This is the story of an American ambulance driver on the Italian front and his love for a beautiful English nurse. Hemingway's frank portrayal of the love between Lieutenant Henry and Catherine Barkley, caught in the inexorable sweep of war, glows with an intensity unrivaled in modern literature, and includes a devastating description of the German attack on Caporetto--lines of tired men marching in the rain, hungry, weary, and demoralized.
