A similar panel is illustrated by D. Clifford, Chinese Carved Lacquer, London, 1992, p.125, pl.99, where the author notes that the panel shows the campaign of General Agui, sent in 1771 to suppress an uprising in the mountains of Sichuan. Agui was appointed to the Grand Council in 1763, and his family raised from the Manchu plain blue banner rank to the plain white banner rank. In 1764 he was appointed acting Governer General of Sichuan and despatched there to investigate reports of disturbances. There was an uprising in West Sichuan in 1771 and the powerful chieftains in this mountianous region defended their strategic passes with massive stone forts, which took Agui five years to conquer, and the last chieftains surrendered in 1776. The victorious was greeted by the Qianlong emperor personally upon his return to Beijing.
