Across the River and Into the Trees is a novel by American writer Ernest Hemingway, published by Charles Scribner's Sons in 1950, after first being serialized in Cosmopolitan magazine. The title derives from the last words of U.S. Civil War Confederate General Thomas J. (Stonewall) Jackson: “Let us cross over the river and rest under the shade of the trees.” Hemingway's novel chronicles the experiences of Colonel Richard Cantwell, an aging officer in the U.S. Army, during a weekend duck-hunting trip in Italy. Reflecting on his past and his love affair with a young countess, Cantwell's narrative captures themes of love, war, youth, and age.
