, Vienna - Feldherrnhalle He was a lieutenant field marshal in command of the Silesian garrisons when in 1740
Frederick II and the Prussian army overran the province. His careful employment of such resources as he possessed materially hindered the king in his conquest and gave time for Austria to collect a field army (see
War of the Austrian Succession). He was present at
Mollwitz, where he received a severe wound. His vehement opposition to all half-hearted measures brought him frequently into conflict with his superiors, but contributed materially to the unusual energy displayed by the Austrian armies in 1742 and 1743. In the following campaigns von Browne exhibited the same qualities of generalship and the same impatience of control. In 1745 he served under
Count Traun, and was promoted to the rank of Feldzeugmeister. In 1746 he was present in the Italian campaign and the battles of
Piacenza and
Rottofreddo. Von Browne himself with the advanced guard forced his way across the Apennines and entered
Genoa. He was thereafter placed in command of the invasion of France mounted in winter 1746–7, leading to the
Siege of Antibes, but he was obliged to break off the invasion and return to Italy in February 1747 after Genoa rose in rebellion against the Austrian garrison he had left behind. In early 1747 he was appointed commander of all imperial forces in Italy, replacing
Antoniotto Botta Adorno. At the end of the war, von Browne was engaged in the negotiations on troop withdrawals from Italy, which led to the convention of Nice (21 January 1749). He became commander-in-chief in
Bohemia in 1751, and field marshal (
Generalfeldmarschall) two years later. ==Seven Years' War==
