Please can someone help me with music for my GCSE dance?

i need a song for my gcse dance group choreography and the stimulus is shellshock (when soliders got petrified from bombs in the trenches) from ww1 when soldiers suffered and were often shot for cowardice. I basically need a song with or without words that will bring a sense of the trenches to the audience i really want them to feel as if they are there so bombsgoing off but not a rock song or anything like that, if you know any please help, It will involve around 5 dancers and has to be 3 minutes long maximum. thanx x
