On the right of the London troops were some English county regiments of the 41st Division--the 60th Rifles (King's Royal Rifles), West Kents, and others--men who fought a great battle in the Somme fields that day when a Tank waddled up the high street of Flers with cheering men behind. On the night of June 6 they lay by St.-Eloi, in the salient opposite the Mound, a famous heap of earth taken over by the glorious old 3rd Division, and lost when the Canadians were violently attacked a year ago. This mound had been cratered by deep mines in those bad old days of fighting, but the enemy did not know that new shafts had been tunnelled under them, and that explosive forces enormously greater than in the first mines were about to be touched off. When the metal discs were fired by tunnelling officers the sound of thousands of our men cheering with the wild madness of enthusiasm could be heard even above the deafening uproar of the explosions. Then waves of riflemen ran forward, round the vast craters that had been flung open and across the first line of German trenches, frightfully upheaved and shattered. There were not many living Germans here, and they were dazed by the shock and terror of the mines and made no kind of fight. Beyond them was a strong place known as the Damstrasse, a street of concrete houses built of great blocks six feet thick, and so enormously solid that not even heavy shell-bursts could do much damage to them. This position had given great anxiety to our officers, who knew its strength, but as it happened, the violence of our shell-fire was so amazing that many of these blockhouses were blown in, and the garrison of Damstrasse was utterly cowed, so that they were captured by hundreds.
