Peter Henn = Alfons Schertl?

[kaki3152]

One of the Luftwaffe books I bought in my youth was "The Last Battle" by Peter Henn. It was a standard Luftwaffe fighter pilot, similar to " I fought You From the Skies".
The setting of the book was the Mediterranean, and from certain clues, the unit was determined to be II/JG-51. One great picture in the version I have, which is falling apart, is that of Hptm Herbert Puschmann at Lavariano A/F.
In the book, he is then transferred to the Ground attack force, only to be shot down at the end of the war.

Peter Henn is clearly a pseudonym, and some correspondence led me to believe his real name was Alfons Schertl.

I found this in Doug Starkey's LW officer data base

SCHERTL

, Alfons. (DOB: 15.04.20). 01.42 at Zerstörerschule 2. 10.42 trf to III./ZG 26 then to 2./NJG
5. 02.43 at JFS 2 (Zerbst). 05.43 trf to Erg.JGr. West. 21.06.43 trf to 6./JG 51. 02.44 Staka 6./JG 51.

23.04.44 WIA. 19.10.44 trf to SG 151. 14.11.44 Oblt., trf to 9./SG 4.

The units fit, 6./JG-51 and SG-4 later in the war. This is the same guy,right?
