Battle of the Tollense Valley

There is a Tides of History by Patrick Wyman podcast up about the Battle of Tollense Valley, a remarkable 1996 find in northeastern Germany at a contested causeway on trade routes in an otherwise sparsely-populated area. The find was unexpected and is significant evidence against the idea that Bronze Age northern Europeans were largely peaceful and devoted to trading. Devoted to trading they may well have been.  But that tends to drive both conflict and cooperation, so one cannot assume either.
