Hemingway makes use of some very important symbolism in this novel. Even as early as the first paragraph, he sets up two major symbols — the plains and the mountains — which will be in conflict throughout the story. Hemingway represents the plains as dangerous, miserable, dry, and barren. The mountains, on the other hand, represent safety, happiness, and good health. The military action that Frederic Henry witnesses takes place on the plains, and his escape, through the cleansing, baptismal ritual of jumping into the river, reaches its end in the secluded mountain chalet with Catherine. But when Frederic must take Catherine out of the mountains and back down to the city below to the hospital where she is to give birth, disaster strikes again. Rain is another important symbol throughout the novel. Often the rain suggests impending doom; there is a storm the night that Frederic learns he must leave Italy at once to avoid being arrested, Catherine dreams that she is dead in the rain, and indeed at the conclusion of the novel, it is raining when Frederic returns to his hotel.
