The pass is quite interesting, he first saw frontline duty in (Bayr) R.I.R.16 from mid 1915 onwards until he got in mid 1917 a transfer to I.R.2 after recovering from his wounds he sustained at the Somme.
He was wounded 17.7.1916 at Fromelles.
After recovery he was sent to the Somme and was wounded 12.10.1916 at La Barque (7 days after Adolf Hitler was wounded).
Recipient of the E.K.2.
Reason I post first the picture of his transfers is that it was not obvious on the sales description neither the stamps he served in RIR 16 the majority of his war, but is clearly visible in his transfers and wounds as well in his combat chronicle from RIR 16.
The entries seem to be mainly from the time he was in I.R.2. by the looks of the dates when the entries have been written.
