I am looking for information on Friedrich Carl Gustav August Krieg's participation in WW1 on German side.

He was born in Nohra near Weimar in 1900. He is said to have had the rank of Ober- or Gefreiter.
He was wounded in the lower jaw but survived.

Any info on which regiment he belonged to - where they fought battles etc etc is greatly appreciated.

Regards,
Laila Mikkelsen
