In August 1757, the 2. Bavarian Kreis-Regiment consisted of four infantry companies recruited in the Bishopric of Salzburg. When the Battle of Rossbach was fought on 5 November 1757, the regiment stood at Nuremberg, Franconia. In May 1758, IR Salzburg had reached a strength of nine companies, organized in two battalions of four companies each, plus one grenadier company. In addition, the regiment had three battalion guns.
From December 1759 to February 1760, the I. Bataillon and the grenadier company were at Hof, Upper Franconia, while the II. Bataillon was quartered at Lichtenberg and Naila. During this time, the regiment was engaged in Small Wars skirmishes with Prussian irregular Freitruppen, in the course of which several battalion guns were apparently lost. In 1760, the regiment received new battalion guns with red carriages. In December 1760, IR Salzburg and IR Kurtrier were quarter at Hof. The I. Bataillon marched to Münchberg on December 15, followed by II. Bataillon on 18 December 1760. At the Battle of Freiberg, 29 Oktober 1762, the regiment fought on the right flank of the imperial Reichsarmee, under General-Leutnant von Rosenfeld.
