Boseong

Posŏng lies among the hills and river valleys of southern Chŏlla, near the peninsula's southern coast. In 1441 several districts formerly attached to it were transferred to Hŭngyang, reducing the county's territory. During the renewed Japanese invasion of 1597, Admiral Yi Sunsin worked to rebuild the shattered Korean navy. The Choyang granary supplied provisions, while warships were provided at Hoeryŏngp'o.
