That done, Beatrix settled down again, perhaps all the better pleased at finding that by his new treaty obligations Charles had bound himself to proceed immediately to the battle-fields in France. Whether she had a right to be severe upon Charles's little amatory escapades may appear a trifle doubtful by the light of her own conduct now that he was away. At Ghent she took a leaf out of his own book. The duke soon heard of her being in a close _liaison_ with a Polish magnate, Prince Radzivill, _jeune et bien fait, poli et galant_. And not long after arrived the further intelligence that one of her most conspicuous and most successful admirers was our own "gay monarch," Charles Stuart, subsequently Charles II., who was then a refugee in the Netherlands. There is no reason to believe that these misfeasances were in any way belittled to Charles's ear, seeing that it was Princess Marguerite, the Duchess of Orleans, his sister, who played the principal tale-bearer, a lady who, like all the Lorrain princesses, had a direct interest in bringing Charles's connection with Beatrix to a close. Charles took the bait. He was furious with the Princess de Cantecroix. He would repudiate her for good. He would be reconciled on the spot with Nicole. All seemed to herald a happy and creditable ending to the misunderstanding of years, when, all of a sudden, Beatrix announced herself _enceinte_, and by that announcement upset the whole carefully reared-up house of cards. Nicole had borne the duke no son. Here was the prospect of one. Throwing the Pope's warning to the winds, forgetting and forgiving all about Beatrix's wrong-doings, Charles rushed to join her, and was overjoyed to be able to be present at the birth of what was destined to be his only son, Charles, subsequently the gifted and distinguished Prince de Vaudémont, our William III.'s confidant and adviser, and the elder Pretender's potent patron and ally. The Papal Nuncio and the Archbishop of Malines were horrorstruck at this barefaced breaking of a solemn oath. But no serious harm came of it after all. Only, it was a little provoking to find that when the confinement was over, and Charles's back was once more turned, Beatrix calmly resumed her illicit flirtations, of which the Lorrain princesses, more particularly the Princess Marguerite, were not slow to advise the duke.
