Footnotes, originally at the bottoms of the pages that referenced them, have been collected, sequentially renumbered, and placed at the end of the book.
The index was not checked for proper alphabetization or correct page references.
Original text uses two forms of the following words; both retained here:
- “moral” and “morale”
- “underwater” and “under-water”
- “minefield” and “mine-field”
- “seaplanes” and “sea-planes”
Redundant book title on [page 1] has been removed by Transcriber.
[Page 316]: The times in the illustration's heading use a mix of Roman and Arabic numerals.
[Page 360]: The time shown as “7.8” was printed that way. It may mean “8 minutes after 7”. Similar times appear on other pages.
