Book Description
Do some technologies provoke war? Do others promote peace? Offense-defense theory contends that technological change is an important cause of conflict: leaders will be tempted to launch wars when they believe innovation favors attackers over defenders. Offense-defense theory is perhaps best known from the passionate and intricate debates about first-strike capability and deterrence stability during the cold war, but it has deeper historical roots, remains a staple in international relations theorizing, and drives modern arms control policymaking. In War and the Engineers, the first book systematically to test the logical and empirical validity of offense-defense theory, Keir A. Lieber examines the relationships among politics, technology, and the causes of war. Lieber's cases explore the military and political implications of the spread of railroads, the emergence of rifled small arms and artillery, the introduction of battle tanks, and the nuclear revolution. Lieber incorporates the new historiography of World War I, which draws on archival materials that only recently became available, to challenge many common beliefs about the conflict. The author's central conclusion is that technology is neither a cause of international conflict nor a panacea; instead, power politics remains paramount.

Engineering Victory
Author: Thomas F. Army Jr.
Publisher: JHU Press
ISBN: 1421419386
Category : History
Languages : en
Pages : 384
Book Description
Superior engineering skills among Union soldiers helped ensure victory in the Civil War. Engineering Victory brings a fresh approach to the question of why the North prevailed in the Civil War. Historian Thomas F. Army, Jr., identifies strength in engineering—not superior military strategy or industrial advantage—as the critical determining factor in the war’s outcome. Army finds that Union soldiers were able to apply scientific ingenuity and innovation to complex problems in a way that Confederate soldiers simply could not match. Skilled Free State engineers who were trained during the antebellum period benefited from basic educational reforms, the spread of informal educational practices, and a culture that encouraged learning and innovation. During the war, their rapid construction and repair of roads, railways, and bridges allowed Northern troops to pass quickly through the forbidding terrain of the South as retreating and maneuvering Confederates struggled to cut supply lines and stop the Yankees from pressing any advantage. By presenting detailed case studies from both theaters of the war, Army clearly demonstrates how the soldiers’ education, training, and talents spelled the difference between success and failure, victory and defeat. He also reveals massive logistical operations as critical in determining the war’s outcome.

Engineers of Victory
Author: Paul Kennedy
Publisher: Random House
ISBN: 158836898X
Category : History
Languages : en
Pages : 531
Book Description
NEW YORK TIMES BESTSELLER Paul Kennedy, award-winning author of The Rise and Fall of the Great Powers and one of today’s most renowned historians, now provides a new and unique look at how World War II was won. Engineers of Victory is a fascinating nuts-and-bolts account of the strategic factors that led to Allied victory. Kennedy reveals how the leaders’ grand strategy was carried out by the ordinary soldiers, scientists, engineers, and businessmen responsible for realizing their commanders’ visions of success. In January 1943, FDR and Churchill convened in Casablanca and established the Allied objectives for the war: to defeat the Nazi blitzkrieg; to control the Atlantic sea lanes and the air over western and central Europe; to take the fight to the European mainland; and to end Japan’s imperialism. Astonishingly, a little over a year later, these ambitious goals had nearly all been accomplished. With riveting, tactical detail, Engineers of Victory reveals how. Kennedy recounts the inside stories of the invention of the cavity magnetron, a miniature radar “as small as a soup plate,” and the Hedgehog, a multi-headed grenade launcher that allowed the Allies to overcome the threat to their convoys crossing the Atlantic; the critical decision by engineers to install a super-charged Rolls-Royce engine in the P-51 Mustang, creating a fighter plane more powerful than the Luftwaffe’s; and the innovative use of pontoon bridges (made from rafts strung together) to help Russian troops cross rivers and elude the Nazi blitzkrieg. He takes readers behind the scenes, unveiling exactly how thousands of individual Allied planes and fighting ships were choreographed to collectively pull off the invasion of Normandy, and illuminating how crew chiefs perfected the high-flying and inaccessible B-29 Superfortress that would drop the atomic bombs on Japan. The story of World War II is often told as a grand narrative, as if it were fought by supermen or decided by fate. Here Kennedy uncovers the real heroes of the war, highlighting for the first time the creative strategies, tactics, and organizational decisions that made the lofty Allied objectives into a successful reality. In an even more significant way, Engineers of Victory has another claim to our attention, for it restores “the middle level of war” to its rightful place in history. Praise for Engineers of Victory “Superbly written and carefully documented . . . indispensable reading for anyone who seeks to understand how and why the Allies won.”—The Christian Science Monitor “An important contribution to our understanding of World War II . . . Like an engineer who pries open a pocket watch to reveal its inner mechanics, [Paul] Kennedy tells how little-known men and women at lower levels helped win the war.”—Michael Beschloss, The New York Times Book Review “Histories of World War II tend to concentrate on the leaders and generals at the top who make the big strategic decisions and on the lowly grunts at the bottom. . . . [Engineers of Victory] seeks to fill this gap in the historiography of World War II and does so triumphantly. . . . This book is a fine tribute.”—The Wall Street Journal “[Kennedy] colorfully and convincingly illustrates the ingenuity and persistence of a few men who made all the difference.”—The Washington Post “This superb book is Kennedy’s best.”—Foreign Affairs

