紅巾軍
The House of Duan, who helped the Mongols against a Red Turban Rebellion attack from Sichuan, also fought against the Ming army. The ruler Duan Gong refused to surrender by writing to Fu Youde, making it clear that Dali could only be a tributary to the Ming. Fu Youde attacked and crushed Duan Gong's realm after a fierce battle. The Duan brothers were taken captive and escorted back to the Ming capital.
