《资治通鉴·唐纪·唐纪七十一》
黄巢的骁将孟楷既已攻下蔡州，便调动军队去打陈州，率军驻扎在项城；赵先是向孟楷做出势单力薄的样子，乘他没有准备，发动突然袭击，孟楷的人马几乎全被斩杀擒获，本人也被活捉处斩。
孟楷既下蔡州，移兵击陈，军于项城。犨先示之弱，伺其无备，袭击之，杀获殆尽，生擒楷，斩之。
Huang Chao's brave general Meng Kai had already captured Cai Prefecture, so he mobilized his troops to attack Chen Prefecture and led his troops to station in Xiangcheng; At first, Zhao pretended to be weak to Meng Kai, so he took advantage of his unpreparedness and launched a surprise attack, almost all of Meng Kai's men were killed or captured, and he was also captured alive and executed.
