In 1387 after there had been such successes of the Turks to record as the surrender of Monastir, and Prilep, and Schtip, and even the temporary seizure of Thessalonika, the Servians undertook, under the direction of a feudal lord, Lazar, to organize a systematic plan of resistance. Lazar was first aided by a Bosnian king, Tourtko, who had, however, ambitious designs on certain lands under the Hungarian crown, designs that soon robbed his promised co-operation of its influence. Schischman of Bulgaria was drawn into the league, and in Lazar’s army there appeared also contingents of Albanians and Roumanians standing side by side with the Slavs. The crisis was fully appreciated by Murad. He summoned new troops from Asia, and all the greatest generals took part in the campaign, in addition to his two sons, Bajesid and Jakab. The decisive battle was fought on ground that was part of Lazar’s own domains near Prischtina, on the wide plains called Kossowopolje. Murad was surrounded by his band of Janitschars; to hold back the enemy the camels of the Asiatic troops were drawn up in front. The Christians were confident in their superior number, for they had 200,000 men under arms ready to begin the attack. From a contemporary account comes the narrative of the death of the Sultan. It is there told how ten young men of distinguished birth, bound by oath to stand by one another, succeeded in forcing their way to the tent of Murad. One of these, Mulasch Obilitsch, managed to inflict two fatal wounds on the neck and body of the aged ruler. But this successful stroke did not end the fight, for Bajesid, who was renowned for the rapidity and daring of his generalship, drove his wing of the Ottoman army into the Christian ranks, broke through them, and put them to flight at the very moment they thought themselves victorious. It is said that in the panic Lazar lost his life; probably he was captured and subsequently sacrificed in revenge for the murder of Murad. (June 15, 1389.)
