"... The 15th Infantry Brigade took over the left half of the Divisional front, north of the junction of Snap Trench and Soot Avenue. Brigadier-General Oldman decided to attack with two battalions, the 1st Bedfords on the right and the 1st Cheshires on the left, the latter keeping one Company specially detailed to deal with Beaucamp. The 16th R. Warwicks were in support,  with orders to pass through the 1st Bedfords when the latter had captured Dunraven Trench, while the 1st Norfolks were to be held in Brigade Reserve..."
