No.10 Squadron of England's Royal Naval Air Service was formed at St. Pol, a suburb of Dunkerque, in February 1917, as part of the rapid naval aviation expansion programme required by the Royal Naval Air Service's commitment to assist the Royal Flying Corps on the Western Front. Seconded to the Royal Flying Corps and initially flying the "state of the art" Sopwith Triplane, the squadron's predominantly Canadian pilots established an enviable reputation and created the legend of the Black Flight that is still discussed today. A change in aircraft to the Sopwith Camel at the end of August, kept the squadron at the cutting edge of technology, but a major disagreement over carrying out the Royal Flying Corps orders resulted in an unscheduled return to Naval control in October. The squadron remained under Naval control until the April 1, 1918, when the Royal Naval Air Service and the Royal Flying Corps were amalgamated into the fledgling Royal Air Force. This volume provides the detailed history of this squadron?s activities, combat claims, accidents and fatalities, aircraft and markings, pilots, and ground officers.
