 The leading infantry companies followed the barrage closely and attacked 'Hop Alley', 'Ale Alley' and 'Pint Trench', but Hop Alley proved stronger than expected and there was an additional hidden trench that had not been discovered or bombarded.The rest of the divisional attack was successful, and another attempt on the Hop Alley–Ale Alley complex was made two days later by a surprise attack without artillery preparation, which was also unsuccessful.After a short rest the 55th (WL) Lancashire Division was thrown in again at the Battle of Morval on 25 September.
