So Andronicus, another son of John Palæologus, entered into friendship with Saoudji, one of the sons of Amurath. Saoudji was jealous of the favour shown to Bajazet, his brother, and resented the latter’s popularity—well deserved too, for he was valiant and successful in the field, and through the rapidity and vigour of his charges acquired the epithet of Yilderim, or Lightning.

So while Amurath was away in Asia, Saoudji and Andronicus, with the assistance of a band of Greek nobles and retainers, organized a combined revolt against the Byzantine and Turkish Governments. Amurath got tidings of this, and forthwith recrossed the Hellespont.

Suspecting Palæologus of complicity, Amurath compelled him to join in his proceedings to quell the revolt. The rebel forces were encamped near the town of Apicidion, and Amurath marched against them.

Unattended and under cover of night he rode to the entrenchments of their camp and called aloud to the Turkish insurgents, commanding them to return to their allegiance, promising a general amnesty. All these on hearing the familiar voice deserted their new leader and their Byzantine allies, and rejoined the forces of Amurath. Saoudji and Andronicus with his Greek followers were speedily taken. Saoudji was brought before his father, who commanded first that his eyes should be put out as unworthy to look his last upon the day, and then that he should be slain. The Greek insurgents were tied together and flung two or three at a time into the Maritza, while Amurath sat by until the last was drowned. The fathers of some of the rebels were ordered to slay their children before him; those who refused were themselves destroyed. Amurath ended by sending Andronicus in fetters to his father, commanding him to deal with him even as he had dealt with his own.

And after all the suppliant Emperor’s journey to Rome failed to arouse the Western nations to undertake a new crusade. All that was achieved was a confederacy to resist the future progress of the Ottoman power, and if possible to dispossess it of its European territories. The Sclavonic nations, at the confines of whose territories the Turks had arrived, joined together at the instigation of Servia. Servians, then the best troops and the most formidable the Turks had met in Europe, Bosnians, Albanians and Bulgarians, and with them Magyars and men from Wallachia took the field. Though at times successful, the alliance failed eventually in its purpose, and not until most recent times have those nations emerged from Turkish suzerainty to national independence.

The Battle of Kossova broke the power of the Sclavonic race in the Balkans and led to their disappearance from the arena of the polity of nations for many centuries. A fierce fight it was that raged all day with varying fortunes and glorious display of chivalry and knightly daring, where Bajazet the Lightning struck swift and sure, though a Christian noble ended the conqueror’s career when the fortunes of the day had just turned in his favour.

It happened thus, one Milosh Kabilovitch galloped forth as if a deserter from the Servian ranks and sought the royal presence of Amurath. He alleged important intelligence concerning the plans of the allies. Kneeling before Amurath, he suddenly leapt up and by one stroke buried his dagger in the monarch’s heart. By a miraculous exercise of strength he beat off all the attendants who surrounded him again and again, but finally fell under the sabres of the Janissaries just as he had reached the spot where he had left his horse. Amurath survived but to the close of the battle. His last act was to order the death of the captured Lazarus, king of Servia, who had commanded the centre of the Christian force, and who, standing in chains, regaled the dying eyes of his conqueror.

News of this momentous happening reached Constantinople, and we can guess that the faces of those who frequented the Atrium grew gloomier. Was there no one who could help? The horns of the Crescent were closing in on the City of Constantine, the Empire was shorn of most of its former glory and its vast possessions. Little but the city and its immediate surroundings were left unsubdued, all escape from the conquering Turk seemed hopeless. And then what were their prospects? to be conquered, and by such ruthless hands! The death of Saoudji may have been reckoned an act of justice, but rumours came to them, and proved true, of other deeds more cruel, of how Bajazet ascended the throne, like Richmond on Bosworth field, of how his brother Yakoub, who had fought valiantly in the Battle of Kossova, and had contributed largely to its success, was summoned to the regal tent and there saw his father’s body, the first intimation of his death. How then and there in the presence of that body Bajazet had immediately ordered his sorrowing brother to be strangled. This act was done, says Seaddedin, the Turkish historian, in conformity with the precept of the Koran, “Disturbance is worse than murder.” Surely a gloomy outlook for the watchers on the wall.

But how awful would be the fate of their city which had so long resisted the sacred Scimitar of Ottoman! What mercy could they expect? Help there was none, and Bajazet was making preparations to submit Constantinople to yet another siege. But he was diverted by hostilities on his western frontier, and hope revived again in the hearts of those that looked over the city walls across the Sea of Marmora. For the Christian natives of the West had at last begun to realize the danger threatening them from the East. They were moved not by the recommendation of a heretic Greek emperor, but urged by the supplications of the King of Hungary, a spiritual vassal of the Roman See. Pope Boniface IX proclaimed a crusade against the Turks, and promised plenary indulgence to those who should engage in an expedition for the defence of Hungary, and the neighbouring Catholic States.

There were fewer sinners in need of indulgence in those days than there are now; but the population of Europe was proportionately smaller. Yet many rallied to the banners of Philip of Artois; Comte d’Eu, Constable of France; Vienne, Admiral; and Bourcicault, Marshal of France. The Count of Hohenzollern, Grand Prince of the Teutonic order, led a force of Germans; the Knights of St. John of Jerusalem, led by their Grand Master Naillac, joined the force of some 120,000 allies, all, as Froissart says, “of tried courage and enterprise.” Their aim was to break the power of Bajazet in Hungary, and when this was done to advance on Constantinople, cross the Hellespont, enter Syria, gain the Holy Land, and deliver Jerusalem with its Holy Sepulchre from the hands of infidels.
