1288年元朝、安南战争中白藤江桩阵与下游河道考

On the Bai Teng River's Stake in the Yuan-Annan War and the Downstream Channel in 1288

在1288年元越白藤江之战中,陈朝军队布阵用的木桩,是采自安兴森林的格木,长度多在两米左右,形态分为独木桩和"X"形两种,主要布置在争江、抽江和谷湍濑左侧。陈朝军队布置桩阵的时间,应该是当年3月底至4月8号的每天下午。而从当时的白藤海口的沙海地形和元军撤军路线来看,当时白藤下游的河道并非今日的江道,而在今棦江一线。

In the battle of Yuan-Annan war in 1288, the Chen army use the Bai Teng river＇s stake as matrix, and with the help of power of the tides, beat Yuan army successfully. Stakes mainly are cut from Anxing forest, its standard usually around two meters in length, morphology are divided into single piles and ＂X＂ form. The main arrangement locations are Zheng river and Chou river. The troops pile array of time, should be in 1288 at the end of march to April 8 every afternoon. The downstream river channel of 1288 is not in today＇s location,but in Zheng river.
