That night Kekuaokalani took up his line of march for Kailua, determined to give battle to the royal forces wherever he might encounter them. He moved near the coast, and the next morning the hostile armies met at Kuamoo. Arranging his forces in order of battle, Kekuaokalani sent to the front a number of newly-decorated gods in the charge of priests, and, in turn addressing the several divisions, conjured them in impassioned language to defend the gods of their fathers.
Kalaimoku commanded the royal army in person. The battle opened in favor of the rebels, and with them would have been the victory but for the great superiority of the royalists in firearms. At a critical juncture a battalion of musketeers, some of whom were foreigners, charged the rebel centre, when the division gave way in something of a panic, and soon the entire rebel forces were in retreat. Retiring to the adjacent seaside, under cover of a stone wall they made a successful resistance for some time; but the squadron of double canoes already referred to, under the command of Kaahumanu and Kalakua, enfiladed the position with musketry and a mounted swivel, and the insurgents abandoned the unequal struggle, the most of them scattering and seeking shelter in the neighboring hills.
Although wounded early in the action, Kekuaokalani gallantly kept the field. Everywhere was his tall form seen moving throughout the conflict, rallying and cheering his followers, while at his side fought the brave Manono. He finally fell with a musket-ball through his heart. With a wild scream of despair Manono sprang to his assistance, and the next moment a bullet pierced her temple, and she fell dead across the body of her dying husband. Kalaimoku was the first to approach, and gazing long upon the noble features of Kekuaokalani, grand even in death, turned to his followers and said: “Truly, since the days of Keawe a grander Hawaiian has not lived!”
Thus died the last great defenders of the Hawaiian gods. They died as nobly as they had lived, and were buried together where they fell on the field of Kuamoo.
Small bodies of religious malcontents were subdued at Waimea and one or two other points, but the hopes and struggles of the priesthood virtually ended with the death of Kekuaokalani.
