That association of mountainous territories shut in among the European powers, Switzerland solved part of its financial problems as early as the Renaissance by developing a truly mercenary industry. Each canton could sign a contract (a capitulation) to recruit military units with their own officers and regulations in exchange for pay and equipment for a neighbouring state. On the eve of the Revolution there were therefore Swiss units in the government guards or the troops of the Line in France, the Italian States, Spain and the United Provinces. During the vast European reorganisation led by France between 1793 and 1813, Switzerland was politically and geographically transformed and furnished its big neighbour whether it liked it or not with troops of great worth who upheld their favourite motto "Honneur et Fidelite". Much has already been written on the Swiss regiments. The book skims over the Swiss troops in service with the King on the eve of the Revolution to concentrate on those who served the Republic, the Consulate and then the Empire, focusing on less well-known aspects.
