I joined this site, just to make this post. I have read the site and enjoy the comments. See the pictures attached of a part of a cannon that my family has had for some time. I will tell the story, and I am hoping to find out any information that anyone may have. As you can see it is the trunnion of a cannon still attached to the outer bore and a small section of the inner bore. It has the markings "1820" on the trunnion. I am assuming that is the year / model number of the cannon. This piece of cannon was found by my father and grandfather in the mid to late 1960's, just below Fort Pillow down the bluff a ways (probably less than 100 yards or so). They were able to keep the cannon because at that time it was private land and not a historic park. I have always wondered why it appears that it was exploded. Years ago, someone told us that a few years after the war, there was a 4th of July celebration at the fort and two cannons were shot off. One of them exploded and killed a few folks. That has always been what we assumed happened, but I have researched that and found nothing. I just don't think that sounds right. I would love to learn any information about the model of cannon, size of cannon, and how it may have exploded. the diameter of the trunnion is 6.25" across. The entire piece is extremely heavy. Once person cant barely lift it 1 inch of the ground. Thanks for any responses.
