Ma Hongbin
Zhang's remaining troops of 21,800 were later annihilated in 1936 by the superior force of more than 100,000 combined troops of warlords Ma Bufang, Ma Hongbin and Ma Zhongying during efforts to cross the Yellow River and conquer Ma's territory. Zhang lost the power and influence to be able to challenge Mao and had to accept his failure as a result of the disaster which only left him 427 surviving troops from the original 21,800.
