The Red Turbans went on to seize Seogyeong (Pyongyang), Goryeo's western capital. In early 1360 Goryeo forces counterattacked, retook the city and drove the invaders back across the Yalu with heavy losses.

In the winter of 1359 about 40,000 Red Turbans, pushed out of northern China by Yuan forces, crossed the frozen Yalu River into Goryeo, took Uiju and went on to capture Jeongju and Inju.
