A few days ago I read your information about your father and hopefully you will get this message after this years.
My uncle, first stationed in Jüterbog (2. Batterie Beobachter Ersatz 6, from 30.09.41 to 31.10.41, moved to France where he has been from 01.11.41 until 09.05.44.
He also was in a "leichte Artillerie Ersatz Abteilung", "Wetterpeilzug 335 later 509" and "Beobachter mot". He took part at Artillerie Schule II for Fahnenjunker in Suippes/Mourmelonn, Marne, France. His Feldpost number than was 58281 D/Lehrgang II und 1. - 6. Lehrgang für Fahnenjunker of Artillerie., from 12/1942 ? until 03/1943). During his time in Suippes/Mourmelon (Mourmelon = schwere Artillerie) he was at the 6. Batterie Artillerie-Lehrregiment 3. Thats out of the files from Bundesarchiv PA Berlin.
But During his school he was from August 1943 until December 1943 in Russland in Stabsbatterie Beobachtungsabteilung 44 and later 67.
From January 1944 until Mai 1944 he again took part in this training in Suippes.
I guess he was somewhere stationd in France near Dijon, Suippes/Marmoulon and later near Marseille. Have you got any letters or photograph left from your father?
