Michael MacDonagh,
The Irish on the Somme
“ In preparation for the advance, a thunderstorm of British fire and steel broke over the German trenches. The splitting, tearing crashes of the mighty "heavies" lying miles back; their firing accuracy, the penetrating power of their shells, had a heartening influence on the men. "Ah, those guns," said an officer of the Royal Irish Regiment—"their effect, spiritual and temporal, is wonderful. Your own makes you defiant of the very devil; the enemy's put the fear of God into you." The German lines were blotted out by smoke and flying soil. The ground rocked and swayed. ”
