made it

As in you beat it? What was your strategy? Ive been able to breach both areas by digging in a moat on the west side and tunneling but it costs too many troops and I don't have enough left to kill all theirs.

First i send all the spearmen to fill the front wall moat. Once i have a coupe of squares filled, i call them back and send some of the tunnellers. When it's done all non-archers fighting units go in to kill everything, then the archers take place on the towers and kill all units in range. Finally I tear down the last wall and send everyone in, most of the units will only serve as distractions while the macemen do their job.
