The Galloper gun is an artillery piece used circa 1740 in British colonies (later the United States). It has 1½, 2, 3, 4 and rare 6 pound shell variants. The gun and carriage weighs around 600 pounds. The gun was designed to be pulled by one horse between the shafts and to keep up with fast moving troops, perhaps even cavalry.
Gallopers were among the first attempts to give some degree of mobility to guns but the logistics of gun crew movement and ammunition transportation meant that the time to fire from a different location was not significantly reduced.
