===Invasion of Maui===
In 1790, while the aliʻi [[Kahekili II]] was on Oʻahu, Kamehameha's army invaded Maui with the assistance of John Young and Isaac Davis. Using cannons from the ''Fair American'', they defeated Maui's army led by Kahekili's son [[Kalanikūpule]] at the bloody [[Battle of Kepaniwai]] .<ref name=":0">{{Cite web|title=Kamehameha the Great|url=https://home.nps.gov/puhe/learn/historyculture/kamehameha.htm|url-status=live|publisher=National Park Service|archive-url=https://web.archive.org/web/20211025160426/https://home.nps.gov/puhe/learn/historyculture/kamehameha.htm |archive-date=October 25, 2021 }}</ref>

In 1791, Kahekili, supported by his brother [[Kāʻeokūlani]], aliʻi of Kauaʻi, reconquered Maui and also acquired cannons. In April or May 1791, Kahekili tried to invade the island of Hawaiʻi, but was defeated in a naval battle called Kepuwahaʻulaʻula near [[Waipio Valley|Waipiʻo]].{{sfn|Kuykendall|1965|pages=35–37, 39}}
