In late 1757, the Army of Germany began forming under the command of Marshal Louis Charles César Le Tellier, Duke of Estrées in preparation for the coming invasion of Westphalia and the North German Plain. That year, the army crossed the Rhine river and saw action at the Battle of Hastenbeck and soon after conquered all of the Electorate of Hanover. In 1758, the regiment along with the army was destroyed at the Battle of Krefeld, and retreated back across the Rhine. Following the disaster, the regiment was sent to Vassy to recruit and recover. In 1761, the regiment moved back into the front lines at the Battle of Mulhausen and was present at the Battle of Limburg. In 1762, the regiment was back in Germany campaigning with the new army, but no actions of note occurred.
