The Gatling gun is a rapid-firing multi-barrel firearm invented in 1861 and named after its inventor: Dr. Richard Jordan Gatling. It is considered a forerunner of the modern electric motor-driven cannon.

The Gatling gun is one of the most famous of the early rapid-fire firearms, largely due to its association with Union forces during the American Civil War, which was the first war in which it was employed in combat. It should be noted that even though the Gatling gun was invented the same year as the start of that war, the Gatling gun was not in widespread use during the American civil war.

In 1870, Dr. Gatling sold his Gatling gun patents to Colt, but remained president of the Gatling Gun Company until it was fully absorbed by Colt in 1897. In 1893, he patented a Gatling gun that had an electric motor instead of the hand-crank and could fire 3,000 rounds per minute.

Gatling Gun


The Gatlin gun had a cyclic multi-barrel design.

As the handwheel was cranked, the barrels would rotate. Each barrel sequentially loaded a single cartridge from a top-mounted magazine, fired off the shot when it reached a set position (typically 4 o´clock), and ejected the spent casing out of the left-hand side at the bottom. Once the barrel was empty, it was given sufficient time to cool before the rotation brought it back to the top position where it was gravity-fed another round.

Inventing the Gatling gun

After the outbreak of the American Civil War in April of 1861, the inventor Dr. Richard J. Gatling in Indianapolis devoted himself to the creation of a new firearm, and the Gatling gun was the result. He patented it in November 1861 and founded the Gatling Gun Company the following year.

He wrote that he created it to reduce the size of armies and thereby reduce the number of deaths by combat and disease, and also to show how futile war is. He had noticed that a majority of the soldiers dying the in Civil War died from disease, not from gunshots.

It occurred to me that if I could invent a machine 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 large extent supersede the necessity of large armies, and consequently, exposure to battle and disease would be greatly diminished.” – Dr. Gatling in 1877

When designing the Gatling gun, Dr. Gatling was inspired by how his seed planter worked.

Production and early sales

  • The first prototype was finished in 1861.
  • The first six production guns were destroyed during a fire in the factory in December 1862. All of them had been manufactured at Gatling´s own expense. After the fire, he commissioned another 13 to be manufactured at the Cincinnati Type Factory.
  • General Benjamin F. Butler purchased 12 Gatlin guns and Admiral David Dixon Porter bought one.
  • In 1866, the United States government officially bought their first Gatling guns. (The American Civil War ended in 1865.)
