Artillery is crucial. With cannon in our ranks, we can target the outer walls and have our men break through their defences.
With our cannon selected and in range, we'll right-click a wall area to target fire.
There's another way we can overcome the walls: our Ninja and infantry units can be ordered to scale them. We'll also order
our cavalry units to dismount and make the climb.
With a unit selected, we'll choose an area of the outer wall to attack. Notice that our cursor changes; this tells us that this unit
can climb here.
Any infantry unit can climb a wall but heavily armoured troops are slower. They're more likely to suffer casualties as a result.
Ninjas come into their own here. Their agility and light armour make short work of scaling the wall and they're equipped with
climbing claws, designed for the task at hand.
