Neat video purporting to be a science experiment on determining the position of artillery on preserved battlefields, but there’s less science on display than yeehawing reenactors and buffs getting to shoot live ammunition from a Napoleon cannon.
Seeing the grapeshot’s range and scatter disquieting. I am amazed anew at the bravery of the men who marched willingly into the face of that threat. Hearing that peculiar jangling noise as you marched within range must have been terrifying.
