The I. Bataillon and the 1. Grenadier-Kompanie of Infanterie-Regiment von Holnstein joined I. and II. Bataillon, and 1. Grenadier-Kompanie of Infanterie- Regiment von Pechmann to form the 1. Bayerische Kreis-Regiment (Infanterie-Regiment Kurbayern), which also had six 4-pounder battalion guns attached. The regiment missed the Battle of Rossbach, because it was detailed to Freiberg, Saxony, in 1757.
The soldiers of the combined Infanterie-Regiments Kurbayern continued to wear the uniforms of their parent regiments von Pechmann and von Holnstein. The picture shows an infantryman of IR von Pechmann, wearing a blue coat with straw facings, white vest and white trousers. Musketeers wore tricorne hats with yellow edging, grenadiers had bearskin caps with red bags. Officer's shabraques and pistol holster covers were in the facing colour, edged in the button colour.
