Wihwado Retreat
The Wihwado Retreat, or Turning back the army from Wihwa Island (Korean: 위화도 회군; Hanja: 威化島 回軍) refers to the 1388 episode in which General Yi Sŏng-gye of the Goryeo dynasty was ordered to march north with his army and invade the Liaodong Peninsula (northeast China, which was under the control of the Ming dynasty), but instead decided to turn back to Kaesong and stage a coup d'état.가 General Yi Sŏng-gye had gained power and respect during the late 1370s and early 1380s by pushing Mongol remnants off the Korean Peninsula and also by repelling well-organized Japanese pirates in a series of successful engagements. He was also credited with routing the Red Turbans when they made their move into the Korean Peninsula as part of their rebellion against the Yuan dynasty.
