Cho Ton

Cho Ton (趙暾, 1307–1380) was a Goryeo civil official born at Yongjin, a son of Cho Yanggi, the second Ssangsŏng commandant, and uncle of the fourth commandant, Cho Sosaeng. He had submitted to Goryeo under King Ch'ungsuk.

When Goryeo retook Ssangsŏng in 1356, his nephew detained him, but Ton escaped, joined Yu In-u, and with Yi Cha-ch'un opened the gates to the Goryeo army. In 1359 his mission to coax Sosaeng into surrender failed.
