Civil War rifles were essential weapons used during the American Civil War (1861-1865). The most common type was the Springfield Model 1861, a muzzle-loading rifle that fired .58 caliber Minie balls. These rifles had improved accuracy and range compared to earlier firearms, allowing soldiers to engage enemies from greater distances. Another notable rifle was the Henry rifle, which was a repeating rifle that could fire multiple rounds without reloading. This innovation provided Union soldiers with a significant advantage in firepower. Overall, the development of these rifles changed the nature of warfare during the Civil War, leading to more deadly and strategic battles.
