Playing Danes defending Brughues against French siegeThey had ladders, a tower and a ram. When assaulting, a spy had opened the gates for them. They dropped the ram, climbed the walls with tower and ladders, ignoring the opened gate.
Meanwhile, I was preparing to defend the square with my inappropriately small force of viking raiders and dismounted huscarls. I was expecting my anihilation and ready to enjoy watching my own army's destruction.
The french force stood on the wall doing nothing. All they had to do was either archer me, or rush me with its infantry and Knights. It did nothing.
Although I like a good fight I'll never give up an advantage no matter how unfair. So I waited til the clock almost ran out, knowing I would win this thing, and in the last 3 minutes advanced toward the wall to see what was going to happen.
Half way there some of the hundreds of Frenchman came down "en masse" (full on) to charge my bunch. I WIN!!!

The French sued for peace. This sort of thing affects the game immensely when you consider the domino effect on future turns.
