As a side note, hey, thanks for mentioning CROSSBOW; I hadn't listened to that CD in a long time. I really liked it! I think it ranks right up there with the other Goodwin war scores, although WHERE EAGLES DARE will always the top place in my list.
I will say that the first clip seems to use an excerpt from the opening to GUNGA DIN. As to where that second clip comes from (the one that sounds like a part of Holst's THE PLANETS), although I know I've heard it elsewhere, I can not place it.
