The American Civil War resulted in approximately 620,000 to 750,000 casualties. In comparison, the combined casualties of World War I (around 116,516 U.S. military deaths), the Korean War (approximately 36,574 U.S. military deaths), the Vietnam War (about 58,220 U.S. military deaths), and the Gulf War (around 294 U.S. military deaths) do not exceed the Civil War's total. This illustrates the immense scale of loss during the Civil War compared to these more recent conflicts.
