The swift ebb-tide swept the hats of the perishing wretches in such numbers down the stream, that the people at Embden knew the result of the battle in an incredibly short period of time. The skirmishing had lasted from ten o'clock till one, but the butchery continued much longer. It took time to slaughter even unresisting victims. Large numbers obtained refuge for the night upon an island in the river. At low water next day the Spaniards waded to them, and slew every man. Many found concealment in hovels, swamps, and thickets, so that the whole of the following day was occupied in ferreting out and despatching them. There was so much to be done, that there was work enough for all. "Not a soldier," says, with great simplicity, a Spanish historian who fought in the battle, "not a soldier, nor even a lad, who wished to share in the victory, but could find somebody to wound, to kill, to burn, or to drown." The wounding, killing, burning, drowning lasted two days, and very few escaped. The landward pursuit extended for three or four leagues around, so that the roads and pastures were covered with bodies, with corslets, and other weapons. Count Louis himself stripped off his clothes, and made his escape, when all was over, by swimming across the Ems. With the paltry remnant of his troops he again took refuge in Germany.

The Spanish army, two days afterwards, marched back to Groningen. The page which records their victorious campaign is foul with outrage and red with blood. None of the horrors which accompany the passage of hostile troops through a defenceless country were omitted. Maids and matrons were ravished in multitudes; old men butchered in cold blood. As Alva returned, with the rear-guard of his army, the whole sky was red with a constant conflagration; the very earth seemed changed to ashes. Every peasant's hovel, every farm-house, every village upon the road had been burned to the ground. So gross and so extensive had been the outrage, that the commander-in-chief felt it due to his dignity to hang some of his own soldiers who had most distinguished themselves in this work. Thus ended the campaign of Count Louis in Friesland. Thus signally and terribly had the Duke of Alva vindicated the supremacy of Spanish discipline and of his own military skill.

On his return to Groningen, the estates were summoned, and received a severe lecture for their suspicious demeanour in regard to the rebellion. In order more effectually to control both province and city, the Governor-general ordered the construction of a strong fortress, which was soon begun but never completed. Having thus furnished himself with a key to this important and doubtful region, he returned by way of Amsterdam to Utrecht. There he was met by his son Frederic with strong reinforcements. The Duke reviewed his whole army, and found himself at the head of 30,000 infantry and 7,000 cavalry. Having fully subdued the province, he had no occupation for such a force, but he improved the opportunity by cutting off the head of an old woman in Utrecht. The Vrow van Diemen, eighteen months previously, had given the preacher Arendsoon a night's lodging in her house. The crime had, in fact, been committed by her son-in-law, who dwelt under her roof, and who had himself, without her participation, extended this dangerous hospitality to a heretic; but the old lady, although a devout Catholic, was rich. Her execution would strike a wholesome terror into the hearts of her neighbours. The confiscation of her estates would bring a handsome sum into the government coffers. It would be made manifest that the same hand which could destroy an army of twelve thousand rebels at a blow could inflict as signal punishment on the small delinquencies of obscure individuals. The old lady, who was past eighty-four years of age, was placed in a chair upon the scaffold. She met her death with heroism, and treated her murderers with contempt. "I understand very well," she observed, "why my death is considered necessary. The calf is fat and must be killed." To the executioner she expressed a hope that his sword was sufficiently sharp, "as he was likely to find her old neck very tough." With this grisly parody upon the pathetic dying words of Anne Boleyn, the courageous old gentlewoman submitted to her fate.

The tragedy of Don Carlos does not strictly belong to our subject, which is the rise of the Netherland commonwealth—not the decline of the Spanish monarchy, nor the life of Philip the Second. The thread is but slender which connects the unhappy young prince with the fortunes of the northern republic. He was said, no doubt with truth, to desire the government of Flanders. He was also supposed to be in secret correspondence with the leaders of the revolt in the provinces. He appeared, however, to possess very little of their confidence. His name is only once mentioned by William of Orange, who said in a letter that "the Prince of Spain had lately eaten sixteen pounds of fruit, including four pounds of grapes at a single sitting, and had become ill in consequence." The result was sufficiently natural, but it nowhere appears that the royal youth, born to consume the fruits of the earth so largely, had ever given the Netherlanders any other proof of his capacity to govern them. There is no doubt that he was a most uncomfortable personage at home, both to himself and to others, and that he hated his father' very cordially. He was extremely incensed at the nomination of Alva to the Netherlands, because he had hoped that either the King would go thither or entrust the mission to him, in either of which events he should be rid for a time of the paternal authority, or at least of the paternal presence. It seems to be well ascertained that Carlos nourished towards his father a hatred which might lead to criminal attempts, but there is no proof that such attempts were ever made. As to the fabulous amours of the Prince and the Queen, they had never any existence save in the imagination of poets, who have chosen to find a source of sentimental sorrow for the Infante in the arbitrary substitution of his father for himself in the marriage contract with the daughter of Henry the Second. As Carlos was but twelve or thirteen years of age when thus deprived of a bride whom he had never seen, the foundation for a passionate regret was but slight. It would hardly be a more absurd fantasy, had the poets chosen to represent Philip's father, the Emperor Charles, repining in his dotage for the loss of "bloody Mary," whom he had so handsomely ceded to his son. Philip took a bad old woman to relieve his father; he took a fair young princess at his son's expense; but similar changes in state marriages were such matters of course, that no emotions were likely to be created in consequence. There is no proof whatever, nor any reason to surmise; that any love passages ever existed between Don Carlos and his step-mother.

