Translations for treaty in French

Here are paragraphs from public domain books translated:

The explosion of disapproval, which nothing but Silver's black looks had restrained, broke out immediately the doctor had left the house. Silver was roundly accused of playing double—of trying to make a separate peace for himself—of sacrificing the interests of his accomplices and victims; and, in one word, of the identical, exact thing that he was doing. It seemed to me so obvious, in this case, that I could not imagine how he was to turn their anger. But he was twice the man the rest were, and his last night's victory had given him a huge preponderance on their minds. He called them all the fools and dolts you can imagine, said it was necessary I should talk to the doctor, fluttered the chart in their faces, asked them if they could afford to break the treaty the very day they were bound a-treasure-hunting.

Les récriminations unanimes que contenaient seuls les regards menaçants de Silver éclatèrent aussitôt que le docteur eut quitté la maison. Silver fut carrément accusé de jouer double jeu, d’essayer de conclure sa paix séparée, de sacrifier les intérêts de ses complices et victimes ; on l’accusa, en un mot, exactement de ce qu’il faisait. Sa trahison, dans le cas actuel, me parut si évidente que je me demandai comment il allait détourner leur colère. Mais cet homme valait à lui seul deux fois tous les autres réunis, et sa victoire de la nuit précédente lui avait rendu à leurs yeux un nouveau prestige. Il les traita de sots et de butors jusqu’à plus soif, leur dit qu’il était indispensable de me laisser causer avec le docteur, leur brandit la carte sous le nez, leur demanda s’ils allaient rompre le traité le jour même de partir à la chasse au trésor.
