《旧唐书·列传·卷十七》
萧铣认为当时正值秋汛时期，江水泛滥暴涨，三峡道路险阻，断言李靖不可能进兵，于是令军队休息不加防备。
铣以时属秋潦，江水泛涨，三峡路险，必谓靖不能进，遂休兵不设备。
Xiao Xi believed that it was the autumn flood season, when the river water was flooding and surging, and the Three Gorges were treacherous. He asserted that Li Jing would not be able to advance, so he ordered his troops to rest and not to be on guard.
