There doesn't appear to be a history section on the WON forum so I post here a link to an old account of the campaigns that hopefully is of interest to WON players and players of Campaigns On The Danube (COTD).
I found it intriguing in its use of language in places.

The list of march destinations for the various corps is so like a turn in COTD that it almost seems a source of inspiration for a wargame.
