Nevertheless, the Brunswick Oels Jägers gave a good account of themselves during the war. The regiment — really a single battalion—arrived in Portugal in early 1811. The Duke of Wellington distributed one company to the 4th Division and two companies to the 5th Division as skirmishers, while the remaining nine companies served in the newly formed 7th Division. The Oels remained in this organization until the end of the war in April 1814. During this period, the Oels served in most of the major battles including Fuentes de Onoro, Salamanca, Vitoria, the Pyrenees, Nivelle, the Nive, and Orthez.
