I played as Russia once, and they sent everything at kiev. On one bridge battle, there were so many horse corpses that my men were literally fighting waste high in the dead!

The were wearing me down, and I asked for peace. The n00bs refused and attacked again. I killed their king and the faction dissolved, creating a rebel army of 20,000 on one province, Crimea I think.

That's not the funny part, however. The funny thing is that the horde kept on resurfacing and getting killed the very same turn by the ex-horde rebels. This happened 4 times.
