Win condition: Rout the enemy
This battle is similarly to the previous one, but there are a few things to look out for.
All of the enemy forces are on horseback, so remember that they have extended movement compared to normal units. The enemy commander also has a higher potential for critical hits against some of your units, so watch out for that.
Most enemy cavaliers should be able to be double teamed easily for, single-turn takeouts, or even one-hit takeouts if you're using the Lightning Sword (mine was given to Tobin). When the enemy retreats, use a flying unit to pursue and eliminate them before they can reach a tower and restore HP. Take them out to clear the map.
