Peter Freiherr Duka von Kádár (Serbian Cyrillic: Петар Дука; Esseg, Slavonia, 1756 - Vienna, Austrian Empire, 29 December 1822) was of Croatian Serb ancestry[1] privy councillor,[2] officer (Feldzeugmeister) and Inhaber of the Hungarian Infantry Regiment No.
In 1776 Duka joined the 13th Wallach-Illyrian (Romanian/Serbian) Regiment in Caransebeş as a cadet, but two years later, he was transferred to the General Staff as a Leutnant lieutenant for his obvious abilities.
He was able to communicate the main objectives to the Director of Artillery Oberstleutnant (Lieutenant Colonel) Karl Freiherr von Rouvroy and led the fourth division himself.
After further distinguished conduct at Wattignies on 15–16 October, followed by the battles of Berlaimont and Maubeuge, together with the sieges of Landrecies in April and Charleroi, he was rewarded on 1 May 1794 with promotion to Oberstleutnant (Lieutenant Colonel).
[7] In 1795 Duka was appointed Generalquartiermeister (Chief of Staff) to General Wurmser's Army of the Upper Rhine and he planned the successful attack on Mannheim, which was held by Pichegru's Armée de la Rhin-et-la Moselle on 22 November.
There he directed Feldmarschalleutnant (Lieutenant-General) Joseph Staader von Adelsheim's left-wing in the successful defensive actions during the victory at the Battle of Stockach on 25 March 1799.
[21] His granddaughter Anastasia (born 31 October 1828 in Belatincz, Zala County, Hungary; died 27 March 1907 in Graz) married Count Vincenz von Logothetti (1824–1886).
