For over a hundred years, the total number of men killed in the Civil War was thought to be just under 620,000 but new research claims the figure is closer to 750,000. This is a 20% increase on the previous number. Dr David Hacker, a demographic historian, has spent several years trawling through enlistment records trying to calculate an accurate figure to explain past discrepancies. The results of his findings are to be published in a forthcoming book. This is incredibly interesting research, something that will have a massive impact on Civil War studies in the future.
