History of Jin
The "History of Jin", a document written from the perspective of the Jin, reports Jin casualties between one "meng'an" ( Jurchen unit of a thousand soldiers) and a hundred men, and two "meng'an" and two hundred men. The "History of Song" reports Jin casualties numbering four thousand soldiers and two commanders of "wanhu" (万户 ten thousand men) rank. An account of the battle by a different Song source holds that 24,000 Jin soldiers died and that 500 combatants and five "meng-an" were taken as prisoners. A more conservative Song source estimates that the Jin only had 500 soldiers and 20 ships at Caishi.
