When it became known that Te Rauparaha had retired to Kapiti, and there seemed less danger of immediate molestation, the Rangitane people again began to collect in force near their old home at Hotuiti. They built a strong _pa_ near the present town of Foxton, and here they were joined by a number of Ngati-Apa chiefs and people from Rangitikei. This proceeding Te Rauparaha regarded as a danger and a menace to his safety; for he had no reason to believe that he enjoyed their friendship, and no means of ascertaining when they might think fit to wreak their vengeance upon him. He therefore decided to take the initiative and attack them. Accordingly, with Rangihaeata and his Ngati-Apa wife Pikinga, he marched his war party up the coast and at once invested the place. The method by which he sought to reduce the _pa_ to submission was a clever stratagem--perfectly honourable, perhaps, according to the Maori code of warfare--but utterly repulsive to civilised ideas; and, to those who judge him by the latter standard, it lowers Te Rauparaha from the high plane of a classic warrior to the level of a cunning and unscrupulous savage. His first act of generalship aimed at separating the two tribes, a step which has been attributed by some to a desire to spare the Ngati-Apa, because of their relationship with Pikinga. Others, however, can see in it nothing but a clever ruse to divide the defending force, so that he might the more easily attack and defeat them singly. He therefore sent Pikinga to the Ngati-Apa chiefs with a request that they would withdraw to their own territory beyond the Rangitikei River. Probably he promised them safe-conduct on their journey; but, if he did, it was of no avail, for they firmly refused to evacuate the Hotuiti _pa_, and doggedly remained where they were. Feigning, then, to abandon his campaign, Te Rauparaha sent to the Rangitane chiefs, inviting them to come to him and negotiate terms of peace.
In view of their past experiences it might have been expected that such a request would be scornfully declined; but after long and anxious debate it was decided--mainly, it is said, on the advice of the Ngati-Apa chiefs--that the leading Rangitane warriors should meet the Ngati-Toa leader and make the best terms possible with him. The result was, of course, the old story: the ruthless slaughter of the confiding ambassadors, who found that Te Rauparaha had come, not with peace, but unrelenting war. Treachery was no more suspected inside the _pa_ than out of it; and while the people were deluded into the belief that the war-clouds had passed away, they were being secretly and silently surrounded. At a given signal the walls were stormed and a bloody massacre followed, from which the Ngati-Toa warriors emerged sated with gruesome triumph. The slain were eaten on the spot, and the prisoners were taken to Waikanae, there to await the returning appetite of their captors.
