When the king died in 1740, the regiment consisted of 3,200 men. However, his successor Frederick the Great did not share his father's sentiments about the regiment, which seemed to him an unnecessary expense. The regiment was largely disbanded and most of its soldiers were integrated into other units. The regiment itself was downgraded to a battalion (Garde – Grenadier No. 6) and employed during the War of the Austrian Succession at Hohenfriedberg in 1745 and at Rossbach, Leuthen, Hochkirch, Liegnitz, and Torgau throughout the Seven Years' War. The battalion surrendered near Erfurt and Prenzlau after the Prussian defeat at the Battle of Jena-Auerstedt in 1806 and was disbanded.
