I'm thinking that the cannon was first spiked (after the fort was captured). The touch hole was "repaired". Then one of two things, the gun crew truly had a bad day or the fort was taken again and the cannon was double or triple charged and shotted and blown up. As our "guide" was to busy getting my tour companions into the cigar bar to make sales and get a kickback I do not have much info on this. Yet, going to look into the history of this fort more later. Yes the cannon is real the carriage is a Bad repro. My thoughts again. Later Tim [ Edited Fri Jun 01 2018, 03:39pm ] | ||

So I'm thinking they were not up to the task. With the size and weight of the cannon it might not have been worth the effort of shipping back to Spain or ? Melting it down and casting into other items, well I'm thinking if this was spiked or blown there were a lot of them and this might have been the only one saved. As we have seen over the years a lot of cannons were used for a lot of different things and repros made also. Saw a lot of repros used on the street corners. "Putting it out of action" is what I'm thinking happened, but could have happened on the original gun crew. One of the times Cuba was again captured as our guide pointed out to us (different location on the tour) was when the US invaded Cuba, after the Maine was blown up that is. US forces or another force British (I believe) took the area and may have disarmed the guns. Where is it? Castillo de los Tres Reyes del Morro, I believe that is correct. In other words the Castle/Fort on the North side of the entrance of the channel into Havana Harbor, Cuba. As I stated before, our guides were more interested in getting the tour group into the cigar shops than talking about the history of the area. The Forts in this area are large. Later Tim | ||

Point blank range was 100 yards, a 24 pounder was capable of sending a ball through a ship at point blank, at 1000 yards it was still capable of inflicting incredible damage particularly if it hits a cannon the shrapnel caused horrendous damage and death. Normally before cannons were "passed" to leave the factory they were test fired several times with charges of 1/2 & 2/3 to 3/4 weight of charge with ball. Cannons were also test fired with a 100% charge without a ball i.e. a 24 pounder had 24 pounds of gunpowder blown off, if any cracks had developed THAT would let them know. The cannons were cast solid it took many weeks to drill the bore and it was not uncommon for a drill to go off centre with devastating consequences when it was tested. Finally, at 1000 yards a 24 pound ball would penetrate 5 feet (thick) of solid dry oak, at point blank 5 feet of solid WET oak and in some cases at 500 yards that's why the lower deck guns favoured the waterline and below. PS. I have a book (in pdf) with the weights of the cannons of various sizes as well as the above info of which I was relying on memory. [ Edited Wed Aug 26 2020, 08:28am ] | ||

Just incredible!! Thanks for sharing Eric. Imagine what the first 128lb shot from the original ironclad Warrior must have been like? No wonder Napolean was so afraid of the British fleet!!! | ||
