Thanks PETER!
But I guess I did not expressed myself correctly.
I would like to understand IF early in the war the aircrew were credited with U-Boat victories ONLY by their reports?
AND...if later, by 1943 forward, there was any kind of "cross-checking" the information submitted by the RAF, Coastal Command, etc.. aircrew x ( versus ) known losses intercepted by ULTRA?
As I wrote, some aircrew were credited with U-Boat victories without actually sending them to the bottom...that´s what I am trying to understand: the CREDIT of those claims...
Thanks for your post about a Polish claim. Was it verified by ULTRA or another source?
Yours
Adriano