As to the process and the death of the Prince, the mystery has not yet been removed, and the field is still open to conjecture. It seems a thankless task to grope in the dark after the truth at a variety of sources; when the truth really exists in tangible shape if profane hands could be laid upon it. The secret is buried in the bosom of the Vatican. Philip wrote two letters on the subject to Pius V. The contents of the first (21st January, 1568) are known. He informed the pontiff that he had been obliged to imprison his son, and promised that he would, in the conduct of the affair, omit nothing which could be expected of a father and of a just and prudent king. The second letter, in which he narrated, or is supposed to have narrated, the whole course of the tragic proceedings, down to the death and burial of the Prince, has never yet been made public. There are hopes that this secret missive, after three centuries of darkness, may soon see the light.—[I am assured by Mr. Gachard that a copy of this important letter is confidently expected by the Commission Royale d'Histoire.]

As Philip generally told the truth to the Pope, it is probable that the secret, when once revealed, will contain the veritable solution of the mystery. Till that moment arrives, it seems idle to attempt fathoming the matter. Nevertheless, it may be well briefly to state the case as it stands. As against the King, it rests upon no impregnable, but certainly upon respectable authority. The Prince of Orange, in his famous Apology, calls Philip the murderer of his wife and of his son, and says that there was proof of the facts in France. He alludes to the violent death of Carlos almost as if it were an indisputable truth. "As for Don Charles," he says, "was he not our future sovereign? And if the father could allege against his son fit cause for death, was it not rather for us to judge him than for three or four monks or inquisitors of Spain?"

The historian, P. Matthieu, relates that Philip assembled his council of conscience; that they recommended mercy; that hereupon Philip gave the matter to the inquisition, by which tribunal Carlos was declared a heretic on account of his connexion with Protestants, and for his attempt against his father's life was condemned to death, and that the sentence was executed by four slaves, two holding the arms, one the feet, while the fourth strangled him.

De Thou gives the following account of the transaction, having derived many of his details from the oral communications of Louis de Foix:

Philip imagined that his son was about to escape from Spain, and to make his way to the Netherlands. The King also believed himself in danger of assassination from Carlos, his chief evidence being that the Prince always carried pistols in the pockets of his loose breeches. As Carlos wished always to be alone at night without any domestic in his chamber, de Foix had arranged for him a set of pulleys, by means of which he could open or shut his door without rising from his bed. He always slept with two pistols and two drawn swords under his pillow, and had two loaded arquebusses in a wardrobe close at hand. These remarkable precautions would seem rather to indicate a profound fear of being himself assassinated; but they were nevertheless supposed to justify Philip's suspicions, that the Infante was meditating parricide. On Christmas eve, however (1567), Don Carlos told his confessor that he had determined to kill a man. The priest, in consequence, refused to admit him to the communion. The Prince demanded, at least, a wafer which was not consecrated, in order that he might seem to the people to be participating in the sacrament. The confessor declined the proposal, and immediately repairing to the King, narrated the whole story. Philip exclaimed that he was himself the man whom the Prince intended to kill, but that measures should be forthwith taken to prevent such a design. The monarch then consulted the Holy Office of the inquisition, and the resolution was taken to arrest his son. De Foix was compelled to alter the pulleys of the door to the Prince's chamber in such a manner that it could be opened without the usual noise, which was almost sure to awaken him. At midnight, accordingly, Count Lerma entered the room so stealthily that the arms were all, removed from the Prince's pillow and the wardrobe, without awakening the sleeper. Philip, Ruy Gomez, the Duke de Feria, and two other nobles, then noiselessly, crept into the apartment. Carlos still slept so profoundly that it was necessary for Derma to shake him violently by the arm before he could be aroused. Starting from his sleep in the dead of night, and seeing his father thus accompanied, before his bed, the Prince cried out that he was a dead man, and earnestly besought the bystanders to make an end of him at once. Philip assured him, however, that he was not come to kill him, but to chastise him paternally, and to recall him to his duty. He then read him a serious lecture, caused him to rise from his bed, took away his servants, and placed him under guard. He was made to array himself in mourning habiliments, and to sleep on a truckle bed. The Prince was in despair. He soon made various attempts upon his own life. He threw himself into the fire, but was rescued by his guards, with his clothes all in flames. He passed several days without taking any food, and then ate so many patties of minced meat that he nearly died of indigestion. He was also said to have attempted to choke himself with a diamond, and to have been prevented by his guard; to have filled his bed with ice; to have sat in cold draughts; to have gone eleven days without food, the last method being, as one would think, sufficiently thorough. Philip, therefore, seeing his son thus desperate, consulted once more with the Holy Office, and came to the decision that it was better to condemn him legitimately to death than to permit him to die by his own hand. In order, however, to save appearances, the order was secretly carried into execution. Don Carlos was made to swallow poison in a bowl of broth, of which he died in a few hours. This was at the commencement of his twenty-third year. The death was concealed for several months, and was not made public till after Alva's victory at Jemmingen.

Such was the account drawn up by de Thou from the oral communications of de Foix, and from other sources not indicated. Certainly, such a narrative is far from being entitled to implicit credence. The historian was a contemporary, but he was not in Spain, and the engineer's testimony is, of course, not entitled to much consideration on the subject of the process and the execution (if there were an execution); although conclusive as to matters which had been within his personal knowledge. For the rest, all that it can be said to establish is the existence of the general rumor, that Carlos came to his death by foul means and in consequence of advice given by the inquisition.
