Cause

The Red Flag Fleet, a powerful Chinese pirate confederation under Ching Shih and her second-in-command Cheung Po Tsai, operated aggressively in the Pearl River Delta region, threatening Portuguese and Chinese maritime trade around Macau and the Humen Strait.

Event

Between September 1809 and January 1810, a Portuguese flotilla based in Macau engaged the Red Flag Fleet in a series of battles within the Humen Strait, known to the Portuguese as the Boca do Tigre. Under the command of José Pinto Alcoforado de Azevedo e Sousa, the Portuguese inflicted multiple defeats on the pirates.

Consequence

Following repeated naval defeats, the Red Flag Fleet surrendered formally in February 1810. Ching Shih subsequently surrendered to the Guangzhou city government in exchange for a general pardon, effectively ending her career as a pirate and dismantling one of the most powerful pirate fleets in Chinese history.
