The Holy Roman Empire attacks one of my cities in force. Over 750 men against roughly 360 defenders. Fine.
During the pre-battle speech, I notice that my units don't seem to be anywhere near each other. That's worrying.
As soon as the battle starts, I notice 2 things. One is that an enemy spy has apparently managed to open the gates of the city, letting the invaders stream in. The second is that of all of my units, only two (the weakest) are actually at the front gates. The rest are scattered throughout the city, some even on the opposite side!
This battle is already lost. All I can do is fight to the bitter end.
...or at least, that's what I thought in the first couple of minutes. I quickly pull everyone back to the city center, where they become unbreakable. They still become less skilled as panic mounts, but they will never run away and that's what I need at the moment. One unit of longbowmen gets stuck and fails to make it to the center, but thankfully the AI is focused on attacking the main bulk of the army and the longbowmen are allowed to pester the Imperials throughout the battle. The Imperial 4-star general dies in the first charge to my spear militia, and the rest of the battle consists of waves of infantry charging my knot of desperate units as they weather storms of bolts and arrows and turn away each attack in turn. Eventually one Imperial unit routs. Then another. Then another, and another, until finally the battle ends in my favor.
I'm down to 120 men and the enemy army is still 400 strong, but we won this day.
