Zhang Peiyuan, a Han Chinese General, who commanded Han Chinese troops in Ili, conducted negotiations with Ma Zhongying and planned to join him on the attack on Urumchi in January 1934. Initially Zhang seized the road between Tacheng and Ürümqi, but decided to return to Ghulja after receiving of message of capturing the city by Russian "Altai Volunteer Army", actually Soviet troops entered the city. Upon approaching Ghulja he was surrounded on mountain road, his troops were partly annihilated, partly fled to Muzart Pass on Tianshan Mountains and through it to Southern Xinjiang near Aksu. Zhang Peiyuan himself committed suicide. Ma Zhongying attacked Urumchi as was planned, taking Sheng completely by surprise, hiddenly approaching the city from the hills on the west and first capturing the telegraph station and aerodrom, then started besieging the city, completely isolating it from suburbs. But the fact, that in the crucial moment of besieging of Urumchi Ma Zhongying didn't receive the promised help from Zhang Peiyuan's Ili Army, was the reason of Ma's failure to capture the city in the first weeks of attack, nevertheless its fall was imminent and just a matter of time without intervention of Soviet troops. The battle for Urumchi was decisive for the whole Ma Zhongying's campaign in Xinjiang and its taking by his forces would lead to recognision of him "The absolute ruler of Xinjiang" by Nanjing Government of China, as was previously secretly promised to him.
