At the risk of carrying the account of the {212} operations near High Wood and between High Wood and the west edge of Delville Wood to a point which will compel a considerable return in order to bring up the narrative of the rest of the line, we shall still continue them to the date of the great advance of September 15, when the whole vast array from Pozières upon the left to Leuze Wood upon the right heaved itself forward, and local attacks gave place to a big concerted movement. We shall therefore continue to follow the fortunes of the First Division in their hard task in front of the Intermediate Trench. After the failure of their attempt to get forward upon August 19 the action died down, and for four days there was no fresh advance. The 3rd Brigade had come up into the front line, and upon August 24 the Munsters made an attempt upon the German trench without success. Colonel Lyon lost his life in this affair. Upon August 25 another battalion of the Brigade, the South Wales Borderers, made a bombing attack, and again were in the trench and once again were driven out. They were not to be denied, however, and upon August 26 actually occupied 180 yards of it, taking one of the deadly guns which had wrought such damage. On the 27th a German counter-attack was heavily repulsed, but an attempt of the South Wales Borderers to improve their success was also a failure. On the evening of this day the Fifteenth Scottish Division took over the position in front of the Intermediate Trench, the First Division moving to the right and enabling the Thirty-third Division upon its flank to move also to the right. The Fifteenth Division was able in very tempestuous weather partly to outflank the Intermediate Trench, with the result that upon the afternoon of August 30 {213} the remains of the garrison, finding that they were in a trap, surrendered. Two machine-guns with 140 men were taken.
