The Duke took no part in the Flanders campaign of 1746, during which the French made huge advances capturing Brussels and defeating the Allies at Rocoux. In 1747, Cumberland returned to the Continent and he again opposed the still-victorious Marshal Saxe and received a heavy defeat at the Battle of Lauffeld, or Val, near Maastricht, on 2 July 1747. This and the fall of Bergen-op-Zoom compelled the two sides to the negotiating table and in 1748 the Peace of Aix-la-Chapelle was concluded and Cumberland returned home.
