The Battle of Hwangsanbeol and the Fall of Baekje in 660 AD marks a tragic yet pivotal moment in the history of the Three Kingdoms period on the Korean Peninsula. By the mid-7th century, Baekje, initially strong under King Uija, had begun to suffer from internal strife and political instability. Meanwhile, Silla, under the leadership of Kim Chun-chu (later King Muyeol), forged a powerful alliance with Tang China, driven by its ambition to unify the peninsula. Tang China, eager to expand its influence in East Asia, readily supported Silla's objectives. In 660, a formidable Tang naval force of 130,000, led by General Su Dingfang, landed on Baekje's western coast, while a 50,000-strong Silla army, commanded by General Kim Yu-sin, advanced overland towards the Baekje capital, Sabi. Baekje found itself in a desperate situation, facing a pincer attack. It was at this critical juncture that General Gye Baek, Baekje's last loyal general, emerged. He gathered 5,000 elite "do-or-die" soldiers and resolved to intercept the Silla army at Hwangsanbeol. Famously, before the battle, Gye Baek killed his own family to eliminate any personal attachments, inspiring his troops to fight to the death for Baekje. The Battle of Hwangsanbeol saw Baekje's desperate resistance repeatedly frustrate the Silla forces. Despite being outnumbered ten to one, General Gye Baek and his soldiers fought with unparalleled ferocity. The Silla army, spurred on by acts of bravery such as the sacrifice of Hwarang Gwan Chang, eventually broke through the Baekje lines after numerous fierce engagements. General Gye Baek fought valiantly until his death. With Hwangsanbeol breached, the path to Sabi was open. The Silla forces, joining with the Tang army, captured Sabi. King Uija surrendered, and Baekje, after 678 years of history, ceased to exist. This event, while sparking brief Baekje restoration movements, ultimately paved the way for Silla's unification of the Three Kingdoms, and General Gye Baek remains an enduring symbol of loyalty and sacrifice.
