According to the excellent book 'The Battle of France Then and Now', on the 5th June, only 1 Bf109E from JG51 is listed:

2/JG51.
Messerschmitt Bf109E. Shot down in combat with French fighters and crashed near Estrees-St-Denis, France, 1.45pm. Lt. Egon Falkensamer (F) captured. Aircraft a write-off.

From the Luftwaffe Loss Records, and mentioned in Jagdgeschwader 51'Molders' by Aders/Held, p54, there is the loss of a second Bf109E from JG51:

3/JG51.
Messerschmitt Bf109E. Shot down near Compiegne, France. Fw. Ernst Gräf (F) missing (or captured). Aircraft a write-off.

Can anyone confirm this second loss and fate of Fw. Gräf?
