In another part of the field the Royal Irish Lancers captured a supply train, which was escorted by cavalry outnumbering them by five to one. The Irishmen managed to get into ambush along the road by which the convoy must pass. As it came up they opened fire. The Germans believed themselves to be attacked by an army, and fell into hopeless confusion. Then the lancers mounted, and crashed into the disordered throng of men, horses, and wagons. The supply column was captured, and the remnants of its escort surrendered.
Meanwhile the British right was rapidly moving towards the river some ten miles to the east, and the 5th French Army was fighting a fierce frontal battle higher up the stream. Taken in flank and in front, von Kluck could no longer hold the line of the river. On the 7th the Allied advance was continued, and on the 8th the Germans strove hard to make a stand against the British on the high ground to the north of the Grand Morin. Heavy guns had been posted on this high ground, and during the morning an artillery duel raged between the German rearguard and the advancing British. A stubborn resistance was made, but the Germans were dislodged, though not without considerable loss.
About midday the last of our infantry were across the Grand Morin, and were pushing on rapidly through a beautiful country of orchards and cornfields towards the Petit Morin. Late in the afternoon the enemy made another and even more desperate stand. Savage attacks were made on Haig's 1st Corps, which suffered severely. Again and again the Germans bore down on the British in close-packed ranks; but though they flung away life like water, they could make no headway. British rifle fire and British bayonets were too much for them. Before sunset the British had a firm hold of the north bank of the river.
On the 9th they crossed the Marne below Meaux,[103] and took in flank the German forces which were defending the line of the Ourcq. You know that the 6th French Army had been for the last few days attacking these forces in front. On the 8th von Kluck had hastily reinforced his army on the Ourcq by two corps drawn from the south. These corps made attacks of such violence that the French had hard work to resist them. Nevertheless they held their ground well, and in one action took three of the enemy's standards. They were now reinforced, and on the 10th they advanced with great spirit, while the British, now across the Marne, attacked the German left flank. Fearful of being enveloped, the Germans retreated from the line of the Ourcq, and immediately the British army went in pursuit. For the first time the Germans were on the run.
