Human lord (4,000 gold) v Pig, Duc Truffe, Pig, Duke of Pigsbury & Pig "The Hog" (all 2,000 gold)
This mission pits you against three AI lords, and with the prospect of not only having to defeat them, there's the small matter of defending against one of the more aggressive AI characters in the game. If left to build up a steady economy the Pig in his various guises can be annoyingly stubborn to overthrow.
The map is very unbalanced here, and in your favour. There are masses of iron deposits sited behind your keep and a healthy outcrop of stone. These will become vital. Oasis ground is present through the middle of the map, but it isn't really required.
To start off with I placed a few woodcutters' huts and ensured I had enough ale present to support a couple of inns. The marketplace was put in place from the start too. As soon as they began working, I turned off food consumption and sold the remaining starting food. As wood began to hit the stockpile, I placed iron mines on the outcrop of ore, and quickly built up a very frequent supply. By placing hovels quickly, and increasing the number of inns, I could dedicate most of my workforce to iron extraction.
I initially placed a hop farm on the oasis grass. As my economy blossomed I found it easier to either buy hops & manufacture ale, or just buy ale straight from the marketplace.
Defending my settlement was achieved by buying crossbows and leather armour. I found that the macemen were too quick and too well protected from damage to justify the cheaper archer units. A small castle was built and two large square towers at the corners facing the line of assault armed with ballista helped to knock out the Pig's catapults.
With a continuous supply of iron, plus a decent amount of stone, I was able to recruit all of my crossbowmen and macemen rather than manufacture. Attacking the Pigs' castles involved a force of predominantly catapults and crossbowmen. Macemen were used to attack the AI lords more than anything. Knocking out their towers and gatehouses allowed me to get closer than normal and with large numbers of crossbowmen I found I could wipe out any attacks on my positions with little fuss. Once again I found that I had more units than required, the final Pig falling with a generous number of my own units still in full health.
