Bataille Empire

A division is moving on an open flank with a hill ahead of it,They are making their 3rd operational move. An enemy division is 4ud behind the hill.
So Q1 Are the enemy division classed as invisible and therefore the stopping distance away from them is 4UD not 8UD.
Q2 If a different division to the one moving can see the enemy are they still invisible?

Q1
I think 4 UD.
I must say I read it fast and thought 8 UD, but as I re-read it is 4 UD.
p 70 first bullet.
p 41 left column 2nd to last paragraph.

Q2
I don't think the second division matters. I do not recall anywhere in the rules, it saying if one unit is aware, the whole army is aware.
The closest is revealing hidden troops. That is not the issue here. These are non visible troops, which are different.

Thanks Dan, its what I thought.
Supplementary Question.
Multiple movements is 8ud of all enemy except detached skirmishers. So in the same situation a division with engage orders although it couldn't see the enemy behind the hill would have to stop at 8ud? Page 38.

I saw that. I believe that is the general rule and then the others come in to modify it. But I see your point and that is why I wrote "when I read it fast I first thought 8 UD"
