Ahab demonstrates erratic behavior from the very beginning and his eccentricities magnify as the voyage progresses. As the novel draws to a conclusion, the Pequod encounters the whaling ship Rachel. The Rachel's captain asks Ahab to help him in a search and rescue effort for his whaling-crew that went missing the day before -- and the captain's son is among the missing. But when Ahab learns that the crew disappeared while tangling with Moby-Dick he refuses the call to aid in the rescue so that he may hunt Moby-Dick instead.
The encounter with Moby-Dick brings a tragic end to the affair. Ishmael alone survives, using his friend Queequeg's coffin as a flotation device until he is ironically rescued by the Rachel which has continued to search for its missing crew.
Readers, teachers and students should also take note of a peculiar historical curiosity. After enjoying some success in the 1840s, the publication of Moby-Dick marked Melville's decline as a popular writer. He was unable to support himself as a writer and accepted a job at the New York Customs House. He continued to write, even as he faded into obscurity, turning to poetry in his later years. He published and went unread. Like his novel about the great white whale, his poems are also esteemed by modern critics and scholars.
