Robinson was replaced as Governor of Fiji in June 1875 by Sir Arthur Hamilton Gordon. Gordon was immediately faced with an insurgency of the Qalimari and Kai Colo people. In early 1875, colonial administrator Edgar Leopold Layard had met with thousands of highland clans at Navuso to formalise their subjugation to British rule and Christianity. Layard and his delegation managed to spread the measles epidemic to the highlanders, causing mass deaths in this population. As a result, anger at the British colonists flared throughout the region, and a widespread uprising quickly took hold. Villages along the Sigatoka River and in the highlands above this area refused British control, and Gordon was tasked with quashing this rebellion.
