Red Turban Invasions
The Red Turbans, Han Chinese rebels against the late Yuan, invaded Goryeo twice; in the second invasion Gaegyeong fell and King Gongmin fled to Bokju (Andong).
In the twelfth month of 1359 some 40,000 Red Turbans crossed the Yalu and took Seogyeong, but were driven out the next year. In 1361 over 100,000 returned and captured Gaegyeong, and Gongmin fled to Bokju (Andong).
In the first month of 1362 an army of 200,000 under Jeong Se-un, An U, Yi Bang-sil and Kim Deuk-bae retook the capital, with Choe Yeong and Yi Seong-gye distinguishing themselves. The war devastated the country, and the generals who fought the Red Turbans and pirates emerged as a new force.
