It has now been more than 140 years since William T. Sherman and his 60,000 man army burned their way through South Carolina and by doing so earn the everlasting hatred of every South Carolinian alive at the time and of their descendants (some 7 generations worth). No, there is no way that I will go into this can of festering worms here. However, as a historical event, Sherman's March through South Carolina and the resulting destruction of the state's railroads is an interesting subject.
Some six months after the state was Shermanized, northern journalist Sidney Andrews toured the former Confederacy to report on the political, economic, and social conditions in the aftermath of the South's defeat. Andrews' articles (more than 40) in the Boston Advertiser and the Chicago Tribune were so popular that in 1866 Andrews published them as a book, The South since the War: As Shown by Fourteen Weeks of Travel and Observation in Georgia and the Carolinas. Excerpts from this book of Andrews travels on South Carolina's railroads (link) offers a grime picture of a war ravaged state. Andrews' complete book is available on-line here.
For everything you wanted to know (but were afraid to ask) about Sherman's March through South Carolina go here. You can also sit back and watch this online video documentary on Sherman's march.
To offer some balance to the Northern view are the observations of southern diaiest May Chesnut while traveling to her home near Camden during May 1965. An on-line version of her diary is available here.
