I have the idea of creating a map of the "Battle of the Nations" or alternatively also called "Battle of Leipzig" or "Völkerschlacht bei Leipzig" in 1813, where Napoleon was beaten in the biggest battle (about 600.000 soldiers) until the 20th century.
I don't have a real concept so far, but at least roughly in mind, how it should work. I am collecting detailed information to the battle and some maps right now to work out a concept based on that.
I am not able to design a map right now, so I hope there is at least one designer who is interested in helping me with the project. After having a look at the XML-files of other projects, I am sure that I can do that.
