I am really enjoying this (well, except for how the saving games works) - but have a question on protecting my hard won cities. I have been working the Swedish intervention (multiple replays and restarts as I learn).
After a siege lasting several months, I finally took Lubeck. But as soon as I left it, Poppenheim comes racing up and takes it immediately. The rules mention garrisons - but he just walked in. How do you stop this?
Do you have to leave a garrison?
Am I supposed to make fortifications?
Do I have to convert enough to make a Garrison show up?
On the subject of sieges, is there a way to do an assault without a breach?
Thanks
