So, a very specific situation arose, and I'd like to try and see if anyone has experience regarding situations like this...
I'm the Queen of Gascogne (custom Kingdom). Among my territory is the Kingdom of Aragon, which seems to be a popular place for Jihads from Sunni and Shia alike.
I've beaten back two respective Jihads already, and currently I'm fighting another Shia one. So the main problem with Aragon is that the Shia like to land big numbers of troops on the island Duchy of Mallorce, where it is very difficult to drive them away.
In the last Jihad, luckily the HRE came to my rescue from boredom (as they won't leave the islands and it's not that easy for me to do a naval landing, I usually sit the Jihad out, chasing around other Shia units that come to the mainland) and staged the most massive naval landing I've ever seen to win the war for me.
This time, this isn't happening. I'm actually in a position to try and do a naval landing right now, but it is very risky still, and could cost me Aragon if I lose.
However... I noticed I am but two years away from drifting the duchy of Mallorca into the Kingdom of Gascogne.
Will it matter for the warscore when the de jure drift is finished? As of now, they're sitting at 34% due to having Mallorca occupied - if the Duchy of Mallorca is no longer part of the Jihad's target, will the number drop? It would be a lot easier to battle stragglers on the mainland down until they want a white peace.
Has anybody experienced this yet?
