All at once he was really resolved. _Sous-lieutenant_ Bozon-Verduraz was requested to accompany him, and the mechanicians wheeled the machines out. One of his comrades asked with assumed negligence: "Aren't you going to wait till Major du Peuty and Major Brocard arrive?" Guynemer's only answer was to wave towards the sky then freeing itself from its veils of fog as he himself was shaking off his hesitancy, and his friend felt that he must not be urgent. Everybody of late had noticed his nervousness, and Guynemer knew it and resented it; tact was more necessary than ever with him. Let it be remembered that he was the pet, almost the spoiled child, of his service, and that it had never been easy to approach him. Meanwhile, the two majors, who had been met at the station, were told of his nervous condition, and hurried to speak to him. They expected to reach the camp by nine o'clock, and would send for him at once. But Guynemer and Bozon-Verduraz had started at twenty-five minutes past eight. They had left the sea behind them, flying south-east. They had reached the lines, following them over Bixchoote and the Korteker Tavern which the French troops had taken on July 31, over the Bixchoote-Langemarck road, and finally over Langemarck itself, captured by the British on August 16. Trenches, sections of broken roads, familiar to them from above, crossed and recrossed each other under them, and they descried to the north of Langemarck road the railway, or what used to be the railway, between Ypres and Thourout and the Saint-Julien-Poelkapelle road. No German patrol appeared above the French or British lines, which Guynemer and his companion lost sight of above the Maison Blanche, and they followed on to the German lines over the faint vestiges of Poelkapelle. Guynemer's keen, long-practiced eye then saw a two-seated enemy airplane flying alone lower down than himself, and a signal was made to attract Bozon-Verduraz' notice. A fight was certain, and this fight was the one which Fate had long decided on. The attack on a two-seater flying over its own lines, and consequently enjoying unrestricted freedom of movement, is known to be a ticklish affair, as the pilot can shoot through the propeller and the passenger in his turret rakes the whole field of vision with the exception of two angles, one in front, the other behind him under the fuselage and tail. Facing the enemy and shooting directly at him, whether upwards or downwards, was Guynemer's method; but it is not easy on account of the varying speeds of the two machines, and because the pilot as well as the passenger is sheltered by the engine. So it is best to get behind and a little lower than the tail of the enemy plane.
