Xiang Han: In Days Gone By

The Prince of Xiang’s army was encamped at Gaixia. His troops were few and their provisions exhausted, while the Han army and the forces of the other lords surrounded them in several layers. At night, he heard the songs of Chu coming from every direction in the Han camp. The Prince of Xiang was greatly alarmed and said, "Has the Han already conquered all of Chu? Why are there so many people of Chu?" Records of the Grand Historian, "The Annals of Xiang Yu"
