U-Boats found in the Gulf of Mexico

WWII

World War II era Shipwrecks rest beneath the Gulf of Mexico.

The Robert E. Lee was torpedoed by the U-166 while ferrying victims of other U-boat attacks from Trinidad to New Orleans. The sub succumbed to depth charges fired from an escort ship. These doomed ships are now separated by only two miles of seabed.
Commanding U-166 that July day was Kapitanleutnant Hans-Dieter Heinicke. According to documents from the Monitor National Marine Sanctuary, where the wrecks rest, Heinicke had radioed back to commanders in occupied France on July 13 to say the U-boat was damaged and heading back to Germany after a month-long patrol without success against Allied shipping.
