The entire front on which the British attacked was over 8,000 yards. On the right, or east, the advance began from the western end of Regina Trench from the British position about 700 yards to the north of Stuff Redoubt. From this point a German trench known as the Hansa line ran northwestward to the Ancre, directly opposite the village of Beaucourt. On the extreme right, north of Stuff Redoubt, to reach that trench meant an advance of only a score or so of yards. To the westward, above Schwaben Redoubt half a mile, the advance was nearly 1,000 yards. By St. Pierre Divion, along the valley of the Ancre itself, the advance was over 1,500 yards. Everywhere in this sector the British troops were successful. They gained in this offensive a stretch of 3,000 yards north of the Ancre to an average depth of about a mile. The victory of the British troops was especially notable, because they had struck frontally at the main German first line with tier upon tier of trenches which the Germans had strongly fortified and wired for two years past. One English county battalion alone to the south of Beaumont-Hamel took 300 prisoners, and in the village itself 700 were captured, mostly soldiers from Silesia and East Prussia. At the close of the day over 2,000 German prisoners had been taken, and the ground won by the British amounted to about four square miles. During the night of November 12, 1916, and during the day following in the clean-up of the labyrinthian defenses which the Germans had skillfully constructed 2,000 more prisoners were added to the number already captured in this sector. The British advance had brought them to the outskirts of Beaucourt-sur-Ancre, which was taken on November 14, 1916. Pushing on through the village to the left of it, the British troops advanced over the high ground to the northeast of Beaumont-Hamel, on to the road from Serre to Beaucourt, having gathered in another thousand prisoners on the way.
