The German invasion of Western Europe has been going for over a week now, and the Neutral and Allied countries are in disarray. The Netherlands, despite putting up fierce resistance on some occasions, faces overwhelming powers while Belgium, France and the British feel the pressure from an organised and armoured assault from the Ardennes. And still, the German tanks, soldiers and aircraft are not all the Allies have to fear, as many of their losses are caused by their own command.

After the German army breaks through the French lines at Sedan, the left flank of the moving army has to be secured. The French Ouvrage la Ferté, part of the Maginot Line Defense works, is subject to this consolidation. But the Germans move with ulterior motives, as to them capturing a Maginot Line fort in the first week of the offensive has a huge propaganda value. Tour guide Richard Tucker shows Indy the grounds of a modern tragedy, where 107 French soldiers gave their lives.
