A barricade in neutral territory will use up the movement points of any unit that goes onto that square.
But did the barricades block the enemy movement, I'm quite sure I read something like that in civpedia (or whatever it is called)
Do you mean defensive bonus? If you attacke an enemy on the mountain they have a defensive bonus from the mountain and they'll have an extra bonus because you're attacking over a river. If they attack you from the mountain, you'll have a defensive bonus because of the river, but the mountain makes no difference.
edit: but I'm not sure that the tile SE of the mountain is truly "across" the river since the river appears to originate in that tile. I sometimes get an unpleasant surprise when I found a city that I think is on a river and it turns out not to be.
The question that has ALWAYS bothered me, and never been answered to my satisfaction:
What determines the expansion of your palace?
The mountain above: I would right-click the mountain to see if it gets a gold bonus from being next to a river. In that case, the river must run between the tile where the settler stands and the mountain. If there is no gold bonus from the mountain tile, there's no river between the settler and the mountain.
