Within two years there had been five distinct attempts to assassinate the Prince, all of them with the privity of the Spanish government. A sixth was soon to follow. In the summer of 1584 William of Orange was residing at Delft, where his wife, Louisa de Coligny, had given birth, in the preceding winter, to a son, afterward the celebrated stadtholder Frederick Henry. The child had received these names from his two godfathers, the kings of Denmark and of Navarre, and his baptism had been celebrated with much rejoicing on June 12th, in the place of his birth.

It was a quiet, cheerful, yet somewhat drowsy little city, that ancient burgh of Delft. The placid canals by which it was intersected in every direction were all planted with whispering, umbrageous rows of limes and poplars, and along these watery highways the traffic of the place glided so noiselessly that the town seemed the abode of silence and tranquillity. The streets were clean and airy, the houses well built, the whole aspect of the place thriving.

One of the principal thoroughfares was called the Old Delft Street. It was shaded on both sides by lime-trees, which in that midsummer season covered the surface of the canal which flowed between them with their light and fragrant blossoms. On one side of this street was the "Old Kirk," a plain, antique structure of brick, with lancet windows, and with a tall, slender tower, which inclined, at a very considerable angle, toward a house upon the other side of the canal. That house was the mansion of William the Silent. It stood directly opposite the church, being separated by a spacious court-yard from the street, while the stables and other offices in the rear extended to the city wall. A narrow lane, opening out of Delft Street, ran along the side of the house and court in the direction of the ramparts. The house was a plain, two-storied edifice of brick, with red-tiled roof, and had formerly been a cloister dedicated to St. Agatha, the last prior of which had been hanged by the furious Lumey de la Marck.[1] ]

The news of Anjou's death had been brought to Delft by a special messenger from the French court. On Sunday morning, July 8, 1584, the Prince of Orange, having read the despatches before leaving his bed, caused the man who had brought them to be summoned, that he might give some particular details by word of mouth concerning the last illness of the Duke. The courier was accordingly admitted to the Prince's bedchamber, and proved to be one Francis Guion, as he called himself. This man had, early in the spring, claimed and received the protection of Orange, on the ground of being the son of a Protestant at Besançon who had suffered death for his religion and of his own ardent attachment to the reformed faith. A pious, psalm-singing, thoroughly Calvinistic youth he seemed to be, having a Bible or a hymn-book under his arm whenever he walked the street, and most exemplary in his attendance at sermon and lecture. For the rest, a singularly unobtrusive personage, twenty-seven years of age, low of stature, meagre, mean-visaged, muddy-complexioned, and altogether a man of no account—quite insignificant in the eyes of all who looked upon him. If there were one opinion, in which the few who had taken the trouble to think of the puny, somewhat shambling stranger from Burgundy at all, coincided, it was that he was inoffensive, but quite incapable of any important business. He seemed well educated, claimed to be of respectable parentage, and had considerable facility of speech when any person could be found who thought it worth while to listen to him; but on the whole he attracted little attention.

Nevertheless this insignificant frame locked up a desperate and daring character; this mild and inoffensive nature had gone pregnant seven years with a terrible crime, whose birth could not much longer be retarded. Francis Guion, the Calvinist, son of a martyred Calvinist, was in reality Balthazar Gérard, a fanatical Catholic, whose father and mother were still living at Villefans in Burgundy. Before reaching man's estate he had formed the design of murdering the Prince of Orange, "who, so long as he lived, seemed like to remain a rebel against the Catholic King, and to make every effort to disturb the repose of the Roman Catholic apostolic religion."

When but twenty years of age he had struck his dagger with all his might into a door, exclaiming as he did so, "Would that the blow had been in the heart of Orange!" For this he was rebuked by a bystander, who told him it was not for him to kill princes, and that it was not desirable to destroy so good a captain as the Prince, who, after all, might one day reconcile himself with the King.

The "inveterate deliberation," thus thoroughly matured, Gérard now proceeded to carry into effect. He came to Delft, obtained a hearing of Villers, the clergyman and intimate friend of Orange, and was somewhat against his will sent to France, to Maréchal Biron, who, it was thought, was soon to be appointed governor of Cambray. Through Orange's recommendation the Burgundian was received into the suite of Noel de Caron, Seigneur de Schoneval, then setting forth on a special mission to the Duke of Anjou. While in France Gérard could rest neither by day nor night, so tormented was he by the desire of accomplishing his project, and at length he obtained permission, upon the death of the Duke, to carry this important intelligence to the Prince of Orange. The despatches having been intrusted to him, he travelled post-haste to Delft, and, to his astonishment, the letters had hardly been delivered before he was summoned in person to the chamber of the Prince. Here was an opportunity such as he had never dared to hope for. The arch-enemy to the Church and to the human race, whose death would confer upon his destroyer wealth and nobility in this world, besides a crown of glory in the next, lay unarmed, alone, in bed, before the man who had thirsted seven long years for his blood.

Balthazar could scarcely control his emotions sufficiently to answer the questions which the Prince addressed to him concerning the death of Anjou, but Orange, deeply engaged with the despatches, and with the reflections which their deeply important contents suggested, did not observe the countenance of the humble Calvinist exile, who had been recently recommended to his patronage by Villers. Gérard had, moreover, made no preparation for an interview so entirely unexpected, had come unarmed, and had formed no plan for escape. He was obliged to forego his prey when most within his reach, and, after communicating all the information which the Prince required, he was dismissed from the chamber.

It was Sunday morning, and the bells were tolling for church. Upon leaving the house he loitered about the court-yard, furtively examining the premises, so that a sergeant of halberdiers asked him why he was waiting there. Balthazar meekly replied that he was desirous of attending divine worship in the church opposite, but added, pointing to his shabby and travel-stained attire, that, without at least a new pair of shoes and stockings, he was unfit to join the congregation. Insignificant as ever, the small, pious, dusty stranger excited no suspicion in the mind of the good-natured sergeant. He forthwith spoke of the wants of Gérard to an officer, by whom they were communicated to Orange himself, and the Prince instantly ordered a sum of money to be given him. Thus Balthazar obtained from William's charity what Parma's thrift had denied—a fund for carrying out his purpose.

Next morning, with the money thus procured, he purchased a pair of pistols, or small carabines, from a soldier, chaffering long about the price because the vender could not supply a particular kind of chopped bullets or slugs which he desired. Before the sunset of the following day, that soldier had stabbed himself to the heart, and died despairing, on hearing for what purpose the pistols had been bought.
