How did advances in artillery cause so many casualties

Artillery weapons were substantial cannons that had the ability to fire explosive rounds against enemy positions and lines, which caused a lot of damage to men, landscape, and equipment. Artillery weapons were able to travel far distances which left the sides perform in constant fear of an artillery attack.

Mortality from firearms depends not only on the technology of the weapon or its ammunition but also on the context in which it is used. The increased mortality resulting from the use of firearms in situations other than war requires a complex interaction of factors explicable in terms of wound ballistics and the psychology of the user.
