Minor typographical errors have been corrected without note.
Punctuation and spelling were made consistent when a predominant
form was found in this book; otherwise they were not changed.
Ambiguous hyphens at the ends of lines were retained.
Mid-paragraph illustrations have been moved between paragraphs
and some illustrations have been moved closer to the text that references them. The List
of Illustrations paginations were changed accordingly.
The illustrations captioned "Some of the Men of the American
Ambulance Field Service at their Headquarters, 21 Rue Raynouard, Paris" and
"Croix de Guerre" are both listed as being on page 278. This was not corrected.
The entry in the Contents page "letter from Section Leaders xix"
is not matched by an entry in the text.
Corrections:
p. 3: Crombec changed to Crombeke.
p. 111: Battle of Champarng changed to Battle of Champagne.
