The situation intensified further in early 1873 when the Burns family was killed by a Kai Colo raid in the Ba River area. The Cakobau government deployed 50 King's Troopers to the region under the command of Major Fitzgerald to restore order. The local whites refused their posting, and deployment of another 50 troops under Captain Harding was sent to emphasise the government's authority. To prove the worth of the Native Regiment, this augmented force went into the interior and massacred about 170 Kai Colo people at Na Korowaiwai. Upon returning to the coast, the force was met by the white settlers who still saw the government troops as a threat. A skirmish between the government's troops and the white settlers' brigade was only prevented by the intervention of Captain William Cox Chapman of , who detained the leaders of the locals, forcing the group to disband. The authority of the King's Troops and the Cakobau government to crush the Kai Colo was now total.
