This is what the Reviewers are saying:

“This is the most important book published on the Great War this year.”  Peter Hart – full review here.

“It ranks with HA Jones’ classic War in the Air volumes as a resource and is indispensable for future writing about British and related American air operations in World War I.   Henshaw’s book is without peer.  Peter Kilduff – full review here

“A truly astounding work.  This book represents a milestone… based on its very breadth and authority” Mark Barnes, on War History Online – full review here

“A reference work of enormous breadth and depth. …he has also referenced thousands of German records in order to confirm Allied losses.  The information within this book is staggering… a treasure trove of information.  …A book of such richness and gravity.”  Major Chris Buckham, Royal Canadian Air Force, on The Military Reviewer – full review here 


This is a site to illustrate a project that I have worked on for many years – the expansion and complete update of my original The Sky Their Battlefield – the story of 16,700 British, Commonwealth and American airmen of the Great War.

These pages describe all the new content I’ve found and assembled.

Twenty years of continuing and wider research, since The Sky Their Battlefield first appeared in 1995, has probably resulted in the book I originally sought to write. Air fighting and the air casualties of the Great War remain my book’s universal focus, across specific details of over 7,600 individual incidents (of which almost 6,000 have been expanded or added), but its scope has now been widened greatly. The new TSTB2 is now in two parts: the first is a really thorough update and expansion of all the original content, and thus continues to concentrate on Allied air casualties due to enemy action. In addition however, The Sky Their Battlefield II now also incorporates sections covering almost 3,300 additional Allied air accidents of the Great War era, in the Accidents Addendum.

The links at the top take you to some sample pages, and some more in-depth information about the content of my book.

And here’s some more background about me – click here.
