Capt William Parker WRATHALL MC !/6 Bn. R. Highs. TF
For conspicuous gallantry and devotion to duty. This officer took over temporary command of the brigade at a time when it was much depleted after 48 hours fighting and consisted of small parties of various battalions, holding a line of over 5,000 yards, covering two battalions of another Division who were digging. For the best part of three days he was untiring in his efforts, collecting scattered parties and organising the hastily occupied and extended line. In particular when Brigade Headquarters had been rushed by the enemy and nearly surrounded, it as due to his energy that the personnel was extricated with little loss. His personal reconnaisances and unfailing resources in dealing with difficulties were the mainstay of the line.
