Clive Cussler's The Sea Hunters Season 1 Episode 11 The Hunley - The First Kill

Two historic shipwrecks, separated by five decades and resting hundreds of kilometres apart, tell the tale of man's newfound ability to strike at his enemies from beneath the sea. The Sea Hunters search for the remains of two vessels that introduced submarine warfare to the world; Germany's U-21 which drew first blood in the early days of the First World War; and the H. L. Hunley.
