Sinking of the Lusitania terror at sea

Summary: On May 7, 1915, the passenger ship Lusitania was en route to England from New York City when a torpedo from a German U-boat sent the luxury liner and more than 1,000 passengers to an icy grave. The sinking of this great ocean liner shocked the world and "Avenge the Lusitania!" was the rallying cry that lured many young American men to enlist during World War I. In this dramatic special, Discovery Channel brings you the story of the doomed ship and, for the first time, goes inside the cramped, foul-smelling hull of the U-boat that fired the fateful torpedo.
