it is my pleasure to introduce kevin pollak. [applause] kevin: good morning. thank you to chris for that very humbling introduction and thank you all for being here at my bachelor party. [laughter] i think we might set a virginia state record for the largest party and virginia state history. it is about to get crazy talking about robert e. lee at the battle of antietam. even last year at the symposium when an email was sent out there was aopics, caveat left in the email that allowed us to quote " think outside the box." the topic i'm proposing, robert e. lee at antietam, i thought that was going to be a very straightforward presentation about a great defense of the civil war. looking into it, there is a bit more to robert e. lee's defensed and what we have thought. as human beings, we are always products of the past. as history buffs, people who love to study the american civil war, we are always reading and looking again to what historians before us had said. what i'm going to ask you to do now is for the next 45 minutes, forget everything you have ever heard
