The Civil War was the bloodiest war America has ever faced. In many ways, it was a time of change for the United States. One of these changes was in the technologies that were developed and used. The repeating rifle, the railroad, and the submarine are technologies that were created, tested, or greatly improved during this crisis. This book explores the effect of the war, the impact each technology had on the war and on society in the years and decades following it, and the legacy of these events and developments today.

When America entered World War I, it seemed as though the world had turned upside down. Many new technologies were developed on both sides of this conflict, challenging the men and women who fought in it in ways they never could have imagined. Among these developments were the military tank, the tracer bullet, and most deadly of all, poison gas. This book examines the times and events of the war, the key technologies that influenced and affected it, and the lasting impact these had on global society.

While America did not get involved in World War II until 1941, it saw plenty of combat and new technologies. One of the largest wars in history, World War II provided an opportunity to develop unique and influential technologies such as the jet engine, the computer, and radar. This book unravels the details of the war, the efforts that went into developing these key technologies, and the legacy that the war and these developments had on societies then as well as today.

From 1936 to 1939, the Spanish Civil War ravished a nation. This was a time filled with both suffering and triumph. During it, many inventions were created, improved, or repurposed. This book describes the history behind the conflict and the key innovations that improved or impacted daily life both on and off the battlefield.

The Vietnam War was a conflict that divided many people and brought changes to America. It spanned from the 1950s to the 1970s and saw many new and improved technologies develop—among them napalm, attack helicopters, and TV journalism. These technologies ultimately changed the way people viewed warfare. This is the story of how the war started, what its impact was, and how these technologies changed the face of a nation.

Although previously undervalued for their strategic impact because they represented only a small percentage of total forces, the Union and Confederate navies were crucial to the outcome of the Civil War. In War on the Waters, James M. McPherson has crafted an enlightening, at times harrowing, and ultimately thrilling account of the war's naval campaigns and their military leaders. McPherson recounts how the Union navy's blockade of the Confederate coast, leaky as a sieve in the war's early months, became increasingly effective as it choked off vital imports and exports. Meanwhile, the Confederate navy, dwarfed by its giant adversary, demonstrated daring and military innovation. Commerce raiders sank Union ships and drove the American merchant marine from the high seas. Southern ironclads sent several Union warships to the bottom, naval mines sank many more, and the Confederates deployed the world's first submarine to sink an enemy vessel. But in the end, it was the Union navy that won some of the war's most important strategic victories--as an essential partner to the army on the ground at Fort Donelson, Vicksburg, Port Hudson, Mobile Bay, and Fort Fisher, and all by itself at Port Royal, Fort Henry, New Orleans, and Memphis.

The formation of the Confederate States of America involved more than an attempt to create a new, sovereign nation -- it inspired a flurry of creativity and entrepreneurialism in the South that fiercely matched Union ingenuity. H. Jackson Knight's Confederate Invention brings to light the forgotten history of the Confederacy's industrious inventors and its active patent office. Despite the destruction wrought by the Civil War, evidence of Confederate inventions exists in the registry of the Confederate States Patent Office. Hundreds of southerners submitted applications to the agency to secure patents on their intellectual property, which ranged from a "machine for operating submarine batteries," to a "steam plough," to a "combined knapsack and tent," to an "instrument for sighting cannon." The Confederacy's most successful inventors included entrepreneurs, educators, and military men who sought to develop new weapons, weapon improvements, or other inventions that could benefit the Confederate cause as well as their own lives. Each creation belied the conception of a technologically backward South, incapable of matching the creativity and output of northern counterparts. Knight's work provides a groundbreaking study that includes neglected and largely forgotten patents as well as an array of other primary sources. Details on the patent office's origins, inner workings, and demise, and accounts of southern inventors who obtained patents before, during, and after the war reveal a captivating history recovered from obscurity. A novel creation in its own right, Confederate Invention presents the remarkable story behind the South's long-forgotten Civil War inventors and offers a comprehensive account of Confederate patents.
