《资治通鉴·唐纪·唐纪六十六》
高骈派五千人先渡海进发，与李维周约好，让他发兵前去支援；高骈既已出发，李维周接管其余留在海门的军队，却不调一兵一卒继后跟进。
骈以五千人先济，约维周发兵应援。骈既行，维周拥馀众，不发一卒以继之。
Gao Pian sent 5,000 men to cross the sea first to advance, and made an agreement with Li Weizhou for him to dispatch his forces to aid them. Gao Pian set out, and Li Weizhou took over the remaining army at Haimen, but did not send a single soldier to follow after Gao Pian.
