Decades later, Armstrong wrote an autobiographical account based on his travel logs, chronicling his thrilling, gritty experiences during his ten years overseas. His memoirs describe his encounters with other whalers, beachcombers, Peruvian villagers, Pacific Islanders, Maori warriors in New Zealand, cannibals on Fiji, and the impacts of American expansionism. He also recounted his struggles with drink, his quest for God, and his own redemption.
Armstrong's gripping personal account is bookended by thoroughly researched contextual background compiled by Alexander Brash, a noted professional conservationist. Brash fills out Armstrong's intimate and timeless tale by shedding further light on whaling and its impacts, his ancestor's religious milieu, and the importance of marine conservation today. A Whaler at Twilight is a fascinating dive into both human morality and American history.
