After Pae Chung-son was killed on Jindo Island by Goryeo-Mongolian allied forces at 1271, Kim T'ong-jŏng and a few Sambyeolcho Army escaped Jindo Island and moved to Tamna Island (now Jeju Island). After, he still was opposed to Mongol Yuan dynasty. In 1273, Korean Goryeo government sailed to Tamna and defeated the rebellion with the aid of Mongol forces.^[1] Kim T'ong-jŏng and 70 of his men escaped to Hallasan. The 70 were later captured but not Kim himself who was presumed dead.^[2] It was assumed that he committed suicide, although some tales of him in Jeju tell of he being killed by Kim Pang-gyŏng of Goryeo who later killed Kim's pregnant wife.^[3]

There are two views about Kim T'ong-jŏng. In the Goryeo dynasty, he is perceived as a bad general as he is described at Goryeosa (History of Goryeo) due to stealing and bothering Tamna. On the contrast, the subjects of Tamna recorded that he was treated like hero.
