In communicating with Mr. Gladstone on July 23, 1846, Grey described his military operations, which were designed to check a company of some two hundred rebels who, he had reason to believe, were marching from Whanganui to join Te Rangihaeata. He landed at Waikanae, Otaki, and Ohau, where he had a conference with the friendly chiefs. He proceeded to say: "The whole of the chiefs with whom I had interviews declared that these disturbances were to be entirely attributed to the intrigues of Te Rauparaha." How much his mind was influenced by the opinions of the chiefs may be judged by the fact that on the following day he launched his successful stroke, but how little he had weighed the value of their testimony may also be inferred from the circumstance that a year later he wrote a despatch to Mr. Gladstone's successor at the Colonial Office, in which he was forced to admit that after retaining Te Rauparaha in captivity for ten months his difficulties in deciding how to dispose of him were enhanced by the fact that all his "efforts made to secure the evidence of Pohi[181] failed, consequently it was not possible to prove Te Rauparaha's guilt in a court of law."
It is strange, if so many chiefs knew that the brain of Te Rauparaha was forging the balls which Rangihaeata was firing, that none were able to testify to the fact in an established court of law, and, travesty upon British justice though it may seem, it is nevertheless a fact that the man who had relied upon the Treaty of Waitangi to secure him his rights and liberties was detained a prisoner without formal charge and without the chance of a trial until it was thought possible to prove his guilt. How far Te Rauparaha's seizure and continued detention were a palliation to the wounded feelings of the European settlers it is difficult to pronounce, but it is not in the least unlikely that the Governor paid some regard to the popular effect of the step, even if he totally ignored its judicial aspect. In all probability Te Rauparaha was at this time the best-hated man in New Zealand. The memory of the massacre at the Wairau had not yet died out, and there were many who, misunderstanding that fatal event, could not look upon the chief whose name had been so tragically associated with it in any other light than as a social and moral outcast. To this not inconsiderable section of the community imprisonment was much too good for Te Rauparaha, but it was preferable to the negative attitude of Governor Fitzroy, and Grey, no doubt, counted upon standing well with these extremists by the initiation of a policy in which there was a touch of retribution, however barren it might be of justice.
With the European population, then, the kidnapping of the Ngati-Toa leader was, on the whole, a popular move, and with a number of the natives it was hailed as an act of retribution, long delayed, but nevertheless a judgment at last. Upon his own people the effect was different. They were stunned by the swiftness of the blow and confounded by its audacity. Here in a twinkling the very eye had been plucked out of their head, the heart torn from their body, and that, too, at a time when they had no quarrel with the Government, and by a man whom they had been wont to regard as their friend. Their first impulse was to fly to arms. To attack Wellington, to sweep the pakeha into the sea, to avenge the wrongs of Te Rauparaha, was the cry. Te Rangihaeata called his own followers about him and sent out his appeals to the northern tribes: "Friends and children, come and revenge the injuries of Te Rauparaha, because Te Rauparaha is the eye of the faith of all men. Make haste hither in the days of December." But his design for the extermination of the Europeans was doomed to be frustrated. His own particular faithfuls were few in number, and the one great chief, Te Heuheu, to whom he might have looked for encouragement in such an emergency, was dead, buried beneath a huge landslide which had overwhelmed his village on the shores of Lake Taupo. Of others with whom he had been accustomed to co-operate in the days gone by, some were espousing the cause of the enemy, and some, having embraced the Christian faith, had grown weary of incessant war. Their reply, which was something in the nature of a rebuke, betokened that they had realised the futility of opposing the further progress of the pakeha. "How can you dry up the sea? That is why we say, finish fighting with the European." Such was their answer to his summons to arms, and Rangihaeata was left to fall back upon his small band of war-worn desperadoes to carry on a struggle which was hopeless from the first.[182]
Abandoned to his own resources, he applied himself to his duties of leader with the energy of despair. Realising that his position at Pahautanui was no longer tenable, as its swamps and shallows were no protection against the artillery which he knew was collected at Porirua, he withdrew his forces into the deeply wooded Horokiwi Valley. Through this forest defile, tangled and matted by an almost impenetrable undergrowth, he was pursued by a force of 1,000 men, composed of militia and native allies, under Major Last. Te Rangihaeata's generalship proved equal to the peculiar circumstances in which he found himself, and his genius for war won for him the warmest encomiums from British officers, who have generously expressed their admiration for the skill with which the chief conducted his retreat. Into the density of the wooded valley he led his pursuers, enticing them by a simulated resistance, but abandoning his camps as soon as they pressed too closely upon him. In one of these semi-fortified resting-places the British soldiers discovered the bugle which had been taken from the boy Allen when he was struck down at the fatal fight at Boulcott's Farm.
