"Sebastian Peregrin Zwyer (of Evibach) (1597 – February 15, 1661) was a Swiss military commander, mercenary entrepreneur, and one of the foremost politicians of the Old Swiss Confederacy in the seventeenth century.
A native of the Swiss canton of Uri (he was probably born in Klingnau), Zwyer initially pursued a military career. From 1612 to 1617, he served in a mercenary regiment in the service of Spain and Milan; from 1619 to 1642 he was in service for the Habsburg emperors, first for Ferdinand II and then Ferdinand III. Zwyer fought in several battles of the Thirty Years' War. He participated in the Battle of White Mountain in 1620, fought at Glückstadt in 1624, at Mantua in 1630, and at Nördlingen in 1634." - (en.wikipedia.org 14.03.2021)
