Authorised on 22nd March 1870 for service in the Bhootan campaign from December 1864 - February 1866.
The Indian Government had decided to take action against bhootan primarily because of the treatment of Hon.Ashley Eden, head of a mission into Bhootan and also because of the continual raids by the Bhootanese into British Territory.
Two Victoria Crosses were awarded during this campaign, Lieut. James Dundas, Royal Bengal Engineers and Major William Trevor also of the Royal Bengal Engineers.
