The Battle of Huangtiandang (simplified Chinese: 黄天荡之战; traditional Chinese: 黃天蕩之戰) was an early battle in the Jin–Song Wars. From 1129, the Jin forces led by Wuzhu marched southward, successively conquering several important cities north of the Yangtze River. Wuzhu sent forces to chase after the Song court, but was ambushed by Song forces led by Han Shizhong and Liang Hongyu at Huangtiandang, northeast of today's Nanjing city. The Jin army was trapped there for 48 days, but finally was able to retreat on the suggestion of a Song resident.
