Hi Oleg,
As it seems you have a firm intrest in the history of JG 4, I can recommend you the 2 books about the history of JG 4 and the Sturmstaffel 1 written by Eric Mombeek:

But back to your request:

Gefr. Veit, (11./JG 4) POW sometime during march 45, Bf 1099G-14, ge.9)
Shot down near Kyffhäuser.
Oblt. Berg (II.(Sturm)/JG 4) killed in crash during landing sometime during march 45.
Flg. Bernhard Fichte (III./JG 4 - Staffel unknown) became a POW after combat in the area of Küstrin sometime during march 45.
