That book appears to be more fiction than non.
I disagree. Now that I have all three volumes of Shores's book on 2nd TAF, I find that none of the events in Clostermanns' book is pure fiction. At least I cannot prove that.
There are errors in names, victories, losses, exaggerations etc, which is understandable. Shores himself wrote that the 2nd TAF loss data is incomplete, especially regarding the planes.
I'll post some of the encounters later. Stay tuned.
