Hi everybody, I'm not so used with this forum, so I don't know if I'm asking my question in the right place. If not, please don't kill me. 
Anyway, I'm currently playing a 16-civ-random map with C3C, with "Capture the princess" mode on. I've already defeated French and Othmans, but... I didn't managed to capture their Princesses!
I mean, I read on the Civilopedia that I should look for a "Capture" action, but I can't find the button / keyboard shortcut / whatever.
Where can I find it? Or which unit I should use to capture that bi... units?
Or have I lost forever that - precious - 2.000 Victory Points?
Thank you very much.
