Robert Bruce (1789–1824)[1] was a Scottish arms trader and mercenary soldier on the north-east frontier of India.
This was doubted, however, by Edward Albert Gait, who mentioned his brother, Charles Alexander Bruce, and his 1809 voyage to India.
[5] According to the Dictionary of Indian Biography, Charles Alexander Bruce was born in Assam, at Jorhat.
He then agreed to support Chandrakanta Singha, against the Burmese forces of the Konbaung dynasty, who was regrouping in the Goalpara district.
Bruce learned from Maniram Dewan that the Singpho people grew tea, which was then not generally known.
