I grew up in Hattiesburg, Miss. during the war years, because my Dad trained for the war at nearby Camp Shelby. People then talked of two wars, the current unpleasantness and the Civil War (War Between the States, as it was termed locally). The CW was quite vivid and there was no love lost for those carpetbaggin' dammmyankees who were now infesting the Mother Soil.
Sounds like they calmed down considerably between 1864 and 1942. In South Carolina they still often call it the "War of Northern Aggression" and until recently genteel ladies, in polite company no less, would spit every time they said the name of the general who marched Atlanta to Savannah. (Safer for monitors and keyboards in SC if I don't use that name.)
