A Panzer IV tank from the 31st Panzer Regiment, lost in 1940 during World War II, was discovered at the Meuse River thanks to ConeOfArc and their team. Lieutenant Heinz Zobel commanded the tank, which fell into the river during a ferry crossing. The tank, identified as a Panzer IV D, was photographed with a German pioneer infantryman. The soldier’s uniform and equipment suggest he was part of a tank recovery crew. Further investigation by ConeOfArc has revealed more photos of the tank, sparking a debate about its exact location and fate.
