There is a brief author's note at the beginning of the book:
The task force movements, beachhead assaults and principal enemy air attacks described in this novel are intended to be historically accurate, and in other respects the author has attempted to tell a story which will ring true to veterans of amphibious landings.
All characters in this story are fiction and any resemblance to actual persons is coincidental. The U.S.S. Belinda is imaginary; there was no attack transport by that name. Many other ships in the story never actually existed, yet it is the author's desire that in these pages the reader will recapture the spirit of those ships of the United States Navy which sailed to victory through the Pacific islands.
A song that is alluded to in the book, and which plays a part in the 1956 movie based on it:
The movie, incidentally, had a very brief, uncredited, speaking role by the young Clint Eastwood.
