[On the demise of King Marko and Konstantin Dragaš]
After this, the proud and magnificent [Emperor Bayezid] conceived a war against the Hungro-Wallachians; and having risen with all his forces, he came and having crossed the Danube in 6903 [1394], they clashed in battles with the great and autocratic voivode Jovan Mircea, in which an unspeakable multitude of blood was spilled. Then perished King Marko and Konstantin. And there, in this battle, was also Prince Stefan, of whom we speak. For all these were with the Ishmaelites, if not by [their own] will, then by necessity, so that it is said of the blessed Marko that he told Constantine: “I say and pray to the Lord to be a helper to Christians, and let me be the first among the dead in this war.” [Indeed, in this testimony of Konstantin the Philosopher, many seek the roots of the great popularity of Marko Kraljević in the South Slavic oral tradition.] Returning to his home, the emperor [Bayezid] made peace with them.
