Patton’s diaries are part of a larger collection of his papers at the Library of Congress. They “…illustrate Patton’s activities during the Mexican Punitive Expedition, World War I, and World War II. The volumes, particularly from 1942 to 1945, document Patton’s daily activities and observations and reveal his candor about himself, personally and professionally.” General “Vinegar Joe” Stillwell’s diary is also available for perusal, covering a similar period but dealing with another part of the world in conflict. Both sites provide transcriptions of the diaries for ease of reading and understanding.
