When Walton listens to his men and turns his ship homeward rather than risk their lives , is he accurate in his statement that he has "lost (his) hopes for glory"?

This question calls for your opinion, there is no right or wrong answer. Note, had Walton continued his journey, he would likely have died. His "glory" would have been a tragedy.... not just the loss of his life, but all of the lives of his men as well. Walton will have the opportunity to better prepare if he so chooses.... to plan for the unforseen. His quest doesn't have to be over.... merely postponed.
