Luftwaffe losses on 05.05, 26.06, 17.08 and 20.08.1944

[Maxim1]

Hello, gentlemen.

Has anyone any info on possible Luftwaffe losses on the following dates:

5 May 1944 - Fw 190 - Shestaya Versta (area of Sevastopol and the Cape of Chersones, Crimea)
26 June 1944 - Fw 190 - Ridomlya (area of Tolochin, between Orsha and Borisov, Belarus)
17 August 1944 - Fw 190 - airfield of Nemokshty (or Nemakščiai, Lithuania)
20 August 1944 - Bf 109 - south of Smilcha (cannot find the exact location, but again in Lithuania, area of Kovno/Kaunas may be)

I'm trying to verify the claims made by ml.l-t Semyon Belkin (one of the aces of 812 IAP) and will very much appreciate any help.

Best regards,
Maksim
