After the campaign in Greece, Murad marched northwards to attack the Albanians, and endeavoured to capture Kroya,[155] the capital of the country. But it was held by the Albanian leader, George Castriotes, whom we have already met under the name of Iskender (or Alexander) Bey, a man who was a military genius, and who in some respects recalls the adventures and characteristics of Garibaldi. But he was unscrupulous as well as energetic. Devoting himself like a new Hannibal to the salvation of his country, he held and continued to hold absolute, but willingly rendered, sway during twenty-five years over the Albanian mountaineers. Christian by birth, but given over with his brothers to the Turks as hostages, and forcibly converted to Mahometanism, he had become a favourite of Murad for his handsome appearance, his strength of body, and his courage. He had gained power over his countrymen in the first instance by a ruse as bold as it was relentless. Scimitar in hand, he offered as an alternative to the reis-effendi, or commander-in-chief, either immediate death or the affixing of his signature and seal to a document ordering the governor of Kroya to hand over to him the fortress and the adjacent country. Having obtained the document in due form, he then killed the reis-effendi. At this time Iskender Bey was only nineteen years old. Gathering a small band of Albanians about him, he hastened across the peninsula and obtained possession of Kroya by a stratagem even more desperate and dangerous than that by which he had obtained the order for his appointment as Turkish governor. Leaving his followers outside the city and in hiding, he presented his credentials and obtained the keys of the fortress. During the night, he personally admitted his followers, and the Turkish garrison were murdered while they slept. Then he rapidly made his preparations for defence against the attack of Murad which he knew would follow. It is sufficient for our purpose to say that he was successful, and that at the approach of the winter of 1447–8, Murad’s attempt to recapture Kroya entirely failed, and the great sultan withdrew to Adrianople.

Meantime the Christians north of the Danube were preparing to make a greater effort than ever to strike at the power of the sultan. The new pope, Nicholas the Fifth, urged the duty of aiding the Hungarians and the Poles as vigorously as his predecessor. But his appeals to other states were of little avail. Hunyadi, notwithstanding the defeat at Varna, was named lieutenant-general of the kingdom almost immediately on his return, and at once set himself to reconstruct an army. In less than four years he possessed the best-disciplined host which Hungary had yet seen. But it was far too small for the purpose on hand. Among its twenty-four thousand men were two thousand German arquebusers and eight thousand Wallachians. With this force Hunyadi crossed the Danube near Turn-severin and invaded Serbia, because its ruler, whose sister was married to the sultan, refused to break the engagement with Murad.

When the sultan, who was preparing for another attempt to defeat Iskender Bey and the Albanians, heard that George of Serbia was on the point of being attacked, he at once made all haste to go to his assistance. Hunyadi encamped near Cossovo, on the same Plain of Blackbirds where, in 1389, Murad the First had been assassinated after his victory. The Turkish army, probably numbering a hundred and fifty thousand men,[156] occupied three days in crossing the Sitnitza, a small river which runs through the plain into the Vardar. Hunyadi, for some reason which is not evident, left his entrenchment and crossed the stream, apparently with no other object than of forcing on the fight. Why he should have done so, since he was hourly expecting the arrival of a detachment of Albanians under Iskender Bey, it is impossible to understand.

Second battle of Cossovo-pol, 1448.

The battle commenced on October 18, 1448. The Turks were drawn up in the same order as at Varna, the Janissaries in the centre surrounded by a trench, behind which were ranged the camels, and behind them again a belt of shields or bucklers fixed in the ground. To the right of the Janissaries was the European, and to the left the Asiatic, division of Murad’s army. On the other side, the centre of the Christian army was occupied by the German and Bohemian arquebusers and some of the best troops of Transylvania. The right wing was formed of Hungarians with a few Sicilian auxiliaries, while the Wallachs were on the left.

The first day’s fight was not general. But at noon on the second, the whole lines on both sides were engaged, and continued till sunset, when, in spite of the superiority in numbers on the Turkish side, no advantage had been gained. Hunyadi, indeed, believed that during the night his enemy intended to break up his camp and commence a retreat. For this reason, he determined upon a night attack—one of the measures, as General Skobeleff testified after fighting in Central Asia under somewhat similar circumstances, in which the best-disciplined army almost necessarily wins. All the valour of the Hungarian army was powerless to break through the line of the Janissaries, and the attack consequently failed. On the morning of the third day, the fight was again renewed, and victory appeared doubtful. But the Wallachs turned traitors, and in the midst of the fight, their leader having obtained terms from Murad, passed over to the Turkish side. The army of Hunyadi was now attacked in front and rear, but contrived to reach its entrenchments. Judging that its condition was hopeless, Hunyadi made his escape in the evening, leaving the Germans and Bohemians to hold the central position of his encampment. This they did with magnificent courage, but the battle was already lost. Out of the army of twenty-four thousand, seventeen thousand men, including the flower of the Hungarian nobility, are said to have been left dead on the field.[157] But the victory had been dearly bought by Murad. During the three days’ fight, forty thousand Turks had fallen.[158]

The Christians had lost the battle through the rash courage and confidence of their leader. Hunyadi had refused to wait for Iskender Bey and his Albanians, had abandoned a strong position in order to attack an enemy largely superior in numbers, and his desertion of the best of his auxiliaries is inexplicable or unjustifiable. The defeat at Cossovo-pol, following that at Varna, made men forget for a time the series of brilliant victories which the great Hungarian had gained over the Turks in Transylvania and elsewhere. But in the glorious defence of Belgrade against Mahomet after the capture of Constantinople, Hunyadi recovered greater reputation than ever, and the West recognised in that city the first bulwark of Christendom, and in its defender the greatest soldier of the age.[159]

The effect in Hungary and Constantinople of these victories of Murad was appalling. The sultan and his successors for many years had nothing to fear from the enemy north of the Danube.

Reasons for failure of Western attempts against Turks.

The great combined efforts of the West to break the Ottoman power and, incidentally, to save Constantinople had failed disastrously. Nor are the reasons for such failure difficult to understand. They are mainly two: underestimating the power of the enemy, and dividing their own forces. First and above all, neither the pope nor the statesmen of Europe had realised the enormous number of fighting men which the Turk could bring into the field. They knew that the empire of Constantinople had been dismembered by Turkish armies, but they attributed this loss to secondary causes, and do not appear to have realised that Turkish armies beaten again and again constantly reappeared. The empire’s loss, in their opinion, was due to the incapacity of some of its emperors, to civil war, to the pressure of Serbia and Bulgaria, and to the judgment of Heaven upon the Greeks for having refused to come within the one Christian fold, and to acknowledge the one shepherd. The Turks were the instruments of divine justice to punish schismatics, but, having done their work against the empire, they would, now that they ventured to attack Catholic states, no longer be permitted to make further encroachments.
