In 'The Big Show' Pierre Clostermann included a characteristically vivid story of leading a patrol to Remagen and engaging with Ar 234s, Me 262s and long-nose Focke-Wulfs but doesn't give a date.
There is even a 'carefully researched'
Nicholas Trudgian painting including a Tempest with JJ squadron letters yet nothing appears to be said about this mission in the March 1945 ORBs of either 274 or 56 Squadrons (both of which Clostermann served with in March), nor in Shores & Thomas's '2nd Tactical Air Force, Volume Three' (Classic, 2006). Nor does any of the German daily sitreps mention Tempests being encountered at Remagen.
So … am I safe in concluding that Clostermann was indulging in dramatic licence or is there some basis for the RAF (with or without Clostermann) intervening over Remagen at any point?
