Bajazed, as soon as he had learned the presence of the combined Christian armies, marched through Philippopolis, crossed the Balkans, made for the Danube, and then waited for attack. In the battle which ensued (1396), Europe received its first lesson on the prowess of the Turks, and especially of the Janissaries. The Christian army, with rash daring, broke through the line of its enemies, cut down all who resisted them, and rushed on irresistible to the very rearguard of the Turks, many of whom either retreated or sought refuge in flight. When the French knights saw that the Turks ran, they followed, and filled the battlefield with dead and dying. But they made the old military blunder, and it led to the same old result. The archers, who always constituted the most effective Turkish arm, employed the stratagem of running away in order to throw their pursuers into disorder. Then they turned and made a stand. As they did so, the Janissaries, ‘Christians of origin, from many Christian nations,’ as Ducas bewails, came out of the place where they had been concealed, surprised and cut to pieces Frenchmen, Italians, and Hungarians. The pursuers were soon the pursued. The Turks chased them to the Danube, into which many of the fugitives threw themselves. The defeat was complete. Sigismund saved himself in a small boat, with which he crossed the river, and found his way, after long wandering, to Constantinople. The duke of Burgundy and twenty-four noblemen who were captured were sent to Brousa to be held for ransom. The remaining Burgundians, to the number of three hundred, who escaped massacre, and refused to save their lives by abjuring Christianity, had their throats cut by order of the sultan.[114] The battle at Nicopolis gave back to Bajazed almost at once all that the allies had been able to take from him. The defeat of Sigismund, with his band of French, German, and Italian knights, sent dismay to their countrymen and the princes of the West. In the same year, Bajazed gained successes over the Moslem prince of Caramania and a Turkish pretender at Sinope, rebels who had been induced to rise in the hope that they might take advantage of the attack of Sigismund and his allies. The sultan’s great object, however, was to complete his triumphs by the capture of Constantinople. His grand vizier had, in 1396, while blockading the city, urged the inhabitants to declare for the young Prince John, who was the Turkish _protégé_. On refusal, Bajazed sat down to besiege the city, and only abandoned the idea of an assault when it was pointed out that to do so would make enemies of all the Christian powers.
