Now we must leave these gallant men for a moment and see what was happening to the Allies on either flank. To the right of the 1st Division the Moroccans, who had already taught the Germans to fear them, were holding their trenches valiantly. To the left of the 1st Division was the 2nd Division, advancing towards Braye, which you will see on the extreme right of the picture-diagram (page 249). Its right wing had been checked by German artillery and rifle fire, and was now held up. Between the firing lines of the 1st and 2nd Divisions there was a stretch of ground left open, and Sir Douglas Haig saw at once that the enemy would probably try to thrust in a wedge at this point. He therefore hurried the 3rd Infantry Brigade into the gap, but only just in time. Almost immediately it was fiercely shelled, and a strong force of Germans was seen advancing. Two battalions of the 3rd Brigade at once dashed towards them; a battery of field guns galloped up, and opened fire at short range, and the enemy hastily withdrew. Later in the day the enemy actually gained a footing between the First and Second Corps, and threatened to cut the communications of the latter. Sir Douglas Haig at this time was very hard pressed, and he had no reserves. The only reinforcements which Sir John French possessed consisted of three brigades of Allenby's cavalry. They now galloped up, dismounted, and took their places in the firing line. By their timely help the enemy was driven back, and the danger was averted. Desperate fighting continued the whole of the morning and far into the afternoon. Attack and counter-attack continued almost without a pause. The Germans rolled forward in waves, only to be beaten back; the British advanced in their turn, only to suffer a like fate. In each case it was as though lines of breakers were dashing against the cliffs of a rocky seashore. Big guns thundered; Maxims and rifles cracked unceasingly. Huge siege guns, with a range of 10,000 yards, also hurled their enormous shells upon the British. These were the guns which had battered down the forts of Maubeuge a few days before.
