For most of the 18th century, the Brigade was used to man the Dutch Barrier forts. In the War of the Austrian Succession, detachments fought at Fontenoy, Rocoux and Lauffeld and held Bergen op Zoom during the 1747 siege. After it fell to the French, the garrison withdrew to Steenbergen, which they successfully defended until the war ended in 1748; by then, only 200 officers and men of the original 800 remained. It is likely some men under Alexander Marjoribanks stayed at Loevestein Castle between 1750-1754 where there is a fresco depicting Lord George Murray (general), his wife, son and a piper.
