Nga Lạc
Nga Lạc lay in the wooded uplands of western Thanh Hóa, in the country around Ngọc Lặc. Its hills and valleys formed part of the homeland of Lê Lợi and the Lam Sơn rising. After the revolt began in 1418, its forces endured difficult years among the mountains. In 1419 they captured the Ming post at Nga Lạc, one of the early actions in the long campaign that restored Đại Việt.
