The council of Isaac and Alexius breathed nothing but vengeance; and, on the return of the deputies, war was decided on in the council of the barons. The Latins determined to attack Constantinople; nothing could equal the hatred and fury of the Greeks; but fury and hatred cannot supply the place of courage: not daring to meet their enemy in the open field, they resolved to burn the fleet of the Venetians. The Greeks, on this occasion, had again recourse to that Greek fire, which had, more than once, served them instead of courage, and saved their capital. This terrible fire, skilfully hurled or directed, devoured vessels, soldiers, and their arms; like the bolt of Heaven, nothing could prevent its explosion, or arrest its ravages; the waves of the sea, so far from extinguishing it, redoubled its activity. Seventeen ships, charged with the Greek fire and combustible matter, were carried by a favourable wind towards the port in which the Venetian vessels lay at anchor. To assure the success of this attempt, the Greeks took advantage of the darkness of night; and the port, the gulf, and the faubourg of Galata were, all at once, illumined by a threatening and sinister light. At the aspect of the danger, the trumpets sounded the alarm in the camp of the Latins; the French flew to arms and prepared for the fight, whilst the Venetians cast themselves into their barks, and went out to meet vessels bearing within their sides destruction and fire.
The crowd of Greeks assembled on the shore, applauded the spectacle, and enjoyed the terror of the Crusaders. Many of them embarked in small boats, and rowed out upon the sea, darting arrows and endeavouring to carry disorder among the Venetians. The Crusaders encouraged each other; they rushed in crowds to encounter the danger, some raising plaintive and piercing cries towards Heaven, and others uttering horrible imprecations against the Greeks: on the walls of Constantinople, clapping of hands and cries of joy resounded, and were redoubled as the vessels covered with flames drew nearer. Villehardouin, an ocular witness, says that amidst this frightful tumult, nature appeared to be in confusion, and the sea about to swallow up the earth. Nevertheless, the Venetians, by the means of strong arms and numberless oars, succeeded in turning the course of the fire-ships wide of the port, and they were carried by the current beyond the canal. The Crusaders, in battle array, standing on their vessels or dispersed among the barks, rendered thanks to God for having preserved them from so great a disaster; whilst the Greeks beheld with terror their fire-ships consuming away upon the waters of the Propontis, without having effected the least injury.
The irritated Latins could not pardon the perfidy and ingratitude of the emperor Alexius: “It was not enough for him to have failed in his engagements and broken his oaths, he endeavoured to burn the fleet that had borne him triumphantly to the heart of his empire: the time was now come to repress the enterprises of traitors by the sword, and to punish base enemies, who were acquainted with no other arms but treachery and deceit; and, like the vilest brigands, only ventured to deal their blows in the darkness and silence of night.” Alexius, terrified at these threats, could think of no other resource than that of imploring the clemency of the Crusaders. He offered them fresh oaths and fresh promises, and threw the blame of the hostilities upon the fury of the people, which he had not the power to restrain. He conjured his friends, his allies, his liberators, to come and defend a throne ready to fall to pieces beneath him, and proposed to give up his own palace to them.
Mourzoufle was directed to convey to the Latins the supplications and offers of the emperor, and, seizing the opportunity to augment the alarms and discontent of the multitude, he caused the report to be spread that he was going to deliver Constantinople up to the barbarians of the West. On learning this, the people assembled tumultuously in the streets and public places; the report became general that the enemies were already in the city, and all joined in the cry that to prevent the greatest calamities, not a moment was to be lost; the empire required a master who was able to defend and protect it.
Whilst the young prince, seized with terror, shut himself up in his palace, the crowd of insurgents flocked to the church of St. Sophia to choose a new emperor.
