You forgot that I would get points for taking the city, which was 700 points and plus I killed every defender in the city, so that would have gotten me point for that. So I knew that I had enough points to win. What was suprising was the fact that the Abbasids has Assains, but they did not attack me when I landed. I was sure they would have used them since I had a peak at Jerusalem before I declared war on them. For some reason they moved to the hill next to Jerusalem, because they attacked me after I pressed enter. Considering that I knew that I had won the game, Jerusalem was not well defend and thus they retook the city, but it was too late by then.
