All, re the below:-
I am pleased to say that even though I did make an error, it would seem that the end result was indeed correct. I don't want to ruin for those who haven't watched so please head straight on down to the video and read no more.
Folks, apologies for this but I made an error and forgot to take unit strength into account for the cavalry (thanks to rathnutt1 of warhammer org for spotting it) :-

Anyway, please view it for entertainment value only (well the noises are the best afterall !)
I need to go back and check the rule book !
My new Hellblaster Valley skirmish should be ok though - because I reread the rules as I went along :)
Apologies for my mistake.
