But, Ravinale is getting reinforcements, heck we all ready have 50 soldiers from the Madrid, and that number is sure to increase.
Yes, yes, the resistance lost their leader in a battle, but we don't really know how strong the Cult is. The resistance seems quite small, if the Cult has an "army". When we start out, the resistance is a small gang, that is somehow able to not only break into a heavily guarded cult prison, but thwart the enemy's plans at every corner. I don't think the Cult is as strong in Ravinale as you seem to believe. Ravinale doesn't seem to be that big of a city, and they threw out a large portion of the guard. Their strength is all the brainwashed civilians. Of the people we've met, they are either mostly neutral or against the cult. Word of the resistance is very well spread. If the cult really had that much of a hold on the people of Ravinale, such rumors would not spread. Sorry, but the Cult is weak, or at least it is in Ravinale. Perhaps their main forces are off in some distant land, but I don't see the Cult as a force to be reckoned with, just a lot of very persuasive politicians and priests with true warriors few and far between.
