Do you also regret the offence you caused to British readers, Mr Grogan? Or did you mean to insult the Brits? It's a dumb-ass comment, if you don't mind me saying so.
If you knew anything about the so-called Battle of Barking Creek - which clearly you do not - you would know that it occurred very early in the war (Sept. 1939 for we Brits) at a time when radar direction of large formations was in its infancy. In fact, no-one else was doing it - certainly not the Luftwaffe or the USAAF. As a result of misdirection and misidentification of aircraft formations by ground controllers, an intercepting flight was advised to be on the lookout for enemy aircraft. Having primed the interceptors to expect German aircraft, it was almost inevitable that someone would open fire. A number of men were court-martialled afterwards, and the senior ground controller was removed and re-posted.
As a direct result of the inquest into the events of that day, British ground control procedures were revised and became second to none by the time of the Battle of Britain. In fact, they became extremely effective, thanks to improved reporting, tracking and observation.
The Poles who fought in the RAF during the Battle of Britain (and after), fought bravely. but they were the direct beneficiaries of earlier refinements to the radar control system in Britain, without which they could not have done so well. So they owed a great deal to the Battle of Barking Creek, even if they didn't know it.
