Resting silently on the floor of the English Channel lies a relic of D-Day—a tank that never made it to shore.
When divers discover the remains of an M4 Sherman tank off Omaha Beach, they begin piecing together a remarkable story from June 6, 1944.
Unlike most tanks of World War II, this one wasn't meant to stay on land.
It was a Duplex Drive tank: a specially modified Sherman equipped with a flotation screen and propellers, designed to swim through rough seas and provide armored support during the Normandy invasion.
More than 80 years later, these underwater wrecks remain frozen in time, offering archaeologists and historians a rare glimpse into one of the most ambitious engineering experiments of World War II.
In *War Wrecks: The Lost Tanks of D-Day*, divers investigate these submerged machines and uncover the mystery of why Allied commanders attempted to turn 35-ton tanks into seagoing craft.
On this D-Day anniversary, we remember the courage, sacrifice, and ingenuity that shaped one of history's most important days.
