With the demand for land high, the white planters started to push into the hilly interior of Viti Levu. This put them into direct confrontation with the Kai Colo, which was a general term to describe the various Fijian clans resident to these inland districts. The Kai Colo were still living a mostly traditional lifestyle, they were not Christianised, and they were not under the rule of Cakobau or the confederacy. In 1867, a travelling missionary named Thomas Baker was killed by Kai Colo in the mountains at the headwaters of the Sigatoka River. The acting British consul, John Bates Thurston, demanded that Cakobau lead a force of Fijians from coastal areas to suppress the Kai Colo. Cakobau eventually led a campaign into the mountains but suffered a humiliating loss with 61 of his fighters being killed. Settlers also came into conflict with the local eastern Kai Colo people called the Wainimala. Thurston called in the Australia Station section of the Royal Navy for assistance. The Navy duly sent Commander Rowley Lambert and  to conduct a punitive mission against the Wainimala. An armed force of 87 men shelled and burnt the village of Deoka, and a skirmish ensued which resulted in the deaths of over 40 Wainimala.
