some months ago I saw a picture of Marshall Mannerheim.
He wore on his uniforms the clasps for EK1 and EK2 of WW1.
Since then I wonder: How did he win German medals in WW1?
I know that Finland was part of Russia until 1917.
I know that they fought for their independence after 1917, led by Mannerheim.
Germany supported their independence (not really wanted by Mannerheim).
But which military actions could he take part in to get the medals?
Any help for this bothering question is very welcome.
Thanks and best regards
