|On a fortified hill called Burnswark in Scotland some 1,900 years ago a Roman army attacked local warriors by hurling lead bullets from slings that had nearly the stopping power of a modern .44 magnum handgun, according to experts. The assault must have been deadly effective, but Burnswark was just the opening salvo in a war against the tribes living north of Hadrian’s Wall. Despite their superior weaponry, Roman soldiers fought a tough, resourceful enemy capable of melting away into the hills and marshes.|
Less than two decades after the Romans attacked Burnswark, they retreated south to Hadrian’s Wall.
Roman soldiers armed with slings used lead bullets to mow down foes.
Archaeologists also discovered two ballista balls
