Translations for confirmation in French

Here are paragraphs from public domain books translated:

“But it was some time coming. The old gentleman could not be decoyed outside of his grounds at night. Several times Stapleton lurked about with his hound, but without avail. It was during these fruitless quests that he, or rather his ally, was seen by peasants, and that the legend of the demon dog received a new confirmation. He had hoped that his wife might lure Sir Charles to his ruin, but here she proved unexpectedly independent. She would not endeavour to entangle the old gentleman in a sentimental attachment which might deliver him over to his enemy. Threats and even, I am sorry to say, blows refused to move her. She would have nothing to do with it, and for a time Stapleton was at a deadlock.

« Elle ne se présenta pas immédiatement. Impossible d’attirer, la nuit, le vieux gentilhomme hors de chez lui. Plusieurs fois, Stapleton rôda dans les environs, accompagné de son chien — mais sans succès. Ce fut pendant ces infructueuses tournées que des paysans aperçurent son terrible allié et que la légende du chien-démon reçut une nouvelle confirmation. « Il avait espéré que sa femme le seconderait dans ses projets contre sir Charles, mais elle s’y refusa énergiquement. Elle ne voulait pas entraîner le vieux gentilhomme dans un commerce sentimental qui le livrerait sans défense à son ennemi. Les menaces et même les coups — je suis honteux de le dire — ne purent briser la résistance de la la pauvre femme. Elle s’obstina à ne se mêler de rien, et Stapleton se trouva fort embarrassé.
