As a youth of 18, Ernest Hemingway was eager to fight in the Great War. Poor vision kept him out of the army, so he joined the ambulance corps instead and was sent to France. Then he transferred to Italy where he became the first American wounded in that country during World War I. Hemingway came out of the European battlefields with a medal for valor and a wealth of experience that he would, 10 years later, spin into literary gold with A Farewell to Arms. This is the story of Lieutenant Henry, an American, and Catherine Barkley, a British nurse. The two meet in Italy, and almost immediately Hemingway sets up the central tension of the novel: the tenuous nature of love in a time of war. During their first encounter, Catherine tells Henry about her fiancé of eight years who had been killed the year before in the Somme. Explaining why she hadn't married him, she says she was afraid marriage would be bad for him, then admits: I wanted to do something for him. You see, I didn't care about the other thing and he could have had it all. He could have had anything he wanted if I would have known. I would have married him or anything. I know all about it now. But then he wanted to go to war and I didn't know.
The two begin an affair, with Henry quite convinced that he "did not love Catherine Barkley nor had any idea of loving her. This was a game, like bridge, in which you said things instead of playing cards." Soon enough, however, the game turns serious for both of them and ultimately Henry ends up deserting to be with Catherine.
