Continuing some reading of "specialized studies" on the Great War - had an interest in this book because of a general interest in military medicine history - also as a modeler, as I have the ICM 1/35 Model T Ambulance on my wish list.
Good book - author first covers the genesis of the volunteer ambulance services in France including the internecine competition among various units as well as the unimaginable bureaucracy and lack of cooperation from the French and British.
Favorite part was "Part II" - "Works and Days" - which described the dangers the drivers faced, their desire to be closer to the action, what they did in their off time, and - especially - details on "the cars," most especially the versatile Model T
The final part dealt with some of the more famous drivers (Hemingway, etc) and dispensing with conventional wisdom on some others (e.g., Walt Disney), and the heroics of female drivers, as well as the "militarization" of the volunteer units as they were absorbed by the US Army when America entered the war - and, again, the (often) petty rivalries among some of the principal leaders of the various volunteer units.
Good research and useful bibliography - I think I will chase down some of the driver memoirs that are referenced in the book - thoughtful Foreword by George Plimpton - good and relevant illustrations/photographs
As good as the book is, it's still rather thin at only ~175 pages of text, the rest being Notes/Bibliography - still worthy of a more expansive treatment, I think
