From month to month the conviction grew upon the Protestants that their destruction was agreed upon. There was no doubt with regard to the desire of Philip the Second; for his course respecting his subjects in the Netherlands showed plainly enough that the extermination of heretics was the only policy of which his narrow mind could conceive as pleasing in the sight of heaven. The character of Catharine--stealthy, deceitful, regardless of principle--was equally well understood. Between such a queen and the trusted minister of such a prince, a secret conference like that of Bayonne could not be otherwise than highly suspicious. It is not strange that the Huguenots received it as an indubitable fact that the court from this time forward was only waiting for the best opportunity of effecting their ruin; for even intelligent Roman Catholics, who were not admitted into the confidence of the chief actors in that celebrated interview, came to the same conclusion. Those who knew what had actually been said and done might assure the world that the rumors were false; but the more they asseverated the less they were believed. For it is one of the penalties of insincere and lying diplomacy, that when once appreciated in its true character--as it generally is appreciated in a very brief space of time--it loses its persuasive power, and is treated without much investigation as uniform imposture.[418] With a suspicious vigilance, bred of the very treachery of which they had so often been the victims, the Huguenots saw signs of dangers that perhaps were not actually in preparation for them. And certainly there was enough to alarm. Not many months after the assembly of Moulins a cut-throat by the name of Du May was discovered and executed, who had been hired to murder Admiral Coligny, the most indispensable leader of the party, near his own castle of Chatillon-sur-Loing.[419] The last day of the year there was hung a lackey, who pretended that the Cardinal of Lorraine had tried to induce him to poison the Prince of Porcien; and, although he retracted his statements at the time of his "amende honorable,"[420] his first story was generally credited. The rumor was current that in December, 1566, Charles received special envoys from the emperor, the Pope, and the King of Spain, warning him that, unless he should revoke his edict of toleration, they would declare themselves his open enemies.[421] This was certainly sufficiently incredible, so far as the tolerant Maximilian was concerned; but stranger mutations of policy had often been noticed, and, as to Pius the Fifth and Philip, nothing seemed more probable.
