I know that you're not american but probably you can remember about the "Yankee Zaule Stadium" and the "Zaule Country Club" built by the Allies close to Zaule .
Have you got anything to tell us about it ?
In the link you are talking about there is a rough explanation about football matches, what I would like to hear is a description of the field made by someone who was there at that time, maybe with original pics.
Unfortunately is not you. So let's wait for somebody else to help me.
