They flew wonderfully, being all picked men, and in a fight they performed in a manner which would have seemed impossible to the most expert aerial acrobats.

Also, the squadron was moved from place to place as a self-contained unit, so that it appeared wherever the fighting was thickest, or wherever British or French reconnaissance machines were busiest. It would be operating at Verdun one week. The next week it would be north of Arras. A few days later it would be down on the Somme. But as a rule it specialized on the British front. Wherever it pitched its tents it did its regular squadron performance, and followed it later in the day with lone-hand raids, or "strafing" flight by two or three machines at a time.

When one considers the harlequin coloring of the machines, their acrobatic flying and their "two shows a day" performances from their one-week pitches, it follows logically that the humorists of the R.F.C. simply had to call the squadron "von Richthofen's Traveling Circus."

Since then the word has acquired a meaning of its own among flying men. It connotes practically any special formation organized for the purpose of hunting enemy aviators, and consisting of picked men under a specially skilful leader. It need not necessarily be more mobile than any other squadron, and it need not indulge in freak colorings, though in the nature of its work, its flying must be acrobatic. The British "circuses" are in these days superior to the German circuses, because our machines are now at least as good as those of the Germans, and so our men, who have always been of higher average quality than the German aviators, have a fair chance of proving their worth.

Of those of von Richthofen's circus mentioned in the book, Schäfer was the first to be killed. Before the war he lived in London, to learn English, working in an office in the city, when so inclined, but mostly spending his time on the river, or in sport. Those who knew him say that he was a pleasant lad and a good sportsman.

Voss was the next to go, after what has been described by those who were in it as one of the most gallant fights of the war. On a Fokker triplane with a French le Rhone engine—evidently an experimental machine built for quick manoeuvring—he fought single-handed a patrol of six of our people, when he could have broken off the fight and have got away by abandoning an inferior companion. He was a brave man and a most brilliant pilot. His flying and shooting in his last fight are said to have been marvelously clever. None admire his bravery more than those who fought him.

Others of the "circus" have fallen since then, and the present "Richthofen Jagdstaffel" is probably constituted very differently from that band of high-spirited desperadoes which was evolved from the original Boelcke squadron, and helped to build up the fame of von Richthofen. There is none of the old R.F.C. who would not cheerfully kill what is left of the "circus," and there is probably none who would not gladly shake hands with the survivors after peace is declared. They are worthy enemies and brave men.

This little book gives one a useful insight into the enemy's methods, and more than a little respect for at any rate some of those whom we are at present endeavoring to kill.
