There is a famous Bronze Age battle that took place in what is now northeastern Germany about 3200 years ago. It has been dubbed
The Battle of the Bridge over the Tollense River (that article on SF-Fandom's History blog is a few years old). This ancient battle has inspired many blog posts, forum discussions, and videos.
This is a pretty cool discussion of the battle from a couple of years ago. So if you don't want to read blog articles you may enjoy this presentation from a real-life archaeologist.
