I never realized that the memoirs of Ulysses S. Grant were so interesting. My husband gave me links to a whole list of interesting free Kindle books for Christmas, including these memoirs, and they're engrossing. I read somewhere that his memoirs are supposed to be the best military memoirs ever written, even better than Caesar's Commentaries. It helps that Samuel Clemens was his editor. The section on how the army tamed mules had me laughing out loud!
