Hey Adriano,

First no mention of time in the loss list in Prien’s book.
The Gruppe flew multiple mission that day: jabojagd & Platzchutz in the area of Rheine / Osnabrück and scores 3 victories:
1. Uffz. Hans Stenglein (5.) a Spitfire at 7:50, 5 km südwestl. Metelen
2. Gefr. Helmut Laub (6.) a Spitfire at 11:23, südl. Hesepe
3. Uffz. Helmut Händel (7.) a Spitfire at 11:45, nordöstl. Osnabrück.

As Uffz. Vieltsch was lost near Osnabrück and his staffel comrade shot down a Spitfire in that area, I would guess he wast lost between 11:00 & 11:45/12:00 hrs?
6.staffel lost also Lt. Wilhelm Hahn in a Bf 109G-14/AS, ge.5; shot down by a fighter and crashed north of Ahaus (WIA);
7.staffel lost 3 pilots one wia and 2 Kia
5.staffel lost 1 pilot wia.
But as no times were mentioned its hard to tell who was lost in which mission.
Hope this helps a little bit.
Kind regards,

Dirk
