An epic, riveting history based on new interviews and research that elucidates the approval, construction, and fateful decision to drop the atomic bomb on Hiroshima. At 8:15 a.m. on August 6, 1945, the Japanese port city of Hiroshima was struck by the world’s first atomic bomb. Built in the US by the top-secret Manhattan Project and delivered by a B-29 Superfortress, a revolutionary long-range bomber, the weapon destroyed large swaths of the city, instantly killing tens of thousands. The world would never be the same. The Hiroshima Men ’s vivid narrative recounts the decade-long journey toward this first atomic attack. It charts the race for the bomb during World War II, as the Allies fought the Axis powers, and is told through several key characters: General Leslie Groves, leader of the Manhattan Project alongside Robert Oppenheimer; pioneering Army Air Force pilot Colonel Paul Tibbets Jr.; the mayor of Hiroshima, Senkichi Awaya, who would die alongside eighty thousand fellow citizens; and Pulitzer Prize–winning writer John Hersey, who traveled to Japan for the New Yorker to expose the devastation the bomb inflicted on the city and to describe in unflinching detail the dangers posed by radiation poisoning. This thrilling account takes the reader from the corridors of power in the White House and the Pentagon to the test sites of New Mexico; from the air war above Germany to the Potsdam Conference of Truman, Churchill, and Stalin; from the savage reconquest of the Pacific to the deadly firebombing air raids across Japan. The Hiroshima Men also includes Japanese perspectives—a vital aspect often missing from Western narratives—to complete Iain MacGregor’s nuanced, deeply human account of the bombing’s meaning and aftermath.
