But the newcomers had gone one better than bullets for fiendish destruction. As the first one approached a black blob fell away from it, and next second there was a rending crash, a leaping cloud of smoke and dust whirling and eddying up from the road. The machine roared over and past, with her machine-gun hailing bullets down the road, and far down the road came another billowing cloud of smoke and the crash of another bomb. The third machine followed close, also machine-gunning hard and also splashing bombs down at intervals, one falling with horrible effect fairly in a little crowd of women and children clustered under and behind a country cart. The cart was wrecked, and the horse and half of the women and children.... The two observers gave what help they could, their faces white and their hands shaking and their ears tingling as they worked. The whole scene after the passing of the destroyers was heart-rending and pitiful and far too horrible for description. And the cruel part of it was that it was all such useless destruction, such wanton savagery, such a brutal and wilful slaughter of the innocents. The low-fliers were too close down for there to be any possibility of their not knowing well what they were shooting and bombing. There was not a sign of a uniform on the road; it was packed with what clearly and unmistakably was a crowd of refugees, of helpless women and children. It was hard to imagine what the Huns hoped to gain, what object they could have had in such indiscriminate murder; but, object or no object, its happening is a matter of cold history. It was growing late when the two observers, continuing their journey, saw a distant aerodrome, made their way across the fields to it, explained themselves, and were offered dinner first, and then transport back to their unit. The two told their tale of the day while they waited with the Squadron for dinner to be served. It was dark by this time, and an annoying delay came before dinner in the shape of an order to put all lights out, and in the droning approach of some enemy bombers. They passed somewhere overhead, and the machine-gun defences fired a few streams of ineffectual bullets up at them. One bomb whistled and shrieked down and burst noisily a few hundred yards from the 'drome and others farther afield. The pilots and the two observers were collected again just outside the door of the mess listening to the distant drone of the Hun bombers, watching the flicker and jump of gun flashes in the horizon and a red glare that rose in a wide steady glow from one or two points. It was an unpleasant reminder of the trying time the Army was having, of the retreat they had made, of the stores and dumps that had been fired to prevent the enemy taking possession of them.
