Answer: 1) You can use diamonds or gold to redeem your colonized city back from city hall within the 48 hrs since it was being seized.
Gold Redemption: only the city will be back, the officers and remained troops will vanish.
Diamonds Redemption: the city plus all of the officers and remained troops will be back.
2) If you have only one city left, you can\'t redeem it back, system will give you a new city with random location after the only city being seized.
3) If you have two cities and being colonized for both, system will also give you a new city, and the new city can be used as the base to redeem the colonized city, which was seized first, but the second one will be taken by the guy who seized it.
