The film is in full color and uses no actors, making it a valuable historical document. The documentary showed more gruesome scenes of battle than other war films to date. According to the documentary The War, President Roosevelt himself gave approval for showing the film, against the wishes of many advisers.
Since the pictures were far too graphic to meet the standards of Hollywood producers and distributors, only the President could grant permission for its release to the general public. President Roosevelt consulted the only man who was present at the Battle of Tarawa that he personally knew and trusted, Time-Life photographer Robert Sherrod. Quoting Sherrod, “I tell the President the truth. Our soldiers on the front want people back home to know that they don’t knock the hell out of them every day of every battle. They want people to understand that war is a horrible, nasty business, and to say otherwise is to do a disservice to those who died.” Based on Sherrod’s prompting, FDR agreed to release the film, uncensored.
The film won the 1945 Academy Award for Best Documentary Short Subject.
