In 1444 he won the Battle of Linnich but was unable to prevail in his fight for Guelders and ultimately sold his claim to Burgundy and acquired Blankenheim-Löwenberg and Heinsberg from Guelders.
In 1813, Langeron was put in charge of the blockade of Thorn, and later that year he commanded a corps at Koenigswarte, Bautzen, Siebeneichen, Lowenberg, Katzbach, and Leipzig.
He was ordained in 1572, despite never having been to university, and served as priest and deacon in Kesseldorf, Löwenberg and Sprottau.
