Shortly after Kendrick's visit to Hawaii, another trader, Simon Metcalfe killed about a hundred Hawaiians in an event called the Olowalu Massacre. About the same time the small ship "Fair American", captained by Simon Metcalfe's son Thomas Metcalfe, was attacked and captured. The "Fair American" and the one survivor, Isaac Davis, came under the control of Kamehameha. Kendrick's three men, along with Isaac Davis and a man left by Simon Metcalfe, John Young, all found their lives at risk and survived by serving under Kamehameha, teaching Hawaiians not only how to use muskets but also how to sail the "Fair American" and use its cannons. These things helped Kamehameha invade Maui and begin his conquest of all the Hawaiian Islands.
