At 5 o'clock on the morning of November 11, 1916, the special bombardment preliminary to the attack was commenced. It continued with bursts of great intensity until 5.45 o'clock on the morning of November 13, 1916, when it developed into a very effective barrage covering the assaulting infantry.
At that hour our troops advanced on the enemy's position through dense fog, and rapidly entered his first-line trenches on almost the whole front attacked, from east of Schwaben Redoubt to the north of Serre. South of the Ancre, where our assault was directed northward against the enemy's trenches on the northern slopes of the Thiepval Ridge, it met with a success altogether remarkable for rapidity of execution and lightness of cost. By 7.20 a.m. our objectives east of St. Pierre Divion had been captured, and the Germans in and about that hamlet were hemmed in between our troops and the river. Many of the enemy were driven into their dugouts and surrendered, and at 9 a.m. the number of prisoners was actually greater than the attacking force. St. Pierre Divion soon fell, and in this area nearly 1,400 prisoners were taken by a single division at the expense of less than 600 casualties. The rest of our forces operating south of the Ancre attained their objectives with equal completeness and success.
[Sidenote: Objectives reached on right bank of Ancre.]
North of the river the struggle was more severe, but very satisfactory results were achieved. Though parties of the enemy held out for some hours during the day in strong points at various places along his first line and in Beaumont Hamel, the main attack pushed on. The troops attacking close to the right bank of the Ancre reached their second objectives to the west and northwest of Beaucourt during the morning, and held on there for the remainder of the day and night, though practically isolated from the rest of our attacking troops. Their tenacity was of the utmost value, and contributed very largely to the success of the operations. At nightfall our troops were established on the western outskirts of Beaucourt, in touch with our forces south of the river, and held a line along the station road from the Ancre toward Beaumont Hamel, where we occupied the village. Further north the enemy's first-line system for a distance of about half a mile beyond Beaumont Hamel was also in our hands. Still further north--opposite Serre--the ground was so heavy that it became necessary to abandon the attack at an early stage, although, despite all difficulties, our troops had in places reached the enemy's trenches in the course of their assault.
