In the summer of 1936, the Second Legion, the Sixth Legion and the Thirty-Second Army formed a new group army. It was named the Second Red Army and He Long was tasked with being its commander. The Second Red Army and Fourth Red Army arrived in north Shaanxi Province in the autumn of 1936. Around the same time, roughly 21,000 soldiers from the Fourth Red Army attacked Gansu Province, wanting to find a way to the Soviet Union. By the end of 1936, they were defeated by the Nationalist forces' General Ma Bufang, with more than 6,000 soldiers being captured. Only Xu Xiangqian and other senior officers survived. Because of this great failure, the Fourth Red Army's Commander in Chief Zhang Guotao was stripped of his military power.
