The eldest of the sons of Kamauaua was Kaupeepee. He was a warlike youth, well skilled in arms and mighty in strength and courage, and so profound was his detestation of the alien chiefs that he resolved to devote his life to such warfare as he might be able to make upon them and their subjects. With this view he relinquished his right of succession to his first brother, Keoloewa, and, gathering around him a band of warriors partaking of his desperation and courage, established a stronghold on the promontory of Haupu, on the north side of the island, between Pelekunu and Waikolo. At that point, and for some miles on each side of it, the mountains hug the ocean so closely as to leave nothing between them and the surf-beaten shores but a succession of steep, narrow and rugged promontories jutting out into the sea, and separated from each other by gorge-like and gloomy little valleys gashing the hills and, like dragons, for ever swallowing and ejecting the waves that venture too near their rocky jaws.
One of the most rugged of these promontories was Haupu. It was a natural fortress, precipitously fronting the sea with a height of five hundred feet or more, and flanked on the right and left by almost perpendicular declivities rising from narrow gulches choked with vegetation and sweetening the sea with rivulets of fresh water dashing down from the mountains seamed by their sources. It was connected with the range of mountains back of it by a narrow and rising ridge, which at a point something less than a mile inland, where opposite branches of the two flanking gulches approached each other closely, was contracted to a neck of not more than fifty paces in width. The summit of the point abutting the ocean was a comparatively level plateau, or rather series of three connecting terraces, embracing in all an area of nearly a hundred acres. Surrounded on three sides by almost perpendicular walls, and accessible on the fourth only by a narrow and easily-defended ridge extending to the mountains, little engineering skill was required to render the place well-nigh impregnable.
Setting himself earnestly to the task, Kaupeepee soon transformed the promontory of Haupu into one of the strongest fortresses in all the group. He surrounded the plateau with massive stone walls overlooking the declivities, and across the narrow neck leading to the mountains raised a rocky barrier ten feet in thickness and twenty feet in height, around which aggression from without was rendered impracticable by the excavation of precipices leading to, and in vertical line with, the ends of the wall. Instead of a gate, a subterranean passage-way led under the wall, the inside entrance being covered in times of danger with a huge flat stone resting on rollers.
Although the passage was rough and in unfavorable weather attended with danger, canoes could enter the mouths of both gulches and be hauled up beyond the reach of the waves, and beyond the reach of enemies as well; for above the entrances, and completely commanding them, frowned the broad battlements of Haupu, from which might be hurled hundreds of tons of rocks and other destructive missiles. With ingenuity and great labor narrow foot-paths were cut leading from the middle terrace to both gulches, some distance above their openings, and affording a means of entering and leaving the fortress by water. These paths connected with the terrace through narrow passage-ways under the walls, and a single arm could defend them against a host.
Within the walls buildings were erected capable of accommodating in an emergency two or three thousand warriors, and on the lower terrace, occupied by Kaupeepee and his household, including his confidential friends and captains, a small heiau overlooked the sea, with a priest and two or three assistants in charge. Mountain-paths led from the fortress to Kalaupapa and other productive parts of the island; and as fish could be taken in abundance, and Kaupeepee and many of his followers controlled taro and other lands in the valleys beyond, it was seldom that the stronghold was short of food, even when foraging expeditions to the neighboring islands failed.
The services of the courageous alone were accepted by Kaupeepee, and it was a wild and daring warfare that the little band waged for years against the alien chiefs and their subjects. They could put afloat a hundred war-canoes, and their operations, although usually confined to Oahu, Maui, and Hawaii, sometimes in a spirit of bravado extended to Kauai. Leaving their retreat, they hovered near the coast selected for pillage until after dark, and then landed and mercilessly used the torch and spear. This part of their work was quickly done, when they filled their canoes with the choicest plunder they could find or of which they were most in need, and before daylight made sail for Haupu. Women were sometimes the booty coveted by the buccaneers, and during their raids many a screaming beauty was seized and borne to their stronghold on Molokai, where in most instances she was so kindly treated that she soon lost all desire to be liberated. Occasionally they were followed, if the winds were unfavorable to their retreat, by hastily-equipped fleets of canoes. If they allowed themselves to be overtaken it was for the amusement of driving back their pursuers; but as a rule they escaped without pursuit or punishment, leaving their victims in ignorance alike of the source and motive of the assault.
A prominent chief of Oahu, whose territory had been ravaged by Kaupeepee, traced the retiring fleet of the plunderers to the coast of Molokai, when it suddenly disappeared. He landed and paid his respects to the venerable Kamauaua, then at Kalaupapa, and craved his assistance in discovering and punishing the spoilers, who must have found shelter somewhere on the island. The old chief smiled grimly as he replied: “It is not necessary to search for your enemies. You will find them at Haupu, near the ocean. They are probably waiting for you. They do not disturb me or my people. If they have wronged you, land and punish them. You have my permission.”
The Oahu chief offered his thanks and departed. He made a partial reconnoissance of Haupu, ascertained that it was defended by but a few hundred warriors, and shortly after returned with a large fleet of canoes to capture and retain possession of the place. Arriving off the entrance to the gulches, and discovering a number of war-canoes drawn up on their steep banks, he opened the campaign by ordering their seizure. Sixty canoes filled with warriors rode the surf into the gulches, where they were met by avalanches of rocks from the walls of the fortress, which dashed the most of them in pieces. The chief was startled and horrified, and, believing the gods were raining rocks down upon his fleet, he rescued such of his warriors as were able to reach him from the wrecked canoes, and hastily departed for Oahu, not again to return.
It is said that Kamauaua watched this assault upon Haupu from the hills back of the fortress, and, in token of his pleasure at the result, sent to Kaupeepee a feather cloak, and gave him the privilege of taking fish for his warriors from one of the largest of the royal ponds on the island. He also quietly presented him with a barge, than which there were few larger in the group. It would accommodate more than a hundred warriors and their equipments, and was intended for long and rough voyages.
These barges were constructed of planks strongly corded together over a frame, and calked and pitched. They were sometimes ten or more feet in width, and were partially or wholly decked over, with a depth of hold of six or eight feet. It was in vessels of this class, and in large double canoes of equal or greater burden, that distant voyages were made to and from the Hawaiian Islands during the migratory periods of the past, while the single and double canoes of smaller dimensions, hollowed from the trunks of single trees, were used in warfare, fishing, and in general inter-island communication. After the final suspension of intercourse, in the twelfth century, between the Hawaiian and Society Islands—the possible result of the disappearance of a guiding line of small islands and atolls dotting the ocean at intervals between the two groups—the barges referred to gradually went out of use with the abandonment of voyages to distant lands, and were almost unknown to the Hawaiians as early as one or two centuries ago. Their spread of sail was very considerable, but oars were also used, and the mariner shaped his course by the sun and stars, and was guided to land by the flights of birds, drifting wood, and currents of which he knew the direction.
