It was ridiculous to ascribe any intense desire on the part of the Duc de Bouillon to aid the Protestant cause against Spain at that moment, acting as he was in combination with Conde, whom we have just seen employed by Spain as the chief instrument to effect the destruction of France and the bastardy of the Queen's children. Nor did the sincere and devout Protestants who had clung to the cause through good and bad report, men like Duplessis-Mornay, for example, and those who usually acted with him, believe in any of these schemes for partitioning France on pretence of saving Protestantism. But Bouillon, greatest of all French fishermen in troubled waters, was brother-in-law of Prince Maurice of Nassau, and Aerssens instinctively felt that the time had come when he should anchor himself to firm holding ground at home. The Ambassador had also a personal grievance. Many of his most secret despatches to the States-General in which he expressed himself very freely, forcibly, and accurately on the general situation in France, especially in regard to the Spanish marriages and the Treaty of Hampton Court, had been transcribed at the Hague and copies of them sent to the French government. No baser act of treachery to an envoy could be imagined. It was not surprising that Aerssens complained bitterly of the deed. He secretly suspected Barneveld, but with injustice, of having played him this evil turn, and the incident first planted the seeds of the deadly hatred which was to bear such fatal fruit.
