Several of us reenactors were sitting around a camp fire recently at Chickamauga GA and we were poking fun at some infantry reenactors. Us artillerymen were talking about an old tactic of bouncing a solid shot off the ground and into the legs of an advancing enemy line. Keep in mind that the last line of defense for a Battery of Artillery is to fire "Canister". Canister looks like a giant shotgun shell and contains any where from about 20 to hundreds of 1" steel balls depending on caliber of cannon. One of the Infantry reenactors spoke up and said, The last thing you ever wanted to hear was a battery commander yell to his gun crews; "Range, 100 yards with Double Canister, Load!" Your day was about to get real bad real quick!
There are actual reports of troops turning to run when they advanced close enough to hear the gun commands and heard what was being loaded. Most of the time it was so noisy and so much smoke the infantry couldn't really see how close they had gotten to the guns.
