Based on the true story of the Cathars (Bruce Dickinson was on a holiday in the area of Montsegur, in Southern France , and was so fascinated by the tale that he wrote a song about it), this song starts with an intro reminiscent of 'The Fallen Angel' and of some of the best rockers on the Piece Of Mind album. This is without doubt the heaviest song of the Dance Of Death album, with a very strong metal guitar riffage and massive drumming, all accompanied by Dickinson's fierce and powerful voice. Quite sadly however, the pre-chorus (the part that starts with "As we kill them all...") sounds a bit too light-hearted for such a dark topic and unbalances what could have been otherwise a great song.
