The Civil War had the most AMERICAN deaths
the most casualties in a war was the American Civil War with 495,332 deaths and behind it is WW2 with 405,399 deaths.
The majority of the deaths in the Civil War came as a result of infection and disease. Many of the young soldiers were being exposed to harmful pathogens carried across the battlefields for the first time in their lives, and therefore had no immunity built to these strains of disease. Additionally, many wounds became quickly infected due to poor conditions, which led eventually to death.
