According to the Serbian songs, whose testimony the Byzantine historians corroborate, and whose story has been followed by some Osmanlis as well, Murad was assassinated after the battle, or perhaps while the battle was in progress, by Milosh Obravitch. Stung by the unjust accusation of treason in the speech of Lazar on the eve of the battle,[420] Milosh determined to prove his loyalty beyond any question. He got through the Ottoman ranks as a deserter, of whom there must have been many on that fatal day. His claim of high rank, which was attested by his princely bearing, secured for him an audience with Murad. When he was face to face with the emir, he plunged his dagger into the destroyer of his country’s liberties. It is a commentary on the Serbian character that this questionable act has been held up to posterity as the most saintly and heroic deed of national history. In the seventeenth century it was believed, and this belief has been reproduced as a fact by some modern writers on the Ottoman Empire, that the custom of holding a foreign ambassador’s arms when he entered the presence of the sultan, originated from a regulation to prevent the recurrence of such a crime.[421] Like many other Ottoman customs, however, this consistorial ceremony is found among the usages of the Byzantine court,[422] and has persisted in some oriental courts to the present day. It has been explained on the ground that ‘a stranger before the sovereign is so overwhelmed by the effulgence of his rays that he cannot stand without support’.[423] The statements of the numbers engaged in the battle of Kossova are so conflicting that it is impossible to determine how many men took part in the action, or which side was the stronger. The Serbian folksongs dwell upon the tremendous number of the enemy, while the Ottoman historians report that the Osmanlis mustered so few in comparison with the reported strength of the Serbians that there was serious question before the battle of the advisability of taking so great a risk as to engage a foe whose numerical advantage was so marked. Including the prisoners, who were massacred when Murad’s death was learned by the soldiers, the Serbians calculated their loss at seventy-seven thousand killed, while only twelve thousand of the Osmanlis fell. One important fact we do know. The loss of life during the battle and subsequent massacre on the part of the Serbian nobility was so great that the nation, for the third time within thirty years, found itself without leaders.
