William Wilkinson, An account of the principalities of Wallachia and Moldavia (1820)
“ The Wallachians under this Voïvode joined again the Hungarians in 1448, and made war on Turkey; but being totally defeated at the battle of Cossova, in Bulgaria, and finding it no longer possible to make any stand against the Turks, they submitted again to the annual tribute, which they paid until the year 1460, when the Sultan Mahomet II. being occupied in completing the conquest of the islands in 19the Archipelago, afforded them a new opportunity of shaking off the yoke. ”
