John, I appreciate that the original purpose of this thread was to find more details of the RAF aircrew and how they came to die. But since Signalman Roberts's story seems to be inextricably tied to their deaths, or at least their burials, it seems to me to be sensible not to split the thread at this stage.
I am confused as to why Sig Roberts's remains are so hard to identify. If he had both legs amputated, his remains would be very different to the unknown airman, whose body was presumably fairly intact at the time of his death. I appreciate that you may have no more knowledge about this aspect than I do, but surely when Roberts was buried he should have still had his dog tags on his body, since he had already be admitted to hospital. Even given the haste in which the British medical staff had to leave, I can't believe that adequate identification was not left with the bodies. I am convinced that the CWGC can and should do more to positively identify Roberts, and by extension the remains of the missing airman, and mark their respective last resting places in a fitting manner.
Added. I agree with your translation of the relevant passage from the book.
