I am amazed that as deadly as you would think cannister shot was, charging infantry seemed to have a way of avoiding it. Historically artillery is credited with only causing about 2 to 3% of all casualities. Given battlefield conditions such as visibility, distance and smoke if infantry was close enough for artillery to use cannister shot, the infantryman would be close enough to observe the actions of the artillery crew and would have been aware of when the artillery were ready to fire. I wonder if they (the infantryman) layed down as the artillery fired?
