On the night of September 1, the First and Second Army Corps were in touch once more at Betz, and were on the move again by 2 A.M. upon the 2nd. On this morning the German advance was curiously interlocked with the British rear, and four German guns were picked up by the cavalry near Ermenonville. They are supposed to have been the remaining guns of the force which attacked Battery L at Nery. The movements of the troops during the day were much impeded by the French refugees, who thronged every road in their flight before the German terror. In spite of these obstructions, the rearward services {134} of the Army--supply columns, ammunition columns, and medical transport--were well conducted, and the admiration of all independent observers. The work of all these departments had been greatly complicated by the fact that, as the Channel ports were now practically undefended and German troops, making towards the coast, had cut the main Calais-Boulogne line at Amiens, the base had been moved farther south from Havre to St. Nazaire, which meant shifting seventy thousand tons of stores and changing all arrangements. In spite of this the supplies were admirable. It may safely be said that if there is one officer more than another for whom the whole British Army felt a glow of gratitude, it was for Sir William Robertson, the Chief of the Commissariat, who saw that the fighting man was never without his rations. Greatly also did they appreciate the work of his subordinates, who, wet or fine, through rainfall or shell-fall, passed the food forward to the weary men at the front.
