This beautifully enameled award is a bit outside the focus of this thread as it is post-war. But since it has a very direct link to a well-known regiment of the Imperial German Army that saw a lot of action in WW 1, I thought it might be of some interest. If it's inappropriate, let me know and I will delete it.
Ehrenzeichen der Freiwilligen Hundertschaft Krose
(Badge of Honor for Volunteer 'Company' Krose - It's difficult to precisely translate "Hundertschaft" as it's an old German military term for a unit roughly the size of a company of 80-100 men, based on ancient Germanic tribal formations which themselves were modeled on the Roman 'Century'.
Freiwillige Hundertschaft Krose was formed by Oberleutnant a.D. Wilhelm Krose from former members, primarily officers and senior NCOs of Infanterie-Regiment Bremen (1. Hanseatisches Nr. 75) when the 3rd Polish uprising in Upper Silesia began on May 3, 1921. It participated in the defence of the city of Pitschen, the fighting at Kostau and Seichwitz and on May 24-26 it participated in the storming of the Annaberg Mountain.
The award was given by Oberleutnant a.D. Krose for those who had distinguished themselves principally in the defense of the city of Pitschen, as well as the storming of Annaberg and other associated struggles in Upper Silesia. Awards were manufactured by Heinrich Timm, Berlin based on a design by Krose. The central medallion shows the red and white stripes of the ribbon of the Bremen Hanseatic Cross in honor of the wartime service of Krose and his men in Infantry regiment Bremen.
The exact number of awards or crosses manufactured is not known. However, since this Freikorps only formed the 3rd Company of Selbstschutz-Bataillon Pitschen from the city of Pitschen in Upper Silesia, it’s generally believed that only around 100 crosses were awarded.
