 Ashina She 'er 's soldiers were organized in five columns . The Tang army bypassed Karasahr and struck at Kucha from the north by moving through the Dzungarian Basin , which was the territory of the Chuyue ( possibly Chigil ) and Chumi , two Turkic tribes allied with the oasis state . The Tang army defeated the Chuyue and Chumi before entering the Tarim Basin , upon which the king of Karasahr fled his capital city and tried to find a defensible position in Kucha 's eastern territories . Ashina She 'er 's forces pursued the Karasahr king , took him captive , and then executed him .
