Artillery Round Question

[huntdaw]

The library here in New Madrid has a large solid shot mounted at the base of a flag pole. It was recovered from here and is an artifact of the Island #10/Siege of New Madrid operation in early 1862.

I am trying to figure out what fired it. We had ironclad gunboats, mortar boats, siege guns, floating batteries and field pieces all throwing iron around here.

It is a solid shot and has a circumference of 47 inches. That's really all there is to it but I don't know enough about big guns to know what may have fired this thing. Any help much appreciated.

The platforms sturdy enough to fire a 15 inch solid shot around the Cape Fear mounted Columbiads and Rodmans. I dont know of any mortars flinging solid shot here. That's no help because you have already listed those guns that would do the trick (...ironclad gunboats, mortar boats... floating batteries...)

[Marine Mike]

Columbiad is a style invented about the War of 1812 and Rodman is a design. 15 inch solid shot should weigh about 400 lbs. 15 inch Rodman dates from 1861. Dahlgren completes his design in April 1862. Battle of Island #10 concludes April 8 1862. Narrows things down a bit. I'm not aware of mortar shooting solid shot. I believe they only shot exploding shell.

Typically you see artillery shells listed by diameter or weight. If you have either of those you should be able to figure it out. Here are a couple of sources that may help:

Good luck!

Circumference=2(pi)R

47/6.28=R
7.48=R

R2=D

14.96=D

Your shot was fired from a 15 inch something or other. Most likley not a morter. Although solid shot could be fired from morters and was made for them, it was rarely used.

R2=D

I hope the hell there isn't a test on this.

After the Armstrong gun was disabled, USN ironclads in the channel off Fisher could paddle in close and shoot the heavy guns directly on the waterline. The damn things would skip across the surface, up the beach and bound the ditches before plowing through anything unfortunate enough to be in the way.

Forgive me my Google.

Yep, that's the round in question at the base of the flagpole. I've been checking on the armament that was available and haven't found anything that specifically says there was a 15" piece. There are some guns the Confederates had at Island #10 (where this solid shot was recovered) that are listed as heavy artillery. I can only deduce that one of those guns shot this thing but I was hoping to really narrow it down to a specific type. I'll continue the search and appreciate everyone's input so far.

[Southron Sanders, Sr.,]

Are you absolutely, positively sure it is SOLID SHOT? If not, then it probably still has its original bursting charge inside of it and it needs to be disarmed.

IF it is a solid shot, sometimes they were heated red hot in a furnace and then fired at enemy ships. Is there any record of Confederates firing "Hot Shot" at the Union vessels? Is there any indication that there was a furnace on Island No. 10? Any record of the Union vessels firing "Hot Shot" at Island No. 10?

Most references I've found mention 8 inchers, 32 pounders(rifled and smooth) and 64 pound howitzers. One account does mention the firing during the gunboat attack of a 128 pounder, called the "Lady Polk, Jr." which could be your culprit.
