The Saint Anne's Medal For Soldiers.

[EricFG]

The St. Anne's Medal for Soldiers was a separate medal for enlisted men and NCOs. Evidently the Order of St. Anne was for officers and dignitaries. Foreign military personnel also received St. Anne's Medals for action in service to Russia during WWI, showing up among both Allied and German soldiers' awards. Evidently it was serial numbered.

Examples of the St. Anne's Medal. Note the serial number on the reverse of the medal in the upper right of the image.
This medal should not be confused with the Red Cross medals issued as the St. Anne's Medal has a Maltese-type cross on the obverse as opposed to the straight arms of a typical 'Red Cross' item.
