Thomas Wallace Knox (June 26, 1835 - January 6, 1896) was a journalist, author, and world traveler, known primarily for his work as a New York Herald correspondent during the American Civil War. As an author, Knox wrote over 45 books, including a popular series of travel adventure books for boys. Knox was well known for his written attacks on William Tecumseh Sherman and his Union soldiers, which reintroduced into the public debate the issue of Sherman's sanity. His work was controversial as he published important information pertaining to the Vicksburg Campaign. Knox was acquitted on spy charges but found guilty of disobeying orders. Source: Wikipedia (en)
