In early 1935, the 4th frontal division of the Chinese Red Army carried out a campaign which sought to break the Sichuan clique's "Tumen Blockade" and emerged victorious, entering into Mao County.

[1][2] In June, the Central Red Army led by Mao Zedong, Zhou Enlai, Zhang Wentian, and others entered into Xiaojin County, Sichuan along with the 4th frontal division.

At the time, the 4th division was about 80,000 strong while the Central Red Army had a meager 10,000, its numbers severely depleted from the previous phase of the ongoing Long March.

Mid-October, through appeasement of the local populace, the Red Army under Guotao managed to build up a well sized base in Jinchuan County, and the Northwest Federation was once again established, this time with Shao Shiping as chairman.

[3] Later, the established Jinchuan Provincial Party Committee was created along with both the Geledesha Republic and Central Tibetan Autonomous Government in Xikang.
