Personal Memoirs of Ulysses S. Grant by U. S. Grant
"Personal Memoirs of U. S. Grant" is considered among the greatest of military memoirs. Marshalling the forces of the North in the American Civil War, he was the only general who was able to bring the South to heels. The descriptions of the great battles and his assessments of the generals, many of whom he knew intimately from the Mexican war, are worth reading.
