"The rebel fire was very effective and it seemed to us from where we stood that our poor fellows would all get shot. The ground over which they passed was covered with men. We could see them fall in all shapes. Some would fall forward as if they had caught their feet and tripped and fell. Others would stagger about a few paces before they dropped."
Bullets come over frequently to our rear lines, after traveling nearly?one third of a mile. The hum of a spent bullet is very peculiar, often giving timely warning of its approach. The enemy's Coehorn mortar shells, too, are very plentiful today. This is our first experience with them, in any number, while we are within our rear trenches. The enemy fires them high into the air whence they seem to come straight down into the rear trenches, with their threatening "whistle-whistle" - "whistle-whistle," and the final crack and whirr of the pieces.The Confederate army did not have Coehorn mortars at Cold Harbor. Instead they improvised by burying the back ends of some cannon, which elevated the barrel and allowed the cannoneers to lob conventional artillery rounds high into the air. Men on the receiving end -- like the New Hampshire soldier -- probably could not tell the difference.
