Peter Karl Ott von Bátorkéz (1738 – 10 May 1809) joined the Austrian army and fought in the wars against the Kingdom of Prussia, Ottoman Turkey, and the First French Republic in the last half of the 18th century. During the French Revolutionary Wars, he rose in rank to general officer and twice campaigned against the army of Napoleon Bonaparte in Italy. He played a key role in the Marengo campaign in 1800. He was Proprietor (Inhaber) of an Austrian Hussar regiment from 1801 to 1809.
Born in Esztergom (Gran), Hungary in 1738, Ott joined Andlau Infantry Regiment # 57 as a Fahnrich (cadet) in 1757. He was a veteran of the Seven Years' War, having fought at the battles of Landshut and Liegnitz, being wounded in the latter action. In the War of the Bavarian Succession he served in the Kálnoky Hussar Regiment # 2 as a Major. While still serving with the Kálnoky Hussars as the Oberst-Leutnant, he led his horsemen in numerous actions during the Austro-Turkish War (1787-1791). After directing the hussars in a successful action at Valje Muliere, he earned promotion to Oberst (colonel) of the regiment. He was awarded the Military Order of Maria Theresa for an action against the Turks at Calafat, Wallachia in modern Romania. In 1791, he was elevated to the noble rank of Freiherr.
