The soundtrack used as General Sherman's theme is Marching Through Georgia, which is appropriate as this iconic song was written in 1865 as apologist propaganda for his Georgian campaign of the previous year. It was written by Henry Clay Work who also wrote the song "Kingdom Come" used as General Grant's theme.
The soundtrack used as General Grant's theme is Kingdom Come (sometimes called Year of Jubilo), a minstrel show song written in 1862 by Henry Clay Work (see also trivia about Sherman's theme). This catchy, rollicking tune has appeared in other popular movies such as Meet Me in St. Louis (1944) and several cartoon shorts by Tex Avery. However, no movie, except one which requires a strictly accurate historical context, would dare to use the original lyrics, which are quite offensive by modern standards. As an example, the first line is "Say, darkey, have you seen de massa wif de moustache on his face?" and it only goes downhill from there.
