New Estimate Raises Civil War Death Toll (Published 2012) (2024)

For 110 years, the numbers stood as gospel: 618,222 men died in the Civil War, 360,222 from the North and 258,000 from the South — by far the greatest toll of any war in American history.

But new research shows that the numbers were far too low.

By combing through newly digitized census data from the 19th century, J. David Hacker, a demographic historian from Binghamton University in New York, has recalculated the death toll and increased it by more than 20 percent — to 750,000.

The new figure is already winning acceptance from scholars. Civil War History, the journal that published Dr. Hacker’s paper, called it “among the most consequential pieces ever to appear” in its pages. And a pre-eminent authority on the era, Eric Foner, a historian at Columbia University, said:

“It even further elevates the significance of the Civil War and makes a dramatic statement about how the war is a central moment in American history. It helps you understand, particularly in the South with a much smaller population, what a devastating experience this was.”

The old figure dates back well over a century, the work of two Union Army veterans who were passionate amateur historians: William F. Fox and Thomas Leonard Livermore.

Fox, who had fought at Antietam, Chancellorsville and Gettysburg, knew well the horrors of the Civil War. He did his research the hard way, reading every muster list, battlefield report and pension record he could find.

In his 1889 treatise “Regimental Losses in the American Civil War, 1861-1865,” Fox presented an immense mass of information. Besides the aggregate death count, researchers could learn that the Fifth New Hampshire lost more soldiers (295 killed) than any other Union regiment; that Gettysburg and Waterloo were almost equivalent battles, with each of the four combatant armies suffering about 23,000 casualties; that the Union Army had 166 regiments of black troops; and that the average Union soldier was 5 feet 8 1/4 inches tall and weighed 143 1/2 pounds.
