Timeline

1. 1161coastal waters of Jiaoxi and Shijiu Island · Shandong ProvinceWanyan Liang invaded southward on multiple routes; the naval force, led by Su Baoheng and Wanyan Zhengjia, planned to sail south along the coast from the Shandong Peninsula to attack the Southern Song's temporary capital. The Jin forces were mostly northerners unfamiliar with sea routes, and their warships' sails and rigging were mostly made of oiled silk, leaving a weakness for later fire attacks.
2. 1161waters off Tangdao · Yellow SeaLi Bao led over a hundred warships northward; taking advantage of the Jin ships being at anchor and unprepared, he concentrated fire arrows, thunder cannons, and other fire weapons on their sails and rigging, then engaged in close combat. The Jin ships' oiled sails were easily ignited, soldiers leaped into the water, Wanyan Zhengjia was killed, and Su Baoheng fled back; the Jin dynasty's capacity for a sea route offensive was destroyed.
