Man in the iron mask
On  24th August 1669, a man was imprisoned in Pinerolo. Pinerolo was called Pignerol and was part of France at the time. On 19th August, Louvois announced that this prisoner from Dunkerque was a very important person, but that he had not yet been arrested. The prisoner's name was given as Eustache Dauger. In Pinerolo, he met other important prisoners, such as Nicolas Fouquet or Antoine Nompar de Caumont. Dauger was allowed to talk to Fouquet. At times, Daguer acted as a servant to Fouquet, when Fouquet's servant was ill. In 1678, Fouquet asked for more freedom, and this wish was granted. At Fouquet's death in 1680, a hole was discovered between his cell and that of Caumont. From then onwards, both Fouquet's servant and Dauger were separated from Caumont. Both the man with the iron mask, and the servant of Fouquet were transferred to Exilles, which is only  away.
