So the great drive continued, and every hour of the day furious rearguard actions were fought. The Germans had taken to heart the lesson of the Allies' retreat, and on every possible occasion their rearguards stood and fought in order to delay the pursuit. They lost heavily in killed, wounded, guns, and prisoners; but they were prepared to pay this price rather than suffer their main bodies to be overwhelmed. The line of German retreat was strewn with the wreckage of men, horses, weapons, and equipment. A British artillery officer gives us a good idea of what this rearguard fighting was like. He is describing the crossing of a little river. "The Germans were holding the opposite bank, a very steep bluff, with a battalion of riflemen and eight machine guns. These guns were trained on the road where it was fully exposed for about one hundred yards, and nothing could cross. One section of my battery was trying to locate them and knock them out. So I took my section up a hill behind these, and waited for any targets to appear. Our advance guard had been working well. By taking cover in the woods they had managed to get down into the river-bed and round the flanks. From there they opened a hot fire on the German machine guns. From my position I could see a portion of the road on the opposite bank. I had just got the range for this when a German machine gun came galloping up. I fired two rounds at it. The first was over and just behind; the second short. However, I had never seen anything move quicker than that gun. By now our infantry had forced the German riflemen back, and we had orders for a general advance. As we crossed the bridge I heard that seven of their machine guns had been captured. We wound up and up, and on all sides saw evidence of our fire. In one place an ammunition wagon had been hit. Both horses were blown over into the ditch. A bit higher up was a young boy, hit in the back. All that we could do was to give him water. He told me that his orders had been to stay till shot or captured. These German infantry are a brave lot." Now we must hark back and see how the French armies to the right of the British were faring. The 5th French Army, which was next to the British on their right, had a threefold part to play. It had to support the British on its left and the 9th French Army on its right. Further, it had to throw back the Germans facing it. On the 7th it made a leap forward, and during the following days, after desperate fighting, reached and crossed the Marne. In its advance it captured many guns, howitzers, machine guns, and more than a million cartridges.
