When the war rolled almost to his door, Mr. Voelkner judged it wise to take his wife to Auckland; but he himself came backwards and forwards to the disturbed district. In February, during the missionary's absence, Opotiki was visited by two prophets, Patara of the Taranaki, and Kereopa of the Ngati-Porou, with a number of Taranaki Hauhau at their heels. The Whakatohea were ripe for any mischief as it was, and readily embraced the new creed, their conversion being accompanied by much revolting ritual.
Feeling already ran high against the absent missionary, the Whakatohea having allowed themselves to be persuaded that he was hostile to the Maori cause, and desirous of breaking up the tribes.
Patara, who cannot have been all bad, wrote warning Mr. Voelkner not to return to Opotiki; but the missionary unfortunately arrived on the very next day, in a schooner, accompanied by a colleague, the Rev. Mr. Grace.
Mr. Voelkner was at once informed that he was to be killed, but refused to believe that the people among whom he had laboured would prove false to his teaching. A few hearts were softened towards him; but Kereopa would brook neither denial nor delay, and on the following day took out Mr. Voelkner and hanged him upon a willow-tree, shooting him through the body before life was extinct. The fierce Hauhau then swallowed the eyes and drank the blood of his victim.
Mr. Grace was in great danger; for the fanatics, having literally tasted blood, clamoured for more. For fourteen days the unfortunate man endured agonies of suspense, and his relief must have been intense when H.M.S. Eclipse appeared outside the bar. Owing to Patara's influence, the missionary was free to wander within the boundaries of the Opotiki plain, and this circumstance, along with the absence of most of the Hauhau at a feast, helped to effect his escape.
As he was watching the crew of the schooner shifting cargo, one of the sailors murmured, "Go down to the point, and we will get you off." Mr. Grace obeyed with assumed carelessness, and a moment later was in the schooner's boat, speeding towards the Eclipse. Two of the boats from the man-of-war dashed up the river immediately afterwards and towed the schooner over the bar, when no time was lost in leaving Opotiki of tragic memory.
Three months later the ruffians at Opotiki again drenched themselves with blood, murdering the crew of a cutter and Mr. Fulloon, a Government agent, who was on board as a passenger. Mr. Fulloon was a Maori of distinguished lineage on his mother's side; but, nevertheless, at the order of Horomona, the Hauhau, one Kirimangu shot the poor man while asleep with his own revolver. Kirimangu was captured and hanged; but Kereopa managed to evade his doom for seven years, when justice, long disappointed, made sure of him.
Kereopa and his Hauhau were not allowed to pursue their wicked way unchecked. As soon as they could be spared from Whanganui, five hundred men of the Military Settlers, the Bush Rangers, the Native Contingent, and the Whanganui Yeomen Cavalry were ordered to Opotiki, under Majors Brassey and McDonnell, the latter of whom could effect things with the Native Contingent which few other officers could bring about. Not only was McDonnell familiar with the Maori, but he knew their language and their country, so that he met them on their own ground in their own manner. He was brave to rashness, but this was hardly a fault in Maori eyes.
The column accomplished some good, and captured Moko Moko and Hakaraia, who were immediately informed that they could not be treated as prisoners of war, but would be tried for the murder of Mr. Voelkner, in which they had been concerned. After a good deal of successful skirmishing, the force returned to Whanganui, their chief casualty occurring on the way.
The mate of the transport loaded a small cannon for the amusement of some friendlies, but the gun would not "go off," whereupon the searchers after entertainment peeped inquiringly down the muzzle. The humoursome cannon chose that particular moment to indulge in a belated explosion, which fortunately did no more than wound the mate and two of the Maori. The outcome of the accident was the refusal of the Native Contingent to proceed after so evil an omen.