Engineering War and Peace in Modern Japan, 1868–1964
Author: Takashi Nishiyama
Publisher: JHU Press
ISBN: 1421412667
Category : History
Languages : en
Pages : 281
Book Description
The role of engineering communities in taking Japan from a defeated war machine into a peacetime technology leader. Naval, aeronautic, and mechanical engineers played a powerful part in the military buildup of Japan in the early and mid-twentieth century. They belonged to a militaristic regime and embraced the importance of their role in it. Takashi Nishiyama examines the impact of war and peace on technological transformation during the twentieth century. He is the first to study the paradoxical and transformative power of Japan’s defeat in World War II through the lens of engineering. Nishiyama asks: How did authorities select and prepare young men to be engineers? How did Japan develop curricula adequate to the task (and from whom did the country borrow)? Under what conditions? What did the engineers think of the planes they built to support Kamikaze suicide missions? But his study ultimately concerns the remarkable transition these trained engineers made after total defeat in 1945. How could the engineers of war machines so quickly turn to peaceful construction projects such as designing the equipment necessary to manufacture consumer products? Most important, they developed new high-speed rail services, including the Shinkansen Bullet Train. What does this change tell us not only about Japan at war and then in peacetime but also about the malleability of engineering cultures? Nishiyama aims to counterbalance prevalent Eurocentric/Americentric views in the history of technology. Engineering War and Peace in Modern Japan, 1868–1964 sets the historical experience of one country’s technological transformation in a larger international framework by studying sources in six different languages: Chinese, English, French, German, Japanese, and Spanish. The result is a fascinating read for those interested in technology, East Asia, and international studies. Nishiyama's work offers lessons to policymakers interested in how a country can recover successfully after defeat.

Engineers at War (Hardcover)

Category : History
Languages : en
Pages : 680
Book Description
NOTE: NO FURTHER DISCOUNT FOR THIS PRINTED PRODUCT- OVERSTOCK SALE -- Significantly reduced list price Engineers at War describes the role of military engineers, especially the U.S. Army Corps of Engineers, in the Vietnam War. It is a story of the engineers' battle against an elusive and determined enemy in one of the harshest underdeveloped regions of the world. Despite these challenges, engineer soldiers successfully carried out their combat and construction missions. The building effort in South Vietnam allowed the United States to deploy and operate a modern 500,000-man force in a far-off region. Although the engineers faced huge construction tasks, they were always ready to support the combat troops. They built ports and depots, carved airfields and airstrips out of jungle and mountain plateaus, repaired roads and bridges, and constructed bases. Because of these efforts, ground combat troops with their supporting engineers were able to fight the enemy from well-established bases. Although most of the construction was temporary, more durable facilities, such as airfields, port and depot complexes, headquarters buildings, communications facilities, and an improved highway system, were intended to serve as economic assets for South Vietnam. This volume covers how the engineers grew from a few advisory detachments to a force of more than 10 percent of the Army troops serving in South Vietnam. The 35th Engineer Group began arriving in large numbers in June 1965 to begin transforming Cam Ranh Bay into a major port, airfield, and depot complex. Within a few years, the Army engineers had expanded to a command, two brigades, six groups, twenty-eight construction and combat battalions, and many smaller units.

Book Description
Curator and space historian at the Smithsonian's National Air and Space Museum delivers a brilliantly nuanced biography of controversial space pioneer Wernher von Braun. Chief rocket engineer of the Third Reich and one of the fathers of the U.S. space program, Wernher von Braun is a source of consistent fascination. Glorified as a visionary and vilified as a war criminal, he was a man of profound moral complexities, whose intelligence and charisma were coupled with an enormous and, some would say, blinding ambition. Based on new sources, Neufeld's biography delivers a meticulously researched and authoritative portrait of the creator of the V-2 rocket and his times, detailing how he was a man caught between morality and progress, between his dreams of the heavens and the earthbound realities of his life.

The Girl Who Could Fix Anything: Beatrice Shilling, World War II Engineer
Author: Mara Rockliff
Publisher: Candlewick Press
ISBN: 1536225673
Category : Juvenile Nonfiction
Languages : en
Pages : 48
Book Description
This true story of a woman whose brilliance and mechanical expertise helped Britain win World War II is sure to inspire STEM readers and fans of amazing women in history. Beatrice Shilling wasn’t quite like other children. She could make anything. She could fix anything. And when she took a thing apart, she put it back together better than before. When Beatrice left home to study engineering, she knew that as a girl she wouldn’t be quite like the other engineers—and she wasn’t. She was better. Still, it took hard work and perseverance to persuade the Royal Aircraft Establishment to give her a chance. But when World War II broke out and British fighter pilots took to the skies in a desperate struggle for survival against Hitler’s bombers, it was clearly time for new ideas. Could Beatrice solve an engine puzzle and help Britain win the war? American author Mara Rockliff and British illustrator Daniel Duncan team up for a fresh look at a turning point in modern history—and the role of a remarkable woman whose ingenuity, persistence, and way with a wrench (or spanner) made her quite unlike anyone else. An author’s note and a list of selective sources provide additional information for curious readers.
