Qing Vietnam Campaign

1785

Qianlong sent a Qing army into Vietnam to restore the Le dynasty against the Tay Son brothers. The Qing entered Hanoi; the Tay Son leader Nguyen Hue counterattacked on the Tet holiday, routing them at the battle of Ngoc Hoi. Humiliated, the Qing withdrew. It was counted as one of the 'Ten Great Campaigns' anyway.
