ATLANTA — This city would seem a peculiar place for sober conversation about the conduct of William T. Sherman.

To any number of Southerners, the Civil War general remains a ransacking brute and bully whose March to the Sea, which began here 150 years ago on Saturday, was a heinous act of terror. Despite the passage of time, Sherman remains to many a symbol of the North’s excesses during the Civil War, which continues to rankle some people here.

Yet this week, Atlanta became the site of a historical marker annotating Sherman folklore to reflect an expanding body of more forgiving scholarship about the general’s behavior. One of the marker’s sentences specifically targets some of the harsher imagery about him as “popular myth.”

“ ‘Gone with the Wind’ has certainly been a part of it,” W. Todd Groce, the president of the Georgia Historical Society, which sponsored the marker, said of regional perceptions of Sherman and the Union Army. “In general, we just have this image that comes from a movie.”
