Rue de Napoleon was a French road that led from Paris to Versailles. In 1916, Indiana Jones was imprisoned under the name Pierre Blanc — a dead Parisian lieutenant whose identity he had appropriated — at Dusterstadt along the Danube River in Germany. Arriving at a time when the inmates suspected that spies were being placed among them, Jones was questioned by fellow prisoner Charles de Gaulle as he couldn't place "Blanc"'s accent and, since they were both from the French capital, challenged Jones to name the three roads out of the city that led to Versailles. Jones could only name Rue de Napoleon before he struggled but de Gaulle realized that Jones was American and spared the future archaeologist from the officers' anger.
