The last fight of the French aviator occurred four or five miles inside the German lines northeast of Ypres and opposite the British lines. Captain Guynemer was accompanied by Lieutenant Bozon Verduraz, who says that they were flying at a height of 15,000 feet when Guynemer sighted an enemy two-seater, which he attacked. Almost at the same moment Verduraz saw four German monoplanes approaching and turned toward them instantly so as to draw them off. They circled around for a while and then disappeared. Verduraz then returned to the place where he had left Guynemer engaged with the German biplane, but Guynemer had vanished.
