A few days ago, the battlefield staff at Richmond National Battlefield Park found an artillery shell in Fort Gilmer's moat that had never exploded. This is all kinds of amazing to me... to think that it's been there "unnoticed" for 150 years?! Incredible. The bomb team of the area was called and it was moved and then detonated. It was a 12 pounder, and most likely rolled down the fort's side at Union soldiers. (And if you like history, look up THAT story... fascinating but deadly to the Union troops!) Some people are wondering if it couldn't have been diffused without destroying this piece of history. I don't know enough about the subject to know the answer.
