Immediately after the death of Maximilian I Joseph, his son and heir Ludwig I decreed the abolition of the expensive Guard regiments.
The 1st and 2nd battalions were transferred on 5 October 1848 to Sigmaringen in Marsch, to protect Charles, Prince of Hohenzollern-Sigmaringen and to depose the provisional government there.
After similar deployments under an "observation corps" in the area of Ulm and Günzburg, the battalions returned by 31 December 1849 to Munich.
For the regiment's 50th anniversary on 16 July 1864, its officers and the Colonel-Commandant Karl Graf von Spreti held a banquet in the Hotel Vier Jahreszeiten in Munich, and its non-commissioned officers and enlisted ranks received an allowance of 500 guilders from King Ludwig II, and 100 guilders from Prince Otto.
The cautious but brave actions of Captain Karl Hoffmann, head of the 9th Company of the regiment, in the Battle of Villepion on 1 December 1870 prevented a breakthrough by superior French units, and held the endangered position until the end of that day.
On 2 December 1870, the regiment proved itself in the bloody Battle of Loigny-Poupry, for which First Lieutenant Hermann Ehrne von Melchthal (8th Company) received a Knight's Cross for bravery in the face of the enemy.
On 7 December 1870 Second Lieutenant Friedrich Krieger, head of the 11th Company, repelled an attack by superior French forces on an artillery unit at Lemons (near Meung) and engaged in a counter-attack on his own initiative.
On the same day Second Lieutenant Alfred Meyer distinguished himself through his brave actions in a battle at Le Bardon (north-west of Meung), resulting in the award of a Knight's Cross on 24 May 1871.
