 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.Cumberland's unpopularity, which had steadily increased since Culloden, interfered greatly with his success in politics, and when the death of the Prince of Wales brought the latter's son, a minor, next in succession to the throne, the Duke was not able to secure for himself the contingent regency.
