Amiens seemed threatened on the morning when, to the north, Albert was held by a mixed crowd of Scottish and English troops, too thin, as I could see when I passed through them, to fight any big action, with an enemy advancing rapidly from Courcellette and outflanking our line by Montauban and Fricourt. I saw our men marching hastily in retreat to escape that tightening net, and while the southern side of Amiens was held by a crowd of stragglers with cyclist battalions, clerks from headquarters staffs, and dismounted cavalry, commanded by Brigadier-General Carey, sent down hurriedly to link them together and stop a widening gap until the French could get to our relief on the right and until the Australians had come down from Flanders. There was nothing on that day to prevent the Germans breaking through to Amiens except the courage of exhausted boys thinly strung out, and the lagging footsteps of the Germans themselves, who had suffered heavy losses all the way and were spent for a while by their progress over the wild ground of the old fighting-fields.
