Will have the power ratings in a bit, but I just have to say that BuffaloBill was right: ONE of those Bavarian siege machines will see the inside of Venice. Important strategy tip, Duke of Baveria; you might want to set your retreat level a little lower than 5 when you have siege machines that are supposed to knock down the walls of a fortification level 10 City in a position where they can be attacked.
EDIT: Not that they were alone; a 387 Combat strength Bavarian army went bye-bye.
