My small army of about 5 musketeers, three horsemen, roughly 15 infantry of various skills, and me, finally catches up to a group of bandits we'd been chasing. Unfortunately, another group of bandits was in the area and joined the fight, bringing the total up to 60 bandits versus my army of roughly 25.
As luck would have it, we were positioned on top of a small hill (more of a bump, really), and the bandits had to charge through open ground to get to us. I ordered the entire army to hold position while I went in to harass and delay the enemy. Firing a few carbine rounds managed to get their attention, and I soon had roughly fifteen infantry chasing me while bandit musketeers did their best to hit me. I had to keep attacking them however, or they'd give up the pursuit and go after my troops instead. A few tried, only to get cut down more or less simultaneously by an exceptional round of shooting.
All this time, I'm firing my carbine whenever I have a decent shot, and swooping in with my sword whenever a nearby bandit was busy reloading. I order my men to charge the decimated scum, only for the bandit reinforcements to arrive. I can't disengage long enough to order them back to their places, and the musketeers are nearly out of ammo anyways, so I charge directly into the new bandit army, breaking their ranks enough for my fellow horsemen to punch through as the infantry move in as fast as they can.
When the final totals came in, I had only lost a single mercenary halberdier. All 60 bandits died.
