Very impressive looking battle!
The objective system is very interesting.... a while back I was asking for ideas / inspiration for scenarios and such to spice up medieval battles, and had mentioned I was impressed with the Two Fat Lardies approach after seeing a game of Chain of Command on youtube. Someone (perhaps it was you?) said similar things could adapt well for medieval large-scale battles, and I can see here how that would work.... I've added the idea to my 'scenarios' notebook!
