Battles in Lorraine saw some of the heaviest tank engagements on the Western Front in World War Two, of which the Tank battles of Arracourt are the most famous. The Lorraine Campaign saw two poorly supported armies face each other. The US Third Army was at the end of a successful campaign to liberate France but was now reduced to a secondary role while the Allies prepared for Operation Market Garden. Players use their normal Flames Of War forces to fight battles to capture areas, reinforced by the main combat units shown on the campaign map. Each game the player makes a new force to respond to the situation they face. All of the rules needed to play are included.
