An idea I just had about battles, alliences and treachery

[sapi]

Well, here goes....

I was playing rtr the other day, and i got into a battle with me and the armenians vs a rebel town, the trouble being that since the armeniens initiated the siege/assault they'd capture the town despite me outnumbering them 2 to one.

So what i thought would be a good idea is if you could order an attack on your allies units during a siege, and, if you destroyed the entire army with <10 survivors, your dipliomatic status doesn't change, as you can swear that "they did it".

In particular i like the idea of backstabbing an ally in a battle to remove their best army and thus gain the advantage in the war to come.

Ideas/flames?
