Today we go into a Rest Camp some miles from here. It will be a pleasant change, although I should like a few more nights here as I have a job to finish. Last night I and a Sergeant (an exMetropolitan Police Force man) went out to the German lines. We crawled out slowly, listening, and got right up to the German parapet and reconnoitred their wire. Apparently they are starting a most elaborate system of wire defence. The part we were opposite was completed and I was dying to go tonight and find out details and especially how far the new system went and if they were working on it now.
