Who bought the gatling gun in the civil war?

During the Civil War, the Gatling gun was purchased by both the Union and Confederate armies, although the Union made more extensive use of it. The gun was invented by Dr. Richard Gatling, and it was initially sold to the U.S. Army in 1862. Although it was not widely adopted at the time, its unique design allowed for rapid-fire capability, which garnered interest from military leaders on both sides. Ultimately, it became more prominent in later conflicts.
