The German infantry rifle fire, breaking from the shelter of the woods to encounter a stronger British fire than was anticipated, was at first ineffective. As to the mass formation they depended upon overwhelming reserves to take the places of those dead piled in heaps before the British trenches. It was General Grant's "food for powder" plan of attack repeated.
Thus the battle raged upon the entire length of the British line, with repeated advances and retreats on the part of the Germans. Now and then the bodies almost reached the British trenches, and a breach seemed in certain prospect. But the British sprang upon the invaders, bayonet in hand, and drove them back to the shelter of the woods. The Irish regiments, especially, were considered invincible in this "cold steel" method of attack, their national impulsive ardor carrying them in a fury through the ranks of an enemy. But at Mons always the Germans returned in ever greater numbers. The artillery increased the terrible rain of shells. Pen pictures by British soldiers vividly describe the battle somewhat conflictingly.
"They were in solid square blocks, standing out sharply against the skyline, and you couldn't help hitting them. It was like butting your head against a stone wall.... They crept nearer and nearer, and then our officers gave the word. A sheet of flame flickered along the line of trenches and a stream of bullets tore through the advancing mass of Germans. They seemed to stagger like a drunken man hit between the eyes, after which they made a run for us.... Halfway across the open another volley tore through their ranks, and by this time our artillery began dropping shells around them. Then an officer gave an order and they broke into open formation, rushing like mad toward the trenches on our left. Some of our men continued the volley firing, but a few of our crack shots were told off for independent firing.... They fell back in confusion, and then lay down wherever cover was available. We gave them no rest, and soon they were on the move again in flight.... This sort of thing went on through the whole day."
From another view we gather that "We were in the trenches waiting for them, but we didn't expect anything like the smashing blow that struck us. All at once, so it seemed, the sky began to rain down bullets and shells. At first they went wide ... but after a time ... they got our range and then they fairly mopped us up.... I saw many a good comrade go out."
