The mongols probably retreated because they got the last reinforcement stacks. The initial horde will wander into asia minor, get reinforcements, head back to the reinforcements, then resume their path to whatever they want to do. To avoid this, edit the campaign script file so that all the mongols appear within the first couple of turns. See Factionheirs guide in the mod tutorials forum for how to do this.

As for the other attacks, well... France wants to kill you. The Danes really love the netherlands, and will attack there no matter what. The byzantines wants to reclaim its old empire, and antioch is a part of it.
