Last Updated by WMHT Web Editor on

Preview A sunken German U-boat off the coast of New Orleans tells the story of Operation Drumbeat.

Watch Wednesday, June 22, 2016 at 9pm on WMHT-TV​

Long before 9/11, a far deadlier, little-known attack from the ocean depths struck our shores, lasting three-and-a-half years and claiming 5,000 lives. Now, famed undersea explorer Bob Ballard, discoverer of the Titanic, investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the gulf just a few miles off New Orleans. U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. With state-of-the-art survey gear, Ballard probes the wreck and explores a dramatic mystery in the official story of the sub’s sinking.
