The Carignan-Salières was formed from two existing regiments: the Balthasar Regiment, formed during the Thirty Years' War and becoming the Salières when Balthasar died in 1665, and the Carignan Regiment, formed in 1644 in Piedmont [REF].
Four companies under Alexandre de Prouville joined the Carignan-Salières in New France from Martinique; de Prouville companies were attached to, but never formally integrated into, the Carignan-Salières [REF].
