I stumbled in Reclaiming Jerusalem. You don't want to destroy any of the TCs apart from Jerusalem, since that triggers the Templars being spawned. Besides that I lost 1 caravan in Reynald's Raiders which took me a while to recover. Honestly I haven't figured out that mission, and it might be more efficient to lose some caravans. For some reason I managed to finish mission 1 in 18 minutes at some point, but I am unable to replicate it. Maybe I need to leave the monks to later and just focus on military in the first half of the game. If I wipe out the TCs of the other teams, maybe the AI takes less time to think on their turns. Part 2 went pretty well and so did Horns of Hattin.
