At Etreux, where with the rest of the Brigade the Battalion entrenched itself after the shallow pattern of the time, it had its first sight of a German aeroplane which flew over its trenches and dropped a bomb that “missed a trench by twenty yards.” The Battalion fired at it, and it “flew away like a wounded bird and eventually came down and was captured by another division.” Both sides were equally inexperienced in those days in the details of air war. All that day they heard the sound of what they judged was “a battle in the direction of Le Cateau.” This was the Second Army Corps and a single Division of the Third Corps under Smith-Dorrien interrupting our retirement to make a stand against four or more German Army Corps and six hundred guns. The result of that action caused the discerning General von Kluck to telegraph that he held the Expeditionary Force “surrounded by a ring of steel,” and Berlin behung itself with flags. This also the Battalion did not know. They were more interested in the fact that they had lost touch with the Second Division; and that their Commanding Officer had told the officers that, so far as he could make out, they were surrounded and had better dig in deeper and wait on. As no one knew particularly where they might be in all France, and as the night of the 26th was very wet, the tired men slept undisturbedly over the proposition, to resume their retreat next day (August 27) down the valley of the Sambre, through Vénérolles, Tupigny, Vadencourt, Noyales, to the open glaring country round Mont d’Origny where the broad road to St. Quentin crosses the river. It was in reserve that day, and the next (August 28) was advance-guard to the Brigade as the retirement continued through Châtillon, Berthenicourt, and Moy to Vendeuil and the cross-roads west of the Vendeuil-La Fère road while the Brigade marched on to Bertaucourt. After the Brigade had passed, the Battalion acted as rear-guard into Bertaucourt. Here No. 2 Company, under Major Stepney, was sent to Beautor to assist a section of the Royal Engineers in demolishing a bridge across the river there--an operation performed without incident--and in due course joined up with the Battalion again. By this time, the retreat, as one who took part in it says, had become “curiously normal”--the effect, doubtless, of that continued over-exertion which reduces men to the state of sleep-walkers. There was a ten minutes’ halt every hour, on which the whole Battalion dropped where it stood and slept. At night, some of them began to see lights, like those of comfortable billets by the roadside which, for some curious reason or other, could never be reached. Others found themselves asleep, on their feet, and even when they lay down to snatch sleep, the march moved on, and wearied them in their dreams. Owing to the heat and the dust, many suffered from sore feet and exhaustion, and, since ambulance accommodation was limited, they had to be left behind to follow on if, and as best,
