On the 18th news came that Marechal du Plessis had gained a signal victory over M. de Turenne, who was coming to succour Rhetel, but found it already surrendered to Marechal du Plessis; and the Spanish garrison, endeavouring to retreat, was forced to an engagement on the plains of Saumepuis; that about 2,000 men were killed upon the spot, among the rest a brother of the Elector Palatine, and six colonels, and that there were nearly 4,000 prisoners, the most considerable of whom were several persons of note, and all the colonels, besides twenty colours and eighty-four standards. You may easily guess at the consternation of the Princes’ party; my house was all night filled with the lamentations of despairing mourners, and I found the Duc d’Orleans, as it were, struck dumb.
On the 19th, as I went to the Parliament House, the people looked melancholy, dejected, and frightened out of their wits. The members were afraid to open their mouths, and nobody would mention the name of Mazarin except Menardeau Champre, who spoke of him with encomiums, by giving him the honour of the victory of Rhetel, and then he moved the House to entreat the Queen to put the Princes into the hands of that good and wise Minister, who would be as careful of them as he had been hitherto of the State. I wondered most of all that this man was not hissed in the House, and especially as he passed through the Great Hall. This circumstance, together with what I saw that afternoon in every street, convinced me how much our friends were dispirited, and I therefore resolved next day to raise their courage. I knew the First President to be purblind, and such men greedily swallow every new fact which confirms them in their first impression. I knew likewise the Cardinal to be a man that supposed everybody had a back door. The only way of dealing with men of that stamp is to make them believe that you design to deceive those whom you earnestly endeavour to serve.
For this reason, on the 20th, I declaimed against the disorders of the State, and showed that it having pleased Almighty God to bless his Majesty’s arms and to remove the public enemy from our frontiers by the victory gained over them by Marechal du Plessis, we ought now to apply ourselves seriously to the healing of internal wounds of the State, which are the more dangerous because they are less obvious. To this I thought fit to add that I was obliged to mention the general oppression of the subjects at a time when we had nothing more to fear from the lately routed Spaniards; that, as one of the props of the public safety was the preservation of the royal family, I could not without the utmost concern see the Princes breathe the unwholesome air of Havre-de-Grace, and that I was of opinion that the House should humbly entreat the King to remove them, at least to some place more healthy. At this speech everybody regained their courage and concluded that all was not yet lost. It was observed that the people’s countenances were altered. Those in the Great Hall resumed their former zeal, made the usual acclamations as we went out, and I had that day three hundred carriages of visitors.
