I think you’re referring to the Berlin subway incident. In a recent post it was revealed that near the end of the Battle of Berlin the tunnels were packed by civilians, mostly women and children, taking refuge. Some SS wanted to use a tunnel for moving troops but the people begged them to stop the fighting instead. They packed explosives by where the tunnel was close to the Spree River and blew it, flooding the tunnel.
“...flooding the tunnel.”
Yes - thank you. Pretty sad when I can’t remember stuff like that from just a few days ago. Although I did get the gist of it I guess. Those Nazi’s and Japs were bad news.
