From 1367 to 1390, according to Chinese and Vietnamese sources, Che Bong Nga, who ruled as king of Champa from 1360 to 1390, had restored Champa.[94] He launched six invasions of Dai Viet during the deadly Champa–Đại Việt War (1367–1390), sacking its capital in 1371, 1377, 1378, and 1383, nearly bringing the Dai Viet to its collapse.[95][96] Che Bong Nga was only stopped in 1390 on a naval battle in which the Vietnamese deployed firearms for the first time, and miraculously killed the king of Champa, ending the devastating war.
