During the two days' fighting in this region no British troops won greater distinction than the Scots and the Royal Naval Division. In all the German lines in France there was no more formidable position than the angle immediately above the Ancre, where Beaumont-Hamel lay in a hollow of the hill. On the morning of November 13, 1916, the Royal Naval Division attacked the stretch from just below the "Y" ravine on the south of Beaumont-Hamel to the north side of the Ancre. After a preliminary bombardment, which played havoc with the German barbed-wire entanglements protecting their front line, the British naval troops swept over the line with a rush as if the barriers had been made of straw. The British right rested on the Ancre as they swept across the valley bottom. Northwest, where there was a rise of ground, the center of the line had to attack diagonally along the slope of the hill. At the top of the slope there was a German redoubt hidden in a curve, and invisible in front, composed of a triangle of three deep pits with concrete emplacements for machine guns which could sweep the slope in all directions. This formidable redoubt was situated immediately behind the German front trench, reaching back to, and resting on, the second. At all points the British naval troops carried the front trench by storm. On the right they rushed along the valley bottom and the lower part of the slope, carrying line after line of trench on to the dip where a sunken road ran along their front going up from the Ancre to Beaumont-Hamel on the left. Here for a short space of time the British troops rested while others, also of the Naval Division, came up and swept through them on and up the slope until they had won a line beyond. After this the first line caught up with them again, and they all swept on together in a splendid charge that covered a good 1,500 yards and which brought them to the very edge of Beaucourt. It was during this operation that a British battalion commander was wounded, but continued to lead and animate his men during the entire advance. Meanwhile the British right center was held up by the redoubt. The German machine guns, while checking the troops in front of them, also swept the ground along the face of the slope to the left. Here the troops of the Royal Naval Division suffered badly, but they continued to advance under the withering fire, winning the first and second line trenches, and then, as supports came up on the right, braving the machine-gun fire, they pushed on across the dip and sunken road up the slope toward Beaucourt. Here all the troops made a junction, forming a line on the Beaucourt-Beaumont-Hamel road. Back of this line the Germans still held the central parts of the trenches, over the two ends of which the British troops had swept. The redoubt still remained intact and other important positions were in German hands.
