Guadalcanal Diary (book)

Guadalcanal Diary is a memoir written by war correspondent Richard Tregaskis and originally published by Random House on January 1, 1943. The book recounts the author's time with the United States Marine Corps on Guadalcanal in the early stages of the pivotal months-long battle there starting in 1942. It was the first book published by Random House to sell more than 100,000 copies.

Almost immediately after publication, the memoir was made into a movie of the same name featuring William Bendix, Richard Conte, Anthony Quinn, and John Archer, marking the movie debut of Richard Jaeckel.
