Where are the Historical Battles found?

As the subject says. I'm assuming they're in the data folder somewhere, but I can't find them. Any help would be great.

thanks

You can find them in \data\world\maps\battle\custom\ folders.
This contains both historical battles and multiplayer scenario maps. Mp scenario's are defined by the heading
battle (3v2)_desert_siege multiplayer not_singleplayer

Thanks
