Shadow Divers: The True Adventure of Two Americans Who Risked Everything to Solve One of the Last Mysteries of World War II Hardcover – June 29, 2004 by Robert Kurson 
 
In the tradition of Jon Krakauer’s Into Thin Air and Sebastian Junger’s The Perfect Storm comes a true tale of riveting adventure in which two weekend scuba divers risk everything to solve a great historical mystery–and make history themselves.For John Chatterton and Richie Kohler, deep wreck diving was more than a sport. Testing themselves against treacherous currents, braving depths that induced hallucinatory effects, navigating through wreckage as perilous as a minefield, they pushed themselves to their limits and beyond, brushing against death more than once in the rusting hulks of sunken ships.But in the fall of 1991, not even these courageous divers were prepared for what they found 230 feet below the surface, in the frigid Atlantic waters sixty miles off the coast of New Jersey: a World War II German U-boat, its ruined interior a macabre wasteland of twisted metal, tangled wires, and human bones–all buried under decades of accumulated sediment.No identifying marks were visible on the submarine or the few artifacts brought to the surface. No historian, expert, or government had a clue as to which U-boat the men had found. In fact, the official records all agreed that there simply could not be a sunken U-boat and crew at that location.Over the next six years, an elite team of divers embarked on a quest to solve the mystery. Some of them would not live to see its end. Chatterton and Kohler, at first bitter rivals, would be drawn into a friendship that deepened to an almost mystical sense of brotherhood with each other and with the drowned U-boat sailors–former enemies of their country. As the men’s marriages frayed under the pressure of a shared obsession, their dives grew more daring, and each realized that he was hunting more than the identities of a lost U-boat and its nameless crew.Author Robert Kurson’s account of this quest is at once thrilling and emotionally complex, and it is written with a vivid sense of what divers actually experience when they meet the dangers of the ocean’s underworld. The story of Shadow Divers often seems too amazing to be true, but it all happened, two hundred thirty feet down, in the deep blue sea.
 
From The New Yorker
Deep-wreck divers are used to operating with almost no headroom and in zero visibility, navigating by touch alone; it is a compliment to be told "When you die, no one will ever find your body." Despite the dangers, wreck divers are typically weekend warriors, men who leave families and jobs behind to test themselves at two hundred feet down. Kurson's exciting account centers on two divers, John Chatterton and Robert Kohler, who in 1991 found an unidentified U-boat embedded in the ocean floor off the coast of New Jersey. The task of identifying it leads them to Germany, Washington, D.C., and the darkest corners of the submarine itself. Some of the most haunting moments occur on land, as when the divers research the lives of the doomed German sailors whose bones they swim among. Once underwater, Kurson's adrenalized prose sweeps you along in a tale of average-guy adventure.Copyright © 2005 The New Yorker
