However, the attack by the navy diverted enough of the defenders to make the army assault successful, and the fort was taken. Lamson's friend and fellow officer Samuel W. Preston was killed in the assault. Lamson resigned from the Navy on July 6, 1866, and returned to Oregon, where he was appointed to be clerk of U.S. Customs. On January 9, 1895, he was reappointed lieutenant and placed on the retired list on April 15, 1895. Lamson died in Portland, Oregon, on 14 August 1903, and is buried at the River View Cemetery there. Namesakes Three U.S. Navy destroyers have been named in his honor.
