River borders

[Gilrandir]

MTW regions guide contains a lot of useful information, but what could improve it is the list of river borders between provinces as attacking (or defending) it is a great advantage to know whether you will face a bridge battle. I wonder if someone compiled such a list.

There is no need for such a list as you can find that info in game.

Right click on a province and at the bottom of the province description there is a decription of the province terrain. Then move the mouse from that province to any other neighbouring province. The terrain info will change to tell you what the crossing there is (river or non river and what terrain).

You can tell if an invasion will have a bridge on the campaign map by popping open a province details scroll, and moving the mouse around the bordering provinces. Text in the scroll will appear about attack details.

The MTW wiki has the map types for every border attack/defense/assault in the game, just go to the province. Khazar (https://forums.totalwar.org/wiki/index.php/MTW_Khazar) is a good example, it's got plenty of rivers.

You can also look at the EARLY.txt file, river maps are chosen based on the SetBorderInfo:: lines. Quick grep gets the following list:
