Obstlt Ewald Janssen - Kommodore SG 4

[Adriano Baumgartner]

Could someone give me more information about this officer´s activities?
Apparently he flew Ju 87 A with the Condor Legion ( did he fly with them ? ). Later he flew with StG.163 and StG.2.
From mid 1943 up to October, he was Gruppenkommandeur I/JG 300, where he claimed a 4-engined RAF bomber on 23/24 September 1943. ( Could someone inform me the codes of his machine, werknummer or add any more claim while with JG 300 )?
He was then posted to JG 302 ( Any claim with this unit ? )
Finally he assumed, as Kommodore, the SG 4. On 24 October 1944 he claimed a Il-2 with this unit ( his final victory as far as I know ).
He flew more than 300 missions and was awarded the RK later on October 1944. Why he lately was dismissed from SG 4? Where he went then?
Any details of his claims, or successes as a Stuka or SG pilot? Was he injured on operations while with SG 4?

Glad in advance….he apparently came to Brazil and died here. Major Martin Drewes told he met Janssen here, but lost contact.

Thank you in advance for any news on this officer´s career.
