We've got a good crew taking up this week. All-star commenter Andy Hall is going to fill in. Andy's knowledge of all things Civil War is truly intimidating. Also Mark Kleiman author of When Brute Force Fails will join us. Lastly, we have Neil Drumming who's done several stints here before. I think it will be a pretty awesome week.
