underwater demolition

Underwater demolition refers to the deliberate destruction or neutralization of man-made or natural underwater obstacles, both for military and civilian purposes.Shortly after the American Civil War, Brevet Maj. Gen. John G. Foster, a West Point trained engineer, became one of the first acknowledged experts in underwater demolition. In 1869, he wrote a definitive treatise on the topic and became widely recognized as the authority on underwater demolition. Many of his theories and techniques were still in practice during the Spanish-American War and World War I.
