At Klamath Lake in southern Oregon, Frémont's party was attacked by about twenty Native Americans on the night of March 6, 1846. Three men in camp were killed. The Native Americans fled after a brief struggle. Carson was angry that his friends had been killed. He took an axe and avenged the death of his friends by chopping away at a dead Klamath's face. Fremont wrote, "He knocked his head to pieces."
