I was playing the British campaign today and got sick and tired of being raided by the two pirate cities near buy. So, I built up some troops and I went after them. They out numbered me by about 300 troops, but with my troops superior training, cannons, and a good general I managed to beat them with only losing 100 troops. Small problem, after the battle was over I was left outside the city. When I tried to re-enter I noticed that they had all 840 troops left. It was as if I hadn't even tried to take the place. Am I not supposed to go after these guys? Or did I just find a nice new bug? Kind of wasted a couple of hours trying to retake the city a couple of times. Talk about frustrating.
