Throughout the 11th and 12th heavy fighting continued in which the 167th Brigade co-operated with the Guards on the left in numerous efforts to clear out the re-entrant and reach the Ginchy Quadrilateral. This magnificently defended position, however, held out against the most gallant attempts of the attackers. During the night of the 11/12th September the 167th Brigade was also relieved, the line being taken over by the 16th Brigade of the 6th Division. The Battalion remained at Billon Farm for three most welcome days of rest and reorganisation during which the weather, which now once more became fine and warm, was of inestimable value in cheering the troops after their somewhat trying experience. The relief to the men's spirits on emerging even for a short spell from the ghastly featureless waste of the battle area to surroundings where trees still bore their leaves, roads still crossed the hillsides, and houses were not completely effaced, was immense; and by the time the period of rest was over the Battalion was once more braced up to continue the struggle. One or two changes occurred during this period among the officers of the Battalion, of which the most important was the assumption of the Adjutancy by Lieut. W. J. Boutall on the evacuation to hospital of Capt. R. L. Herring, who had occupied this trying position practically since the Battalion joined the 56th Division. 2/Lieut. Garratt assumed the duties of Assistant Adjutant almost immediately afterwards. Capt. J. T. Sykes left the Battalion for attachment to the Indian Army, and the signalling officer, Lieut. E. W. Monk, to join the R.A.F. The latter's duties were taken over by 2/Lieut. S. J. Barkworth, M.M. In addition to these 2/Lieut. A. C. Knight was evacuated to hospital. _The Battle of Flers-Courcelette 15th-18th September_ The renewal of the offensive was not long to be delayed. The object of the High Command was to follow up the blows delivered against the German positions as rapidly as possible, and to leave the enemy little respite for reorganisation and rest. The constant hammering on his defences had already had an appreciable effect on his morale, and it was hoped that before long the strain on his resources would prove so great that the situation would develop rapidly in favour of the Allies.
