The Jäger-Bataillon Nr. 8, also known as the “Achter” (Eighth) or “Deutsche” (German) Jägers, was an elite light infantry unit of the Austrian Imperial-Royal Army. It was formed by men recruited from the German-speaking provinces of Inner Austria, and its primary role was that of a light-infantry skirmisher. The battalion’s troops were highly trained in reconnaissance, sharpshooting, and fighting in open, broken terrain. Due to their specialized skills, they were often deployed as an advance guard or flank screen to protect larger infantry formations. The unit was commanded in 1809 by Oberstleutnant Hieronymus Mumb.

As you would expect from a Jaeger unit the battalion’s appearance distinguished it from the line infantry. They wore a pike-grey coat with steel-green facings and black trousers. Their unique headgear was the “Corsican hat,” a black top hat-style hat with one side turned up. This simple, yet effective, uniform allowed them to blend into their surroundings more easily than the more brightly-colored line infantry. The Jäger’s marksmanship was legendary, and those who proved to be exceptional shots were awarded green tassels and cords on their left shoulder. This recognition of skill underscored the unit’s emphasis on individual proficiency.

In 1809, the Jäger-Bataillon Nr. 8 was commanded by Oberstleutnant Hieronymus Mumb. His career progression within the Austrian Imperial-Royal Army demonstrates a series of promotions and assignments, particularly within the General Quartermaster Staff.

Hieronymus Mumb was promoted to Major in 1799. In 1805, he was appointed to the position of Oberstleutnant. Later that same year, he was advanced to the rank of Oberst (Colonel) and given command of the Infantry Regiment Hohenlohe-Bartenstein Nr. 26. He was further promoted to General-Major on August 31, 1809, shortly after his service at the Battle of Wagram.

Mumb continued his military service, commanding a brigade at the Battle of Leipzig. His career culminated in his promotion to Feldmarschallleutnant in 1824 and his appointment as the commander of the fortress of Temeswar in 1827, a position he held until his death in 1832.

In the 1809 campaign of the War of the Fifth Coalition, the Jäger-Bataillon Nr. 8 was attached to the I Corps of the Austrian army. They were heavily engaged in the decisive Battle of Wagram in July 1809. As part of Brigadier Frelich’s brigade, they fought fiercely against French forces, including the Imperial Guard.

Their actions during the battle, particularly an attack on a French Guard unit, earned two of their soldiers, Oberjäger Finkenberger and Unterjäger Schasser, the prestigious gold medal for bravery. Beyond Wagram, the battalion also participated in skirmishes and engagements in places like Ratisbon and Hirschau, demonstrating their continuous involvement and importance throughout the campaign.
