Previously recorded fate (Last revised by uboat.net during June 2001)
Sunk on 1 August, 1942 in the Gulf of Mexico, in position 28.37N, 90.45W, by a single depth charge from a US J4F-1 Grumman aircraft (USCG V-212/Y).
This may have been an attack on U-171.
The discovery of U-166 (June 10, 2001)
This boat was finally discovered and documented in late May 2001 after years and years of unsuccessful research and wreck-hunting. The wreck was located some 45 miles south of the mouth of Mississippi River, by C & C Technologies with their AUV during oil-survey work for BP Amoco and Shell.
We're compiling an article on the loss and eventual discovery of the boat right now, should be ready in the next few days.
Its discovery also changes its official fate since it's now certain that she was lost right after sinking her fourth and last victim, Robert E. Lee on July 30, 1942. Their wrecks are less than one mile from each other.
She is of course a gravesite now and cannot be disturbed, she is protected by some 5000feet of water in this regard.
uboat.net had published a theory on its location for a long time and that theory was proven correct although most did not subscribe to that one
