The 1st Cuirassier Regiment of the "Grand Elector" Corps (Silesian Cuirassier Regiment) was a cavalry unit of the Prussian Army, founded in 1674 as the Guard Dragoons. In the 18th century, it was the mounted cuirassier regiment (K 4). It was disbanded in 1918 and is considered the oldest Prussian cavalry regiment of the 19th century.
World War I
The regiment was deployed in France as part of the 5th Cavalry Division, where it took part in the Battle of the Marne. In November 1914, the cuirassiers were transferred to the Eastern Front, where they were initially used mainly in Russian Poland and the Carpathians. In the summer of 1915, it was transferred to the Pripyat Marshes and the Pinsk region, where the troops remained until January 1918 and were used as cavalrymen in the dispatch and security service. The division was then disbanded. The cavalry regiments concerned surrendered their horses and were trained as infantry as part of the cavalry rifle units on the Zossen military training ground as part of the cavalry rifle associations. From July 1918 until the end of the war, the now 11th Rifle Commando fought in Champagne and took part in the heavy defensive battles of this section.
