Hi,
Rick's right, Peselhoek it is now, part of Poperinge. I had been thinking of Poperinge already, but didn't make the link with Peselhoek...
Duckman and Graeme however did make the link !
Many troops were lying in reserve in this area, Poperinge also well known for Talbot House.
Also there was a station overthere at the time ! There was a campement in the Peselhoek area, known as P camp.
Go to :

Then you go to the left down corner, where you will see a symbol in the form of Belgium, it's the one on the right down, click it, you get a map of Belgium, and under the map click on Stadsplan Groot Poperinge
You will get a map of Poperinge - go to square D5 click on it, you will see the Pezelstraat and the Pezelhoekstraat. The corner of both these streets is the real Pezelhoek.
Best from Johan
