I was playing my Danish campaign (about 1180 or so) and I have been doing pretty well, the Poles are subjugated, Northern Germany is mine and my war against Hungary and France is progressing nicely, however, in my most recent battle I ran into a bit of a problem. I was defending against the Hungarians and had moved my army too far up, so I could take advantage of a hill. What I forgot was the Hungarians had brought two balistas to the battle. I didn't have any small, yet effective units around, except one Arab Infantry Merc who was hired at the beginning of the game (one man, don't ask why I hadn't fired him). So I sent him charging across the field, alone, to destroy the balistas. Despite being screened by a unit of archers, a unit of horse archers and a couple of depleted units of Szelkey he made it to the first. The crew ran away in terror and my crazed Arab merc made short work of the machine. Now, despite his willingness to charge the massed Hungarian army he was getting a tad scared of all the missiles and the large infantry force that was within a few hundred feet, but he charged the remaining balista anyway. He managed to bring the balista to 90% damage before succumbing to a final hail of arrows and falling dead, despite his bravery he was credited with 0 kills. I sent forward another small unit finished off the balista and then forced the Hungarians to charge my defensive positions. They were easily slaughtered.

Never again will I scoff when a single man charges a siege weapon, thank you nameless Arab mercenary!

Anyone else have incredible tales of tiny units (1-10 on large size or so) playing important roles in battles, or at least achieving great feats of martial skill or luck?
