Daylight streamed through the mist. The guardians of the line with strained nerves and brain stood on the alert expecting grey Fritz momentarily to emerge from the mist with lowering brows and bayonet at the port. Our machine-guns chattered at the unknown, and meanwhile the enemy wire-cutters were at work clearing the way. It was not until half-past nine that the anonymous artillery gave way to the deadly personality of the foe. On the same lavish scale as that in which the guns were firing, stick-bombs showered into the front lines, exploding with their deafening and would-be-terrifying concussion of high explosive. The enemy soldiers got rid of all the bombs they had right away, and then very soon they were themselves to be seen. Tommy faced forward. But Fritz, though he came steadily across no-man's land offering an easy target, came also from the flanks and was soon to be seen in the rear. British troops were massed here and there and posted in clusters of defence, but the enemy with his vastly extended waves broke through at the thin places and the empty places. The alarm went to the flanks and the rear, but the runners found their various headquarters and destinations full of the men in grey. Surrenders were rapid on all hands. It was a puzzle what had happened. Brave units fought it out against fearful odds. Some reserve battalions led by their Colonels rushed in to counter-attack, and the Colonels fell and the battalions fell. Other reserve battalions received orders to retire and they retired. Others received no orders of any kind and remained where they were and were overtaken. All day of the 21st and all night long our lines were confusion worse confounded. On the 22nd there were Generals in the fray encouraging the defence in person and trying to re-establish lost contact right and left. But towards nightfall the last lines were over-run and the enemy was through.
