At least over here, there was actually a battle, and they kept sending reinforcements to a lost cause - which is always a bad thing to do.
Apparently, they themselves saw it as a battle, because we know that they had a secret general who behind the scenes directed what to say and when. When one of them starting using normal arguments, he was immediately silenced by another who was apparently their drill sergeant. Their commander must have believed that we could not be beaten by our own weapons: serious debate. So he chose to use suicide trolls!
