In 1733, Lacy and Munnich expelled the Polish king, Stanisław I, from Warsaw to Danzig, which was besieged by them in 1734. Thereupon the Irishman was commanded to march towards the Rhine and join his 13,500-strong contingent with the forces of Eugene of Savoy. To that end his corps advanced into Germany and, meeting the Austrians on 16 August, returned to winter quarters in Moravia with exemplary discipline. In 1743 he commanded Russian forces at the Siege of Gdańsk in which French and Polish forces were defeated. Lacy led the Russians in two other decisive battles of the conflict, Wisiczin and Busawitza. In the latter battle he was outnumbered ten to one but nevertheless prevailed. For this victory he was awarded Order of the White Eagle. After Busawitza Lacy was ordered to reinforce the Austrians at Mannheim. however, when he reached Mannheim peace had been declared.
