“Don Hale with the Flying Squadron” isthe third of the “Don Hale Stories.” It follows“Don Hale in the War Zone,” and“Don Hale Over There,” and tells what happensto Don after he relinquishes hisdangerous post as an ambulance driver forthe Red Cross on the western front.

But Don’s new duties are of a far moredangerous nature; and during his training inthe aviation school and after he finally becomesa full-fledged member of that mostfamous of all flying squadrons, the LafayetteEscadrille, he has interesting experiences andenough exciting adventures to last even themost spirited youngster an entire lifetime.

It may be safely said, however, that the accountis not overdrawn; indeed, in the airservice, in which most valiant deeds havebeen performed, it would be hard to exaggeratethe perils which beset the “cavalry of theclouds” on every side.

To add to the interest of Don’s experienceswith the escadrille there is a certain mysteryconnected with several characters which isnot solved until the end of the story.

In the next book of the series, “Don Halewith the Yanks,” is told the further adventuresof the young combat pilot after he hasbeen transferred to the American air service.He sees much of that memorable conflict—oneof the turning points of the great war—when,at Chateau Thierry, the German drivefor Paris was halted by the victorious Americans.
