0630 19 April 1809
I am returned from Origins and many hours of Kriegsspielling there, and we are off!
One of the toughest things for my 1970's wargame trained brain to remember is that kriegsspiel is event and not turn driven. It isn't necessary to always advance the clock in one hour intervals, rather the clock should advance until something happens. In this case, there weren't a ton of decisions to be made by anyone between 0430 and 0630, so we've jumped two hours.
