Maximilian Ulysses Browne was of the first generation born in Austria but was from a prominent Limerick family. Through his mother he was descended from the FitzGeralds, Earls of Desmond. Browne was a major-general by the age of 30. He rose to the rank of "Generalfeldmarschall" and died leading his men into battle during the Battle of Prague. Browne was a kinsman and mentor to Franz Moritz von Lacy (son of Peter Lacy) who rose to be president of the "Hofkriegsrat" from 1766 to 1774. Other famous Irish-Austrian generals included William O'Kelly from Aughrim in Co. Galway; John Sigismund Maguire of Co. Kerry, who captured Dresden in 1758 and successfully defended it against Frederick the Great, who mentioned him on a number of occasions; and General Karl O'Donnell, was known for his exceptional conduct at the Battle of Torgau. Meanwhile, Colonel Hume Caldwell of Co. Fermanagh was noted for his conduct at Breslau and Olmütz, where he perished. Unusually, Caldwell was of Protestant origin. Field Marshal Laval Nugent von Westmeath was prominent during the Napoleonic Wars and was most noted for his role in the capture of Rome in 1815. In recognition of this, Pope Pius VI made him a prince in 1816. There were no Irish regiments in the Austrian Army with influence confined to nobility serving as officers.
