The lovely symbolism in this song is absolutely staggering. I want to ramble on for hours about the lyrics, but I'm not sure I really can do justice to all the themes and all their angles. Not at the moment. Maybe after I've matured a bit. I'll just say this: though the words first call to mind the mindless bloodshed in the Crusades, they drive home a point relevant to any conflict conceived in aggression in any time period.
