There’s an archaeological dig getting underway at one of Europe’s most important battlefields: Waterloo in Belgium. That’s where the French Emperor Napoleon Bonaparte was finally defeated in 1815. Among the diggers are two dozen British and Dutch military veterans who are using archaeology to help with their own PTSD. Host Marco Werman speaks with Mark Evans, a former British Army officer and Afghanistan veteran, who co-founded the Waterloo Uncovered organization in 2015.
