The mortars covered the withdrawal of 5 wounded men (Sergeant DEAZLEY, Sergeant MEARS, McCAFFERTY, and two gunners) and then were ordered to withdraw. Major GORDON-WATSON had come up to join them. THey came down the track towards No. 3 Company, but found it under heavy shell fire, turned and tried another way. As they came to the railway bridge they noticed, just in time, a wire stretched across the road to which was suspended a mine.
