The enemy are well positioned. We're taking heavy causalities before our men can get a foothold on the battlements!
Let's try to split the enemy forces by ordering our men to climb some undefended areas.
Our men are under fire from those towers! Once we're inside the walls, we should move quickly to capture them. If we order
a unit into the marked area surrounding a tower, it will eventually fall under our control. We can then turn that hail of fire on the enemy.
We can capture and gain control of the gatehouse in the same way. Now we've seized the main gate, we'll order
our cavalry to flood into the castle and slaughter the remaining defenders!
With the outer defences breached, let's edge our men towards the inner wall and head for the tenshu. Capture that, and the
battle will be won. The castle and the campaign province will be ours for the taking!
