Can someone explain to me how to pull this off? I know I want to support a revolt, and i have plenty of EPs to do just that. The question is, do I do it and attack the city on the same turn, or does it take a turn to take effect? The situation that has this coming up: playing Pericles, Standard size, Marathon, Prince. I have a major intercontinental invasion about to begin, using Cannon, Rifles and Calvary vs pre-industrial defenses. I am going for a cultural victory, but Justinian has far too much space and manufacturing capability to allow him to continue unimpeded, and his neighbors have been unable to counterbalance his power. So I am planning to seize 3 of his key cities as fast and bloodlessly as is humanly possible, and hopefully reduce him to a vassal in short order. The image is listing the defenses of Constantinople, which are about equivalent to the two other cities. (And yes, I know I can win this battle without using the espionage, but I want to keep my army as intact as possible, as his navy is far superior to mine and the chances of quick, significant reinforcements are nil.
