The November 2014 issue of Civil War news contains an interesting article on Confederate countermines at the Siege of Petersburg. The mining and countermining operations at Petersburg, with the exception of the 48th Pennsylvania’s famous mine which led to the Battle of the Crater, are largely unknown. Did you know, for instance, of a Confederate attempt on August 5, 1864 to blow up what would become Fort Stedman, or at the very least disrupt potential Union mining operations in the area? It’s a fascinating angle, and I wish more was known in this area. In any event, go check the article out. I think you’ll find it interesting and you may learn something new.
