Randy an I are going to play a campaign around mid July. Using My 6 Page Napoleonics, left side of page bellow.
Wargames Medford Oregon
Here are the main problems i have encountered with campaigns
if supply rules are used the Campaign is usually decided at the map level and no battles are fought.
If fortification rules are used the campaign winds up being sieges
If there is not a minimum size for armies there are lots of stupid battles where an infantry battalion marches on and a cavalry squadron rides around it the whole game.
Attachment is my incomplete preliminary draft of the Map segment of the campaign. If any one wants to check for game breaking mechanisms your feed back is appreciated. I'll be working on this off on on between now and T time.
