(Rome:Total War, Barbarian Invasion Expansion.)
I was the Franks, and the Vandal horde had arrived. They had quickly attacked one of my cities, which had only a meager three Levy Spearmen units and one Sword Herbann unit. I had placed the Herbann on top of my walls, and had the levy spear men form a shield wall as a group near the gateway, for all they had was a siege tower, and a ram(That got totally annihilated after a few flaming arrows from my stone walls). The siege tower had ripped up half of my sword herbann units from arty fire, and the swordsmen were gutted like fish by the Vandal Chosen Swordsmen. I pulled one of the levy spear men up to the walls, to try to delay the swordsmen from flanking my shield wall. Though, to my sheer delight, the Vandal force was mostly comprised of lancers, who had charged my meager spear men, and got ground into a fine powder as a result, destroying nearly all of the vandal force while still leaving my two spear men units! The Chosen swordsmen were stabbed to death, mostly because the sword herbann went out fighting, and the horde spear men the Vandals sent up to recapture the walls had half the attack my seasoned spear men had, getting further stabbed a-plenty. This was all the infantry the Vandals had, so the gates closed, and I won.
This wouldn't be surprising, but it was absolutely pathetic, the Vandals had twice my man power, probably more than that in killing power, and they left with far less, because my lame town garrison had dropped 2 of them for every one casualty of theirs(Which on the scale the battles are, that's quite devastating). Even worse, the Vandal hordes had only managed to nab one city from me(and I had already sent in a massive army to take it back, so they wouldn't continue), and in order to recruit that kind of army back, they would have to spend years.
