At this time, three foreign ships arrived. Two of these vessels, the Jackal and the Prince Lee Boo were British ships under the command of Captain William Brown and Captain Gordon. The third vessel, the Lady Washington, was an American ship with Captain John Hendrick in command. These vessels were not strangers in the islands as they were foreign trading vessels and there had been frequent visits to the shores of Hawaii. It was Captain Brown who was given credit for discovering the harbor of Honolulu and naming it Fair Haven. The tender to one of the ships was the first vessel to enter Honolulu harbor.
Kalanikūpule asked Captain Brown for assistance to his army. The Captain decided to help him, as did the two mates of the Jackal and the Prince Lee Boo. These men aided Kalanikūpule’s force in what was later called the Battle of Kalauao. The muskets of the sailors drove Kaeo’s warriors into some hills that overshadowed Honolulu. They finally retreated into a little ravine. Kaeo tried to escape, but Brown’s men and Kendrick’s men saw his ahuula, his scarlet coat with yellow feathers, and fired at the enemy chief from their boats in the harbor to show his position to Kalanikūpule’s men. The Oahu warriors killed Kaeo along with his wives and chiefs.
This was a successful move, and the battle ended with Kalanikūpule as the victor. Captain Brown fired a salute to celebrate the victory. Unfortunately, the guns were loaded with shot which pierced the side of the American ship, the Lady Washington, killing Captain Hendrick and several of his crew. Encouraged by the victory over his uncle, Kalanikūpule decided to acquire the the Jackal and the Prince Lee Boo and military hardware to aid in his attack on Kamehameha on the island of Hawai'i. Kalanikūpule killed Brown and Gordon and abducted the remainder of his crew.
Knowing his enemy's disavantage, Kamehameha used his strong army and his fleet of canoes and small ships to conquer Maui, Lānai, and Molokai from Kalanikūpule's rule in 1794. Kamehameha's next target was the Kalanikūpule's base at Oahu. As Kamehameha prepared for war, one of his former allies, a chief named Kaiana, turned on him and joined forces with Kalanikūpule. Kamehameha's warriors and Kalanikūpule fought a great battle at the summit of Nuuanu Pali which is known as the Battle of Nuuanu. Following his defeat, Kalanikūpule hid in the mountains for several months before being captured and sacrificed to Kamehameha's war god, Kū-ka-ili-moku. His death brought the end of the Kingdom of Maui.
