Yes, its pretty easy to activate a third language.
Just open the file general.opt you will find in
C:\Program files\Wars in America\WIA\Settings
Open it with notepad
On the upper side you will find this:
2. *** General interface choices ***
// language (0: English; 1: Francais; 2: Espanol; 3: Deutsche)
Language = 0
ThirdLanguage = -1
Modify it so it looks like this
2. *** General interface choices ***
// language (0: English; 1: Francais; 2: Espanol; 3: Deutsche)
Language = 3
ThirdLanguage = 3
Save changes, close notepad and start the game. It shoudl be on german now.
And from now on you will be able to change from english to french or german form the options window on the main menu
