In RTW, a revolt throws the garrison out on it's rear, but the garrison is still intact, and usually with the same manning that was there when the revolt occured, example,

Revolt

Your Citizens Killed, 4,329
Your Soldiers Killed, 0

and the units that were there inside the city, are just outside of it. I usually besiege it immediately, and depending upon what the enemy has inside, wait till they surrender, or attack.

It used to be the same way in BI most of the time. Once in a while the purple units would simply turn green, but more often than not, the purple or red army would simply be thrown out.

I think that installing the 1.6 patch in may have had something to do with it.

As for transporting them out of range of the besieging army, it doesn't happen, but as I see it, if a revolt throws them out the gate, and the besieging army goes in, the too weak garrison can try to escape to a stronger point.

That has happened in history. I'd hoped to pull it off. So far, it hasn't worked in BI, but it has worked in RTW. But with RTW, I seldom have a city not strong enough to defend itself.
