G'day chaps the cannon was firing a canister shot containing 30 musket balls to see what the spread and damage would have been against either charging infantry or a gun line. Another shot was against scaffold planking and the balls went through them quite happily and between 12" to 18" into the ground. So we reckon with the width of the pattern and the penetration it would turn about 2 to 3 person width and right through the formation turning the people into tea bags wiith multiple hits on each. A truly horrible weapon to be facing as for the phone ringing it was the person who was filming it on their phone when it rang a bummer but the first time we had fired and filmed the cannon working.
Yours aye,
