"But our artillery was not idle. The field guns, pushed well forward, showered shrapnel upon the British position, the howitzer shells hurtled over our heads on their way to the enemy in constantly increasing numbers as the ranges were verified by the trial shots, while a terrible and unceasing reverberation from the north-east told of the supporting attack made by the IXth and Xth Corps upon the blackened woods held by the English. The concussion of the terrific cannonade that now resounded from every quarter was deafening; the air seemed to pulse within one's ears, and it was difficult to hear one's nearest neighbour speak. Down in the valley our men appeared to be suffering severely. Every forward move of the attacking lines left a perfect litter of prostrate forms behind it, and for some time I felt very doubtful in my own mind if the attack would succeed. Glancing to the right, however, I was encouraged to see the progress that had been made by the troops detailed for the assault on Copped Hall and Obelisk Fort, and seeing this, it occurred to me that it was not intended to push the central attack on Epping home before its flank had been secured from molestation from this direction. Copped Hall itself stood out on a bare down almost like some mediæval castle, backed by the dark masses of forest, while to the west of it the slopes of Fort Obelisk could barely be distinguished, so flat were they and so well screened by greenery. "But its position was clearly defined by the clouds of dust, smoke, and débris constantly thrown up by our heavy high-explosive shells, while ever and anon there came a dazzling flash from it, followed by a detonation that made itself heard even above the rolling of the cannonade, as one of its big 7·5 guns was discharged. The roar of their huge projectiles, too, as they tore through the air, was easily distinguishable. None of our epaulments were proof against them, and they did our heavy batteries a great deal of damage before they could be silenced. "To cut a long story short, we captured Epping after a tough fight, and by noon were in possession of everything north of the Forest, including the war-scarred ruins that now represented the mansion of Copped Hall, and from which our pom-poms and machine guns were firing into Fort Obelisk. But our losses had been awful. As for the enemy, they could hardly have suffered less severely, for though partially protected by their entrenchments, our artillery fire must have been utterly annihilating."
