A historian believes he's found a number of Third Reich treasures at the bottom of a lake in Poland, including a convoy of Nazi trucks.
Piotr Koper -- who is a Poland native -- has spend more than six months searching the bottom of a lake located in the Polish village of Zarska Wies.
Using sonar and an underwater drone, Koper claims he's found a fleet of trucks once belonging to Adolf Hitler. He also alleges the vehicles contain exhibits from a museum.
Legend has it, Hitler's forces arrived at the reservoir in the winter of 1945 but sunk as they attempted to cross the ice.
The trucks aren't the only items Koper and the “Golden Train Foundation” have found in the water.
They have also allegedly uncovered a lime kiln, tires, and a small case.
"The research was completed on Sunday," Koper told local news site Zgorzelec Nasze Miasto last week.
Speaking about his latest discovery, he stated, “I expect these could be trucks that were sunk in 1945. Today it's hard to say what their value is, because it depends on whether the wrecks are full or empty.”
Koper and his team's work isn't done either.
“We are now waiting for the development of ground-penetrating radar," the historian explained. "If the results are confirmed, we will apply for permission for mining.”
Prior to this search, Koper sent years attempting to track down a Nazi train that was reported to be filled with treasure.
In August 2015, he and historian Andreas Richter claimed they had found it.
According to the duo, the train was located buried in a railway cutting outside of Walbrzych.
But when local authorities got involved, they turned up empty handed.
