Revolution, and took up positions in front of the ruler's residence. On 30 June 1848, the first commoner, Jakob Ermarth, was appointed Colonel-Commandant. 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. War against Prussia In 1866 in the Austro-Prussian War, with Bavaria fighting on the Austrian side, the regiment was not deployed as a whole; the I battalion was stationed in the fortress of Mainz, whilst the II and III battalions, under Colonel Siegmund von Pranckh, were assigned to the 1st Royal Bavarian Infantry Brigade. After 4 battles, the regiment counted 17 dead and 136 wounded, with the Colonel having been replaced, unusually, by the non-aristocratic Adalbert Högenstaller already after the first of these battles (at Nüdlingen). Franco-Prussian War In the Franco-Prussian War the whole regiment was assigned to the 1st Brigade, and thus to the 1st Division. At Lechfeld, it counted 66 officers and 2879 men ready for action. In the battles of Wörth on 6 August 1870 and Sedan on 1 September the regiment was at the centre of the fighting and suffered a few casualties. For the actions at Sedan the commander of the III battalion, Major Joseph Graf von Ioner-Tettenweiß, was awarded the Knight's Cross of the Military Order of Max Joseph. After the battle at Artenay on 10 October 1870 the regiment occupied Orléans on 11 October, but had to give it up again on 9 November 1870 in the face of far superior French forces, the Armée de la Loire. 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. He was also awarded the Knight's Cross of the Military Order of Max Joseph. On 2
