Relics of a nearly forgotten WWII battle are being explored at the bottom of the sea, not far from Mississippi.
The Ocean Exploration Trust is performing the exploration. Their robotic underwater cameras are checking out the wreckage of a German U-Boat, a type of submarine, and an American warship, the Robert E Lee.
The nazi crew aboard U-166
sank the Lee in the Gulf of Mexico some 72 years ago.
Scientists hope to learn more about how the ships sank. They are also investigating what kinds of life have taken shelter in the wreckage.
