Following the defeat of Marignan in 1515, the signing of the perpetual peace with France in 1516 and the conclusion of a treaty of defensive alliance between France, the Swiss cantons and their allies in 1521, including Valais, mark the beginning of the foreign service. Valais commits, in this context, to purvey the King of France with a certain number of soldiers; in exchange, the King of France pledges to pay rich pensions and to provide Valais with a supply of salt. The de Courten regiment which remained in the hands of the same family from 1690 to 1792, is the most famous and well documented regiment of Valais. As a testimony this certificate of dismissal and passport was issued by Pierre Christophe François de Lavallaz, "commander of the 3rd battalion and captain of a company from the de Courten infantry regiment of the Republic of Wallay in Switzerland", in favour of Georges Bonaventure Gillet from Sierre who served him "for six years as soldier and six years and six months as sergeant".
