As scouts of the gunners, as their watchers and signallers, were the boys of the Royal Flying Corps. I said yesterday that they were uplifted with a kind of intoxication of enthusiasm. A youthful madness took possession of them. Those squadrons which I saw flying overhead while it was still dark on Thursday morning did daredevil, reckless, almost incredible things. They flew as men inspired by passion and a fierce joy of battle. They were hunters seeking their prey. They were Berserkers of the air, determined to kill though they should be killed, to scatter death among the enemy, to destroy him in the air and on the earth, to smite him in his body and in his works and in his soul by a terror of him. This may seem language of exaggeration, the silly fantasy of a writing-man careless of the exact truth. It is less than the truth, and the sober facts are wild things. Early on June 7 they were up and away, as I described them, passing overhead on that fateful morning before the crimson feather clouds appeared over the battlefield. They flew above German railway stations far behind the lines, and dropped tons of explosives, blowing up rolling stock, smashing rails and bridges. They attacked German aerodromes, flying low to the level of the sheds and spattering them with machine-gun bullets so that no German airmen came out of them that day. One man's flight, told in his own dry words, is like the wild nightmare of an airman's dream. He flew to a German aerodrome and circled round. A German machine-gun spat out bullets at him. The airman saw it, swooped over it, and fired at the gunner. He saw his bullets hit the gun. The man ceased fire, screamed, and ran for cover. Then our airman flew off, chased trains and fired into their windows. He flew over small bodies of troops on the march, swooped, fired, and scattered them. Afterwards he met a convoy going to Comines, and he circled over their heads, hardly higher than their heads, and fired into them. Near Warneton he came upon troops massing for a counter-attack, and made a new attack, inflicting casualties and making them run in all directions.
