Significant Civil War Battles
For four straight years, Union and Confederate soldiers battled during the bloodiest war in American history. Both sides suffered unprecedented casualties, and the severe lack of infrastructure made accurate accounting of those soldiers near impossible.
By definition, military "casualties" include not only the dead, but also the injured, ill, captured, and missing. To this day, exact numbers are impossible to determine, and scholars dispute even the most well-researched estimates. However, these staggering numbers still offer profound insight into the immense tragedy experienced by the American people throughout the Civil War.
