I wonder if anyone can find any reason of starting in about May 1941 the great pruges agains higt staff of VVS RKKA.
Many high commanders of VVS were arested (some even after 22 VI 41), and they were executed in Otctober in Lubianka in
Moscow or in Barbysz near Kujbyszev. The last town was the place of killing by NKVD 18 top high VVS commanders (including Rychagov with his wife, Smushkievich, Stern, Loktionov, also could be Volodin).
