This was the first 'Pitched Battle' battle plan I played through when I got the back back in June. I have played through most of the Pitched Battles and this is still my favourite.
The board is split diagonally with three objectives along the middle line, you then split your army into 3 groups, the first group are set up from the beginning, the 2nd arrive in your second hero phase and 3rd in your third hero phase.
Who ever finished setting up first decides who has the first turn. You win the battle by gaining the most points from controlling objectives, to gain points you need more of your models within 6" of the objective at the end of the round. Scoring starts from the second battle round.
