Punctuation and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed.

Simple typographical errors were corrected; occasional unbalanced quotation marks retained.

Ambiguous hyphens at the ends of lines were retained; occurrences of inconsistent hyphenation have not been changed.

In this version of this eBook, dashes between multiple locations and within numeric ranges are shown as en-dashes (–), which are longer than hyphens (-) but shorter than em-dashes (—).

Index not checked for proper alphabetization or correct page references.

Page 99: “Ronar’ch’s” is a misprint for “Ronarc’h’s”.

The Order of Battle lists beginning on pages 97 and 199 are in the same sequence as in the original book, but the side-by-side Allied and German units often do not align as they did in the original.

Page 272: The Index reference to General Gallieni and the battle of the Ourcq did not include a page number.
