Crawfurd was sent on an envoy mission to Burma in 1826, by Hastings's successor Lord Amherst, in the aftermath of the First Anglo-Burmese War. It was to be his last political service for the East India Company. The party included Adoniram Judson as interpreter and Nathaniel Wallich as botanist. Crawfurd's journey to Ava up the River Irrawaddy was by paddle steamer, the Diana. The mission was a success with Crawfurd negotiating a valuable trade treaty. On the return, the expedition made significant natural history discoveries.
