War Movie battle scene....

Just about everyone that hears this tells me they recognize it but cant quite figure out what movie actually has it.

I was thinking Hunchback of Notre Dame, Pirates of the Caribbean, Gladiator, Troy and Lord of the Rings but none were right.

Any help?

Here's the only piece I have.

The song is 'O Fortuna' from the opera Carmina Burana
