On August 1934, the Red 6 Army Corps led by Ren, Xiao Ke and the Central Revolutionary Military Commission of the Chinese Soviet Union left the Hunan-Jiangxi Soviet Area to prepare for the Western Expedition. In the same year1October 24th, Huang Mu and He Long's Red 3 Army joined forces in Yinjiang County, Guizhou Province. The Red 3 Army resumed the Red 2 Army designation, with He Long as the head and political commissar. They unified and commanded the two legions to take active actions, and created the Soviet area of Hunan, Hubei, Sichuan and Guizhou, which effectively attacked and contained the Kuomintang army and cooperated with the Long March of the Central Red Army. 1September 1935, around the Red 2 and Red 6 Legions, * * attracted about 200,000 Kuomintang troops from the 130 regiment, and the scope of the Soviet area was shrinking.
L 19 10/9, the Red Second Army Corps and the Red Sixth Army Corps 17 people set out from Liu Jiaping and other places in Sangzhi County, Hunan Province, breaking through the tight encirclement and starting a strategic shift. After two months of marching, we arrived in Shiqian, Zhenyuan and Ping Huang in June 1936 and June 1 mid. But there are few residents in this area, food is difficult, and the enemy is in hot pursuit. Therefore, the Red Army Corps and the Red Army Corps decided to cross the Wujiang River to the west and create a new Soviet area in the western Guizhou and Bijie areas. After finding out the action intention of the Red Army, the Kuomintang army mobilized a large number of troops to intercept the "encirclement and suppression" in the Yunnan-Guizhou-Sichuan border region. It is also difficult for the Red Second and Red Sixth Army Corps to gain a foothold in Qianxi and Bijie. On February 27th, they went west again and entered Mount Wumeng. Relying on the deep mountains and dense forests, I wandered like hide-and-seek among the pursuers of the enemy's fifth column 10 divisions, and I was so elusive that I was exhausted after dragging the enemy for more than a month. In late March, it was surrounded by high light and entered Panxian and Xingyi areas southward. On March 30th, Zhu De, Commander-in-Chief of the Red Army, and Zhang, General Political Commissar, called the Red Second Army and the Red Sixth Army to cross the Jinsha River to join forces with the Red Fourth Army in Ganzi area. The Red Army Corps and the Red Army Corps immediately marched westward to Yunnan, crossed the Pudu River in the north of Kunming, passed through Chuxiong, Zhennan (now Nanhua, Yunnan), Yao 'an, Xiangyun, Binchuan and Lijiang, and headed for the upper reaches of Jinsha River. From April 25th to 27th, I crossed the Jinsha River in Shigu and Judian, leaving the enemy behind. Then he crossed the Snow Mountain Canyon and the Hengduan Mountains, overcoming difficulties such as cold, lack of oxygen and lack of food, and arrived in Derong and Batang in early May. In early June, he joined forces with the Red 32 Army in the south of Physico-chemistry, and on July 2, he joined forces with the main forces of the Red Fourth Army in Ganzi.
On July 5th, Zhongge Military Commission ordered the Red 2 and Red 6 Legions to form the Red 2 Army, and incorporated the Red 32 Army into the Red 2 Army organizational system, with He Long as commander in chief, political commissar, Xiao Ke as deputy commander and deputy political commissar. After the meeting of the two front armies, Zhu De, Liu Bocheng (Chief of Staff of the Red Army), Ren, He Long, etc. Unite the commanders to defeat Zhang's separatist forces and go north together on orders from the Central Committee of the Communist Party of China. The two armies formed three columns, starting from Ganzi, Luhuo and other places, then passing through the vast grassland and crossing the natural barrier Lazikou, and in September, they captured Min County, Tongwei County, Chengxian County, Huixian County, liangdang county County, Kangxian County and other vast areas in Longnan.
During this period, the Red Army formed the Western Field Army and moved to the Shaanxi-Gansu-Ningxia Border Region to join the Red Second and Red Fourth Army in the north.
