right now they're in the second night.
the reason it doesn't take long is because this for isn't about obtaining new lands. it's about destroying the enemy. so both of the forces went up against each other with full force from the beginning. no strategies. just use whatever you have to crush the enemy.
the previous wars was about obtaining new lands. and to do that you need to fight in many different locations. use strategies and deploy people just about enough. that's why in some battles one side wins and in some other battles other side does. with the situation like this war just keeps dragging on.
