During the Agrarian Revolution, peasant uprisings led by the Communist Party of China surged, and a newly founded Red Army team in western Fujian, which was mainly composed of peasants, had a complex composition, and was mixed in quality, came into being - the Red Army Independent Battalion. In response to various trends of thought in the revolutionary armed forces at that time, the Red Fourth Army held the Ninth Congress of the Red Fourth Army of the Communist Party of China in Gutian (known as the Gutian Conference in history) after entering Fujian. The conference sorted out various non-proletarian trends of thought that existed in the Red Army at that time, and clearly put forward the purpose of the party commanding the gun and building the army politically. Under the guidance of the spirit of the Gutian Conference, the Red Army Independent Battalion was trained and effectively improved the cohesion and combat effectiveness of the team. It was incorporated into the Fourth Column of the Red Fourth Army, participated in the anti-encirclement and suppression battle, and experienced the baptism of war. In October 1934, the Central Red Army was forced to evacuate the Soviet area and began the Long March, but the Independent Battalion was ordered to stay in the Soviet area and persist in three years of arduous guerrilla warfare. The team was tempered into steel in the desperate situation of three years of guerrilla warfare, and forged the military soul, and finally grew into a red iron army that obeyed the party's command, had firm beliefs, and was brave and fearless.
