This contest winning map might be worth a download, but personally I am not so sure about that.
I added a txt - file into the zip, which pretty much explains the trouble you are heading for.
The story comes with the map.
A High Treason is to be played first then to be followed by A Pleasant Return (SH) to keep things in chronological order.
It shows an unusual scenario involving the "destroy cathedral" event, which I uploaded to the utility section of SHH the other day to make it accessible for everybody.
In this I wanted to imitate a skirmish trail type of mission. That is to say that one needs to stabilize one's own economy and then counterattack under the pressure of both:
A constant flow of harrassing attacks and a rigid time limit.
(The time limit is absent in the original skirmish trail though.)
There is a time window for the best moment of counter attack to fulfill the goal.
One should not underestimate the enemy's fortress and forces and therefore gather an attack force which must represent these qualities: Strength and diversity!
Let me know, if you have a question. At www.stronghold-knights.com you can meet me soon or over here at SHH.
All my very best
