Although it is probable that Kamehameha took part in some of the earlier wars of Kalaniopuu, he makes his first prominent appearance in tradition as a military leader in about 1775, in a battle on Maui, between Kalaniopuu and Kahekili, the moi of that island, or of the greater portion of it. Kalaniopuu was defeated, but the conduct of Kamehameha was notably cool and sagacious. It is reasonable to believe that he also took part in the disastrous campaign of the following year, when the army of Kalaniopuu was almost annihilated on the lowlands near Wailuku.

This battle was one of the most sanguinary spoken of in Hawaiian tradition. Kalaniopuu invaded the island with six heavy divisions of warriors of all arms. The members of the royal family were formed into a life-guard called Keawe, while the nobles entitled to the privilege of eating at the same table with the king composed two distinct brigades, known as Alapa and Piipii. A landing was effected on the southern side of the island. The headquarters of Kahekili were at Wailuku, between which and the coast stretched a slightly elevated sandy plain.

The Alapa took the advance, and, without waiting for support, pushed boldly on toward Wailuku. This brigade was the flower of the Hawaiian army. It was composed of eight hundred men, each one of whom was of noble blood. They were all large men of nearly equal stature, and their spears were of equal length. Marching shoulder to shoulder, with feather capes and plumed helmets, tradition describes their advance as a spectacle such as had never before been witnessed. But Kahekili was not appalled at the sight. He permitted them to approach within a mile or more of Wailuku, when he suddenly precipitated upon them a force of four or five thousand spears. The battle was a slaughter. The Alapa refused to yield or retreat, and of the eight hundred helmeted chiefs but two escaped to tell the tale of the slaughter of their comrades. But a single prisoner was taken, and he died of his wounds before he could be despatched in form and offered in sacrifice. It was historic ground. On the sandy plain many battles had before been fought, and near and above it was the sacred burial-place of Iao, where had been deposited the bones of many of the ancestors of the battling chiefs.

The next day a general battle was fought on the same ground, and Kalaniopuu was defeated. But he was not crushed. The loss of life had been great on both sides, and a temporary peace was established on the condition that the Hawaiian army should at once be withdrawn from Maui. The suspension of hostilities was secured partly through the instrumentality of the wife of Kalaniopuu, Kalola, who was the full sister of Kahekili.

But this peace was of short duration. Scarcely a year elapsed before Kalaniopuu again invaded Maui, where he continued to hold a fortified possession in Hana, and began to ravage its coasts. Without decisive results, the campaign extended into months, Kalaniopuu maintaining a foothold in Hamakualoa, but being unable to extend his conquests greatly beyond it.

II.

It was during the indecisive campaign just referred to that Captain Cook—having a few months before touched at Kauai and Niihau—returned to the Hawaiian group from the Arctic Ocean, and anchored off the coast of Maui, where he freely communicated with the wondering natives, and exchanged courtesies with Kalaniopuu and his principal chiefs, including Kamehameha.

It is now admitted that the Hawaiian group was first discovered by Juan Gaetano, a Spanish navigator, in 1555, while on a voyage from the western coast of Mexico to the Moluccas, or Spice Islands; but the secret was kept from the world, and the first European to touch at the islands, to communicate with the natives and make his discovery known, was Captain Cook.

In the hydrographic bureau of the naval department of the Spanish government exists an old manuscript chart pretty correctly locating the group and crediting Gaetano with the discovery. He named the islands Islas de Mesa, or Table Islands. It is probable that he made a landing on one of the islands with a few of his crew, since tradition refers to the sudden appearance of white men at about that period; but if he did land he left no record of the circumstance, and it is not shown that he ever returned to the group, or that any of his countrymen profited by the discovery. It has been claimed that Captain Cook was directed to the islands by an old Spanish chart of which he had in some manner become possessed; but his own evidence, as well as that of his officers, favors the assumption that the rediscovery of the islands by him was accidental.
