The Dutch employed many Swiss units at various dates during the 17th and 18th centuries. In the early 18th century there were four regiments, and a ceremonial company of "Cent Suisses". They were mostly employed as garrison troops in peacetime, although the Republic sent Swiss regiments to Scotland in 1715 and 1745; in 1745, three battalions of the Swiss Hirtzel Regiment formed part of the Dutch contingent sent to serve in England as allies at the time of the Jacobite rising in Scotland that year. With the threat of a French invasion in 1748, four additional regiments were taken into service, but that year, the War of Austrian Succession ended and three of these additional regiments were retired from service. In 1749 a regiment of "Zwitsersche Guardes" ("Swiss Guards") was raised, the recruits coming from the ranks of the existing Swiss infantry regiments; in 1787, these six regiments numbered a total of 9,600 men.
