States That Suffered the Most Losses in the Civil War

The four-year battle fought between the Union and the Confederacy – the American Civil War – was the deadliest conflict in American history. At the time of war, the country had 37 states, 11 of which had seceded from the Union to form their own "country" called the Confederate States of America. The total losses amounted to around 620,000 soldiers who fought for both the North and the South, including an undetermined amount of women. These are the states that suffered the most losses in the Civil War.

24/7 Tempo collected death toll data from the American Battlefield Trust and historical records by William F. Fox and Frederick H. Dyer, both compiled shortly after the Civil War, to identify and put together a ranking of all states that suffered the most losses in the Civil War. When Fox and Dyer began their research, many death records had already been lost, leading many historians to claim that Civil War fatalities are substantially underestimated. As a result, we opted to use the highest recorded death toll for each state. Information regarding the allegiance of each state during the conflict was also sourced from the American Battlefield Trust.

In its four years, the war resulted in a total of 1.5 million casualties including deaths, injuries, illnesses, imprisonments, and missing persons, with some states sustaining more devastating losses than others.Most Civil War battles occurred in Southern states, despite Union forces suffering higher casualties overall. In at least 10 battles, casualties exceeded 19,000. The Battle of Gettysburg alone saw more American soldiers killed or wounded than the combined toll of the Revolutionary War and the War of 1812.
