In order to complete this description of these widespread operations, which are difficult to {232} synchronise and bring into any settled plan, one must return to what was going on upon the left of Delville Wood. Towards the end of August the Thirty-third Division, which had covered the line between Delville and High Woods, was relieved by the Twenty-fourth. Upon the left of the Twenty-fourth the First Division was still continuing that series of operations upon High Wood which have been already described. On their left in turn was the Fifteenth Scottish Division, the left unit of Rawlinson's Army. They were busy from this time onwards in digging their assembly trenches for the great assault. The first incident which calls for attention was a very sudden and violent German attack upon August 31 upon the Twenty-fourth Division. The German onslaught met with some success at first, as it burst through the line of the 13th Middlesex, a battalion which had lost heavily in the attack upon Guillemont ten days before, and was for the moment more fit for a rest-camp than the forefront of the battle. The 9th Sussex, who were on the right of the Middlesex, stood firm, and the German advance, which had penetrated some distance down the long communication trench which is known as Plum Street, was eventually brought to a halt. This result was partly brought about by the initiative and determination of a 2nd Lieutenant of the Middlesex, "a little pale-faced fellow," who carried off a Lewis gun, and worked it from different positions down the trench, continually holding up the Germans and giving time for the Sussex men to gather such a force at the end of Plum Street as prevented the Germans from debouching into the larger trenches which led down towards Longueval. The attack had been equally {233} severe upon the 72nd Brigade, who held the right of the division, which included the northern end of Delville Wood. They entirely repulsed the Germans with great loss, the 8th Queen's Surrey being the battalion which bore the brunt of the fight. On the next day, September 1, the 17th Brigade came up to restore the situation on the left, and by evening the position had been almost cleared. On the 2nd, 3rd, and 4th there were fresh German attacks, but the line was now firmly held and no impression was made. None the less, the fighting had been costly, and the depleted division had 2000 more names upon its roll of honour. It was drawn out shortly afterwards, but its artillery, which was left in the line, had the misfortune to lose its distinguished chief, General Phillpotts, upon September 8. We shall now move a mile eastwards to follow the First Division in its difficult and, as it proved, impossible task of improving our position as regards High Wood, a spot which caused us more delay and loss than any other upon the German line.