At length, retreat being no longer possible, the rebel chief turned at bay and fought his pursuers at a point near the head of the valley. His decision to throw down the gage of battle here was not the result of accident or impulse, but was due to deliberate calculation. The position was admirably chosen, and he held the enemy in check long enough to enable him to fortify it effectively. He threw a rough breastwork of tree-trunks across the narrow neck of a spur springing from a densely wooded hill, the approach to which was flanked by steep ravines, leaving so narrow a ridge that it could only be passed abreast by a very limited force of men. This wooden rampart, which presented so imposing a front to an enemy, was liberally perforated with loopholes, through which the defenders were able to concentrate their fire with deadly effect upon any approaching force. This arrangement, combined with the inaccessible nature of the ground, made its seizure by storm practically impossible. Nevertheless, an attack was determined upon, and on the morning of August 6, 1846, fire was opened upon the position, but with no other visible result than that Ensign Blackburn[183] and two privates were killed and nine others wounded. On the following day the assault, which had been so inauspiciously commenced, was suspended, for Major Last had now seen enough to convince him that some projectile more searching than bullets was necessary to dislodge the defenders from their stronghold. He accordingly sent to Porirua and procured two small mortars, which, after infinite labour spent in dragging them into position, were discovered to be absolutely worthless for purposes of attack, for the high forest trees made accurate gunnery impossible. Seeing his troops in a deplorable condition, even after this short bush campaign, and hopeless of driving Rangihaeata out, except at an enormous sacrifice of human life, Major Last decided to withdraw the regular troops and leave the friendly natives, under Puaha, to watch and wait for hunger to work its effects upon the stubborn garrison. A few days sufficed for this. On the 13th the allies were surprised by a hail of lead suddenly raining down upon their lines. No sooner had they sprung to arms than they saw that the enemy was afoot, the volley which they had fired being the signal for retreat. Immediately the real nature of the movement was ascertained, Puaha and his loyalists rushed forward over the fallen trees and broken ground, and reached the breastwork only in time to see the last of the defenders escape by the thickly veiled forest track, where they were swallowed up by the bush and lost to human view.
