I found this video on youtube. It is of a Volley and Bayonet American Revolutionary War game run at Historicon 2010. Based on the voices in the background, it was the one run by Greg Novak (I wasn’t there as I am a West Coast guy who avoids crossing the Mississippi if possible). It gives you a good idea of what VnB looks like in action. See http://www.youtube.com/watch?v=NBEKbZ1nIto.
