Tactical discussion: AFDS (anti-Fell Beast

[Essex]

Ah, but my lord, it is my sad duty to tell you that in the first example the creature was not slain

how do you know the fell beast wasn't slain, because if it was it closes a big plot hole with the nazgul not being able to report back to sauron in time........also someone posted a few weeks back that they only saw 7 fell beasts at the black gate I believe.......
