This is a module of Avalon Hill Game Company's hex'n'counter wargame D-Day - Smithsonian Edition, developed in collaboration with the Smithsonian Institute for their American History series (VASSAL modules). It is derived from AHGC's more advanced game D-Day (VASSAL module and Print'n'Play versions).

These module features

  • Rules in the Help menu
  • A tutorial (to come)
  • Automatic battle and odds markers
  • Automatic combat resolution and result markers
  • Reminders on user actions
  • (Semi-) Historical set-up
  • Two scenarios, actual 1944 invasion and early 1943 invasion (separate modules)

Concerning combats

  • Select attacking and defending units, and press Odds (Ctrl-Y) button
    • Adds battle markers
    • Calculates odds, including terrain and ground condition effects, and adds marker
  • Select odds marker and select Resolve (Ctrl-X) from context menu
    • Rolls dice and looks up result
    • Replaces odds marker with result marker
  • Factions must implement the result (retreats,losses,etc.)

See also the Help->More information for more.

See also the sister game Battle of the Bulge - Smithsonian Edition, available as a VASSAL module and as a Print'n'Play (to come) PDF.


  • Use the turn track in the menu bar. It implements some automatic actions, and progresses the turn marker along the turn track.
  • Battle markers and automatic battle resolution.
  • On game start, select optional rules to use. Will be locked thereafter.
  • The rules are available, as a PDF, through the Help menu.
  • See also More information in the Help menu.
  • Run the tutorial (when it becomes available :-)


This module is based on my version of the game (sources available from this site). This version a revamp of the original, including new text and graphics, written in LaTeX using wargame package. This package supports generating a (draft) VASSAL module from the same sources as the Print'n'Play PDF.
