Han Shizhong
In February, 1130, Wuzhu declared that he had finished the search for Emperor Gaozong, and moved back north along the Jinghang canal, carrying large amounts of gold, silver, treasures and jewels plundered by the troops from all places of Jiangnan. Before leaving, he committed Lin'an, which was a city steeped in history, to the flames, and his troops burnt, killed and looted on their way, which became a calamity for the people in Jiangnan. In March, Wuzhu's army arrived in Zhenjiang. They were blocked by Han Shizhong's troops. The navy led by Han Shizhong had huge and lofty warships which were guarding the estuary, preventing Jin troops from crossing. Jin troops had less and smaller battleships and were not good at battles on water, though they outnumbered their enemies. At the beginning, Jin troops suffered great losses, and Wuzhu still could not cross the river after a stalemate for 48 days. His troops had to penetrate up the river to Jiankang. When they got to Huangtiandang, the troops dug a 15-kilometre canal along the old water channel of the Laoguan River (老鹳河) overnight, which led to the Qinhuai River and finally enabled them to escape back to Jiankang. Since Han Shizhong pursued to Jiankang and blockaded the river with warships, Wuzhu posted a reward for the scheme to destroy the warships to cross the river. A man from Fujian Province gave him a suggestion of shooting flaming arrows into the sails of the warships, which could not move without wind. Wuzhu followed his advice and made flaming arrows that very night. On a still sunny day, Wuzhu carried out the scheme and succeeded. Countless Song soldiers were burnt to death or drowned in the river. Han Shizhong had to abandon his ship and escape back to Zhenjiang with only dozens of his men.
