In October 1934, Zhang Wentian participated in the Long March with Mao Zedong and Wang Jiaxiang. Three people communicated many times during the march on the way and formed an alliance against Bo Gu and Li De. On January 15, 1935, the First Red Army occupied Zunyi, Guizhou during the Long March, and held a meeting. At the meeting, Bo Gu took the lead in making a report to discuss the errors of military command during the fifth anti-encirclement campaign, but mainly asserted that the difficulties were unavoidable due to circumstances. Zhou Enlai then made a deputy report, saying that it was the tactical errors made by the military command, and admitted responsibility. It was followed by Zhang Wentian's report opposing the Central Committee's military strategy that solely focused on defense. Then, Mao Zedong made a long speech, pointing out that the cause of serious loss and defeat in the fifth anti-encirclement campaign was due to the military's simple defense line, and this was manifest in the adventurism during the attack, the conservatism during the defense, and conservatism during the sortie. Mao Zedong had planned this outline in advance with Wang Jiaxiang and Zhang Wentian. Immediately, Wang Jiaxiang, Zhu De, Liu Shaoqi expressed agreement. The meeting was held for three days, and the final decision was to dismiss the leadership of Bo Gu, Li De, and Zhou Enlai. Mao Zedong was co-opted onto the standing committee of the CPC Central Committee Political Bureau by military commanders Zhu De and Zhou Enlai, and was also restored to the position as the military commander of the Red Army.