Hunger and cold had done their work, for there were no signs of food supplies inside the camp except some edible fern. Nor did the escape of the defenders to the open avail them much, for they were so harried by the followers of Puaha as they fled along the snow-covered mountain ridge that the opportunities for procuring food were few and uncertain. Some made their perilous way to the coast, in the secret hope of finding food and shelter amongst their friends in the pas, but these were for the most part found by the vigilant Wiremu Kingi, and either driven back into the mountain fastnesses or promptly secured as prisoners of war.[184] Deeming himself fortunate to have so far evaded death or capture, Te Rangihaeata retreated northwards with his famished adherents until he reached the lowlands of the Manawatu. There, beaten though still defiant, he retired to a pa built in the midst of the swamps and marshes of Poroutawhao, where he laid down his arms and, sullenly drawing his mat about him, prepared to watch the irresistible march of the pakeha, though refusing to acknowledge defeat at his hands. "I am finished," he wrote to the Governor, "but do not suppose that you conquered me. No; it was these my own relatives and friends, Rangitake and others. It was by them I was overcome, and not by you, O Governor."[185]
A new cause for anxiety, in the outbreak of hostilities at Whanganui, now diverted Grey's attention momentarily from the fugitive chief, who improved the respite thus given by refraining from any act of violence. Although no formal peace was declared, Grey wisely decided not to precipitate further trouble by following him into the marshes of Poroutawhao. True, on the very day (April 18, 1847) that the news of the outbreak at Whanganui reached Wellington, the chief made a sensational descent upon Kapiti. In the grey of the early morning a whaler named Brown was awakened by a sound at the door of his hut, and, as he raised himself on his elbow, he saw the tall form of Rangihaeata enter the room with a tomahawk in his hand. The whaler not unnaturally thought he had come to take his life, and, in his subsequent narration of the incident, he indulged in some heroics, telling how he had challenged the chief to slay him on the spot. But Rangihaeata was not in search of a defenceless whaler's blood. He had come to demand some powder which was rightly his, and which he had left there for safe keeping. When he had secured his property, he went harmlessly away, after shaking hands in the most friendly manner with the frightened seaman. Some of his followers, however, were not quite so scrupulous; and, in searching the hut for the powder, they had appropriated a bundle of bank notes and some sovereigns, and secreted them about their persons until they returned to the pa. Here Rangihaeata discovered the theft, and immediately sent back the plunder to the Governor, accompanied by a characteristic note, in which he made it clear that, however much he might be in opposition to the Government, he had no desire to be esteemed a common thief.
With Rangihaeata beaten out of the field, we may now return to Te Rauparaha, whom we left in the hands of his captors. To ensure his greater security, he was, immediately upon the arrival of the Driver at Wellington, transferred to H.M.S. Calliope,[186] where he was placed under the watchful eye of Captain Stanley, for whom, we are told, he afterwards acquired a high regard. On board this ship he was detained with some show of liberty for upwards of ten months, visiting the principal ports of northern and central New Zealand, as the duties of the station demanded the presence of the vessel. During all this period no attempt was made to bring him to trial, though no pains were spared by the Governor to secure the evidence which would ensure his conviction. In a despatch written to the Colonial Office on December 1, 1846, Grey endeavoured to explain his position and justify his halting attitude, but, in the trenchant words of one of his critics, his was a justification which itself required to be justified:—
"A number of designing Europeans, who are annoyed at my interfering with their illegal purchases of land, have thought it proper to agitate the question of the justice and propriety of my arresting Te Rauparaha. Some most improper publications have already appeared, and I regret to state that I find a great effect is being produced upon the minds of the native chiefs. The difficulty of my position is that I am not yet quite satisfied whether or not it will be expedient or necessary to bring the old man to trial. In fact, I am rather anxious to avoid doing so, and I fear that, were I to make public the various crimes for which he has been seized by the Government, and the proofs of his guilt upon which the Government justify his detention, a large portion of the European population would be so exasperated against him that it would be difficult for the Government to avoid bringing him to trial; and, if I were compelled to adopt this step from having made known the charges against him, I should probably be accused of having ungenerously prejudiced the public against him previously to his being brought to trial."
The only impression which the unbiassed student can derive from a perusal of this specious reasoning is that the Governor, in seeking to excuse himself for an unjustifiable action, has in reality delivered his own condemnation for a grave breach of trust. If the "various crimes" of which the chief was suspected were as defined as the Governor implies they were, and if "the proofs of his guilt upon which the Government justified his detention" were clear and unimpeachable, obviously then it was his bounden duty to the Colony and to Te Rauparaha that the chief should be brought to trial at the earliest possible moment. But the real fact was that the offences of Te Rauparaha were as imaginary as the proofs of his guilt were mythical, and he was kept captive on a ship of war while the Governor was diligently endeavouring to find Pohi, who was supposed to be possessed of important secrets, or was sedulously filling in the missing links in the chain of evidence which he hoped would establish the fact that certain messengers, who were known to have carried information to Rangihaeata, were indeed sent by Te Rauparaha.
