A Good Day For J30

I see from the "Today in History" section here at the
Aerodrome that (3) Jasta 30 aces (Bethge, Buddecke
and Marwitz) all scored victories today.

This is also not to say that maybe other J30 members
scored a victory or two. I am very interested to know
if any of the experts here can tell me anything about
the fighting of J30 on this date.

Where was their drome? (near Lillie?)
Who were their opponents?
Was this one large J30 flight with other jastas, or
smaller flights with each J30 ace involved?
What were the J30 casualties?

Anything at all--
Thank you,
J30
