On 22 January 1879 after the disaster of the Battle of Isandhlwana, South Africa, Lieutenant Melvill made efforts to save the Queen's Colour of his regiment. He and Nevill Josiah Aylmer Coghill were pursued by Zulu warriors and after experiencing great difficulty in crossing the swollen Buffalo River, during which time the Colour was lost and carried downstream, the two men were overtaken by the enemy and following a short struggle both were killed. The Colour was retrieved from the river ten days later.
