There have long been secrets buried deep in the southern Appalachians, covered in layers of shale and coal, lying beneath the ancient hills of the Cumberlands, and lurking in the shadow of the Smokies at the tail end of the mountainous spine that ripples down the East Coast. This land of the Cherokee gave way to treaties and settlers and land grants. Newcomers traversed the Cumberland Gap to establish small farms and big lives in a region where alternating ridges and valleys cradle newborn communities in the nooks and crannies of the earth. Isolated. Independent. Hidden.
In 1942, a new secret came to this part of the world. The earth trembled and shook and made way for an unprecedented alliance of military, industrial, and scientific forces, forces that combined to create the most powerful and controversial weapon known to mankind. This weapon released the power present in the great unseen of the time, unleashing the energy of the basic unit of matter known as the atom.
Author H. G. Wells might have called them Sun Snarers, the people who descended upon the valleys and ridges.
“And we know now that the atom, that once we thought hard and impenetrable, and indivisible and final and—lifeless—lifeless, is really a reservoir of immense energy . . . ,” Wells wrote in his 1914 book, The World Set Free. This lesser-known title by the War of the Worlds author describes the harnessing of the power of the nucleus: “And these atomic bombs which science burst upon the world that night were strange even to the men who used them.”
Wells wrote this long before the neutron was discovered, let alone fission, and his work began to popularize the phrase “atomic bombs” before those devices ever took form beyond the author’s pages. But years earlier, people in the mountains claim another prophet lay on the ground, overcome with visions of a project that would bring the snaring of the sun to the hills of Tennessee.
They say a prophet foretold it.
A general oversaw it.
And a team of the world’s greatest scientific minds was tasked with making it all come together.
But it was the others, the great and often unseen, who made the visions of the Prophet and the plans of the General and the theories of the scientists a reality. Tens of thousands of individuals—some still reeling from the Depression, others gripped by anxiety and fear as loved ones fought overseas in the most devastating war any of them had known—worked around the clock on this project, the details of which were not explained. For the young adventurers, male and female, who traveled to Oak Ridge, Tennessee, during World War II, doing their part meant living and working in a secret city, a place created from the ground up for one reason and one reason only—to enrich uranium for the world’s first atomic bomb used in combat.
Roots have always run deep here. They were dug up and scattered when the strangers with the project came to the foothills of the Cumberlands, but the newcomers, too, could not resist the pull of the earth and dug their own roots down deep into the Tennessee clay, soaked by mountain rain and baked by a thousand suns. Permanent. Enduring.
Many of these workers on this secret project hidden in the hills were young women who had left home to fight the war in their own way. They left farms for factories willingly, wrote letters hopefully, waited patiently and worked tirelessly.
A number of these women—and men—still live in Oak Ridge, Tennessee, today. I have had the fascinating and humbling privilege of meeting them, interviewing them, laughing and crying with them and hearing firsthand their tales of life in a secret city while working on a project whose objective was largely kept from them. Over the years they have graciously given me their time and suffered through repeated questions and what must have seemed like insane requests to recall moments from their day-to-day activities roughly 70 years ago. They did so happily and enthusiastically and never, ever with even the slightest bit of bravado. That is not their style. I did not only learn about life on the Manhattan Project. I also found myself taken aback by their sense of adventure and independence, their humility, and their dedication to the preservation of history. I wish I could include each and every one of them in these pages, but I cannot. I hope those who find themselves only in the acknowledgments will accept my thanks in place of my prose. I feel exceptionally lucky to know those who continue to live on, and miss those who have passed since I began working on this book.
Without them, this sun-snaring—this Manhattan Project—would not have achieved its objectives, and because of them a new age was born that would change the world forever.
