赵延寿的亲兵有投降的人说： 契丹主归回到虎北口，听说晋兵袭取泰州，又带领兵众向南进军，约有八万多骑兵，预计明晚应当来到，要赶快作准备。 
赵延寿部曲有降者言： 契丹主还至虎北口，闻晋取泰州，复拥众南向，约八万馀骑，计来夕当至，宜速为备。 
Zhao Yanshou's personal soldiers who surrendered said: When the Khitan master returned to Hubei Pass, he heard that the Jin army attacked Taizhou, and he led his army to the south, with an estimated number of about 80,000 horsemen, and should arrive tomorrow night. Get ready.
