The Personal Memoirs of U. S. Grant is an autobiography by Ulysses S. Grant, the 18th President of the United States, focused mainly on his military career during the Mexican–American War and the American Civil War, and completed as he was dying of throat cancer in 1885. The two-volume set was published by Mark Twain shortly after Grant's death. Candidly depicting his battles against both the external Confederates and his internal Army foes, it has been highly regarded by the general public, military historians, and literary critics.
