Two days later, on relief by the Guards, the Division went out of the line, and after a few days in the district known as “A” area, with headquarters at Beauval, moved towards the scene of the battle in which it was to make its name. On the 22nd of August the 20th relieved the 24th Division in the sector north of the Guillemont-Montauban road. The 6th Divisional Artillery, which had been attached to the 20th Division since the 17th, when it had replaced that of the Guards, moved also to the new area. Divisional Headquarters was opened on the 23rd at Minden Post, near Carnoy. The 59th Brigade held with one battalion in the front line the right sector from the Guillemont-Montauban road just west of Guillemont village to the station, with Brigade Headquarters at the Briqueterie, about half a mile south-east of Montauban. The 61st Brigade had a battalion and a half in the front trenches, continuing the line to a point just south of the south-east corner of Delville Wood. Brigade Headquarters was north-east of Bernafay Wood. The 60th Brigade was in reserve at the Craters, close to the Carnoy-Montauban road, about 1000 yards from Carnoy. In order to appreciate the important part which the capture of Guillemont played in the general scheme, we will review briefly the course of the fighting up to this date. The original British line enclosed Maricourt on the east and north, running thence westward as far as Fricourt, which was in the hands of the enemy. It then turned rather west of north, past La Boisselle, Thiepval and Beaumont Hamel, all of which formed part of the German front line defences. Between the British right flank and the Somme the fighting was carried on by the French. The attack of the 1st of July gave us Montauban, Mametz, and a sharp salient each side of La Boisselle. These gains were increased in the fighting of the next fortnight to include Fricourt, Mametz Wood, Contalmaison, Ovillers-la-Boisselle and all ground between these places. On the left flank the German defences on the high ground south of Thiepval held out for many weeks. A second attack just before dawn on the 14th of July yielded very important results; a footing was gained on the great ridge which extends between Combles and Thiepval, and part of the enemy’s second defensive system was broken.
