The Rheinbund contingent

The contingents from each principality are composed of two companies that are amalgamated in a single battalion. This battalion takes parts in the 1807 campaign.
In 1808 each principality raises a single ad-hoc company that is sent to Metz in France to be reequipped and reorganized on French system

...and amalgamated with the contingents of Lippe, Reuß and Waldeck to form the famous “battalion of Confederated Princes”. This battalion is posted to Peninsular theatre of operation from April 1809.
In parallel, on April 2nd 1809 the Emperor decides the creation of six infantry regiments gathering the troops of the small German states. The contingent of Schwarzburg, three companies of Rudolstadt and three of Sonderhausen, forms the 1st battalion of the 6th Rheinbund Regiment that takes part to the Austrian campaign.
He is posted in Spain from March 1810. In June the battalion of Confederated Princes is disbanded and remaining strength absorbed by their national units. At the end of the year, the Schwarzburger battalion is reorganized in four companies, two from Rudolstadt and two from Sonderhausen.
At the beginning of 1811 the regiment returns in Germany to takes part to the invasion of Russia. Its remnants are then posted to the garrison of Danzig during the campaign of Germany in 1813. The same year, each principality raises two new companies that are posted to the garrison of Magdeburg.
