Relics of a nearly forgotten World War II battle are being explored at the bottom of the sea, not far from Mississippi!
This video comes from the Ocean Exploration Trust. 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 -- as well as what kinds of life have taken shelter in the wreckage.
