The technological advance that contributed most to the Civil War's high casualty rate was a) the minie ball. The minie ball was a conical bullet that was easier to load and more accurate than previous ammunition. Its use in rifled muskets led to devastating injuries and increased lethality on the battlefield, significantly contributing to the high number of casualties during the war.
