《新唐书·列传·卷十七》
起初，伏威渡过淮河与李子通合兵，后来子通畏忌其才，派出骑兵袭击，伏威身受重伤坠落马下，雄诞背着他逃匿于芦苇泽中，收集散亡士卒，又被隋将来整所败，其众再次溃散。
初，伏威度淮与李子通合，后子通惮其才，袭之，伏威被创堕马，雄诞负逃葭泽中，裒啸散亡，又为隋将来整所窘，众复溃。
Initially, Fuwei crossed the Huai River and joined forces with Li Zitong. Later, Zitong became wary of his talent and sent cavalry to attack him. Fuwei was severely injured and fell from his horse. Xiongdan carried him on his back and escaped into a reed marsh. He rallied the scattered soldiers, but they were defeated again by the Sui general Lai Zheng, and his forces dispersed once more.
