Kossova (Ottoman Wars).
Fought October 17, 1747, and two following days, between the Hungarians and Wallachians, 80,000 strong, under John Hunniades, and a vastly superior Turkish army, under Murad II. The Hungarians left their entrenchments to attack the Turks, and throughout the day the battle was evenly contested. On the 18th, however, the Wallachians deserted to the Turks, and the Hungarians, assailed in front and rear, were hard pressed, while on the 19th they were unable to maintain their position, and were forced to retire, defeated, with a loss of 17,000 killed and wounded. The Turks are said to have lost 40,000 men in the three days.
