King Richard has made a gigantic mistake. Phillip Augustus of France has retained both banks of the River Seine. He can unite his armies at Andeley, and be attacking Rouen, the capital of Normandy, within two days. All his heavy seige engines can be transported by boat down the Seine.
To protect Rouen, King Richard has resolved to construct a fortress complex at Andeley, called Chateau Gaillard. The fortress will feature a log barrier across the Seine, a fortified bridge, and two fortified villages. All this is a prelude for a huge castle that will sit on a high ridge and be the final defence of the complex.
"So my Lord, I call on you to be my main builder," Richard informs you. "You have built castles for yourself, now I want you to use your skills for me."
Richard unrolls a map.
"Grand Andeley is already weakly fortified. I want you to block the fords over the river, to protect the iron works and the quarries we will need to build my Stone Daughter. Fortifiy my bridge, and the new village of Petit, or little, Andeley. We will need much food for the large work force I am importing. Frenchmen will try to slow down or stop the construction; this must not happen."
King Richard fixes you with a powerful glance. "This fortress Must be completed. Do you understand me ?"
Revision: Comments by a player have pointed out some flaws. I have made the enemy attacks stronger, and cleared up some of the problems with bandits and the enemy fighting each other, and not attacking you !
Hints: The enemy attacks all come from the left, the historical north. The barbican at the ford in front of Grand Andeley is too weak. It needs a stone gatehouse and towers. The enemy likes to attack toward the top of the map, then ford the river and attack the castle and quarries.
The main gates need barbican protection, to absorb enemy rocks and force the enemy to deploy farther away. Wide moats are a good idea; they can be built on both sides of the river, to slow down attacks. Use pitch as your OPEC oil, selling it off for money.
