can't get the seleukia reforms...

[Constantine the Great]

The amount of men shouldn't be too impossible. Just >250 on each side.

The difficult parts are > .7 battle odds and that you have to loose 20% of your army and 20% of the leading general's bodyguard. And, of course, loose the battle.

Ah, that's it? Then that should be very achievable. Just lead a stack of levis to the slaughter. Thanks.
