Logistic effort to grant the sufficient support and prevent attrition losses in wild terrains and in harsh weather conditions is the real challenge in the game.
Now, I sent a stack to advance deph in enemy wild areas. Then it came winter weather: in a couple of turns the stack,but leaders was fully wiped out.
It's okay. That the way thing are expected to go.
So the lesson: keep your forces sheltered in winter turn or you'll loose them!
Unfortunately, AI is missing the smartess to take in account attrition losses.
I saw it happened already many times.
AI forces keep besieging player forts, being unsupported and in harsh weather condition: in a few turns are heavily depleted. Then a sortie of a weak force of mine can easely finish them.
Other times AI forces keep running the map in enemy territory, without supply and shelter in the worst winter weather: they are depleted to destruction too.
I already reported the same issue in the past as regard BoA and in relation to NCP too.
I'm disappointed to notice it has not been improved yet.
I can accept AI to be not so smart to build up a long term strategy planning on a wide campaign as "Few acres of snow scenario".
But here the matter is quite different: attrition is a game rules. AI should be able to move while aware of its effects.
To help problem clarification and fixing I collected some screenshot to fully documentate an example.





I was playing British side.
To my offensive against Montreal and Quebeck French (AI side) forces replyed movining eastward in wild terrein. It was November turn and winter was coming. In next turns rather then looking for shelter AI forces kept on the field and wend soon decimated.
BTW, with their move in the wilderness to the southeasterd AI left Montreal unscreened and I could easely occupy it.
It's sad to be said but the campaign is not decided by fine planning but by AI mistakes.
In more than an example AI forced had just to keep control of major objectives, (as Montreal and Quebeck). Instead AI move in open fields, to be destroyed by attrition.
