As the approach is made closer and closer to Warwick it is time to hit him head on, at his stronghold. You come here with a very limited number of resources to use and because of this… you have to rob Warwick blind.
Warwick is bringing in resources along four trade routes. The more resources he gets the more units he can make. The more you get the higher your income. You start off with two cannons, a group of musketeers, John Black (hero), and Kenyenkay (hero). This very unmobile army has to rob trains. You can do this by tagging them with a unit. You then bring them home and your settlers will pick up the resources.
Strategically you need to start off by addressing the four lines of attack. There are two lines of attack on the east and two on the west. There is one tower per line of attack. This means the key to getting a lot of carts is to get rid of the towers and split up your army effectively.
In my strategy you focus on just the eastern side of the map. You use your cannons to take out towers and then position your units on a high ground area between the two points.
Rarely will the computer attack your base and when he does you can defend with your few settlers. You will want to make mostly musketeers and with all of the experience you will be gaining purchase cannons.
Once you have 4-5 cannons and a large army, you push north… slowly. The idea here is you have to take out towers and armies slowly and continue pushing forward. If you lose too many cannons too fast… you lose.
This is a mission you can play pretty safely because the enemy rarely ever attacks you. Make sure your army is huge before you engage, you will gain resources from two lines of attack when you attack so that will be some extra income.
This mission should take you no more than 20 minutes.
