When he was fifteen, the third religious war broke out. Both his father and grandfather were dead. His mother, who had openly professed the reformed faith, since the death of her husband, who hated it, brought her boy to the camp at Rochelle, where he was received as the chief of the Huguenots. His culture was not extensive. He had learned to speak the truth, to ride, to shoot, to do with little sleep and less food. He could also construe a little Latin, and had read a few military treatises; but the mighty hours of an eventful life were now to take him by the hand, and to teach him much good and much evil, as they bore him onward. He now saw military treatises expounded practically by professors, like his uncle Condo, and Admiral Coligny, and Lewis Nassau, in such lecture-rooms as Laudun, and Jarnac, and Montcontour, and never was apter scholar. The peace of Arnay-le-Duc succeeded, and then the fatal Bartholomew marriage with the Messalina of Valois. The faith taught in the mountains of Bearn was no buckler against the demand of "the mass or death," thundered at his breast by the lunatic Charles, as he pointed to thousands of massacred Huguenots. Henry yielded to such conclusive arguments, and became a Catholic. Four years of court imprisonment succeeded, and the young King of Navarre, though proof to the artifices of his gossip Guise, was not adamant to the temptations spread for him by Catherine de' Medici. In the harem entertained for him in the Louvre many pitfalls entrapped him; and he became a stock-performer in the state comedies and tragedies of that plotting age. A silken web of palace-politics, palace-diplomacy, palace revolutions, enveloped him. Schemes and counter-schemes, stratagems and conspiracies, assassinations and poisonings; all the state-machinery which worked so exquisitely in fair ladies' chambers, to spread havoc and desolation over a kingdom, were displayed before his eyes. Now campaigning with one royal brother against Huguenots, now fighting with another on their side, now solicited by the Queen-Mother to attempt the life of her son, now implored by Henry III. to assassinate his brother, the Bearnese, as fresh antagonisms, affinities; combinations, were developed, detected, neutralized almost daily, became rapidly an adept in Medicean state- chemistry. Charles IX. in his grave, Henry III. on the throne, Alencon in the Huguenot camp--Henry at last made his escape. The brief war and peace of Monsieur succeeded, and the King of Navarre formally abjured the Catholic creed. The parties were now sharply defined. Guise mounted upon the League, Henry astride upon the Reformation, were prepared to do battle to the death. The temporary "war of the amorous" was followed by the peace of Fleix.
