Our house sits on Banner Hill, looking out over Smith's Cove and Gloucester Harbor. It's called Banner Hill because some locals raised a flag there at the outbreak of the Civil War. And so we wondered, when we moved in some 15 years ago, if perhaps this cannon we found in the basement dated back to the 1860s and had been unearthed when the house's foundation was dug. We contacted the local historical society and sent them photos. They never replied.
