He Long
The Second Front Army, under He Long and Ren Bishi, and Xiao Ke's Sixth Front Army linked up with the Fourth Front Army in June 1936. Again dividing their forces, He Long took the Second on a northward line toward Gansu while Zhang led his forces somewhat west of that line. The result was that Zhang’s Fourth Front Army was battered by Nationalist and warlord troops, and arrived in Yenan in poor shape in October 1936. Zhang was forced to submit to Mao’s leadership.
