Overview:
Today, the evolution of man's ability to strike from beneath the waves is moving toward its full potential. The two vessels that started us on this evolutionary path were the first underwater warriors and the first of their kind to seek enemy ships in battle. They were Germany's U-21, a gray wolf which drew first blood during the opening days of the First World War; and the extraordinary underwater fighting ship wielded and lost by the Confederacy during the American Civil War, the legendary HL Hunley. These two vessels mark important turning points in the evolution of the modern submarine. And both have gone down in history as the vessels that got the first kill.
