional warfare and regular warfare and hold every inch of the Soviet area. At this time, Li De, a military consultant sent by * * * Production International, arrived in the Central Soviet Area from Shanghai and directly mastered the military command of the fifth counter-campaign against "encirclement and suppression".
