No, not a Super Soaker; but a squirt gun.
Yep, the squirt gun predates the Civil War if you can believe that.
General William Sherman even used the term squirt gun in a famous quote referring to Lincoln’s call of only 75,000 men as dangerously inadequate saying, “Why, you might as well attempt to put out the flames of a burning house with a squirt-gun.”
The most strategic use for the squirt gun pre-Civil War was used by Squire Boone Jr., Daniel Boone’s brother.
Boone was tasked with defeating the Shawnee tribe in 1778; he managed to convert squirt guns out of rifle barrels which his men used to douse the natives torches.
Pretty genius, this guy was like an eighteenth-century MacGyver.
