V Inglefield, The History of the Twentieth (Light… (1922)
“ The enemy’s line ran a little to the west and north-west of Guillemont, which being part of his original second line of defence, though by this time reduced to a mass of ruins, was very strongly fortified. The village lay on high ground, but in a slight depression which is really the head of a long valley running up from the west. To the north, high ground extends for 3000 yards, with the village of Ginchy at the highest point; [71] to the south, after forming a ridge from 400 to 1000 yards across, the ground fulls sharply in a series of irregular spurs and re-entrants towards the Somme. ”
