The situation in the Long March after the Red Fourth Army joined forces.
On June 2nd, 1935, the Red Army 1 vanguard troops joined forces with the Red Army on the way to Davy. The westward advance troops of the Red Fourth Front Army conquered Mao Gong on June 8, 1935. Then, I went to Davy Town, southeast of Maogong. On June 12, the Red Army 1 vanguard troops joined forces with the Red Fourth Army on the way to Davy. 18, the Central Committee of the Communist Party of China, China Central Military Commission and Red Army 1 arrived in Maogong. On the evening of 2 1, the Red Army Corps 1 and the Red Fourth Army Corps held a get-together to celebrate the reunion. In order to develop towards the Sichuan-Gansu border and cooperate with the Central Red Army's operations in Sichuan, Guizhou and Yunnan, the Red Fourth Front Army launched the campaign of crossing the Jialing River at the end of March. After fierce fighting, we achieved a great victory in successfully crossing the Jialing River. As a result, the Red Fourth Front Army disrupted the enemy's plan of "suppressing the alliance between Sichuan and Shaanxi", took control of a vast new area two or three hundred miles west of Jialing River, and its strength grew to more than 80,000 people, forming an extremely favorable situation. However, Zhang decided to abandon the Sichuan-Shaanxi base area and move the troops, local armed forces and all rear organs that had stayed in the base area to the west of Jialing River. He took this action because he made a pessimistic estimate of the Sichuan-Shaanxi base area and the whole revolutionary situation. He didn't see the advantages of adhering to the Sichuan-Shaanxi base area and its great role in cooperating with the Central Red Army. He believes that Chiang Kai-shek's own troops chasing the Central Red Army will soon enter Sichuan, and the Red Army will be overwhelmed, so it is better to take the initiative to retreat. Zhang's right-wing thought will inevitably lead to serious differences with the central government in the direction of strategic action after the Red First Army and the Red Fourth Army meet.
