The Nerbudda incident (Chinese: 吶爾不噠號事件) was the execution of 197 personnel of the British transport ship Nerbudda and brig Ann in Taiwan on 10 August 1842 during the First Opium War. An additional 87 prisoners died from ill treatment in captivity. In September 1841, the Nerbudda became shipwrecked off northern Taiwan near Keelung. In March 1842, the Ann became shipwrecked at Da'an harbour. Survivors from both ships—primarily Indian camp followers and lascars—were captured and marched south to the capital of Taiwan Prefecture, where they were imprisoned before being beheaded. Out of the nearly 300 castaways who landed or attempted to land in Taiwan, only 11 survived captivity and execution. The Daoguang Emperor ordered the execution on 14 May 1842, after the Chinese defeat in Zhejiang.
