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.

Guynemer had frequently used this maneuver, but he preferred a front attack, thinking that if he should fail he could easily resort to the other, either by turning or by a quick tail spin.  So he tried to get between the sun and the enemy; but as ill-luck would have it, the sky clouded over, and Guynemer had to dive down to his opponent’s level, so as to show him only the thin edges of the planes, hardly visible.  But by this time the German had noticed him, and was endeavoring to get his range.  Prudence advised zigzagging, for a cool-headed gunner has every chance of hitting a straight-flying airplane; the enemy ought to be made to shift his aim by quick tacking, and the attack should be made from above with a full volley, with the possibility of dodging back in case the enemy is not brought down at once.  But Guynemer, regardless of rules and stratagems, merely fell on his enemy like a cannon ball.  He might have said, like Alexander refusing to take advantage of the dark against Darius, that he did not want to steal victory.  He only counted on his lightning-like manner of charging, which had won him so many victories, and on his marksmanship.  But he missed the German, who proceeded to tail spin, and was missed again by Bozon-Verduraz, who awaited him below.
