The man who turned his sword away from the enemy — and toward a dynasty

In 1388, General Yi Seong-gye was ordered to march north and attack Ming China. Instead, he turned his army around at Wihwa Island and marched back to the capital. That single decision — known as the Wihwado Retreat — effectively ended the Goryeo dynasty and set the stage for the founding of Joseon in 1392. What makes this moment fascinating is the sheer audacity of it. He was a military commander defying a direct royal order, yet he managed to frame it not as treason, but as saving the nation from a suicidal war. Within four years, he was king. Was Yi Seong-gye a visionary leader who saw the futility of fighting Ming China? Or was he an ambitious general who exploited the situation for personal gain? The truth probably lies somewhere in between — but either way, his gamble reshaped Korean history for the next 500 years.
