The "Battle Cry of Freedom", also known as "Rally 'Round the Flag", is a song written in 1862 by American composer George Frederick Root (1820–1895) during the American Civil War. A patriotic song advocating the causes of Unionism and abolitionism, it became so popular that composer H. L. Schreiner and lyricist W. H. Barnes adapted it for the Confederacy, The Battle-Cry of Freedom.
Opening line - "Yes, we'll rally round the flag, boys, We'll rally once again" (and says "The Union forever" in the Chorus)
The Confederate adaptation opens "Our flag is proudly floating on the land and on the main" (and says "Dixie forever" in the Chorus).
