As it was clear that, now the Kaffirs had broken into open war, it would be unsafe in the extreme with the force under him to endeavour to penetrate further, Colonel Mackinnon ordered the column to retire. The gorge was thoroughly searched by infantry before the movement began, and it was not until they had found it was completely deserted by the enemy that the column moved back. They reached camp in the evening, and the Governor, upon hearing what had taken place, immediately proclaimed martial law, and ordered a strict inquiry to be made into the conduct of the Kaffir police. In the morning, however, the encampment of the corps was found deserted, three hundred and eighty-five men, taking with them their wives, cattle, and equipments, having deserted to the enemy during the night. Two strong patrols were sent out to carry the news to the commanders of the other two columns, and to examine the state of the country. They came upon a sight that enraged the troops, even more than the attack upon themselves. A party of the 45th Regiment, consisting of a sergeant and fourteen privates, escorting waggons from Fort White to King Williamstown, had been suddenly attacked by the Kaffirs, who had murdered the whole party. Ronald Mervyn did not hear of this unprovoked atrocity at the time. At daybreak, six detachments--drawn from the Cape Mounted Rifles, and each composed of six men and a non-commissioned officer--were ordered to start at once to various settlements on the border, to warn the colonists of the outbreak of war. Ronald was placed in the command of one of these detachments, and was chosen to lead that which was to warn the settlers on the Kabousie River, as he was acquainted with the country there. It was hoped that these detachments would arrive in time, for it was supposed that the attack on the column had been an isolated affair, the work of the tribe in the immediate neighbourhood. Circumstances proved, however, that that action was only a part of a preconcerted plan, for on the following day, which happened to be Christmas, a simultaneous attack was made upon almost all the border settlements.
