The labor and concentration camps are set up already, so you'll have to find the ones you need.
There are prison camps for military already established and the Holocause Project has the concentration camps, death camps, etc covered. I am not sure about civilian prison camps, so I'll need names of them in order to get them added (we have internment camps in WWII as well, but I believe at present there are only scattered additions for Japanese camps).
Some of the others probably won't fit the way we categorize (fighting around places? specific battles are what we do and military units. This isn't Wikipedia).
Others like the bombings can be created, but they need to follow a naming scheme. The Westkapelle one was badly named, so I renamed it included the year as well.
