German pilot forced to land. Who was he?

[gareth morris]

Hello all. 
I am currently reading a Royal Field Artillery memoir called the Unreturning Army. 
At one point the subject, Huntley Gordon, is with a battery of guns somewhere along the Menin Road. The observation post for the battery is very close by in the remains of the White Chateau( 100yds north of Menin Rd and apparently was Haig’s HQ 1st Ypres in 1915). 
It appears than on July 17th 1917 (give or take a day), Huntley Gordon witnessed a  “ black Striped” German aircraft being forced to land very close by, and the pilot taken a prisoner. 
The aircraft was supposedly undamaged. 
Huntly Gordon advises that the aircraft’s black strips signify a flight commander of Richthofen’s Scarlet Squadron. 

The air war is not my usual area of research and I have not been able to enlighten myself as to the circumstances/identity of pilot or aircraft etc. 

I would like to know more please if anyone can help. 
 

Many Thanks, Gareth.

Perhaps Ernst Clausnitzer of Jasta 4, shot down on 16 July 1917 during an attack on an observation balloon?

Jasta 4 had black and white stripes on their machines.

There's quite a bit of info about him and his downing online.

The book does refer to three aircraft attacking balloons. 
Two aircraft shot down and one forced to land. 
Sounds like Ernst is our man. 
I’ll have a google. 
Thanks for the info. 
cheers.
