Thanks for the information about the correction location. NSG 9 was involved in Wallenstein II but not (as far as I know) in Wallenstein III.
I have the 600 Squadron combat reports but there was no online coordinate converter (or Google Earth) when I wrote the book, so I was measuring as best I could from a USAAF pilot's map. Jefferson and Spencer's report said that their victim crashed at "R.1727" but the one from Crooks and Charles does not give a map reference, just "Leghorn [Livorno] area."
On the North Italian Grid, wR1727 = 43° 24' 32'' N / 11° 44' 24'' E, about 2.4 km west of Le Poggiole (AR).
Since I wrote the book, I have been able to establish that
Fietz and Rasinski were shot down on 3/4 August and both survived (but with bad injuries). Fietz said that Krüger and Tschirsch were shot down the same night. That leaves Wolfsen and Wilk as the only known losses on 2/3 August, although I have two RAF claims that night.
