Origin and History

In December 1760, Frederick II instructed Major Quintus Icilius to raise 7 new Frei-Infanterie battalions. The battalion was raised in Halle on January 6 1761, mostly from deserters from the Swiss regiments in the French service. For this reason it was also known as the “Volontaires de Suisse. This battalion, consisting of 2 companies of musketeers and 1 company of grenadiers, was placed under the command of Heer. All officers came from Glarus in Switzerland, a canton who had a personal union with Prussia.

According to Bleckwenn's classification system, the unit is designated as “Frei-Infanterie Regiment F12”. The unit consisted of one battalion of:

  • 2 musketeer companies, each of:
    • 4 officers
    • 7 NCOs
    • 1 drummer
    • 1 fifer
    • 150 privates
  • 1 grenadier company of:
    • 4 officers
    • 7 NCOs
    • 2 drummers
    • 150 privates
  • 2 x 3-pdr guns.

During the Seven Years' War, the unit was under the command of:

  • since January 6 1761 till 1763: Major Nikolaus Heer

In 1763, at the end of the Seven Years' War, the battalion was incorporated into the Bülow Fusiliers.

Service during the War

In the Spring of 1761, the battalion was attached to the corps operating in Saxony under the command of Prince Henri. On October 1 near Osterwick, the battalion was surprised by the Volontaires de Saint-Victor who took most of its troops prisoners. However, the battalion was soon reconstituted.

For the campaign of 1762, the battalion was once more attached to the army of Prince Henri operating in Saxony. On June 1 at Grumbach, most of the battalion, along with its commander was taken prisoners. In the Autumn, its ranks were replenished and a third company of musketeer added.
