Battle song, how war was won. [urgently needed]

We particularly need a song for scene 29 which tells the story of how an army of 100 beat an army of 40,000. In scene 29 you can see ideas of where dialogue can form the verse with the chorus being repeated inbetween. This could be one of those songs that tell a story. An example of a song with a Latin beat that tells a clear tale is ‘Copacabana’.  Or ‘The Ultimate Showdown’ is a very different example of a song that tells a story of various battles. Or the song could focus on ‘achieving the impossible’ and have that as a recurring theme.
