92 years ago today, on September 25, 1933 (August 6, 1933 in the lunar calendar), Chiang Kai-shek launched the fifth "encirclement and suppression" against the Soviet areas. The Kuomintang army built bunkers on the edge of the Central Revolutionary Base Areas On September 25, 1933, Chiang Kai-shek concentrated the 1 million army and 200 aircraft to launch the fifth military "encirclement and suppression" against the Red Base Areas. The force used to attack the Central Soviet Area this time reached 500,000, and these forces were divided into four lines: Gu Zhutong was the commander-in-chief on the north road, and Chen Cheng was also the commander-in-chief of the former enemy. Commanded about 22 divisions and two brigades: it was the main force for the "encirclement and suppression" of Chiang's army; He Jian was the commander-in-chief on the western route, commanding about 14 divisions and two brigades; Chen Jitang was the commander-in-chief on the southern route, commanding about 14 divisions and two brigades; Chiang Dingwen was the commander-in-chief on the eastern route. In view of the failure of the first four military "encirclement and suppression", Chiang Kai-shek changed the "long drive and straight forward" combat method. Adopting "step by step, fortress advance" in an attempt to gradually tighten the Soviet area, consume the living strength of the Red Army, and finally seek a decisive battle of the main force of the Red Army to achieve the purpose of destroying the Red Army. On the same day, four divisions of the Kuomintang North Road Army attacked Lichuan, a strategic At this time, the temporary central government had moved to the central base of the Soviet Area and reorganized the Red Army. Wang Ming's "left" adventurist leadership and extremely wrong strategy had achieved dominance in the Red Army. When the anti-" encirclement and suppression "began, the enemy occupied Lichuan, and the" left "adventurists first implemented military adventurism, so that the Red Army attacked the strong positions of the enemy in the White District, such as saltpeter and Zixi Bridge, north of Lichuan, and failed to fight again and again. Afterwards, they were intimidated by the enemy's superiority and adopted defensive conservatism, so that the Red Army was fortified everywhere and did not dare to take the initiative to lure the enemy deep and gather and destroy them. After Chiang Kai-shek suppressed the Fujian Incident, he immediately transferred his main force to attack Guangchang." The left "adventurists advocated using a fortress against a fortress, but failed to win. They lost Guangchang in April 1934. Afterwards, they advocated dividing their troops into six lines, defending the whole line, and fighting with the enemy to consume, leaving themselves passive. After a year of hard work, the Red Army failed to break the enemy's" encirclement and suppression ". The" left "adventurists turned into escapists again, and in October 1934 hastily decided that the central leadership and the main force of the Red Army should withdraw from the base area. The fifth anti-" encirclement and suppression" failed, and the Red Army was forced to go on a long march and carry out a major strategic shift.
