The disposition of the Brigade was now as follows. On the right, at the quarry on the east of Heudicourt (the old Brigade Headquarters), was “B” Company of the 2nd, under Captain Green, with one company of the 11th Royal Scots and a few details of the 21st Division extending the line on the right. In the centre was the 4th Regiment, and on the left the 1st Regiment, both in the Brown Line. But the situation was full of peril, for the Brown Line was hopelessly outflanked on the right, and the enemy was moving northwards round the south end of Heudicourt. Communication with headquarters had become impossible, and a heavy responsibility fell upon the junior commanders, who flung out defensive flanks and fought rearguard actions with the coolness of veterans. While the guns were falling back, about thirty enemy airplanes, flying low, kept up a continual fire on the teams and also on the infantry in the trenches. Everything depended on whether the German advance could be stayed till darkness came, and under its cover the various units could reach the Green Line. The Brigade Headquarters were at Sorel, and in the dusk the Germans could be seen in great strength moving westward south of the village. As our wounded and guns were passing through the place it was vital to defend it until the retirement was complete. The whole countryside seemed to be in flames; Heudicourt was spouting like a volcano, and everywhere was the glare of burning stores and bursting shells. Dawson formed up his Brigade Headquarters Staff, and put them into the trenches east of Sorel, to give the guns and wounded time to get clear. About this time Major Cochran, the brigade major, returned from leave and resumed his duties—duties which, for the two days left to him on earth, he was to perform with a noble fidelity. The Headquarters details succeeded in arresting the enemy’s advance, and, before he had time to reconnoitre or to organize an attack, the last guns had passed through Sorel, Brigade Headquarters withdrawing to Moislains. It was here that Lieutenant M. Webb was killed. Only darkness could save the Brigade, and the darkness was fast falling.
