Paddy Griffith has asked me to publicise the above forthcoming event. This multiplayer 'crisis game' will be played in the atmospheric surroundings of IWM Duxford on 1st May 2010. Please see the Duxford website for more information: http://duxford.iwm.org.uk/server/show/conEvent.3266
I participated (as an umpire) in the previous such event, which dealt with the invasion of Crete and as such I can highly recommend the game.
I understand from Paddy that there are still several places available. These may include German/British/French and Norwegian roles in command if Land, Air or Naval forces.
