The writing at the bottom of the first image says:
am 21.5.41 verstorben Kriegsgefangen-
lager Chania auf Kreta
Grablage: 600 m südstr. Adele/Rethymnon Olivenhain
Umgebett. a. 5.1.43 Engl. Sammelanlage Grab Nr.56
Died 21/5/41 at Chania PoW Camp on Crete.
Grave location: 600 m [along the] south road from Adele to Rethymnon [in an] olive grove.
Reinterred on 5/1/43 at the British concentration cemetery, grave No.56
The handwriting above, where you've written GOLD, is his rank Sold[at] = Private.
The other side is just administrative notes listing the units and offices that the various reports came from and where they were filed - lots of difficult abbreviations there which I don't know the meaning of.
Hope this helps!
