淝河
In November 383 the Former Qin troops set up camp west of the Fei River. The Jin forces stopped east of the Fei and could not advance. Xie Xuan sent a messenger to Fu Rong, suggesting that the Former Qin forces retreat slightly west to allow Jin troops to cross the Fei River so that the two armies could engage. Most Former Qin generals opposed that plan, since maneuvering such a large army in that manner was too complicated for the benefits that might be obtained, especially with so many poorly trained troops. Fu Jiān overruled them, however, planning to attack the Jin army as it was crossing the river to seize a tactical advantage, as the Jin would be split in two. Fu Rong agreed, and ordered a retreat.
