Hazebrouck battles in 1918 - Devons

[mcderms]

Looking for help researching the 1st battalion Devonshire Regt and their involvement in the battles around Hazebrouck, Morbeque and Thiennes in April 1918. My great uncle was KIA when the HQ was shelled on 18/4/18 and I'm trying to piece together his last days as much as possible.

 

I have the war diaries but there doesn't seem to be much else around. I'm particularly trying to locate the battn and 2nd / 3rd company HQ locations as that's where he was KIA.

 

Any help much appreciated!
