Besieging a castle, i was waiting for a siege tower to be built when the (enemy's) cavalry came to (not my) rescue. These were khergits, see. Entirely composed of cavalry. But i brought a cavalry-heavy army too. But they outnumbered us two to one. And retreat wasnt an option.
when the game loaded, i was perched atop a hill in a wooded area. And i got an idea. This is terrible cavalry terrain, especially for the enemy. Trying to overrun my position. But i didnt need my cavalry getting shot off the tops of their horses while holding position, so i ordered them to hold position in front of our line, then dismount, then fall back to our line. The plan worked. When the khergits got there, they had been split into smaller groups by the trees and hills already, and werent at top speed. Then a large number of them ran right into our horses, which were standing between us and them. Sharpshooters and i got a few kills right there just because they came to a dead stop and got stuck. The remainder that didnt run into our horses ran into the line of infantry and cavalrymen and were overwhelmed. That broke the first wave easily, and i ordered the cavalry to remount horses and charge. From then on the fact that the swadian men at arms and knights are much tougher than the average khergit insured that we won. Not without casualties, but i had enough men to take the castle afterwards (most of them died, though, deapite khergit troops being aweful at holding castles)
I thought that was a neat trick. The ai isnt very smart anyway.
But the khergit kingdom fell a while after that; now all their lords are abandoning them. Still, cavalry battles are reasonably fun, so its gonna be somewhat boring from here on out with both them and the swadians under our thumbs.
