I remember a notable first trip across the lines made by a pilot who had just arrived from England. He had been sent up to have a look at the battle line, with an old-hand observer and instructions not to cross the trenches. However, he went too far east, and found himself ringed by Archie bursts. These did not have their customary effect on a novice of inspiring mortal funk, for the new pilot became furiously angry and flew Berserk. He dived towards Bapaume, dropped unscathed through the barrage of anti-aircraft shelling for which this stronghold was at the time notorious, fired a hundred rounds into the town square from a height of 800 feet, and raced back over the Bapaume-Pozières road pursued by flaming "onion" rockets. The observer recovered from his surprise in time to loose off a drum of ammunition at Bapaume, and three more along the straight road to the front line, paying special attention to the village of Le Sars. It was above this village that I once was guilty of communicating with the enemy. During a three-hours' offensive patrol around the triangle--Bapaume-Mossy-Face Wood-Epehy--we had not seen a single Hun machine. Low clouds held Archie in check, and there was therefore small necessity to swerve from a straight course. Becoming bored, I looked at the pleasant-seeming countryside below, and reflected how ill its appearance harmonised with its merits as a dwelling-place, judged on the best possible evidence--the half-hysterical diaries found on enemy prisoners, the bitter outpourings anent the misery of intense bombardment and slaughter, the ominous title "The Grave" given to the region by Germans who had fought there. An echo of light-hearted incursions into German literature when I was a student at a Boche college suggested that the opening lines of Schiller's "Sehnsucht" were peculiarly apposite to the state of mind of the Huns who dwelt by the Somme. Wishing to share my discovery, I wrote the verse in large block capitals, ready to be dropped at a convenient spot. I took the liberty of transposing three pronouns from the first person to the second, so as to apostrophise our Boche brethren. The patrol finished, my pilot spiralled down to within a 300-yard range of the ground and flew along the road past Martinpuich, while I pumped lead at anything that might be a communication trench. We sprinkled Le Sars with bullets, and there I threw overboard the quotation from a great German poet, folded inside an empty Very's cartridge to which I had attached canvas streamers. If it was picked up, I trust the following lines were not regarded merely as wordy frightfulness: "Ach! aus dieses Thales Gründen Die der kalte Nebel drückt, Könnt' ihr doch den Ausgang finden, Ach! wie fühlt' ihr euch beglüekt!"
