A friend's father told him of a WW1 battle where there was a farmhouse being used by the hunt as an artillery spotting post. The American artillery couldn't come up due to the mud and they had no machine guns, so an officer ranged the farmhouse (wish I had one of those rangefinders) and from about 2000 yards they volley fired. Upon later inspection, they tore the house and it's occupants to shreds.
