Wargaming Campaigns

A long ferry crossing today so a cheeky download for 99p to pass the time on the journey over to France. I'm a big fan of campaigns and have run several at the local club over the years. I've never run a map based campaign, however, and really fancy having a go at a solo effort, perhaps for the One Hour Wargames Hundred Years War project or perhaps the dormant 2mm English Civil War project that I fiddled about with a couple of years ago?
