I'm looking for reliable studies on the number of casualties caused by artillery in Napoleonic times. There are many eyewitness accounts of the horrific effects on the massed columns, and even estimates on how far could the roundshot "penetrate" rows of men, but no estimates on the number of dead or wounded.

My own data refers only to the wounded by artillery fire (all types) during the Peninsular War: 8% vs 80% musket fire and 12% steel (sample of 3,868 French officers). But unfortunately nothing on the cause of death. Any ideas about where to look?
