Gyeon Hwon
In 927, Gyeon Hwon led his army himself and directly attacked the Silla capital of Gyeongju. King Gyeongae was unprepared for this attack, and he chose suicide over capture by the invading army of Hubaekje. Gyeon Hwon then established Kim Bu (who became King Gyeongsun) as the next Silla king. On his way back, he was met by the forces led by Wang Geon, and easily defeated the Goryeo army, killing many of Wang's notable generals and warriors, with Wang barely escaping through the daring self-sacrifice of his general Shin Sung-gyeom and Kim Nak. One year later he took over the city of Jinju from Silla.
