Somewhere in Virginia lies Mosby's sack
In 1863, Confederate ranger John Singleton Mosby and his band of guerrilla raiders were able to sneak ten miles into Union territory and capture more than 40 Union troops at the Fairfax, Virginia Courthouse—all without firing a single shot. Mosby reportedly left with a burlap sack stuffed with what was then valued $350,000 worth in gold, silver, jewelry, candlesticks, and other family heirlooms, all of them taken from the homes of local plantation owners. On the way back to the Confederate line, Mosby was warned that Union soldiers were nearby and opted to bury the sack between two trees, marking the spot with his knife. Later, he sent seven of his men back to retrieve it, but they were captured and executed. As far as we know, Mosby never went back, so the loot could still be out there.
