Playing as Danes, I am fighting East Anglia and Wessex. I ruined Eely (left it and they took it back), am besieging their capital and suddenly, an EA army shows up near Danish Lundenwic: 11 units of peasants with 2 gold chevrons, and silver weapon and gold armour upgrades (Att 17, Def 18)
I wonder where they come from, how they got the experience and the upgrades?
