The American Civil War is a pivotal and ugly moment in American history, but it's more misunderstood than you would think. Tensions between the two leaders came to an ugly head during the Civil War Draft Riots of 1863. Plenty of Civil War movies show screaming soldiers having their mangled limbs amputated with hacksaws in a medical tent while wide awake. But despite what Hollywood says, anesthesia is estimated to have been used in around 95 percent of all surgeries during the war, according to the National Museum of Civil War Medicine. Misconception: The war was fought entirely in the U.S.Gettysburg is, perhaps, the classic vision of a Civil War battlefield: green, hilly fields ensconced in artillery smoke.
