Artillerymen, I need your help in finding the answer to this question. The Dept. of Georgia Transportation will destroy a Civil War field fort if I can not get a scientific answer to this question. I have done all the background work using primary and secondary sources but the final answer may be in Ordnance reports or test reports on a 10 lbs Parrott gun. I will form this into a question using the OR’s to develop the story problem.
“Union forces just broke through the gap and the first line of Confederate defenses outside the city. This gap is at a 600 ft elevation. The OR reports said they were receiving fire from another Confederate fort that is 1900 yards away. The Union gunners move their 10lbs Parrott guns into the old Confederate defenses that have an elevation of 650 - 680 feet. They are targeting the Confederate fort that is firing at them. It’s at an elevation of 700-730 ft.”
Additional Known Background: There is no evidence of the Union artillerymen firing off the reverse sloop to get higher angle of fire. No trails were dug into the ground to get a higher angle. They have line of sight to target. The OR reports state that the guns fired at 5 degree in elevation. Standard Powder Charge is 1 lb of black powder set a 5 degree elevation. Max range for 10lb Parrott gun is 2,000 yards.
Question: Could the Union guns have hit the target, if they had line of sight, at the gap, with its elevation of 600 ft. If so, where would they hit the target using the elevation scale? The base or the middle of the Confederate fort that is at an elevation of 700 – 730ft?
Could the Union guns hit the target, if they had line of sight, from the old Confederate fort, at the 650 – 680 ft elevation position. If so, where on the target using the elevation scale? The base or the middle of the Confederate fort that is at an elevation of 700 – 730ft?
Things to consider: Muzzle velocity, shell weight, Powder burn rate, Powder temperature, elevation, and Max Ord at 5 degrees.
Any help would possibly save a Civil War field fort from being destroyed.
