Willy Rosenstein was a member of Jasta 27 and
Hermann Goering was the Sqn.Leader. It has been said that he flew wingman for Goering (he was an excellant pilot, having obtained his flying license in 1911 at the age of 19). Willy states in his autobiography that H.G. made an anti-semetic remark and refused to withdraw it in front of his comrades. He applied for a transfer. However, in his assessment which H.G. had to write, he states that Willy had won his confidence for his air combat skills "and the affection of his Staffel-mates because of his fine comradship".
H.G. goes on to say that Willy was showing signs of nervous exhaustion as a consequence of nearly six years continuous activity as a pilot and recommended that he be transfered to a KEST in order to recover his strength. This was an assignment for battle-weary aviators to regain their strength.
When he had recovered his strength, Willy applied to be transfered to Jasta 40, where
Helmut Dilthey was commander and had been with Willy in jasta 27.
Unfortunately, on his first flight Dilthey was killed by his own anti-aircraft fire and
Carl Degelow was appointed in his place. Degelow became so impressed with Willy's ability that he appointed him his deputy and he took over when Degelow went on leave.
Degelow did not, however, have anything to do with Goering 'assisting' Rosenstein to leave Germany. It was another comrade from Jasta 27 who asked Goering to remove obsticles that made it difficult to leave Germany.
Hope this clears up the matter for you. Lawrence Milner
