Fei River
Traditional Chinese historiography celebrated the battle of Caishi as an important victory for the Song. Caishi was held in the same esteem as the Battle of Fei River in 383, when the Eastern Jin defeated the northern invaders of the Former Qin. It is portrayed as a victory against overwhelming odds, in which 18,000 Song soldiers overcame an army of nearly half a million men. Over the course of the battle, more and more Jin troops deserted in the face of the superior Song navy, thereby decreasing the total Jin force.
