Here is a general view of Chepstow castle. You can see the general deployment of the garrrison (lower right at the base of the castle) as they come out of the castle and the approching units (bottom center) as these come on board.

I elected two commanders for the garrison and assigned commanders to each of the arriving units.

With this done I then had each player who would command a unit coming on to roll a D-10 die and the roll determined if they supported the garrison or were rebels. The units coming on board to the lower extreme right were designated as one loyal to the garrison and one against it. These were therefore enemies and began fighting almost at once. This was also rue to the extreme left. It appeared in game one that almost everyother unit coming on were enemies and had to start fighting quickly after making facing changes.

It was turn three before there were any charges and shooting for the ascending garrison units.
