Time to use those Special Powers!!!
Start in the upper right hand corner of the map. Use 10000 gold pick 6 enemy AI have them be a team against you. You will have to act quickly to win. This map can be beaten without special powers if you want a real challenge. It took me 20 or so times but I finally found a way to win. I will describe what I did below.
Tips: Only read if you are having trouble beating this map without special powers. To win without special powers use the fire ballista to set fire to the enemy outposts in the castle closest to you (blue) it will spread to the rest. Then have your knights block all enemy gates that they can reach. Only send 3 or so for each gate. This will also set of some of the fire traps. Then have all of your catapults, macemen, archers and crossbowmen ( I make extra horse archers) gather at the bottom of the slope of the castle to the south of you ( yellow and light blue) . At the bottom of the slope use the catapults to destroy all the towers and enemy outposts. If you go up the slope and fire the catapults they may destroy themselves so I use them at the bottom. Then move a few up and have them destroy the enemy walls, next send in the macemen to kill both enemy lords. Then watch out for lions. Save the game. Next take out the enemy lord to the left (purple) using catapults and macemen. Then destroy all of the stairs of the lord on the far left (orange) so that they cannot send any more enemy troops at you. With luck and skill you will have bottled up the rest of enemy lords in their castles and can then build up your economy to destroy them. Then take out the enemy in the middle (blue) and then the upper left (black). I saved orange for last. You will see why. Be sure to save frequently. Even with only orange and black left you still could be overwhelmed. Well that's it good luck and just have fun.
