In the middle of World War I, the British ship Laurentic struck two German mines and sank off the stormy coast of Ireland. The ship was carrying 44 tons of gold, a treasure the British needed to finance the war effort. The gold had to be rescued, but how could the British salvage the treasure without alerting the Germans to the undersea booty? In The Sunken Gold, author and naval historian Joseph A. Williams chronicles the seven-year saga of Lieutenant Commander Guybon Damant, who donned a canvas diving suit, the kind with the giant metal helmet, and made it his life mission to recover the gold.
