Peng was a strong supporter of Mao's rise to power during the January 1935 Zunyi Conference. Peng continued to consolidate the communists' base area after arriving in Shaanxi by campaigning in neighboring Shanxi and Gansu. In April 1937, Peng was named vice commander-in-chief of all Chinese communist forces, outranked only by Zhu De, who was named commander-in-chief. Peng's promotion was supported by Lin Biao, who had been actively supporting Peng for promotions to senior leadership as early as May 1934. In early 1935, Lin responded to widespread discontent within the Red Army over Mao's evasive tactics, which it perceived as unnecessarily exhausting, by publicly proposing for Peng to take overall command of the Red Army, but Mao, who had recently been promoted to the position, attacked Peng and Lin for challenging him and successfully retained his position.
