History - Deep Sea Detectives U-Boats In The Gulf

In Summer 1942, with the U.S. at war in Europe and the Pacific, few Americans knew that the war raged in their own backyard. Dozens of Hitler's U-boats had penetrated the Gulf of Mexico, sinking merchant vessels and oil tankers. Of all the U-boats that attacked the Gulf, only one rests at the bottom of the sea--the U-166. Experience the excitement of the first thorough investigation into the wreckage since discovery in 2001 and learn of the technological advances that made its identification possible.
