Sisters vs Chaos (The Epic Struggle)

Ok, Let's just dive right into this. It was a "kill everything" mission, since 99.9% of the people  at our store don't take the time to actually read the rulebook and read over the missions (one time, a guy said to me, "wow, that's sad," just because I knew the rules to a breakthrough mission). So, here we go. Sisters vs Chaos.

Here is the set-up. I think my army was just a LITTLE over 1000 points, but that's ok, he had an illegal army anyways (I'll explain). Just look at all that cover! WOW! Lots of space to run and hide.

Here, I swung the majority of my army around to deal with the oncoming Khorne/Nurgle/Puked on army. Lost a tank in the process, but that didn't bother me.

Sent the other tank to deal with the Nurgley infested Dreadnought, as I thought I would kill it in one turn (too bad I can't hit with my meltaguns).

Chaos advances (yawn).

Lord with Berzerker Retinue and Banner of Rage assaults my Sisters. This leaves me to wondeer, where are hits other troops?
