See it on the Korean History map →What happened
At Hwangsanbeol (황산벌), a plain near today's Nonsan, Gyebaek blocked the Silla army marching on Baekje's capital. By the Samguk sagi's account he first killed his own family so they would not be enslaved. His outnumbered troops won four clashes. Silla's morale turned after Gwanchang, a 16-year-old hwarang, charged, was captured and released, charged again, and was beheaded. Silla then attacked and overwhelmed the Baekje force; Gyebaek died fighting.
Why it matters
It opened the road to Sabi and became a lasting Korean story of loyalty, honoring both sides: Gyebaek for Baekje, Gwanchang for Silla.
How we know
The Samguk sagi's biographies of Gyebaek and Gwanchang; the general area near Nonsan is known, though no battlefield archaeology confirms the details.
Still debated
The troop numbers and dramatic episodes may be shaped by later storytelling; the exact battlefield site is uncertain.

▸Kim Yu-sin won Battle of HwangsanbeolWell documented
The connection
Kim Yu-sin led 50,000 Silla troops toward Sabi to meet the Tang army. Blocked at Hwangsanbeol and beaten in four early clashes, his fellow generals sent their own young hwarang sons, Bangul and Gwanchang, to charge. Their sacrifice rallied the army, which broke Gyebaek's line.
When and how
660, on the Hwangsanbeol plain near today's Nonsan, South Chungcheong, against Baekje's general Gyebaek.
How we know
The Samguk sagi's biographies of Kim Yu-sin, Gyebaek and Gwanchang tell the battle in consistent detail.
Debates and open questions
Silla reached the Tang camp late, and Su Dingfang nearly executed a Silla officer; how close the alliance came to breaking is unclear.
▸Battle of Hwangsanbeol sealed Fall of BaekjeWell documented
The connection
Gyebaek's army was Baekje's last field force between Silla and the capital. Once it was gone, Silla's army joined Tang outside Sabi within days, and the city fell. Baekje had no other army close enough to save it.
When and how
Seventh lunar month of 660; Sabi fell days after Hwangsanbeol, and King Uija surrendered about a week later.
How we know
The Samguk sagi's dated entries show the quick sequence from battle to surrender.
Debates and open questions
Some historians argue Baekje's court was already divided and weakened, so it might have fallen even without this defeat.
