On January 25, 1917, HMS Laurentic struck two German mines off the coast of Ireland and sank. The ship was carrying 44 tons of gold bullion to the still-neutral United States via Canada in order to finance the war effort for Britain and its allies. Britain desperately needed that sunken treasure, but any salvage had to be secret since the British government dared not alert the Germans to the presence of the gold.

Lieutenant Commander Guybon Damant was the most qualified officer to head the risky mission. Wild gales battered the wreck into the shape of an accordion, turning the operation into a multiyear struggle of man versus nature. As the war raged on, Damant was called off the salvage to lead a team of covert divers to investigate and search through the contents of recently sunk U-boats for ciphers, minefield schematics, and other secrets. The information they obtained, once in the hands of British intelligence, proved critical toward Allied efforts to defeat the U-boats and win the war.

But Damant had become obsessed with completing his long-deferred mission. His team struggled for five more years as it became apparent that the work could only be accomplished by muscle, grit, and persistence. Using newly discovered sources, author Joseph A. Williams provides the first full-length account of the quest for the Laurentic's gold. More than an incredible story about undersea diving adventure, The Sunken Gold is a story of human persistence, bravery, and patriotism.
