I'm new to the game and the series as a whole so I'm really confused on how the crusades work. We always have way more troops and it shows that the war score is green so we're winning but then after awhile it says we lost. It's happened like 6 or 7 times now and I'm getting to the point where I'm just gonna tell them they're on their own but when I do that I lose something, I dont remember exactly what it is right now, and then after a month or so they just ask me again so saying no doesn't really do anything.

TLDR: How do Crusades work and why are we losing every time when the war score says we're winning?
