Because you asked for it (oh, and because it was already written) I’ve posted the D-Day Campaigns as a Memoir ’44 Campaign Book Volume I Supplemental (that’s a mouth full!) on BoardGameGeek.com.
The 2 campaigns (US D-Day and UK D-Day) were intended as an introduction to the Campaign rules but for various reasons never got officially published. They can be played with using just the base Memoir ’44 game and a copy of the Campaign Rules (a few of the scenarios in them are available from the Days of Wonder website). Play them together for a mini-grand campaign.
This is a free downloadable PDF. Enjoy!
