In April 1831
Fenuapeho, the guardian chief of Taha'a for
Teri'inohora'i, traveled to Bora Bora in a single canoe but was lost on his return. During Tamatoa III's absence serious divisions emerged in the Leeward Islands, provoked by the treachery of several chiefs of
Ra'iātea against their king. These disaffected leaders persuaded the young chief of
Taha'a to detach the island from the authority of Ra'iātea and to attach it to the government of Bora Bora, as it had existed in the time of
Puni and his grandfather
Tapoa I. Tamatoa rejected this transfer of government and sought counsel from the chiefs, who advised reconciliation with
Tapoa, but negotiations proved fruitless as neither side was willing to compromise. Tamatoa then prepared to restore the exiles of Taha'a to their ancestral lands, while Tapoa dispatched a messenger to
Ma'i III and Tefa'aora II, entrusting them with the government. They subsequently conveyed this decision to Tamatoa, although the inhabitants of Taha'a refused to grant their consent. Once ready, Tamatoa led the people of Taha'a to Vaitoare, and Tapoa withdrew to
Tiamahana, where he fortified his position and refused any further retreat. At this time a deacon of Ra'iātea died suddenly and Tamatoa himself fell gravely ill, necessitating his return to Ra'iātea.
Tapoa, anticipating his own death, sent a messenger to
Bora Bora declaring that if his allies wished to see him alive they must come immediately, for he would not flee. The appeal succeeded and numerous lesser chiefs and warriors, stirred by the message, embarked to join him. Throughout these events the principal chiefs continued to negotiate for peace with the support of the English missionaries.
George Platt accompanied Teari'ifa'atau, a chief of Huahine, in his whaleboat to Taha'a where they met Tera'imano, daughter of the late
Tenani'a, acting as messenger for Queen
Teri'itaria II. Tapoa accepted the proposed conditions of peace and the delegation proceeded to Ra'iātea where Tamatoa lay seriously ill. After discussion he agreed to the terms. The warriors removed their cartridge boxes and laid aside their arms, and it was resolved that the kings of the five islands
Huahine, Ra'iātea, Taha'a, Bora Bora and
Maupiti would convene to settle the matter amicably. Teari'ifa'atau returned to Huahine and George Platt to Bora Bora hopeful that peace would prevail, accompanied by a number of Bora Borans. Within days King Tamatoa III died at Raiātea in the presence of the missionary
John Williams, his family, and the chiefs of Huahine. ==Succession==
