Above a certain count, do the numbers even matter? Well, yes. The difference between the two estimates is large enough to change the way we look at the war. The new estimate suggests that more men died as a result of the Civil War than from all other American wars combined. Approximately 1 in 10 white men of military age in 1860 died from the conflict, a substantial increase from the 1 in 13 implied by the traditional estimate. The death toll is also one of our most important measures of the war’s social and economic costs. A higher death toll, for example, implies that more women were widowed and more children were orphaned as a result of the war than has long been suspected.
In other words, the war touched more lives and communities more deeply than we thought, and thus shaped the course of the ensuing decades of American history in ways we have not yet fully grasped. True, the war was terrible in either case. But just how terrible, and just how extensive its consequences, can only be known when we have a better count of the Civil War dead.
