Yeah well m.m. its certainly true that memoir written from memory can make factual errors..
But some of Spurdle's stuff is straight from his log-book, as written at the time..
& for sure, you weren't there..
For all you know m.m., 'Judy's' claims might've been credited to flak..
There were instances of Allied flak units being given claim precedence - for 'morale' reasons..
Historians - years after the fact- & even official service-written historical documents can get things wrong too..
Especially if there is a downright embarrassing episode that needs a cover-up..
There are Brit WW2 documents - that are still hidden - under the 100 year rule too.
A lovely bit of bogus 'struck off-charge' paper-work bumf - is just the ticket - to hide the true situation..
Just look up the Allied B.S./Secrecy cover-up over another embarrassingly damaging LW air attack,
that on Bari, in Italy a bit over a year earlier..
Or the false loss reports written & applied to 'friendly-fire' incidents & covert ops - that went bad..
Not so much 'fog of war' .. as deliberate B.S./smokescreen..
As evidence for one of his experiences, -an HO attack that put a hole through one his Spit's prop blades..
'
Ol' Bob kept the blade, to show anyone who called 'scuttlebutt'/B.S. on him about it..
Last I saw it, it was in the Kiwi Fighter Pilot Museum in Wanaka, NZ...
