In the novel A Farewell to Arms by Ernest Hemingway, Hemingway shows Frederick Henry's progression into a code hero. Frederick Henry achieved many code hero characteristics by the end of the novel with the help of Catherine, a code hero herself. All the characteristics seem to follow the path of a person with masculine characteristics who is continuously striving to live his/her life to the fullest. Throughout the novel, Frederick Henry's behavior matures into one's of a code hero.
             In the start of the novel, Frederick Henry immersed himself into the sensual pleasures that surrounded him. Henry "had drunk much wine", and had aimlessly wondered from woman to woman in Book one of the novel. He had no self-control to contain himself from the brothels during this time. He drank heavily on a regular basis, yet he was never a sloppy drunk, and could hold his liquor very well. Henry enjoys the food he ate, the love he made, and the wine he drank whenever he felt the desire to, as a code hero often does. He could not learn to control himself until he had developed a relationship with Catherine. By receiving the support and confidence from her, he was able to change. Henry finally disciplined himself near the end of his stay at the Ospidale Maggoire.
             Henry had always had trouble sleeping as many of the code heroes do in a Hemingway novel. Henry could not sleep during the night because the night was a representation of death to him. Death to Henry was the end of all things because he did not believe in any sort of after life. If he did not asleep, he could avoid having to deal with this immense fear. As their relationship develops, Henry was often accompanied by Catherine during the nights at the Ospidale Maggoire. Henry once said to Catherine, who was already an established code hero,
             "There was almost no difference in the night except that is was an even better time."(pg.138)
