Fang Zhimin and his deputy, Xun Weizhou, were first to break through Kuomintang lines in June, followed by Xiao Ke in August. These movements surprised the Kuomintang, who were numerically superior to the communists at the time and did not expect an attack on their fortified perimeter. However, things did not turn out as the communists had hoped: Fang Zhimin's force was crushed after its initial success, and with Xun Weizhou killed in action, nearly every commander in this force was wounded and captured alive, including Fang Zhimin himself, and all were executed later by the nationalists.
