A shell hit the dressing station, bringing down the wall of the room in which the wounded were being dressed, and soon afterwards the enemy appeared on the ridge between Gouzeaucourt and Villers Guislain. The wounded were immediately placed in the Decauville train and got away and the A.D.S. was abandoned just before the enemy surrounded the village. Lieut.-Colonel Osburn, commanding the 60th Field Ambulance, went back to his rear headquarters at Fins and ordered all available bearers to march towards Gouzeaucourt. Captain R. V. C. Ash had meanwhile withdrawn the unit. A provisional A.D.S. was formed half way between Fins and Gouzeaucourt, and there three or four hundred wounded were dressed. In the evening, when Gouzeaucourt had been retaken, most of the stores were rescued from the original dressing station. When the enemy’s attack was launched on the morning of the 30th, Brig.-General Hyslop was at rear Divisional Headquarters at Sorel on his way home on sick leave, and he took command of the headquarter details of the 20th and 29th Divisions, and also of the details of the 20th Division at Nurlu. Part of this force was rushed forward towards Gouzeaucourt and part took up a position near Revelon and helped to repel an attack. All transport except the mobile ammunition echelon was sent back to Moislains. A line of straggler posts was formed, and all labour units in the neighbourhood, as fast as they could be collected, were employed either in digging or in carrying forward ammunition and R.E. material. Towards evening it was ascertained that the situation was in hand. Thanks to an alternative emergency ground line which the 20th Divisional Signal Company had laid to Corps through the outskirts of Gouzeaucourt, to supplement the poled cable route erected by Corps, signal communication between Divisional Headquarters and Corps was successfully maintained throughout the day, in spite of the fact that at one time a portion of the line passed into German hands and out again. This line also proved of inestimable value to the 6th, 12th and 29th Divisions, whose communications with Corps had broken. Constant and most strenuous efforts were made to maintain signal communication forward of Division. Cpl. Thompson gained the M.M. for conspicuous bravery in mending lines time after time under heavy shell-fire.
