In my U.S. History class I have been using old songs from the Civil War Era to help my students better understand the war and the way it divided the nation.  So far I have used "Lincoln and Liberty", Battle Hymn of the Republic, Dixie, and An Old unreconstructed.  I am also planning on using " Give us a Flag"  I was wondering if anyone else had any suggestions as to songs that would be useful for giving students a handle on the War or if anyone had any information for futher interperting these songs as often I have the lyrics but very little other information about them.  I'm open to suggestions.....
