I was playing a game last night and taking over towns after bombarding them. I was using artillery to bombard & then cavalry to finish off the infantry defenders after they were down to 1 HP. In my experience I've noticed that sometimes I would be allowed to conquer a city that had been bombarded down to 1 citizen. On other occasions my cavalry would destroy the city. In the past I wondered *WHY* some cities would remain standing for conquering while others were destroyed. It never really mattered that much to me until I conquered a city that had Adam Smith's Trading company in it. Much to my dismay, the city was destroyed and the wonder along with it. So my questions is this: after you bombard a city down to 1 pop point, why are some cities destroyed by my cavalry while others cities remain? Does it have anything to do with how big a city is before the bombarding begins?
