The eighth war, the “War of the Three Henries,” that is, of Henri III. and Henri de Guise against Henri of Navarre, now broke out. The Pope made his voice heard; Sixtus excommunicated the Bourbons, Henri and Conde, and blessed the Leaguers.
For the first time there was some real life in one of these civil ware, for Henri of Navarre rose nobly to the level of his troubles. At first the balance of successes was somewhat in favour of the Leaguers; the political atmosphere grew even more threatening, and terrible things, like lightning flashes, gleamed out now and again. Such, for example, was the execution of Mary Stuart, Queen of Scots, in 1586. It was known that Philip II. was preparing to crush England. Elizabeth did what she could to support Henri of Navarre; he had the good fortune to win the battle of Contras, in which the Duc de Joyeuse, one of the favourites of Henri III., was defeated and killed. The Duc de Guise, on the other hand, was too strong for the Germans, who had marched into France to join the Huguenots, and defeated them at Vimroy and Auneau, after which he marched in triumph to Paris, in spite of the orders and opposition of. the King, who, finding himself powerless, withdrew to Chartres. Once more Henri III. was obliged to accept such terms as the Leaguers chose to impose; and with rage in his heart he signed the “Edict of Union” (1588), in which he named the Duc de Guise lieutenant-general of the kingdom, and declared that no heretic could succeed to the throne.
