Richard Gatling wrote to a friend in 1877:
“It occurred to me that if I could invent a machine – a gun – which could by its rapidity of fire, enable one man to do as much battle duty as a hundred, that it would, to a great extent supersede the necessity of large armies, and consequently, exposure to battle and disease [would be] greatly diminished.”
Gatling was the inventor behind the first successful machine gun.
The Gatling gun changed history, and the way wars were fought forever.
