Heart of Europe by Ralph Adams Cram

When Philip II came to the throne there was a new king in France, Henry II, who forthwith broke the peace Charles V had engineered, and proceeded to invade both Italy and Flanders. He was promptly beaten, in the north by Egmont at St. Quentin, and after so disastrous a fashion that hardly any one but Nevers and Condé escaped. It was in gratitude for the brilliant victory of his Belgian troops that Philip built the palace of the Escorial. Trying again the next year, Henry did indeed, through the Duke de Guise (whose luck was better than that which followed him when he met Alva the year before in Italy), regain Calais, during the absence of the English garrison, who were home on a holiday; but again Egmont came into the breech, crushed the French at Gravelines, and so forced the treaty of Câteau-Cambrésis, which obliged France, amongst other penalties, to give up to Philip more than two hundred walled towns, though she was allowed to retain Calais, Mary of England now being dead.

Flemish soldiers, now forming the best trained and most effective army in Europe, had won the war for Philip, but out of the victory came in the end the ruin of their country, for before leaving for Spain, which he loved, he demanded of the Netherlands, which he disliked, three million florins toward the expense of the war. This was granted, but coupled with a request that the Spanish garrison be withdrawn. It happened that this demand was made at the instigation of William, Prince of Orange, who now appears on the scene, for he had discovered that Henry and Philip had secretly agreed to stamp out Protestantism in the Low Countries by introducing the Spanish Inquisition, and that the alien garrison was to be the means of putting this plan into effect. William of Orange was not a Fleming but a German; he had expected to be made regent when the King went back to Spain, and had been disappointed. He was neither a Catholic nor a Protestant, but a cold, silent, far-seeing politician of extremely rationalistic views. He knew that the spirit of independence in the Netherlands was so dominating that Catholics and Protestants alike could be allied against both the Inquisition and a foreign garrison. He cleverly united them on this basis, alienated the last flicker of friendly feeling on the part of Philip, and so precipitated the conflict that raged for almost a century to the ruin and misery of all the seventeen provinces. Philip appeared to yield, went back to Spain, and at once began his scheming for the destruction of the Protestant heresy in his too-independent territories.
