We would have to make this extensive to rebel captures but...

In one of my Turkish campaigns, i deicded not to face the Horde, so i, who was in control of Khazar, simply backed off before they came.

1230, the Horde comes, the Khan dies!(How?? i don't know, and i didn't really care)

so, by 1231 i send a Jihad... well, more like 20 Jihads and 2 full stacks, to reconquer Khazar. To my surprise, the rebels decided to let me "go through" without resistance.

The outcome of all that was: 18000 soldiers captures, for a total of 96,000 florins... i released them all for showing true piety

Other than that, a couple king ransoms for 15k... that's it
