69: Drew Gilpin Faust's This Republic of Suffering

In This Republic of Suffering: Death and the American Civil War, Drew Gilpin Faust uses a wide variety of primary materials to understand the cultural implications of the Civil War.  Working from correspondence between soldiers and their families and friends; poetry and writings by Emily Dickinson, Walt Whitman, Ambrose Bierce, and others; and the voices of the legions of relief workers, coffin manufacturers, government bureaucrats, and other support staff, Faust shows new processes of dying and killing, along with new ways of making sense of these processes, helped shift the nation from a relatively unstructured agrarian federation to a modern, centralized, bureaucratic, industrial state.

The Civil War produced some 620,000 dead, which made death not just one of many features of the war but the defining element of it.  The sheer mass of bodies, generated by the combination of old styles of warfare with new, technologically-enhanced ways of killing, created huge logistical issues.  Soldiers died in new and gruesome ways, which made identification difficult; but even if they didn't, there was still the problem of mitigating bodily decay while trying to identify thousands of bodies and return them to their families.  These new problems generated new social and technological systems: refrigerated coffins, new embalming practices, streamlined accounting methods, and new bureaucratic systems to oversee the sheer volume of bodies needing to be processed.  Dealing with death thus helped businesses and the nation develop more modern systems for mass production and distribution.
