John Roebling was one of the 19th century's most brilliant engineers, ingenious inventors, successful manufacturers, and fascinating personalities. Raised in a German backwater amid the war-torn chaos of the Napoleonic Wars, he immigrated to the US in 1831, where he became wealthy and acclaimed, eventually receiving a carte-blanche contract to build one of the 19th century's most stupendous and daring works of engineering: a gigantic suspension bridge to span the East River between New York and Brooklyn.

On April 12, 1862—one year to the day after Confederate guns opened on Fort Sumter and started the Civil War—a tall, mysterious smuggler and self-appointed Union spy named James J. Andrews and 19 infantry volunteers infiltrated Georgia and stole a steam engine called the General. Racing northward at speeds near 60 miles an hour, cutting telegraph lines, and destroying track along the way, Andrews planned to open East Tennessee to the Union army, cutting off men and materiel from the Confederate forces in Virginia.

In 2001, while vacationing on Panama’s Pacific coast, maritime archaeologist James P. Delgado came upon the hulk of a mysterious iron vessel, revealed by the ebbing tides in a small cove at Isla San Telmo. He learned that the wreck was the remains of one of the first successful deep-diving submersibles, built in 1864 by Julius H. Kroehl, an innovator during the Civil War. Delgado chronicles the confluence of technological advancement, entrepreneurial aspiration, American capitalist ambition, and ignorance of the physiological effects of deep diving in this compelling narrative.

On December 18, 1867, the Buffalo and Erie Railroad's eastbound New York Express derailed as it approached the high truss bridge over Big Sister Creek, just east of the small settlement of Angola, New York, on the shores of Lake Erie. The last two cars of the express train were pitched completely off the tracks and plummeted into the creek bed below. When they struck bottom, one of the wrecked cars was immediately engulfed in flames as the heating stoves in the coach spilled out coals and ignited its wooden timbers

This sweeping new history recognizes that the Civil War was not just a military conflict but also a moment of profound transformation in Americans' relationship to the natural world. To be sure, environmental factors such as topography and weather powerfully shaped the outcomes of battles and campaigns, and the war could not have been fought without the horses, cattle, and other animals that were essential to both armies.

Describes the ambivalence of observers that the Civil War was won by automation and mechanization, not heroism and gallantry. Discusses many of the same issues many people have with internet efficiencies conquering many fields and delivering outsized profits with employees being unimportant to the success, profits, and growth of these companies.

Between 1817 and 1898, New York City evolved from a vital Atlantic port of trade to the center of American commerce and culture. Although this important urban transformation is well documented, the critical role of select Union soldiers turned New York engineers has, until now, remained largely unexplored.
