A Nazi U-boat and the merchant ship it sank off the US coast in 1942 have been found at the bottom of the Atlantic.
The freighter Bluefields and U-576 came to rest just 240 yards (220 metres) apart in the aptly named "Graveyard of the Atlantic".
The two ships squared off on 15 July 1942 when the Nazi sub came upon a 19-ship convoy about 30 miles (48km) off the coast of North Carolina.
They were rediscovered on 30 August by researchers from the National Oceanic and Atmospheric Administration (NOAA).
"That whole battlefield scene is there. Both sides of the story are represented as a memorial to history" NOAA chief scientist Joe Hoyt said.
The U-boat's commander, Kapitanleutnant Hans-Dieter Heinicke, was heading back to Germany for much-needed repairs but decided to attack the convoy despite the ship's damages.
U-576 launched four torpedoes, one of which struck the Nicaraguan-flagged Bluefields, sinking the 261ft (79m) freighter in minutes. Two other ships were also hit, but managed to stay afloat.
US aircraft attached to a nearby military escort group bombed the U-boat as it surfaced, sending it to the bottom of the Atlantic.
All 45 men aboard U-576 died and are believed entombed in the wreck 700ft (213m) below the surface.
No one on board the Bluefields was killed in the battle.
The NOAA delayed releasing information about the discovery to give the German government time to track down and notify any survivors of the U-boat crew, Mr Hoyt said.
In a statement provided to the NOAA, the German foreign office asked the US to view the wreck as a war grave.
"As such, they are under special protection and should, if possible, remain at their site and location to allow the dead to rest in peace," the statement said.
The NOAA and the Bureau of Ocean Energy Management began working together in 2008 to find vessels lost off the North Carolina coast during World War II.
The wrecks of three other U-boats sit in more shallow waters off the coast. Several of the Nazi subs were scuttled as WWII came to a close.
