liu xiu carried out his action, and when he returned to kunyang, he began harassing the sieging xin forces from the outside. wang yi and wang xun, annoyed, led 10,000 men to attack liu xiu and ordered the rest of their troops not to move from their siege locations. once they engaged in battle, however, after minor losses, the other units were hesitant to assist them, and liu xiu killed wang xun in battle. once that happened, the han forces inside kunyang burst out of the city and attacked the other xin units, and the much larger xin forces suffered a total collapse. the soldiers largely deserted and went home, unable to be gathered again. wang yi had to withdraw with only several thousand men back to luoyang. this was a major blow to xin, psychologically; after this point on, there would be no hope for it.