Since the imperial dynasties had become the playthings of the caprice of the multitude, and of the ambition of conspirators, the Greeks made the changing of their sovereigns quite a sport, without reflecting that one revolution produces other revolutions; and, to avoid present calamities, rushed headlong into new ones. The most prudent of the clergy and the patricians presented themselves at the church of St. Sophia, and earnestly endeavoured to prevent the evils with which the country was threatened. But it was in vain they explained to their excited auditory that by changing their master they were sure to overthrow both the throne and the empire. “When they asked my opinion,” says the historian Nicetas, “I was careful not to consent to the deposition of Isaac and Alexius, because I felt assured that the man they would elect in their place would not be the most able. But the people,” adds the same historian, “whose only motive of action is passion,—the people, who twenty years before had killed Andronicus and crowned Isaac, could not endure their own work and live under princes whom they themselves had chosen.” The multitude reproached their sovereign with their misery, which was the bitter fruit of the war; and with the weakness of their government, which was but the result of general corruption. The victories of the Latins, the inefficiency of the laws, the caprices of fortune, the very will of Heaven, all were gathered into one great accusation to be brought against those who governed the empire. The distracted crowd looked to a revolution for everything; a change of emperors appeared to them the only remedy for the ills under which they groaned. They pressed, they solicited the patricians and senators,—they scarcely knew the names of the men they wished to choose as masters; but any other than Isaac, any other than Alexius, must merit the esteem and love of the Greeks. To be the wearer of a purple robe, was quite enough to entitle a man to ascend the throne of Constantine. Some excused themselves on account of age, others from alleged incapacity. The people, sword in hand, required them to accept the sovereign authority. At length, after three days of stormy debate, an imprudent young man, named Canabus, allowed himself to be prevailed upon by the prayers and threats of the people. A phantom of an emperor was crowned in the church of St. Sophia, and proclaimed in Constantinople. Mourzoufle was no stranger to this popular revolution. Several historians have thought that he promoted the election of an obscure man, to test the peril in some sort, and to become acquainted with the power and will of the people, in order, one day, to profit by it himself.
Alexius, made aware of this revolution, trembled in the recesses of his deserted palace; he had no hope but in the Latins; he solicited, by messages, the support of the barons; he implored the pity of the marquis of Montferrat; who, touched by his prayers, entered Constantinople by night, and came, at the head of a chosen troop, to defend the throne and the lives of the emperors. Mourzoufle, who dreaded the presence of the Latins, flew to Alexius, to convince him that they were the most dangerous enemies he had, and told him that all would inevitably be lost if the Franks once appeared in arms in the palace.
When Boniface presented himself before the palace of Blachernæ, he found all the doors closed; Alexius caused him to be informed that he was no longer at liberty to receive him, and conjured him to leave Constantinople with his soldiers. The sight of the warriors of the West had spread terror throughout the city; their retreat revived both the courage and fury of the people. A thousand different rumours prevailed at once; the public places resounded with complaints and imprecations; from moment to moment the crowd became more numerous and the tumult increased. Amidst all this confusion and disorder, Mourzoufle never lost sight of the prosecution of his designs; by promises and caresses he won over the imperial guard, whilst his friends pervaded the capital, exciting the fury and rage of the multitude by their speeches and insinuations. An immense crowd soon assembled before the palace of Blachernæ, uttering seditious cries. Mourzoufle then presented himself before Alexius: he employed every means to aggravate the alarm of the young prince, and, under the pretext of providing for his safety, drew him into a secluded apartment, where his creatures, under his direction, loaded him with irons and cast him into a dungeon. Coming forth, he boldly informed the people what he had done for the salvation of the empire; and the throne, from which he had dragged his master, benefactor, and friend, appeared but a just recompense for the devotedness of his services: he was carried in triumph to the church of St. Sophia, and crowned emperor amidst the acclamations of the people. Scarcely was Mourzoufle clothed with the imperial purple, than he resolved to possess the fruit of his crime in security; dreading the caprice of both fortune and the people, he repaired to the prison of Alexius, forced him to swallow an empoisoned draught, and because death did not keep pace with his impatience, strangled him with his own hands.
Thus perished, after a reign of six months and a few days, the emperor Alexius, whom one revolution had placed upon a throne, and who disappeared amidst the storms of another, without having tasted any of the sweets of supreme rank, and without an opportunity of proving whether he was worthy of it. This young prince, placed in a most difficult situation, had not the power, and perhaps not the will, to rouse the Greeks to oppose the Crusaders. On the other side, he had not the tact to employ the support of the Latins so as to keep the Greeks within the bounds of obedience; directed by perfidious counsels, ever vacillating between patriotism and gratitude, fearing by turns to alienate his unhappy subjects, or to irritate his formidable allies, he perished, the victim of his own weakness and irresolution. Isaac Angelus, on learning the tragical end of his son, died of terror and despair; thus sparing Mourzoufle another parricide, of which he was not the less suspected to be guilty. History makes no more mention of Canabus; the confusion was so great that the Greeks were ignorant of the fate of a man whom but a few days before they had elevated to the rank of their sovereign; four emperors had been dragged violently from the throne since the arrival of the Latins, and fortune reserved the same fate for Mourzoufle.
