What Weapons were used in the battle of the alamo?
The most effective weapon used in World War I was the machine gun. It was not exactly a new weapon, but this war forced the further development of the weapon. The first fast firing gun was invented in 1862 by a man named Gatling. This rapid-firing weapon was known as the Gatling gun. The first Gatling guns were used in the American Civil War. These guns were rapid-firing, but they depended on the arm of the operator to crank out the bullets.
