But these two passed masters in duplicity could not, even in misfortune, trust one another, and Alexius III, the craftier if not the stronger of the two vagabond usurpers, seized his ally, put out his eyes, and handed him over to the Latins. They went through the formality of a trial, and found him guilty of the murder of Alexius IV. He was sentenced to death, and after a good deal of discussion it was decided that the manner of his death should be by being hurled from the top of a lofty column, and this was accordingly done.

As for Alexius III, after a great variety of adventures he finally fell into the hands of his son-in-law, Theodore Lascaris, who shut him up in a monastery, where his troubled life came to an end.

Baldwin began his reign by sending a conciliatory letter to the Pope.[51] He had not, it is true, attempted to carry out the vows which he and his brother-crusaders had taken upon themselves. Palestine still groaned under the yoke of the infidel. At the same time the Pope could not but feel gratified at the extinction of the Greek schism and the restoration of the unity of Christendom, That event was undoubtedly due to him, and the Pope acknowledged it in a careful letter, which left him free at any time to express his disapprobation of the course pursued by the crusaders. To the King of France Baldwin wrote, inviting the French knights to find their way to this new scene of conquest and glory. To Palestine he sent promises of assistance, with, as tokens of his power, the gates of Constantinople and the chain which barred the port.

And then, the empire being fairly parcelled out, the Marquis of Montferrat took his knights and men-at-arms to establish his own kingdom of Thessalonica. Other chiefs, who had obtained each his own part of the Byzantine territories, went off to conquer them for themselves; and the Greeks began to perceive that they were ruled by a mere handful of Latin adventurers, only to be dreaded when they were together, and now scattered in small garrisons and feeble bands all about the country. When this knowledge was thoroughly acquired, troubles began to befall the new empire.

These troubles were originated, however, not by the Greeks, but by the Bulgarians, and were due to the arrogance and pride of Baldwin. John, King of this savage people, was of the Latin Church. Being as orthodox as he was barbarous, he rejoiced mightily at the fall of the Greeks, and sent an embassy of congratulation to the new Latin Emperor. Weak as he was upon his unstable throne, Baldwin actually had the folly and impudence to assault these ambassadors, to treat them as rebels, and to send a message to their master that, before his servants could be received at the Byzantine court, he must first deserve pardon by touching with his forehead the footstool of the imperial throne. It was not likely that a high-spirited and independent sovereign would brook such a message.

He instantly threw the whole weight of his influence and strength into the cause of the Greeks, and with their leaders concerted a scheme of general and simultaneous massacre worthy of his barbarism and their treachery. The secret was well kept; the conspirators were in no hurry to strike the blow. They waited patiently till a time when it seemed as if the force of the Latins was at the lowest; that is, when Prince Henry, brother of the Emperor, had crossed the Hellespont with the flower of the troops. The empire in Europe was covered with thin and sparse garrisons; there were no forces in Constantinople to come to their succor should they try to hold out; they might be taken in detail and at once. And then those Byzantine Vespers began. It was a revolt of thousands against tens; there was a great slaughter, a rush of the little bands who escaped upon Adrianople, where there was a fresh slaughter; and while the Greeks were up in successful revolt, the Bulgarians, accompanied by a savage band of fourteen thousand Comans, invaded the country, mad for pillage and revenge.

The position was one of extreme peril. Baldwin sent messengers to his brother, ordering him to return in all haste, and then made such hasty preparations as were possible, and sallied forth to the siege of Adrianople. Had he waited for Henry's return, all might have gone well with him, but he would not wait. It was the rule of the crusaders never to refuse battle, whatever the odds, a rule to which their greatest victories as well as their greatest disasters were chiefly due. What Godfrey did before Ascalon, Baldwin was ready to do before Adrianople. He had with him no more than a hundred and forty knights, with three trains of archers and men-at-arms—say two thousand men in all. The gallant Villehardouin, Marshal of Romania, who was destined to survive this day and write its story, led the vanguard.

The main body, with whom was Baldwin, was commanded by the Count of Blois; the rear was brought up by old Dandolo. The slender ranks of the little army were continually being recruited by the accession of the fugitive remains of the garrisons. On the way to Adrianople they met the light cavalry of the Comans. Orders were given not to pursue these light horsemen, who fought after the manner of the Parthians. In a solid phalanx the western knights were able to face any odds, but scattered and dispersed they would fall beneath the weight of numbers.

The order insisted on by Dandolo, who knew this kind of enemy, was broken by no others than the Emperor himself and the Count of Blois. The Comans, as usual, fled at the first charge of the heavily armed knights, who spurred after them, regardless of the order, and led by the Emperor. When they had ridden a mile or so, when their horses were breathed, then the Comans closed in upon the little band of knights, and the unequal contest began of a hundred and forty against fourteen thousand. Some few struggled out of the mêlée and found their way back to the rest of the army. Most fell upon the field. Among these was the Count of Blois. A few were taken prisoners, among whom was the Emperor. No one ever knew his fate. The wildest stories were told of this unfortunate Prince. His hands and feet, it was said, were cut off, and he was exposed, mutilated, to the wild animals; he was beheaded; he enacted the part of Joseph—Potiphar's wife being King John's queen. Nothing was too wild to be believed about him. Twenty years later a hermit of the Netherlands thought it would be possible to pass himself off as the real Baldwin, who had escaped from captivity and was thus expiating his early sins.

He obtained the fate from justice and the sympathy from the vulgar which have commonly been the lot of pretenders. Whatever the real end of this Emperor, King John wrote a year later to the Pope, calmly informing him that his intercession for Baldwin was no longer of any use, because he was no longer living. Then it was, and not till then, that his brother, Henry of Flanders, consented to assume the title of Emperor. Already the leaders of the crusade, who only three years before had set sail so proudly from Venice, were dead or on the point of death: Baldwin murdered in captivity; the Count of Blois killed on the field of battle; Dandolo dead, at the age, say some writers, of a hundred, in the year 1205; the Marquis of Montferrat about to be slain in an obscure skirmish with the barbarous Bulgarians.
