A breech-loading cannon is a type of artillery that allows the projectile and propellant to be loaded from the rear, or breech, of the barrel. This design contrasts with muzzle-loading cannons, where ammunition is loaded from the front. Breech-loading cannons enable faster reloading and improved accuracy, making them more effective in battle. These cannons became prominent in the 19th century, significantly influencing military tactics. They were used in various conflicts, including the American Civil War and World War I. The development of breech-loading technology marked a key advancement in artillery design, leading to more powerful and efficient weapons.
