The stockpile beside the keep can be deleted. If you do it quickly enough at the beginning of the level, you will probably only lose a few units of wood. Then you can start a whole new stockpile somewhere else on the map. You do not have to build your stockpile next to the keep. This was very useful on map 41, because the keep was under relentless archer attack from almost the beginning of the game, and was a very bad place to have a stockpile.
This is a composite screenshot from the crummy walkthrough I did at As you can see, the stockpile, at (1), is nowhere near the keep at all, but up on a plateau away from the fighting. That turned out to be a very important move, because I was able to have all other buildings that depended on the stockpile away from the fighting as well.
