A pretty good scenario and in its concept quite realistic. An impressive stronghold overseeing the region but not walling it in. And a village down next to the farms. The stockpile has been replaced there! Do not raze the armoury because like many other buildings besides the weapons workshops it is not available. "Hard" then is the distance the fletchers and tanners and others have to cope with. If you want to lay trap first test the possible movement of the enemy with your knights. This will help you to not wast some amount of resources.
An excellent effect had the lose condition of losing less than 20 soldiers. Fear lay over the land.
The early date of this map may explain why so much time is given until the invasions appear. The 8 knights did a good job in chasing singl slaves and maces. As a reward for them here's a screenshot.
